Pro Tips
- *Start with an intent table template listing user phrases, bot replies, and transitions, then have students test each row with sample conversations before coding.
- *Assign rotating team roles like conversation designer, coder, data wrangler, and tester so mixed-ability groups contribute meaningfully and learn collaboration.
- *Use a small, standards-aligned rubric that scores flow accuracy, clarity, and usability, and require one improvement cycle after user testing with classmates.
- *Run mini demo days with timeboxed challenges such as add one data source or accessibility feature, and let peers vote using criteria to promote healthy competition.
- *Protect privacy by banning personal data in inputs, reviewing logs together for safety and bias, and requiring keyboard navigation and alt text in every project.
