It has been shown that active learning strategies are effective in teaching complex STEM concepts. In this study, we developed and implemented a laboratory experiment for teaching the concepts of Boolean logic gates, molecular beacon probes, molecular computing, DNA logic gates, microRNA, and molecular diagnosis of hepatocellular carcinoma, which…

Describes a computer program used in an experiment in which the partial molal volumes of sodium chloride solutions are calculated as a function of concentration from densities measured with a pycnometer. The complete program listing (also available from the author on disk) and a sample run are included. (JN)

Describes a one-year program in which students are given lectures on instrumentation topics, acquire experience participating in campus and community laboratories, and complete individual projects to receive the master's degree. Indicates a high ability of attacking laboratory problems in students' achievement. (CC)

Describes the use of a microcomputer in studying a model experiment (Brownian particles colliding with thermal particles). A flow chart and program for the experiment are provided. Suggests that this experiment may foster a deepened understanding through mutual dialog between the student and computer. (SK)

Reports on a study which investigated the effects of having students analyze circuits in the laboratory compared with troubleshooting from homework problems. Results indicated that laboratory experiences provide a richer learning experience than lecture and homework alone. (TW)
