Educational Testing Service and Mursion developed eight performance-based tasks for preservice elementary teachers. This specific project includes materials for one elementary science task called Conservation of Matter, where students investigate whether matter is conserved when making lemonade. The materials were deposited by Jamie Mikeska via QDR Harvested Dataverse and last updated on October 20, 2025.
Use Cases
- Analyze teacher facilitation strategies based on the simulated classroom discussion scenario.
- Develop training modules for teacher educators based on the included sample videos and resources.
- Study disciplinary argumentation in science education based on the task's focus on student claims and evidence.
- Validate performance-based assessment tools based on the project's goal of building a validity basis.
Strengths
- Includes materials for a complete simulated classroom task, including scenario details, student work, and teacher resources.
- Part of a larger validated project (GO Discuss) that developed eight tasks across science and mathematics.
- Provides resources for multiple stakeholders, including pre-service teachers, teacher educators, and simulation specialists.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
