The NAS has published a long-buried study on the state of the history research paper in American high schools. The 2002 study sponsored by The Concord Review (TCR) went unpublished when its benefactor, the Albert Shanker Institute, found the results unflattering to high school teachers.
Why aren't high schools doing a better job of teaching students to write? The suppressed study finds that 95% of high school teachers think research papers are important, but 62% never assign them.
According to the report, the biggest barriers to teachers are time and class size. Most teachers said that grading papers took too much personal time, and that not enough time was provided for this in the school day. Teachers surveyed taught an average of 80 students each. Assigning a 20-page paper then means having 1,600 pages to grade. The Concord Review urged high schools to support teachers by providing more time for them to grade papers.
