The S4 Changing Matter Elementary Science Task is part of the GO Discuss project developed by Educational Testing Service and Mursion. It includes materials for a simulated classroom task where pre-service elementary teachers facilitate a discussion on whether mixing substances creates new matter. The dataset was last updated on October 20, 2025.
Use Cases
- Training pre-service teachers on facilitating science discussions based on simulated classroom scenarios.
- Developing formative assessment rubrics for teacher performance based on the task's learning goals and student work.
- Analyzing teacher discourse patterns based on the provided discussion scenario and student claims.
- Creating adapted training materials for educator preparation programs based on the included Word and PDF documents.
Strengths
- Materials are part of a four-year research project developed and validated by Educational Testing Service and Mursion.
- Includes eight performance-based tasks across mathematics and science, with four specifically in science.
- Provides task-specific resources including sample videos and simulation specialist training materials.
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.
