✦ Synopsis

Industrial hygiene laboratory for distance education. Part 2: Course evaluation

A college-level laboratory course titled ``Industrial Hygiene Virtual Laboratory'' (IHVL) was created in CD-ROM format. In the beta version tested and reported here, the laboratory contained 11 modules, including calibrations, particulate sampling, sampling for gases and vapors, ventilation and indoor air quality, noise, bioaerosols, and thermal stressors. The efficacy of this course was classroom tested among 10 upperclassmen enrolled in a course on the topical material taught by the CD-ROM. Students were divided into two matched groups, which alternately performed laboratory sessions either on the CD-ROM or in the traditional college teaching laboratory. Differences in average scores between the groups were not statistically different (p 0:05). Pedagogical conclusions are that the electronic laboratory sessions were not better at teaching the subject matter, but that the CD-ROM laboratory is at least as effective as attendance in traditional teaching laboratory. Implications for teaching this or other traditionally laboratory-based courses are discussed.
