Physics Educators as Designers of Simulation using Easy Java Simulation (Ejs)

Research Digest
This is an early articulation of a teacher-designer stance. The value is that teachers can build models around the exact conceptual bottlenecks they see in class.
Use It Tomorrow
Use it to introduce EJS as a design environment rather than a repository of finished applets.
Pedagogical Move
Ask teachers to articulate the misconception first; the model design should respond to that learning need.
Student Agency
Frame the task so students work like young scientists: they choose or justify the variable to test, make a prediction, collect evidence, defend a claim, and decide how to improve the model or investigation.
Discussion Prompts
- What evidence does the model, video, or activity make visible?
- Which variable should students change first, and what should they keep constant?
- What claim can students make from the evidence, and what limitation should they acknowledge?
Reveal suggested answers
- Evidence: The design task makes student misconceptions, model assumptions, parameter choices, and feedback features visible to the teacher-designer.
- Variable: Change the representation or control that targets the misconception first; keep the core physics scenario and learning objective fixed.
- Claim: Teachers can claim that a simulation is useful when it helps students confront a specific misconception, while acknowledging that design choices shape what students notice.
