Recommendations
High Priority
- Add 10-15 more questions for underserved concept clusters — particularly advanced cross-cutting topics (e.g., error propagation, spectroscopy interpretation, inquiry-based lab design questions)
- Add 3-5 questions specifically about laboratory technique — the AP Exam includes experimental design questions, but FAQ coverage of lab skills is light
- Add questions about MicroSim usage — students unfamiliar with interactive tools would benefit from a "How do I use the [specific MicroSim]?" entry for the most complex simulations
Medium Priority
- Add coverage of buffers in more detail — the Henderson-Hasselbalch equation is covered, but questions about buffer capacity and choosing the right buffer system for given constraints are missing
- Add questions about spectroscopy (IR, UV-Vis interpretation) — Beer-Lambert Law is covered but spectral interpretation is not
- Add questions connecting lab error to percent error calculation — the accuracy/precision entry covers concepts, but a worked calculation example is missing
Low Priority
- Consider adding a "What tools do I need?" FAQ entry listing the only tools needed (web browser, calculator, pencil, paper)
- Add a "How do I cite this textbook?" entry for students doing research papers
Suggested Additional Questions
- "How do I design an experiment to determine reaction order?" (Common Challenges)
- "What laboratory safety rules are most important for chemistry?" (Getting Started)
- "How do I calculate percent yield and why does it differ from theoretical yield?" (Technical Detail)
