This study compares overall laboratory averages and individual test scores along with a student survey to determine the effects of using virtual microscopy in place of optical microscopes in a large undergraduate human anatomy course. T-tests revealed that the first two laboratory examinations (of four) and the overall laboratory averages were…

Kinetics constitutes a core topic in both the lecture and laboratory components of lower- level chemistry courses. While textbook examples can ignore issues of time, temperature and safety, the laboratory can not. Reactions must occur slowly enough to be detected by students, occur rapidly enough for data collection in the few hours assigned to a…

This article presents the development of a carbon dioxide fountain. The advantages of the carbon dioxide fountain are that it is odorless and uses consumer chemicals. This experiment also is a nice visual experiment that allows students to see evidence of a gaseous reagent being consumed when a pressure sensor is available. (Contains 3 figures.)…

A series of activities involving comparing weights of objects directly, using non-standard units, using standard units, using simple scales, and using complex scales are described. (SD)

How the criticism of a teacher led to the improvement of his experimental psychology course and a symposium on teaching experimental psychology. (Author/DE)

Indicates that specific laboratory standards for handling chemical carcinogens should become law in the near future. Small colleges and universities may have financial trouble in complying with laboratory safety standards investigated by the Occupational Safety and Health Administration. (GS)

Discusses the operation of the Health and Safety at Work etc. Act 1974 in relation to British universities. (MLH)

Discusses types of laboratory waste materials and methods for their safe disposal. (MLH)

Describes the hazards of using living materials in the science laboratory and outlines safety procedures that are particularly applicable to schools. Explains hazards to both mental and physical health and examines the latter in terms of fundamental and contingent factors. (Author/GS)

Describes the general features of three schemes used by teachers to assess their students' manipulative, observational, interpretational, and planning abilities and their attitude toward laboratory work. The three schemes were open-ended, intermediate, and check-list modes. A comparison of grades derived from these modes is presented. (GS)

A mathematics laboratory with commercial and teacher-made materials, a workshop, and a discussion room were established. An extension course taught how to use the instructional aids and accompanying behavioral objectives and activity cards. Active use of the lab is increasing. The teachers' enthusiasm has spread to the students. (KM)

Criticizes studies of egocentric development in children using cutaneous perception procedures. Also questions study contribution to the understanding of the development of decentering. (Author/SDH)
