- Answer input
- Correct and incorrect branches
- Score
- Question progression
- End summary and restart
Guided Class Project
Guided Class ProjectQuiz of Questionable Knowledge
Answer useful questions while the host insists that at least one distractor involves moon cheese.
Visible system / hidden curriculum
Build something clear enough to test.
What students learn
- True/false conditions
- Text comparison
- Score updates
- Question state
- Feedback
- Testing alternate inputs
What students need
- Browser
- Scratch editor
- Keyboard
- Student-written questions
Students should write original questions and avoid collecting personal information in quiz answers.
Suggested build order
Decisions and checkpoints, not a wall of copied blocks.
Students may use different artwork and implementation details. The shared structure keeps the concept teachable.
- 01
Write three questions
Task: Choose clear questions with verifiable answers.
Build and test this part before adding the next system.
- Checkpoint
- Each question has one stated expected answer.
- Likely mistake
- Using opinion as a scored fact.
- 02
Ask and capture input
Task: Use the answer input for one question at a time.
Build and test this part before adding the next system.
- Checkpoint
- The current answer is inspectable.
- Likely mistake
- Checking an old answer variable.
- 03
Create two branches
Task: Give distinct feedback for correct and incorrect responses.
Build and test this part before adding the next system.
- Checkpoint
- Both branches can be demonstrated.
- Likely mistake
- An else is attached to the wrong condition.
- 04
Track score and question
Task: Update score once and advance the current question.
Build and test this part before adding the next system.
- Checkpoint
- One answer cannot score twice.
- Likely mistake
- Several scripts change score.
- 05
Finish and restart
Task: Show a summary, then reset score and question state.
Build and test this part before adding the next system.
- Checkpoint
- A new quiz begins cleanly.
- Likely mistake
- Question state remains at the end.
Test it
Try the edges, not only the easy success.
- Does capitalization matter?
- Can one answer score twice?
- Does every wrong answer advance?
- Can the quiz skip a question?
- Does restart reset score and question state?
Common mistakes
Read the clues before changing code.
- Comparing numbers and text incorrectly.
- Score changes in several scripts.
- Feedback does not match the branch.
- The next question begins before feedback is readable.
Improve it
Preserve the core system while changing the project.
- Accept equivalent answers.
- Add categories.
- Choose questions randomly without repeats.
- Explain the final score by topic.
Challenge levels
Choose meaningful difficulty.
Builder
Create five reliable questions.
Inventor
Accept two forms of an answer and explain why.
Boss Level
Build non-repeating randomized question selection.
Show-teacher checkpoint
Demonstrate the working decisions.
- Original questions
- Correct and incorrect paths
- Reliable score
- Question progression
- End summary
- One repaired condition bug
