Course map

Automate a safe repeated workflow
Communicate uncertainty honestly
Interpret a comparison without claiming causation
Compare search strategies
Evaluate errors across groups
Run a pilot and decide what changes

Read or watch the example, try three questions, make the project and reflect. Roughly half the session is for creating and explaining. Take breaks and adapt reading support.

All examples are fictional. Use approved tools and adult support where indicated. Project checkboxes are self-review, not automatic assessment or certification.

Review levels

With support: completes with prompts. Independently: meets the criteria and explains a choice. Transfer: applies the skill in a new setting with evidence.

GRADE 10 · EXPERIENCE 1 · DIGITAL CONFIDENCE

Automate a safe repeated workflow

Plan a bounded automation with a preview and recovery path. · About 50 minutes

Answers and reasons

A. Stop and resolve the collision
A collision could overwrite or confuse files. Resolve it before acting.
B. Bound the scope and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Scope → Preview → Validate → Recover
The example follows: Scope → Preview → Validate → Recover. Explain what each step does.

Project evidence to review

Write pseudocode and a preview table for renaming six fictional files. Do not run it on real school folders.

Bound the scope
Detect name collisions
Explain recovery

Teaching guidance

Evaluate the plan and tests; no bulk file mutation is required.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Add a test for an empty folder.

GRADE 10 · EXPERIENCE 2 · CREATE AND COMMUNICATE

Communicate uncertainty honestly

Distinguish a measured result, estimate and unsupported guess. · About 50 minutes

Answers and reasons

C. These three trials took 18-22 minutes
It reports the actual observed range.
A. Separate observations from estimate and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Measure → Summarise → Qualify → Recommend
The example follows: Measure → Summarise → Qualify → Recommend. Explain what each step does.

Project evidence to review

Write a brief planning note using the three times. Label the estimate and supporting observations.

Separate observations from estimate
Keep uncertainty visible
Make an actionable recommendation

Teaching guidance

Avoid inventing probabilities from only three observations.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Rewrite the note for a younger reader.

GRADE 10 · EXPERIENCE 3 · DATA AND DECISIONS

Interpret a comparison without claiming causation

Describe an observed difference and possible confounding factors. · About 50 minutes

Answers and reasons

A. 20
Use the given numbers: the answer is 20. Explain your counting or calculation.
C. Use the supplied values accurately and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Read → Represent → Calculate → Interpret
The example follows: Read → Represent → Calculate → Interpret. Explain what each step does.

Project evidence to review

Report both completion rates and two alternative explanations. Propose a fairer comparison.

Use the supplied values accurately
Show a calculation or count with its meaning
State a fair comparison or limitation

Teaching guidance

Ask the learner to show intermediate work. Use fictional data; no real pupil records are needed.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Distinguish a 20 percentage-point difference from a relative percentage increase.

GRADE 10 · EXPERIENCE 4 · COMPUTATIONAL THINKING

Compare search strategies

Explain when binary search is applicable. · About 50 minutes

Answers and reasons

C. Sorted input
Ordering lets a comparison safely exclude part of the list.
B. State the sorted-input requirement and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Set → Middle → Narrow → Find
The example follows: Set → Middle → Narrow → Find. Explain what each step does.

Project evidence to review

Trace linear and binary search for 14. Count comparisons and state the midpoint rule.

State the sorted-input requirement
Trace the same target fairly
Count comparisons consistently

Teaching guidance

Trace before testing. These are learning models and pseudocode, not instructions to run arbitrary downloaded code.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Test a missing target and a one-item list.

GRADE 10 · EXPERIENCE 5 · RESPONSIBLE TECHNOLOGY

Evaluate errors across groups

Look beyond an overall accuracy figure. · About 50 minutes

Answers and reasons

C. 40%
4 / 10 × 100 = 40%.
A. Calculate rates correctly and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Count → Calculate → Compare → Investigate
The example follows: Count → Calculate → Compare → Investigate. Explain what each step does.

Project evidence to review

Write an evaluation note for the fictional results. Include group rates, sample-size limits and a question to investigate.

Calculate rates correctly
Compare relevant error types
Avoid calling a tiny test conclusive

Teaching guidance

Use fictional groups A and B; do not infer sensitive traits about real students.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Explain how false positives and false negatives could have different effects.

GRADE 10 · EXPERIENCE 6 · DESIGN AND LIFE SKILLS

Run a pilot and decide what changes

Use a small trial to learn before expanding. · About 50 minutes

Answers and reasons

A. To notice an unintended problem
A benefit metric alone may hide a cost or failure.
C. Set a bounded scope and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Bound → Measure → Observe → Decide
The example follows: Bound → Measure → Observe → Decide. Explain what each step does.

Project evidence to review

Plan a fictional book-swap pilot with two measures, a stop condition and a review date.

Set a bounded scope
Include unintended effects
Connect the next decision to evidence

Teaching guidance

Do not run a real event or collect pupil data as part of this exercise.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

Propose a change if participation rises but misplaced books also increase.
