Video Coding

To guide iterative refinement of our materials, both treatment and control teachers were videotaped throughout the year during their Algebra I lessons. Information is presented below about the coding schemes which our team developed in order to analyze the teacher videos.

General Fidelity Checklist

The general fidelity checklist was used to code videos for teachers in both the treatment and control conditions. Codes were designed to capture whether or not teachers used core instructional practices (e.g., teacher or students compared multiple strategies) which were emphasized in our implementation model. Coding was done at the lesson level.

Treatment Coding Scheme

This scheme was used to code treatment teacher videos. The codes target several additional features (beyond the core instructional practices deemed integral to the use of our materials) that were hypothesized to be instrumental to promoting learning. Coding was done at the lesson level.
