A programed, two-credit hour, experimental microbiology course for nonscience majors is described. (SA)

Catalysis is defined and discussed as the process relates to science history, chemical reactions, enzymes, industry, catalytic reactors, and catalyst preparation. (SA)

Presents a series of behavioral objectives for a 60 hour science unit designed to train laboratory technicians in safety, basic laboratory skills, laboratory service and fittings, and first aid. (SL)

Examines the benefits of the Z-shaped science lab classroom configuration as a means of learning enhancement. Each section of the classroom is illustrated and described. Also discusses construction and cost considerations. (GR)

Discusses the importance of laboratory safety in science classrooms. Urges middle school teachers to address class size in an effort to establish and maintain a safe working environment. Answers a teacher's question related to having newts and salamanders in the classroom. (SOE)

Describes portable scientific laboratories that allow students to go beyond the classroom to do field work. Presents examples of a curriculum that incorporates portable technology and discusses its advantages in inquiry-based science programs. Includes handheld probes and peripherals. (KHR)

Any overhead projector easily can be converted into a simple spectrometer by placing a piece of diffraction grating over the projecting lens. A detailed description of the apparatus and suggested spectroscopy experiments are included. Demonstrations can utilize solutions of cobalt chloride, potassium permanganate, potassium dichromate, or…

In this demonstration of the generation and combustion of acetylene, calcium carbide and water are allowed to react in a latex examination glove. Two student volunteers perform the demonstration with instructor guidance. This safe, popular demonstration, originally intended to illustrate the alkyne family of compounds, can be used with a variety…

Describes four models: The Authoring Cycle, a whole language approach that reflects the inquiry process; I-Search, an approach to research that uses the power of student interests; Cultural Celebration, using local heritage topics; and Science Lab Report, for the composition of a lab report. (LRW)

Describes a research and development project aiming to help develop secondary students' abilities to understand biotechnology/genetic engineering. Focuses on an exemplary true-to-life experiment, planned and executed by students in grade 8, that involves external experts and uses an industrial research laboratory for solving genuine questions.…

Describes a project involving the development, application, and evaluation of a virtual chemistry laboratory (VCL) that involves basic step-by-step laboratory procedures and simulates real laboratory activities. Presents the program in terms of tutorial, VCL, and evaluation, and a section that allows instructors to create their own tests. (KHR)

Discusses how engineers will be educated in the twenty-first century, including workstation, teaching methods, teaching materials, and the college system. Describes some of the obstacles, such as small numbers of applicants, aging professors, poor preparation at high school level, and costs. (YP)

Describes how student learning from a series of laboratory practicals was improved using small group methods and a structured learning cycle that encouraged reflection on group performance and investigative techniques. Discussion includes evaluation of learning benefits by means of written records, a questionnaire, observation, and the role of…

Investigated the relationships among gender, prior academic performance, beliefs, and student attitudes toward biology laboratory experiences of (n=294) 10th, 11th, and 12th graders. Gender, prior academic experience, and beliefs were significant predictors of attitudes. (24 references) (Author/MKR)

Surveys of (n=179) department chairs showed 47% of secondary science teachers did not use microcomputers during instruction, but 76% indicated microcomputers have had an impact on science laboratory activities in their school. Most frequent applications were simulations, graphing packages, and probes for collecting laboratory data. (17 references)…
