Based on teacher surveys and measures of teacher math knowledge, cumulated across all districts:
-There was evidence of a positive association between teacher math content knowledge and student performance on statewide tests
-The top benefits of TI-Navigator™ technology, from most teachers’ point of view, were more immediate feedback about what students know and can do and enhanced student conceptual understanding of mathematics.
-Teachers varied in the extent that they engaged students in extended discussion of their ideas. When they did engage students, most often discussion was part of whole-class instruction or review.
-Most teachers did use the TI-Navigator displays in their class so that students can see the distribution of responses to problems in class. Some used the data to speed up or slow down the pace of instruction.
