Pro Tips
- *Use a rubric that rewards evidence quality, cross-curricular links, clear visuals, and accessibility, then share it on day one so students design with criteria in mind.
- *Seed projects with small real datasets from sensors or labs, then have students replace the sample data with their own so everyone reaches an interactive win quickly.
- *Run sprint cycles with weekly demo days, 45 to 60 minute build sessions, and a two-sentence update requirement that logs progress directly on the portfolio.
- *Require accessibility basics for every site, including alt text, keyboard focus styles, readable color contrast, and a print stylesheet for judges and parents.
- *Differentiate by offering three build tracks in the same class, visual edits for beginners, code peek for intermediates, and full code for advanced students, plus peer mentors at each level.
