Procedures and programs for Web-based homework administration were developed and tested. The special feature of the protocol is the option of a "second chance". When a student gives a wrong answer in the weekly homework assignment, a second version of the same question is posed to that student within 48 hours. Both the original and the second versions of the homework are Web-based and automatically graded. More than 90% of the students used the second chance at least once during the semester. More than 60% used this feature for every homework assignment. The second-chance option motivates students to study the …

Describes how a core group of faculty built the Lucid Chemistry Web Site over four years and how students in large first and second year chemistry courses have started to use it (slowly at first, and now to near 100 percent participation in some classes). The facility has been developed for use by key administrative units (Testing and Evaluation, Computer Services). Now coming to the Lucid Chemistry Web Site are roughly one‐half of the chemistry department instructors and tenure‐track faculty. Asks whether the task of teaching needs more “builders”. Argues that more administrative involvement is needed with material creation and …

Multiple choice homework, including feedback on each incorrect answer, is administered over the Web using an in‐house program. The large enrollments in lower division courses hinder the use of homework without the aid of a computer for grading, recording, and reporting. The current system permits faculty to create assignments using only a word processor, which allows the facile inclusion of symbols, pictures, and other non‐textual information. This is particularly important in science classes, where such material is a major part of any assignment. The system includes security measures, and reports scores back to instructors in a form which can be …
