Capturing Teacher Knowledge (TeKno): Using Video Clips of Classroom Instruction as Item Prompts to Measure Teacher Knowledge of Teaching Mathematics
Investigator: Rossella Santagata (with PI Nicole Kersting and Karen Givvin, LessonLab Research Institute)
Funding: Institute of Education Sciences
This study examines relationships between (1) teachers' ability to analyze classroom teaching, (2) teaching practices, and (3) student learning. It develops a novel assessment for measuring teacher knowledge of mathematics teaching. This assessment uses online video clips of authentic mathematics instruction for teachers to view and analyze. Teachers are asked to comment on pedagogical and content related issues within the context of real classroom instruction.
Three video-analysis assessments will be developed, each addressing a key topic area within the upper elementary and middle school curriculum: (1) fractions, (2) ratio and proportion, and (3) variables, expressions, and equations. Score reliability and criterion-related validity will be investigated for each assessment. To examine the instruments' validity, the Mathematical Knowledge for Teaching (MKT) instrument, a measure of the quality of classroom teaching, and student learning outcomes will be used. The project also will explore automated scoring of teachers' open-ended responses to video clips and compare it to score reliability obtained by human coders.
