  • Solving for Math Success

    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.

    Every minute counts: How districts govern teacher time

    Teachers’ time is one of our most precious resources in schools. To design policies that make the best use of time to support teacher effectiveness, it’s helpful to see how school districts allocate it and how that compares across the country.

    Roll Call 2020
  • Teacher Leave & Benefits
  • Roll Call 2020

    Teachers accomplish so much each day, that any day that they are absent means lost learning for their students. In this report, NCTQ explores the importance of teacher attendance; examines teacher attendance trends across 30 of the largest school districts in the nation; and identifies patterns and connections that surround teacher absenteeism, such as a connection between central office and teacher attendance, and correlations between teacher attendance and teacher characteristics such as tenure and years of experience. The study is an update to NCTQ’s 2013 Roll Call report.

    July 2016: How much time do teachers get to plan and collaborate?

    In order to be well prepared for daily instruction, teachers
    need time without students to plan and collaborate. This month, Trendline delves into how long the teacher workday is and how much of that time
    is devoted to planning and collaboration.

    Myth Busters: Scholar asserts reports on American teachers’ teaching time are grossly exaggerated

    Myth Busters: Scholar asserts reports on American teachers’ teaching time are grossly exaggerated

    The myth: U.S. teachers spend upwards of 50 percent more time in front of their students than teachers in
    other countries (see more examples of this myth here,
    here
    and here).

    The
    reality:
    They don’t. A new studydigs into why survey data incorrectly suggest that our
    teachers spend so much more time teaching a classroom of students (as opposed
    to other kinds of activities such as 
    planning, classroom duty and tutoring students, which are counted
    separately) than teachers in other countries.
    The graph above depicts teachers’ responses to the survey question used
    to gather U.S. data on teaching time–notice a pattern?
    The question intends for teachers to add up how much time they spend
    teaching each week and then round to the nearest hour. The responses spike at
    intervals of five, suggesting that teachers estimated the amount of time they
    teach each day to the nearest hour and multiplied by five (for the five
    instructional days in the week), leading to an inflated amount of teaching
    time.
    For example, teachers who teach five 45-minute classes a day should have
    reported 19 hours of teaching per week, but instead reported 25 hours, rounding
    a 45-minute period to an hour.

    This error of rounding seems to explain why, year after year, the OECD’s
    Education at a Glance reports that U.S.
    teachers spend significantly more time in front of their classrooms than do
    teachers in other countries.
    Another reason to
    suspect the reported amount of teaching time is inflated? About a quarter of
    the survey respondents reported teaching their students more hours than the
    length of the school day itself.

    We’ve thought a lot about the strike in Chicago over the last nine days. Today we took some time to look at the details of the contract and the sum of their parts. Is it good for kids? Does it move the district in the right direction?
