    Math skills are critical for students’ success in other subjects and later in life, yet far too many teacher prep programs fail to give aspiring teachers the essential knowledge they need to be effective math teachers—undermining student learning before the first lesson even begins.

    Beware of the ‘Pupil Factory’

    Beware of the ‘Pupil Factory’

    For most students, the start of middle school represents
    some newfound independence. For the first time, they get to travel the halls
    from class to class without being led by an adult.
    Of course, this new freedom stems from how middle
    schools are set up. Few teachers have the training to teach every subject in
    the middle school curriculum so instead of having one primary teacher, there
    are at least four. Students find themselves traveling to the teachers, each a
    specialist in their subject area.
    There’s been a lot of debate over the years about when
    to introduce subject specialization. In fact many elementary schools introduce
    the model at 4th grade.
    But a strong new study from Harvard economist
    Roland Fryer calls into question that practice.
    Fryer conducted a two-year experiment in 50 public
    elementary schools in Houston, Texas. Half of the schools remained on a
    traditional elementary school schedule; in the other half, principals assigned
    teachers to teach specific subjects based on their observed strengths and
    previous value-added scores.
    For the most part, assigning teachers to specific
    subjects didn’t make much of a difference—and when it did, that difference was
    generally negative. Reading and math scores declined, while problem behaviors
    and absences actually increased—albeit to a small degree. Basic economic theory
    predicted an efficient assembly line in which every teacher installed her
    piece; reality told another story.
    It’s hard to know exactly why the experiment didn’t
    have better results. Perhaps teacher specialization would have a positive
    impact if teachers received extra training in their assigned subjects. Perhaps
    lost time getting to know each individual student eliminates any benefits that
    could come from specialization.
    Regardless of the cause, the results serve as a
    helpful reminder that elementary
    teachers need a strong grounding in all four traditional content areas, not
    just the ones they’re more drawn to, as principals can’t simply
    rearrange staff based on interest or inclination and expect better student outcomes.
    Further, Fryer’s study is robust, using a large sample size, multi-year
    implementation, sound experimental design, and realistic policy implementation.
    As this study failed to find a benefit to teacher specialization in Houston’s elementary
    schools, it’s unlikely that other districts would fare better.

    Teacher diversity: Grounding our goals in reality
  • Teacher Diversity
  • Teacher diversity: Grounding our goals in reality

    One feature of an ideal school environment, we
    believe, is that both students and their teachers reflect America in all of its
    diversity. Everyone, including children coming from privilege, benefits from a
    diverse school experience.
    It’s no wonder that as the minority student
    population has grown in numbers in the past few decades, surpassing 50 percent,
    so many of us are troubled that the minority teacher population has failed to
    keep pace, standing now at only 18 percent minority. The push to achieve racial
    parity between teachers and students has never been stronger, with urgent calls
    from school boards, states, and even the U.S. Department of Education for the
    nation to make teacher diversity a top goal for school districts.
    This sentiment is understandable, commendable, but
    — at the risk of being a wet blanket — not even remotely achievable within the
    foreseeable future.
    No matter how you run the numbers, school districts
    simply cannot recruit and retain enough black and Hispanic teachers to achieve
    racial parity between the teacher workforce and the U.S. student body – no
    matter how many reprimands HR officials have to face from the their school
    boards for the paltry results.
    Researchers from NCTQ and The Brookings Institution
    recently analyzed what it would take to create a teaching workforce as diverse
    as the students it serves. You can find a full report of our analysis and
    findings here.
    We estimate the effects of different interventions
    that might increase the number of minority teachers, extrapolating population
    projections for the next four decades to see how close they can come to
    creating a racially representative teacher workforce.
    The findings are startling: parity or even
    significant inroads to parity will remain completely elusive unless we fire on
    all cylinders. If we can somehow boost the rates of college completion,
    interest in teaching, hiring, and retention so that these rates for black and
    Hispanic college students and adults mirror the rates of their white
    counterparts, then parity becomes an achievable goal – but is still several
    decades away.
    How can this be?
    Let’s walk through what we found, drawing on a
    model we built using U.S. Census projections and data about the current teacher
    and student populations to estimate the impact of various interventions.
    For example, let’s see where a big push on
    retention of black teachers gets us. Currently, 16 percent of America’s public school
    students are black, compared to 7 percent of teachers, creating a nine
    percentage point gap in the diversity of students and teachers.
    What could happen if schools took real and
    substantive steps to retain their black teachers so that year in and year out
    black teachers stay in the classroom at the same rate as white teachers
    (improving their current attrition rate from 10 percent to mirror white
    teachers’ 7 percent)? We still wouldn’t close the diversity gap even projecting
    out to 2060 (the furthest year of Census projections available).
    Next, imagine we committed ourselves heart, body,
    and soul (as many districts are, in fact, trying to do) to hire more black
    teachers. The rewards would be tiny even projecting all the way out to 2060.
    Okay, so what about persuading more black college
    students to consider teaching? Higher education could heavily promote teaching
    with undergraduates, or graduate programs and alternative providers could
    recruit more black candidates—something that many claim to be doing already.
    But let’s imagine pouring some real resources into these strategies, such as increased
    salaries, loan forgiveness, or more leadership opportunities to succeed in
    persuading black adults to consider teaching at the same rate as white adults (currently
    4.3 percent of black undergraduate students major in education compared with
    6.9 percent of white undergraduates; we see similar disparities for graduate
    college education degrees and alternative certification enrollment).
    Again, the results would be fairly paltry – closing
    the diversity gap by about two and a half percentage points by 2060.
    I’m guessing that a lot of people reading this are
    thinking “but look at the success of Teach For America, now recruiting new
    cohorts which are about 50 percent teachers of color?” TFA was able to achieve
    these huge gains in part because it developed unprecedented recruitment efforts
    of minority students beginning in their freshmen year—a great strategy to
    emulate. But keep in mind that the corps is tiny compared to America’s needs.
    Teach For America supplies less than 3 percent of the nation’s teachers. Its
    hard push on this problem still only produced about 800 new black corps members
    in a year. That’s enough to translate into significant gains for TFA, which is
    only recruiting some 4,100 teachers in a year, but remains a far cry from the
    300,000 more black teachers needed to achieve parity across all American
    schools.
    Let’s go back to the point of greatest disparity
    between black and white students: the college completion rate. If we invest
    heavily to support black students and ameliorate their low college completion
    rate so that they graduate college at the same rate as white students
    (currently 28 percent of black 22-year olds have earned a bachelor’s degree,
    compared with 47 percent of white 22-year olds), we still will not come close
    to closing the gap by 2060.
    Disheartening, no?
    For Hispanic teachers, the dismal scenario is much
    the same. In fact because the Hispanic population in the US is growing at such
    a fast rate, much faster than the black population, the diversity gap is
    expected to widen if we do not take action.
    Only if we are able to graduate more Hispanic
    teachers from college or draw more Hispanic adults into careers in teaching can
    we reduce the growing diversity gap significantly, otherwise expected to be 22 percentage
    points by 2060.
    Clearly, the answer is to combine all these
    interventions and be successful at
    all of them (success defined here as achieving the same rates as their white
    counterparts) to make any real dent. If over the next decade we were to improve
    college completion rates, interest in teaching, hiring, and retention to mirror
    that of white teachers at every point, we would actually achieve parity by the
    year 2044 for black teachers and students. The picture is less cheery for
    Hispanic teachers, only coming within the ballpark (three percentage points
    away from racial parity) by consistent pushes through 2060.

    So are we
    suggesting we all throw up our hands and give up on achieving greater parity?
    Absolutely not. But let’s not underestimate the ambition, commitment, and
    persistence needed, or browbeat school superintendents or human resources
    officials when they are only able to make incremental progress. Let’s also not
    advocate for racial parity at the expense of quality. The research is clear
    that students’ success still depends most on the quality of their teachers
    In the meantime, other important solutions can
    achieve greater equity in our schools. Let’s look for meaningful ways to ensure
    that teachers – who want to do right by their students – don’t unintentionally
    do harm to the kids who don’t look like them. Let’s go beyond the stuff of
    current trainings in which teachers and teacher candidates engage in a lot of
    reflecting on their implicit biases, analyzing their white privilege, or
    developing cultural sensitivity, much of which hasn’t had much impact –
    although these do play an important role. Let’s do more to have teachers
    examine their daily interactions with students by asking themselves: which
    students do they call on to answer questions? Are some students more likely to receive
    harsher disciplinary actions than others? Do they select some groups of students
    for more challenging work over others? Give teachers the training and tools to
    make sure that they do not allow their biases along race, gender, class, or any
    other lines to get in the way of helping every child thrive.

    A long fall to the bottom: Missing coursework in teacher prep
  • Elementary Math
  • A long fall to the bottom: Missing coursework in teacher prep

    You
    can’t teach what you don’t know—and
    when it comes to math, some teachers just don’t know enough.  Why?  

    Michigan
    State University professor William H. Schmidt and his colleagues look at the
    mathematics that American middle school teachers took during their teacher
    preparation and produce some hard evidence of prevailing substandard
    preparation.
    First
    though, recall some earlier
    work
    in which Schmidt examined how teachers were prepared in 16
    countries. There, he unearthed the essential knowledge for middle school
    teachers based on the relationship between coursework and teachers’ strong
    performance on an international assessment of math content knowledge and math
    pedagogical content knowledge. The top performing teachers had all studied nine
    topics, including linear algebra, calculus, probability, differential
    equations, functions/equations and also had opportunities to analyze math
    instruction.
    This latest study looks
    more closely at US preparation, examining how many US programs deliver this
    essential content. Even on this basic question, Schmidt finds enormous,
    inexplicable variations among institutions in what they consider to be
    essential content. Schmidt estimates that only about a third of America’s
    middle school teachers took coursework addressing this content. For the rest of
    teachers, a sizeable portion of the content never gets covered. Compare that to
    some of our international counterparts which include a number of countries
    where 80 percent of all teachers learned essential content.

    If you threaten, will they come?
  • Teacher Leave & Benefits
  • If you threaten, will they come?

    If half the battle is just showing up, some teachers have already lost the war.

    That’s what we learned in our 2014 study Roll Call: The Importance of Teacher Attendance. In 40 large school districts, we found that while most teachers come to work regularly, a significant number of teachers (44 percent across the districts) missed a heck of a lot of school—11 or more days in an average school year.
    Last month, the US Department of Education followed suit, releasing data that reinforces our findings. And, just like Roll Call, it revealed inexplicable differences among states, with Utah and South Dakota reporting relatively low rates of chronic absenteeism but others faring much worse, with 75 percent of teachers in Hawaii and 49 percent of teachers in Nevada missing more than 10 days per year.
    Neither NCTQ nor the Education Department data sheds light on why some schools struggle so much with this basic personnel practice. So there’s much to be said for new research from Seth Gershenson which unearths at least one device that improves teacher attendance: threat of sanctions.
    Looking at data from the early days of No Child Left Behind, Gershenson examines how K-5 teachers in North Carolina responded when their school failed to meet adequate yearly progress (AYP). Teachers in schools that failed to make AYP in 2003 significantly reduced their absences in the following year by about 10 percent. Chronic absenteeism (when teachers miss 15 or more days) fell by 20 percent.
    Not surprisingly, these declines in teacher absences translated to real gains in student achievement.
    NCLB was certainly not without its flaws, but this study serves as another reminder that strong systems of accountability lead to positive outcomes—and that every day a teacher spends in her classroom matters to her students. The challenge of teacher absences is unlikely to have a single solution, but we’re grateful for any additional insight.

    Picking your data battles
  • Teacher Evaluation
  • Picking your data battles

    Every great teacher knows that her grading practices need to be fair. And any good policymaker should know that teachers expect the same of their own performance evaluations.

    That’s one of the reasons why in 2014, the U.S. Department of Education offered states the option to delay using student growth data to evaluate teachers during the transition to new state standards and assessments. “These changes are incredibly important,” Arne Duncan
    explained, “and educators should not have to make them in an atmosphere of worry.”

    Still, many wondered: Would the new test scores
    actually
    have led to inaccurate value-added measures for teachers?
    To
    help settle the essentially theoretical question, Ben Backes and his colleagues
    examined value-added
    scores from before, during, and after states’ transition to new standards and
    assessments. The five-state study, conducted with support from CALDER, included
    changes that occurred during the Common Core era and as far back as 2001.

    The
    conclusion: assessment data from transition years would have produced the same
    evaluation results for teachers as the older tests.

    The
    researchers analyzed the data from multiple angles, including the correlation
    of value-added scores from year to year, the likelihood that a top- or
    bottom-ranked teacher in one year would rank in the same range the next year,
    and differences in teacher performance rankings by classroom type (advantaged
    or disadvantaged). All in all, transition-year math assessments performed about
    the same as in other years across all five states; in reading, two states saw
    slightly more variability during transition periods.

    It’s
    good news, but it doesn’t mean the one-year moratorium was a mistake. For
    teachers who were already skeptical of value-added in 2014, the message that
    transition-year data would likely be much the same as data from any other year
    probably wouldn’t have soothed any anxieties. A smart political decision, even
    if there was no crisis to avert.

    When it comes to teacher quality, do states really matter?
  • Teacher Licensure
  • When it comes to teacher quality, do states really matter?

    Of late, I’ve been holding my own internal debate. Is getting states to change their teacher policies worth all the time and effort that it takes x 50?

    For nearly a decade, NCTQ has taken an aggressive stance on the need to fix states’ teacher policies and we’ve had some great successes to boast about. Over that period, all but eight states have made significant improvements to their teacher policies. Yet, I’m still left with a nagging feeling that maybe these impressive changes aren’t having the game changing impact on teacher quality we anticipated. There’s all too much evidence of their derailment by school districts and teacher preparation programs.
    But I’ve now encountered new evidence of the harm that even seemingly innocuous state policies have on teacher quality. While state policies will never be the full answer, I’ve concluded, they must be an essential part of the equation.
    What’s that evidence? Last month we released a study looking at an array of essential content and skills that preschool teachers need but aren’t learning about in their teacher prep programs, skills like how to handle a disruptive four-year-old or how to build language skills and lay the foundation for learning to read.
    As we dug into why so much essential—and noncontroversial—content was missing from these programs, we hit on an interesting pattern. It turns out that the more grade levels any one prep program tried to cover in teacher training, the less likely a program was to deliver the content preschool teachers need.
    This chart explains more. It shows the big variations in grade spans among states for the purpose of certifying teachers. States, after all, don’t certify a teacher to only teach first grade but are more likely to certify a teacher to teach any elementary grade.
    In states like Mississippi and West Virginia, the state requires that preschool teachers have to train with only aspiring preschool and kindergarten teachers. Accordingly their coursework is more geared to that specialized content. In other states, however, it is acceptable for a single program to prepare teachers for anything from preschool to grade 6 (Texas) or even birth to grade 6 (Wisconsin), setting the same course requirements for everyone in the program. In Oregon, it is even possible for preschool teachers to train with teachers intending to teach 8th grade!
    It may be tempting to blame this problem all on the universities where the training occurs. After all state officials would be right in claiming that these teacher prep programs could choose to more narrowly train teachers no matter what state code dictates. They rarely do though.  It is surely considerably less expensive for a university to manage a one-size-fits-all program over several more narrowly focused programs.
    This is not just a higher ed problem however. Teachers love the flexibility of broad certifications, as they can teach more grades without having to go back to get recertified. Principals and districts love it even more because the staffing flexibility makes scheduling a lot easier. 
    I’ll never forget a conversation I had with some folks running what is largely regarded as one of the best STEM teacher prep programs in the country. They bristled at NCTQ’s criticism over the preparation of candidates under the state’s highly flawed general science certification. “We’re only giving the principals in this state what they want,” they asserted. “They only want science teachers who are certified to teach any science. They don’t really care that they’re not really all that well qualified.”
    That brings me to my second point.  The only entity that can claim disinterest here is the state and that’s often the case. To the state falls the responsibility to do what is right by teachers, because neither higher ed nor schools are apt to work against their own self interests. All of which brings me back to my original concern: what happens even if the state does the right thing? In this case, if Texas, Wisconsin and Oregon (to name a few of the worst offenders) were to adopt more narrowly defined certifications for training preschool teachers, would the problem be fixed? No, but it’s the first hurdle. The second hurdle is to get prep programs to change what they teach. A move by the state not only shifts the onus of responsibility to teacher prep programs but it sends an important signal that how we prepare teachers for our young children matters.

    Preschool teacher prep: illusions of quality
  • Teacher Prep
  • Preschool teacher prep: illusions of quality

    30
    million words. It’s a staggering number representing the tremendous gap in the
    number of utterances (
    not distinct words) a child hears by age
    four—depending on where his family falls on the socioeconomic spectrum.

    Preschool
    is regarded by many as the best opportunity for an early course correction,
    allowing all children to be launched on a successful
    academic—and life—trajectory no matter what is happening at home. Yet the jury
    is still out on whether preschool can deliver on that promise. Research on the
    long lasting contributions of preschool is at best mixed.
    There’s
    a lot of conjecture about why preschool investments may not
    pay off as much as one might expect: the length of the preschool, parents’ involvement,
    support services, low quality curricula, and poor oversight.
    One
    more plausible but largely ignored explanation remains: poor and/or
    uneven preparation of preschool teachers.

    While
    preschool teachers’ dismally low salaries have garnered lots of attention, even this week, there’s
    been little attention to the training given to preschool teachers before they
    enter the classroom.
    A new
    NCTQ study to be released next week explores whether programs are
    delivering essential content preschool teachers need. After all, beyond
    being patient and caring, preschool teachers must be able to learn
    and practice a wide swath of essential skills.
    Put
    more practically, when faced with the tremendous gaps in language skills in a
    classroom of 20 four-year-olds, how many of us would have an inkling of where
    to start?
    Many
    preschool advocates heavily champion the notion that all preschool teachers
    must earn a bachelor’s degree in order to guarantee sufficient quality. Some 33
    states now require that the preschool teachers in the programs they fund must
    have bachelor’s degrees.
    Though
    there’s been little hard research to help guide that requirement, states made
    what seemed like a safe bet, assuming that teachers who earn a bachelor’s
    degree are more likely to learn how to create a higher quality preschool
    environment than teachers who do not earn one.
    Yet,
    as it turned out, the assumption was just that, an assumption. 
    Our
    new study out on June 22nd, Some Assembly Required, takes a
    look at a healthy sample of 100 teacher preparation programs located in 29
    states. The vast majority of these 100 programs conferred
    degrees: 54 led to a bachelor’s degree and 41 to a master’s, as
    well as 5 at the associate’s degree level. We looked at course
    requirements, course descriptions, syllabi, student teaching handbooks,
    observation instruments, and textbooks to identify high-level evidence of key
    content.
    A review of these multiple factors reveals that almost all of these programs fail
    to reference even basic
    content needed for a teacher to learn how to build children’s language, a
    precursor to becoming a successful reader.

    In many programs, the instructional skills specific to the
    job of preschool teaching are marginalized, buried by other content only relevant to a teacher of later grades. Even on paper,
    programs do not claim to devote much—or any—time to training candidates in
    developing young children’s language skills and vocabulary or building critical literacy skills.

    It’s
    not just language and literacy that get short shrift. We found even less
    evidence of programs attending to the knowledge preschool teachers need to
    build math skills, explore early science concepts, or help children develop
    executive functioning skills. 
    We’re
    all for raising the bar for educators, especially those that play the crucially
    important role of teaching young children. A bachelor’s degree makes
    sense. But we need to make sure that the sheepskin earned by the preschool
    teacher stands for something relevant and valuable.

    The power of partnerships

    The power of partnerships

    In the face of all evidence on the (apparently) utter uselessness of most professional development, might there be something that works? A new NBER working paper claiming just that perked up our ears.

    Researchers John Papay, Eric Taylor, John Tyler, and Mary Laski employed a relatively simple approach. High- and low-performing teachers in Tennessee were paired together based on their professional strengths and weaknesses and then asked to spend a year developing the low-performer’s skills that needed improving.
    That’s it.
    No new, mandatory meetings. No expensive coaches. No new policies. And cheap. The only real cost to schools was the time the teachers needed to work with each other—and even that was left to the discretion of each school.
    The results were astounding: in classrooms taught by low-performing teachers, students scored, on average, 0.12 standard deviations higher than students in the control classrooms. To put that in perspective, the authors compare this improvement to what you would expect from a student assigned to a teacher ranked at the median rather than in the bottom quartile—or to an experienced teacher rather than a novice teacher. There was also evidence to suggest that the gains in teacher performance persisted or even grew in the year after the partnership was completed.
    Might this be a one-hit wonder? After all, it only looked at 136 teachers who all taught in the middle grades. A study of the impact on a larger sample is in the works. For the cost, though, we think it might be worth a try elsewhere!

    Over the last few decades, the field of teacher education
    has heavily promoted the use and even the mandatory adoption by states of

    can deliver a lesson. The push has come with a promise that these

    training on how to plan and deliver instruction far better than the home-grown
    efforts used by most programs.

    2. 
    They identify the quality of candidates and
    therefore can serve a gatekeeper for entry into the profession.

    3. 
    They provide information which states could use
    in the aggregate to hold programs accountable for their training.

    We concluded four
    years ago
    that the edTPA adequately fulfills the first function. TPAs are
    an exponential improvement over the rubrics and observation forms most programs
    use to assess a “live” lesson.

    A new
    study
    from three researchers at CALDER (Dan Goldhaber, James Cowan, and Roddy Theobald) provides evidence
    on this second function—whether TPAs actually identify the more capable
    candidates who deserve to be entrusted with a classroom of children.  That’s long overdue given the pressure that
    AACTE and others have put on states to adopt an instrument without any evidence
    that it was predictive of teacher performance.

    As was widely
    reported in the press last week
    , results from graduates of teacher prep
    programs in Washington state (one of the first states to adopt the edTPA) are
    mixed. Goldhaber et al. found that a passing score in the reading portion of
    the edTPA is significantly predictive of teacher effectiveness in reading, but
    not in the math portion.

    Given that the edTPA is a lot of work for programs and is
    costly to boot, is this enough bang for the buck? After all, instructions for
    candidates entail 40 pages and candidates are alerted that they can be
    evaluated on the edTPA on nearly 700 different items. The process consumes the
    attention of teacher candidates and teacher educators in their programs for a
    good share of candidates’ semester-long student teaching placement. 

    There’s a strong argument that the complexity is merited if
    it prevents unqualified persons from teaching—unless the same results could be
    had with a lot less time and investment.  A recent
    study
    on the measures employed by District of Columbia Public Schools to
    screen its teacher applicants indicates that one of the components with
    predictive validity is simply a 10-minute audition. A few more studies with
    similar results may make it difficult to justify blanketing the nation with edTPA
    requirements.
    That leaves the third function: program accountability. According
    to Goldhaber, the variation of scores of candidates within Washington programs is greater than the variation of scores across programs. This result, which
    Goldhaber did not publish, means that all but the most egregiously low performing
    programs are likely to have candidates whose scores vary considerably across
    the range.  

    The bottom line to date in this still-unfolding story about
    TPAs: the edTPA 1) is a good organizing vehicle for training, 2) may produce
    scores that at least partially discriminate among candidates in terms of
    effectiveness—but through a process that appears to be unnecessarily
    cumbersome, and 3) may produce scores that cannot be used to hold programs
    accountable because they are insufficiently related to the quality of candidate training.

    A drummed up teacher shortage crisis
  • Teacher Workforce Data
  • A drummed up teacher shortage crisis

    Isn’t it amazing how someone or some things gain traction when the facts clearly aren’t on their side? 
    Just like the media handed off most of its airtime and column inches to elevate Donald Trump’s candidacy, so too is the media guilty of announcing a crisis in teacher supply when the facts just don’t support it. 

    While there are no data to suggest we are in the midst of teacher shortage, there are certainly school districts that are experiencing real problems—but they’re largely the same school districts which have been struggling for years, even in times the media was reporting big teacher layoffs.

    There are some data to suggest that enrollment has dropped considerably in some teacher preparation programs in some states. But as we’ll show, it’s a big leap to say that the drop in enrollment means there won’t be enough teachers.

    These two graphs from economist
    Dan Goldhaber illustrate the importance of taking the long view.



    This first graph does indeed
    show that the number of new teachers produced since 2008 has declined. But keep
    in mind that that drop was preceded by a
    three-decade
    period of enrollment growth
    , far outpacing the demand year-in and year-out
    (as the second graph shows). America’s 1,450+ institutions which train teachers
    have been OVER-enrolling for years.

    The current decline is what we
    normally see when unemployment dips and the pool of folks looking for work
    isn’t as large as in other years.

    And as programs have not traditionally
    seen it as their responsibility to direct candidates to shortage teaching areas
    (e.g. special ed), there continue to be massive misalignment between the types
    of teachers trained and the types of teachers public schools need to hire.

    Most notably, programs have been
    routinely graduating twice as many new elementary teachers as public schools
    hire each year.

    Even when confronted with these
    facts, many districts have begun to panic. In part they have grown accustomed
    to dealing with a pretty distorted labor market and the low quality of many
    teacher candidates. They’re used to having to sort through a pile of resumes to
    find a single good hire. They are also often not nimble or flexible enough to
    adapt their recruiting and hiring practices to a tighter job market.

     What then is a reasonable response to a
    downturn in teacher production?  It’s not
    to open the floodgates and let just anyone teach. We need to continue to
    encourage teacher prep programs to become more selective and do a better job
    preparing new teachers so that districts don’t have to count on 20 resumes to
    find a single qualified teacher.

    Districts would do well to tap
    into the enormous pool of the many hundreds of thousands of people who were
    certified to teach but never did. Some estimates put the percentage of new
    teacher graduates who don’t actually teach at 50 percent. Neither states nor
    districts make it easy for those folks to reconsider the profession a few years
    down the road.

    A glimmer of hope on the bleak PD front

    A glimmer of hope on the bleak PD front

    The headline of a new study from Matthew A. Kraft (Brown University) and David Blazar (Harvard Graduate School of Education) caught our eye: Intensive, personalized coaching programs can improve teacher performance substantially.

    Professional development that works? Well… perhaps.

    The two researchers examined New Orlean’s yearlong adaptation
    of a coaching program from Boston-based MATCH School. Participants spend a week
    in a summer workshop followed by four one-week sessions of observation and
    feedback. Importantly, the participants teach a range of grades and subjects,
    distinguishing the program from more common coaching interventions that focus
    on early literacy.

    Teachers who got the coaching scored significantly higher
    than the uncoached teachers on an index of teacher quality that includes
    classroom observation scores, principal evaluation, and student surveys. In
    fact, the impact of having been coached exceeded even the impact of a teacher
    gaining more experience. The difference between coached and uncoached groups
    was nearly 50 percent higher than the difference between novice and experienced
    teachers.

    Coached teachers outperformed uncoached teachers by 0.59 standard deviations. For comparison, experienced teachers (3+ years experience) outperformed novice teachers (1 or 2 years experience) by a smaller margin of 0.44 standard deviations.

    Despite relying on a generally strong methodology, the size of the sample involving only 30 matched pairs tones down our enthusiasm a tad. But more importantly, the sample is restricted to teachers from urban charter schools who wanted to participate in the program—meaning that this approach may not translate well to other settings or less willing groups of teachers.

    Still, given how little we know about how to help teachers improve, even preliminary evidence of some ways professional development might become more effective is noteworthy.

    In memory of Barry Kaufman

    In memory of Barry Kaufman

    On behalf of the entire Teacher Preparation Strategies team, I want to express our sadness at the death of Barry Kaufman and our condolences to his wife of 50 years, Gail. Barry provided NCTQ with invaluable assistance for close to six years as a member of the Technical Panel for the Teacher Prep Review. Barry’s expertise—gained from serving as an ed school dean and as a member of the California Commission on Teacher Credentialing—was combined with an unwavering commitment to improve teacher preparation. He always made himself available to NCTQ staff for consultation and helped us to ensure that the picture of teacher prep painted in NCTQ reports is accurate. We will miss Barry’s endless goodwill and spot-on advice!

    A fault in our measures? Evidence of bias in classroom observations may raise some familiar concerns
  • Teacher Evaluation
  • A fault in our measures? Evidence of bias in classroom observations may raise some familiar concerns

       

    A
    lot of us can rattle off the possible shortcomings of using value-added test
    scores to evaluate teachers: The scores vary from year to year. They lack
    transparency. They cannot control for other events going on in the classroom,
    like broken air conditioning or teachers consistently being assigned
    exceptionally motivated students.
    Sad
    to say, these problems aren’t relegated to the statistical wizardry behind
    VAM—it turns out classroom observation scores may suffer from many of the same
    ills.
    New
    research from Matthew
    Steinberg of the University of Pennsylvania and Rachel Garrett of the American
    Institutes for Research employed data from the Methods of Effective Teaching study to look at how classroom
    composition relates to teachers’ observation scores.
    First,
    they found that teachers who were assigned to high-performing students were
    more likely to earn higher observation scores. They also found that some
    domains of the evaluation instrument used in this study (the Danielson framework)
    appeared to give teachers undue credit for traits, achievement levels, and
    other factors students arrived with at the start of the school year; domains
    like “engaging students in learning” and “establishing a culture for learning,”
    which rely heavily on student-teacher interaction, were the primary culprits.
    The authors offer two competing hypotheses for these higher scores: they could
    be a sign of observer bias—meaning, for example, that a teacher might get a
    score boost for having an eager and well-behaved class, even if she basically
    inherited her students that way—or they could indicate that teachers either
    perform or become better when working with a class of higher-achieving
    students.
    Finally,
    teachers who teach multiple subjects, like most elementary teachers, had observation
    scores that were less related to their students’ incoming achievement—unlike
    the scores for teachers who only teach a single subject (and therefore older
    grades). This difference could be because teachers’ observations in older
    grades are spread across multiple classrooms, or because teachers who spend
    more time with one group of students are better able to adjust to their needs.
    So,
    would Steinberg and Garrett’s findings hold true elsewhere? After all, the MET
    study observation data relied on an unusually robust approach to teacher
    evaluation, using highly-trained off-site evaluators who rated videotapes of
    lessons. In contrast, districts more often rely on in-person observations,
    often by school principals and APs.
    Unfortunately,
    the findings from more typical on-site evaluations by school administrators may
    look even worse, according to
    Whitehurst, Chingos, and Lindquist
    . These Brookings researchers tackled
    the observation issue a few years ago and found that outside observers produce more valid observations than school
    administrators—so Steinberg and Garrett’s work could actually understate the
    problem.

    Academic vs. non-academic outcomes: a troubling trade-off
  • Teacher Evaluation
  • Academic vs. non-academic outcomes: a troubling trade-off

    Earlier this year, the Every Student
    Succeeds Act (ESSA) launched “nonacademic factors” into the national
    discussion, as such factors can now be used as part of school accountability
    metrics. As states explore which factors to use, they may want to consider a
    recent
    working paper that finds that teachers who are rock stars at raising
    student test scores may not be the same ones whose students are either
    well-behaved or even particularly happy.

    Using a large sample of upper
    elementary classrooms across four districts, David Blazar of Harvard University
    and Matthew A. Kraft of Brown University examine teacher influence on math test
    scores and students’ self-reported behavior, self-efficacy, and happiness in
    math class. Their work revealed not only that teachers do indeed have a
    significant effect on non-tested outcomes, but also that the teachers who are
    most effective at improving test scores are not necessarily the same teachers
    who are most effective at improving non-tested outcomes—echoing the findings of
    another recent study.

    Although Blazar and Kraft don’t take
    a stand on incorporating measures of non-tested outcomes into teacher
    evaluations, their findings highlight the potential difficulty of doing so. In
    the sample, more than a quarter of the most
    effective teachers (based on test scores) were among the least effective when evaluated using student non-tested outcomes.
    To further complicate matters, the
    non-academic outcomes don’t always correlate. For example, teacher scores on
    classroom organization had a positive correlation with student behavior but a
    negative correlation with happiness in class.
    These contradictory findings are
    problematic since many of these factors influence long-term outcomes. Could it
    be that teachers improve one important student outcome at the expense of
    another? Or does this study highlight the complexity of the student experience
    and the challenges of measuring it with a survey?
    Clearly, this study raises more
    questions than it answers.

    Charterizing Teacher Prep?
  • Teacher Prep
  • Charterizing Teacher Prep?

    Of late, there’s been a lot of chatter among
    teacher educators objecting to language in ESSA for “teacher preparation
    academies,” relatively regulation-free routes into teaching. From the
    perspective of much-maligned traditional teacher prep providers, it’s the feds
    once again showing an unfair preference for alternative providers. The action
    stings all the more because they see academies as an unproven model, an
    objection with some merit in our eyes.

    So what gives?
    In return for escaping from most regulatory
    requirements (such as the coursework that must be taught), teacher prep
    academies would be held accountable for “the performance of their graduates,” which
    has yet to be defined. In effect, this trade-off is similar to the deals
    offered to K-12 charter schools—hence teacher educators’ christening of
    academies as “charterized” teacher prep.
    We have two questions: is this trade-off
    realistic (i.e., practical), and is it fair?
    Thinking of lessons to be learned from the early
    days of the charter movement, there was a time, long before No Child Left
    Behind, when schools offered up student performance results based on their own
    definitions of accountability. The data weren’t always pretty and, in fact,
    were sometimes nearly meaningless. It was only after data were standardized and
    disaggregated that any degree of accountability was achieved and useful
    insights began to emerge about promising models for school reform.
    Data available on K-12 schools are light years
    ahead of data on ed schools. In a recent report, Chaos to Coherence, Deans for Impact (a group of reform-minded ed
    school deans) examined seven different data categories—things like completer
    surveys, employer surveys, classroom observations, student achievement, and
    teacher evaluation of graduates—and documented the disappointing degree to
    which even the most progressive programs capture such data. 
    So the rub is that ESSA essentially allows
    states to hold academies accountable in the midst of a virtual data desert. Fewer
    than half of states have yet to define a “teacher of record” or require
    verification of class rosters—both fundamentals to hold academies accountable
    for the performance of their graduates.
    Further, long overdue regs on federal
    requirements for state data systems aren’t imminent: nearly four years into a
    rulemaking process that would help to close the black hole of accountability
    for teacher prep programs, there is no clear timeline for finalizing them.
    To answer our second question, proponents of
    these new academies claim that with the right incentives and rewards, providers
    will be highly motivated to fill the current data vacuum. But the current academies
    don’t strike us as poster children for transparency. For example, all that’s
    publicly available from Relay—perhaps the granddaddy of the academy movement—is
    summary data on self-selected metrics. While Relay can be applauded for posting
    this data, it is inadequate as a model for what should be collected and made
    available as a condition for breaking free of state regulation.
    Teacher preparation academies present a shiny
    new reason for collecting objective teacher performance data. It’s ironic then
    that the field of teacher education has consistently put up notorious
    resistance to such data, given that it could be the ticket for releasing them
    from the very regulations they find so burdensome.
