Internet Problems Audio Help

The ChemPhys Internet Problems assignments are intended to provide students with opportunities to individually apply problem-solving strategies to current topics in order to better internalize the mathematical relationships and improve problem-solving skills. The emphasis on the problem sets is to provide students with individual practice.

Many ChemPhys students occasionally or regularly have difficulty getting started on a problem or simply get stuck once they have started. For such students, there is a need for help in order for them to sustain the individual application of problem-solving in Physics. The Audio Help section is intended to meet that need for individual help in order to get a student started or un-stuck. Each problem set is accompanied by a collection of audio files for strategically chosen problems. The audio files provide explanations, suggestions, hints, diagrams and at times animations for solving the problems. The ultimate goal is to help students become more confident of their problem-solving habits and more independent in their approach to problem sets. The links below lead to the Audio Help pages.
