Science Task Prescreen
Task Title: Investigating the Invisible: Gravity vs. Electrostatics
Grade: High School
Date: 2024-04-24
SEP: Using Mathematics and Computational Thinking
DCI: PS2.B: Types of Interactions
CCC: Patterns
Task Purpose: To engage students in using mathematical representations (Newton’s Law of Gravitation and Coulomb’s Law) via a simulation to describe and predict gravitational and electrostatic forces.
Instructions
- Before you begin: Complete the task as a student would. Then, consider any support materials provided to teachers or students, such as contextual information about the task and answer keys/rubrics.
- Prescreen: Answer the following high-level questions to identify any major red flags (🚩) in your task. If you find one or more red flags, consider the purpose of the task and the evidence gathered to determine whether the task warrants a deeper dive.
Prescreen Questionnaire
| Question | Yes | No |
|---|---|---|
| 1. Is there a phenomenon or problem driving the task? | [x] | [ ] 🚩 |
| 2. Can the majority of the task be answered without using information provided by the task scenario? | [ ] 🚩 | [x] |
| 3. Can significant portions of the task be answered successfully by using rote knowledge (e.g., definitions, prescriptive or memorized procedure)? | [ ] 🚩 | [x] |
| 4. Does the majority of the task require students to use reasoning to successfully complete the task? | [x] | [ ] 🚩 |
| 5. Does the task require students to use some understanding of disciplinary core ideas to successfully complete the task? | [x] | [ ] 🚩 |
| 6. Do students have to use at least one science and engineering practice to successfully complete the task? | [x] | [ ] 🚩 |
| 7. Are the dimensions assessed separately in the majority of the task? | [ ] 🚩 | [x] |
| 8. Is the task coherent and comprehensible from the student perspective? | [x] | [ ] 🚩 |
Recommendation
Based on your assessment needs and the task purpose recorded above, make a recommendation about this task moving forward (choose one):
- [x] Warrants further review.
- [ ] Should not be used.
Summary
Summarize your evidence and reasoning:
The task effectively anchors student learning in an observable, everyday phenomenon (magnets and static balloons vs. Earth’s gravity). The task requires students to generate data via the simulation to understand the relationship between distance, mass, charge, and force magnitude. Rather than assessing definitions, students use computational thinking and mathematical representations (SEP) to discern patterns (CCC) in the forces (DCI). Thus, it tightly integrates all three dimensions without red flags.
