Discussed are balloons and electroscopes, understanding cosmic rays, cosmic ray paths, isotopes and cosmic-ray travel, sources of cosmic rays, and accelerating cosmic rays. Some of the history of the discovery and study of cosmic rays is presented. (CW)

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

Described is a membrane experiment that provides students with experience in fundamental engineering skills such as mass balances, modeling, and using the computer as a research tool. Included are the experimental design, theory, method of solution, sample calculations, and conclusions. (KR)

Describes the author's 10 years of experiences with the Student Exam Review Committee (SERC) that he formulated in response to intrinsic difficulties with examinations generated for large sections of college science courses. Discusses the selection of committee members, preexam input by the whole class, the committee's exam review process, and…

Presents an overview of an evaluation of projects developed to improve students' quantitative reasoning skills and understanding of technology. (ZWH)

An activity that introduces students to the concepts of independent assortment of alleles during meiosis and gametogenesis, the richness of the variation that occurs as a result of allele recombination, and the unique phenotypes of offspring. Reproducible handouts with the directions and model chromosomes are provided. (KR)

The results of actual student participation, with organized group discussions, which show that laboratory teaching remains the premiere mechanism for teaching and learning organ-system physiology are discussed. Laboratories using a pithed frog, a turtle heart, an anesthetized rabbit, and noninvasive recordings from students during exercise are…

Provides short synopsis of biochemical education leading to a master of science degree at the University of Gulbarga, India. Discusses admissions policy, teaching methods, seminar availability, evaluation schemes, student input, current research areas and projects, and liaison with other institutions and industry. (JJK)

Use of in-class writing assignments in a college chemistry course, intended to help students form and express new concepts, was also found to increase students' sense of participation and feeling of control over learning and to help the instructor assess learning and further instructional needs. Some resistance was also discovered. (MSE)

Indiana University college teacher discusses undergraduate science education and effective teaching in introductory courses. The method recommended by educator Arnold Arons trades passive lecture for hands-on learning and Socratic dialogue. Indiana University began a successful research program which brought Arons' method to large-enrollment…

Discussed is how modern physics is usually approached via the photoelectric effect and how this can lead to a physically wrong picture of light. The importance of using the quantum theory developed after 1920 to explain the properties of light is discussed. (KR)

Listed are 75 computer software programs which are available for use in teaching physiology at the high school and college level. Included is a brief description of each and an address for obtaining additional information. (CW)

The idealistic picture of the professor as teacher and researcher is examined. Each section of this article presents an argument against the overemphasis on research that is widespread at universities. (KR)
