Peer Instruction Vote Shift
Compare peer-instruction concept votes before and after discussion.
Description
Before-and-after concept votes compare aggregate correctness around peer discussion.
Before-and-after concept votes compare aggregate correctness around peer discussion. Percentage-point change describes the difference on one cohort denominator.1
Compare peer-instruction concept votes before and after discussion.
When to use Peer Instruction Vote Shift
Use this tool to compare peer-instruction concept votes before and after discussion.
Prepare the lesson timeline, roster, observations or assessment labels requested. Use consistent units and exact identifiers, then choose comparison criteria appropriate to the activity.
How to use Peer Instruction Vote Shift and understand its results
- Prepare the lesson timeline, roster, observations or assessment labels requested. Use consistent units and exact identifiers, then choose comparison criteria appropriate to the activity.
- Enter initialCorrect, postDiscussionCorrect, participants using the field table and calculation rules, then run the tool.
- Read initialPercent, postPercent, percentagePointGain. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| initialCorrect | Initial correct | number | Required |
| postDiscussionCorrect | Post discussion correct | number | Required |
| participants | Participants | number | Required |
Enter positive safe-integer participants and integer correct counts within that total. Return initial/post percentages and signed percentage-point change.
gainPoints=100(postCorrect−initialCorrect)/participants Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| initialPercent | Initial percent | number |
| postPercent | Post percent | number |
| percentagePointGain | Percentage point gain | number |

}Limitations and assumptions
No individual vote transitions, attendance changes or causal learning effect are inferred. A negative change is a valid outcome.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
