Educational Testing Service and Mursion developed eight performance-based tasks for preservice elementary teachers. This specific project includes materials for one mathematics task, Fractions Between, where teachers lead discussions with student avatars about a novel strategy for finding fractions. The dataset contains scenario details, student work, and training materials for teacher educators.
Use Cases
- Analyzing teacher facilitation strategies based on the described discussion focus on strengths and weaknesses of a mathematical strategy.
- Developing training modules for teacher educators based on the included sample videos and simulation specialist materials.
- Studying pedagogical discourse in mathematics based on the scenario of a teacher-led discussion with fifth-grade student avatars.
Strengths
- Materials are part of a four-year project developed and validated by Educational Testing Service and Mursion.
- Includes resources for multiple stakeholders: pre-service teachers, teacher educators, and simulation specialists.
- Files are provided in multiple formats to encourage adaptation and ensure correct rendering of images and math notations.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
Provenance
