Develops a compact minicell design in which the measured voltage is close to the desired emf. Notes student's observations for several cells are within 0.02V of the expected values. Presents numerous reasons for using miniware and semimicro qualitative analysis. Full experimental writeup is available from the authors. (MVL)

An interactive videodisk entitled "Motion: A Visual Database" developed at the Cambridgeshire College of Arts and Technology (CCAT) is described. Three of its 194 real experiments are discussed. (YP)

Described is an introductory laboratory course designed to enhance basic skills required of biology majors. Discusses materials and their development, manual design, and student and instructor's roles. Outlines procedures and examples of writing, reading, and mathematics activities. (RT)

Reports on students' attitudes toward reading science during an experimental study that investigated ways to increase comprehension of technical material. Describes the procedure, results, conclusions, applications, and implication. (RT)

Described is a reliable and predictable laboratory experiment which represents the result of an integrated approach to design with an emphasis on teaching. Notes the flat-celled rig has logged over 100 hours service in 2 years without any problems. (MVL)

Presented is a photoelectric colorimeter which can be assembled by the student. Reports that it can do many of the same analyses as the SPEC 20 but at a greatly reduced cost using older technology. Presents several experiments to use with the colorimeter. (MVL)

Notes that as the student progresses through school, science experiences hold a less positive view. Used are teacher interviews and classroom observations conducted to determine possible explanations. Points out that schools need to help students realize how much science affects their everyday lives. (MVL)

Recounts a high school chemistry lab explosion while distilling alcohols. Proposes peroxide formation in older samples of alcohols as the cause. Lists commonly found laboratory alcohols and their peroxide concentrations. Discusses methodology for both detecting and removing peroxides. (MVL)

Discusses a method for teaching time pulsed NMR principals that are as simple and pictorial as possible. Uses xyz coordinate figures and presents theoretical explanations using a Fourier transformation spectrum. Assumes no previous knowledge of quantum mechanics for students. Usable for undergraduates. (MVL)

Describes an engineering course for graduate study in process control. Lists four major topics: interaction analysis, multiloop controller design, decoupling, and multivariable control strategies. Suggests a course outline and gives information about each topic. (MVL)

Describes the use of "CACHE IBM PC Lessons for Courses Other than Design and Control" as open-ended design oriented problems. Presents graphics from some of the software and discusses high-resolution graphics workstations. Concludes that computing tools are in line with design and control practice in chemical engineering. (MVL)

Discussion of the use of new technologies in science instruction focuses on the medium of CD ROM. Topics discussed include database retrieval; simulations and laboratory experiments; videodisks; hypertext; and software and interfaces for laboratory experiments. A list of math and science resources is provided. (LRW)

Describes a method for more effectively storing information on a videodisk to allow greater flexibility. Argues that in order to best use the limited capacity of a single sided video disk that shorter integrated units be used. Gives several examples. (MVL)

Discusses the need to develop more efficient information retrieval skills by the use of new technology. Lists four stages used in automating the media center. Describes North Carolina's pilot programs. Proposes benefits and looks at the media center's future. (MVL)

Describes case study that examined the processes and outcomes related to the development of knowledge bases by groups of seventh grade science students in Toronto who were studying classification of living organisms. Expert system shells are discussed, and cognitive and metacognitive skills used in the activity are examined. (23 references)…
