Follows the development of a course in nuclear and radiochemistry at Penn State. Lists specific nuclear science topics covered in the undergraduate level course. Describes audio-visual materials that have been developed for the course and includes a survey of students taking the course. (ML)

Describes a simple laboratory procedure for changing sodium carbonate into sodium chloride by adding concentrated HCl to cause the reaction and then evaporating the water. Claims a good stoichiometric yield can be obtained in one three-hour lab period. Suggests using fume hood for the reaction. (ML)

Recommends using iodide ions and peroxodisulfate ions for studying rate laws instead of the standard iodine clock for kinetic study. Presents the methodology and a discussion of the kinetics involved for a laboratory experiment for a high school or introductory college course. (ML)

Describes a biophysical chemistry experiment that introduces students to globular protein conformation and microcomputer analysis of initial rate data for the unfolding of proteins. Presents background, materials needed and methodology. Uses a visible spectrometer for analysis. Lists educational benefits derived from the experiment. (ML)

Describes experiences for engineering students to develop spatial awareness and reasoning capability. Describes geometric modeling, basic geometric concepts, operations, surface modeling, and conclusions. (YP)

A Dickinson College (Pennsylvania) introductory physics program abandons lectures in favor of activity-based, collaborative work enhanced by use of integrated computer tools. Contrary to expectation, it was found that some women did not respond positively to hands-on, collaborative instructional methods. (MSE)

A discussion of group dynamics in collaborative learning describes use of this approach in an experimental biology course. Three approaches to group dynamics are outlined (personality and learning style, cognitive style, and group life). Identified are variables that teachers either have little power to affect, can address in course design, or can…

Discussed is why one of the main concerns of scientists and educators should be making the public aware of the nature of science and its role in society. Presented are ways in which science can be communicated with and without the classroom. (KR)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)

Some important considerations for potential courseware authors to think about before they enter the authoring process are discussed. A description of the hardware requirements, an evaluation of 11 authoring tools based on quality and cost, and the conclusions are provided. (KR)

Selective illustrative examples of students' learning difficulties and misconceptions in first-year general and organic chemistry are presented in the students' terms, followed by strategies the author uses to overcome the difficulties. Suggests that student misconceptions in first-year chemistry are not interrelated logically and are not prone to…

Provides examples of how concept mapping can be used to help overcome misconceptions in college chemistry. (PR)

Described is a professional development program at Heriot-Watt University in Scotland. Discussed are the teaching of the relationship of civil engineering to society and ethics, issues about the style of this type of course, and summative evaluation. Recommendations are provided. (CW)
