Compared the effectiveness of using guided-design or traditional approaches to study the energy problem in America. Examined to what extent students: (1) actually learned material; (2) perceived they learned the material; and (3) became more involved in discussing and considering solutions to energy problems. Includes course and guided-design…

This study found that students who experienced a field-oriented laboratory approach had higher affective scores (related to levels of importance, interest, and enjoyment associated with the learning experience) than students in a traditional laboratory setting. A description of the approaches used is included. (JN)

Compared the quality of preparation and attrition of students in a traditional remedial chemistry course with students in a remedial course having a personalized system of instruction (PSI), self-paced format. Although the PSI course suffered heavy attrition, PSI students did significantly better in later courses, which held up over time. (JN)

Many assert that the use of animals for dissections in the secondary and undergraduate class is unnecessary. This article describes a study conducted to compare the attitudes and achievement of students who use interactive methods instead of conventional dissection. (ZWH)

An evaluation study comparing a computer assisted learning-based project with three more conventional ones in an Open University course on evolution is reported. Special attention is paid to reasons why students chose to do different projects and the factors contributing to the variance in the marks awarded for their work. (Author/JN)

Reports on a study designed to determine the relative effectiveness of different instructional approaches on chemistry laboratory achievement. Investigated differences in achievement in spectrophotometry among college freshmen who received either traditional, learning cycle, or computer simulation instruction. Results indicated that students…
