Improving Teachers' Comprehension of Curriculum-Based Measurement Progress-Monitoring Graphs

The authors examined three instructional approaches for improving teachers' curriculum-based measurement (CBM) graph comprehension, each differing in the extent to which reading the data, interpreting the data, and linking the data to instruction were emphasized. Participants were 164 elementary school teachers who were randomly assigned to one of three CBM instructional approaches or a control condition. Instruction was delivered via videos. Prior to and after receiving instruction, teachers completed a CBM graph-comprehension task. They also evaluated the instructional videos. Teachers in the three instructional groups improved more in CBM graph comprehension than control teachers. Improvements were seen primarily in interpreting and linking the data to instruction, two important but difficult aspects of CBM graph comprehension. Differences between the instructional groups were found for interpreting the data. Teachers evaluated the videos positively. Results indicate that teachers' CBM graph comprehension can be improved via video instruction. Implications for teaching teachers to implement CBM are discussed.
