GO Discuss Mystery Powder Task: Simulated Classroom Materials for Teacher Training

Materials for one elementary science task called Mystery Powder from the GO Discuss project. The four-year project developed performance-based tasks in a simulated classroom environment to improve preservice elementary teachers' ability to orchestrate discussions. Educational Testing Service and Mursion created eight tasks, four in science and four in mathematics, validated for formative assessment.

Use Cases

• Training preservice teachers in facilitating goal-oriented science discussions based on the simulated classroom scenario.
• Analyzing teacher performance in leading consensus-building discussions based on the provided student work and background information.
• Developing formative assessment tools for educator preparation programs based on the validated task structure.

Strengths

• Materials are part of a four-year research project developed and validated by Educational Testing Service and Mursion.
• Task includes specific resources for teacher educators, such as 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.

Provenance
