Design an exit ticket, interpret synthetic responses and plan targeted feedback with a follow-up check.
A fictional lesson teaches the difference between percentage points and relative percent change. An exit ticket asks what happened when a rate rose from 20% to 30%. Five synthetic responses include two fully correct answers, two saying 10% relative increase and one giving only 50% without explaining the point change.
| Response | Answer | Diagnostic category |
|---|---|---|
| A | 10 points and 50% relative | complete |
| B | 10% relative | denominator confusion |
| C | 10 points and 50% relative | complete |
| D | 50% only | incomplete explanation |
| E | 10% relative | denominator confusion |
An assessment should reveal the skill the lesson intends to build. If the objective includes explaining a denominator, a final number alone is insufficient evidence. State the success criterion and decide how the response will guide the next teaching step. The exercise uses synthetic responses only.
Write the objective and a two-part exit ticket.
Exit-ticket design
Record your result and evidence here or in a separate file.
The ticket asks for both point change and relative change with reasoning.
Add an explanation prompt when a number alone could be guessed.
A codebook connects response patterns with possible learning needs. Do not infer a learner’s motivation or ability from one answer. Use cautious labels such as denominator confusion and incomplete explanation. Define what evidence would distinguish a slip from a conceptual misunderstanding.
Code all five responses and write a rule for each category.
Response codebook
Record your result and evidence here or in a separate file.
The counts are 2 complete, 2 denominator-confused and 1 incomplete.
Describe the answer pattern rather than labeling the learner.
Feedback should address the specific gap and lead to another attempt. For denominator confusion, show the two different calculations and ask the learner to name the baseline. For an incomplete answer, prompt the missing comparison rather than reteaching every concept. Keep the response proportionate to the evidence.
Write feedback for each non-complete category.
Feedback plan
Record your result and evidence here or in a separate file.
Each message includes a next action linked to the observed gap.
Replace good effort with a useful prompt or explanation.
A follow-up should use new numbers while testing the same distinction. Repeating the exact item may measure recall of feedback rather than understanding. Plan how the new evidence will change the teaching decision. This path does not invent a post-feedback improvement rate.
Create a 40% to 50% follow-up item and its explanation.
Follow-up assessment
Record your result and evidence here or in a separate file.
The answer is 10 percentage points and 25% relative increase.
Change the baseline while preserving the concept being assessed.
A formative record connects evidence, feedback and the next lesson move. State which learners would receive a brief group explanation and which need a focused prompt, without pretending the synthetic group is a real class. Keep the decision revisable when new evidence appears.
Write a one-page teaching response and review template.
Assessment-to-action record
Record your result and evidence here or in a separate file.
The record does not claim learning gains without a follow-up result.
Leave post-feedback outcomes pending until observed.
Deliver the objective, exit ticket, codebook, synthetic response analysis, targeted feedback and follow-up item. Explain what new evidence would cause you to change the next lesson.
Response patterns are not treated as fixed learner traits and no unmeasured learning gain is claimed.
| Criterion | Points | Evidence |
|---|---|---|
| Evidence and correctness | 30 | Calculations, source use and results match the supplied case; limitations are honest. |
| Required artifacts | 30 | All five stage outputs and the capstone handoff are present and inspectable. |
| Reasoning and decisions | 20 | Choices, assumptions, alternatives and the case-specific critical condition are explained. |
| Reproducibility | 10 | A reviewer can follow the stated steps and distinguish expected from observed results. |
| Clear communication | 10 | Labels, units, structure and evidence references make the work easy to review. |
Score at least 80/100, supply every required artifact, and satisfy the path-specific critical condition. Rework missing evidence before marking complete.
From 20% to 30%, the difference is 10 percentage points and the relative increase is (30−20)/20 = 50%. In the follow-up from 40% to 50%, the point change stays 10 while the relative increase becomes 25%.
This is an assessment-design exercise, not an administered test or an evaluation of real students.
