Teacherscribe’s Teaching Tip #34
The Trouble with textbooks.
I’m stealing this from a book I read this summer for a graduate course on teaching reading in the content areas: Subjects Matter by Harvey “Smokey” Daniels and Steven Zemelman.
Trouble #5 – textbooks are often inaccurate
If you can believe this – “the Texas State Department of Education undertook a study of errors and factual inaccuracies in the mathematics textbooks that had been submitted by major publishers for use in its schools. They found a total of 109,263 errors in the math texts being considered for purchase” (Daniels and Zemelman, 2014, p. 56).
