Presents AlphAI, an educational software resource that lets K-12 and university students train educational robots with supervised or reinforcement learning while visualizing neural networks, KNN, and Q-learning internals.
Problem
Teaching AI and machine learning concepts to K-12 students is often too abstract, while existing tools only teach using AI and do not reveal how the algorithms work inside.
Approach
Combine robot-based supervised and reinforcement learning with real-time visualization of AI internals (sensor digitization, neural network activity, 1D/2D decision graphs, Q-learning steps) and optional student-written Python AI code, so that students can "open the black box" of AI.
Key results
- In an elementary school study (138 students, grades 3-5, six classes), AI knowledge correct answers rose from 39% pre-test to 65% post-test on one question.
- Metacognitive knowledge agreement on perseverance rose from 65% to 81% after the workshop.
- A university 'Initiation to AI' course has been given for three years to about 250 students.
Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Complete the AlphAI workshop | AlphAI workshop for elementary school students · Elementary school grades 3–5 | correct answers: 39% to 65% | Helped |
| Complete the AlphAI workshop | AlphAI workshop for elementary school students · Elementary school grades 3–5 | agreement with perseverance statement: 65% to 81% | Helped |
Limitations
- Mapping of activities to educational standards remains to be done.
- Impact assessment is limited to a single elementary school study and a university course without reported controlled comparison.
- Software is commercial (Learning Robots), and a web-based version is still under development.
