The application of chemistry to the justice system is presented. The role of the forensic chemist, historical development of forensic laboratories, and tools of the criminalists are also discussed. (HM)

A description of the commercially produced Harris Data Memory is presented. Operation instructions, memory capabilities, data storage, and applications are included. Usefulness of the instrument to instruction in all of the sciences is considered. (SA)

Discussed are the advantages and disadvantages of two different philosophical approaches, academic or traditional versus experimental, to the laboratory instruction of undergraduate physics students. The defects, failures, and limitations of each approach are detailed. (BT)

Describes a study correlating observational test question scores and lab notebook evaluations. Results indicate that, while there is no correlation between those two factors, there are problems with evaluating notebooks objectively. (MA)

Reports on a series of studies related to seeking a more effective role for laboratory experiences in science instruction. The study addressed the status of laboratory-based instruction in chemistry at the beginning college level. This study should be of value in the continual search to seek effective means of reforming beginning college-level…

Describes a Japanese process-oriented approach called KAIZEN for improving the quality of existing teaching laboratories. It provides relevant quality measurements and indicates how quality can be improved. Use of process criteria sidesteps the difficulty of defining quality for laboratory experiments and allows separation of student assessment…

Presents results of a controlled experiment comparing the conceptual mechanics learning gains as measured by the Force Concept Inventory (FCI) between two laboratory groups. One group completed cookbook labs while the other completed Interactive-Engagement (IE) labs in RealTime Physics. Suggests that laboratory activities should engage students in…

Introduces students to dissection, which is an important part of scientific discovery. Students not only gain an understanding of the anatomy of a squid, but also develop a sense of responsibility and respect for the animal that they are using as a learning tool. (Author/SOE)

Discusses how traditional lab exercises can be converted into investigative exercises. Describes an exercise on seed germination that has students design their own experiments based on their initial results. Involves students in the scientific process and allows them to experience the joys and disappointments of experimental work. (JRH)

Describes a course that uses student-designed laboratory experiments for a one-semester, junior-level physiology course. Discusses advantages and pitfalls of using this methodology. (Author/KHR)

Compares the effects of three different teaching methods: (1) traditional instruction through listening to a lecture, reading, and participating in discussion; (2) instruction with teacher-constructed self-teaching resources; and (3) instruction with student-constructed self-teaching resources. Determines their effectiveness and the time required…

Develops a simple tree-ring laboratory to demonstrate the basics of dendrochronology. Provides two upper-level laboratory exercises primarily intended to demonstrate the specific dendrochronology subdisciplines of dendroclimatology and dendroecology. Suggests using the exercises separately or in unison as part of a multidisciplinary capstone…

Presents lab exercises in which students use the microscope to study cells. Describes these activities as allowing students to work independently and become more proficient at microscope use. Students also gain a deeper understanding of the more invisible world of science. (Author/KHR)

Described is a project designed to determine the kinds and types of science laboratories located in and around Yolo County, California. Summarized are some of the sites visited by the investigator and some of the impressions of those facilities. (CW)

Court rulings have established three basic responsibilities school systems must meet in science programs: (1) inform students about the hazards they might encounter in a science class; (2) provide a safe learning environment and properly maintained equipment; and (3) ensure adequate supervision. Outlines a four-point school safety plan. (MLF)
