Instructional Time Spent on Mathematics
These exhibits present principals’ and teachers’ reports about the instructional hours per year that were spent on mathematics instruction. The principals provided the number of school days per year and the number of instructional hours per day, and the teachers provided the weekly amount of instruction in mathematics. As explained in “About the Measure,” the data were combined to estimate yearly amounts of instructional time in mathematics for each country. As might be anticipated, these estimates vary somewhat from the levels of instructional time set as a matter of policy.
