Historical and current educational perspectives are epistemologically challenging to weave together. The contributors brought together in this book have risen to that challenge and, in the process, have produced a detailed and thorough account of the issues and processes at play. Science, Mathematics, and Technology (SMT) education is recognised…

Despite the rigorous debate around the purposes of higher education and the associated concept of graduate attributes, science education at the tertiary level has remained largely impervious to engaging with these ideas. This may be due to the emphasis on the knowledge base of the hard science as opposed to the emphasis on the knower in the…

Discusses a misconception about the cycloid that asserts the final point on the path of shortest time in the "Brachistochrone" problem is at the lowest point on the cycloid. Uses a BASIC program for Newton's method to determine the correct least-time cycloid. (MDH)

Reports results of study examining the effect of inservice education program on middle school science teachers attitudes toward teaching and on teaching behaviors. A nonrandomized control group pretest/posttest design was used with a sample of 44 teachers. Results showed no significant attitude difference between the treatment groups. However,…

The planning and organization of problem-solving workshops for teachers are discussed. Suggestions for activities and anecdotes of teacher participation at workshops are provided. (CW)

Reports a study investigating the utility of 52 items, selected from a readily available item pool developed for instructional purposes, when the items are used to measure critical thinking abilities of biology students. The items had reasonably good internal consistency reliability and good concurrent validity. (PR)

Uses the problem of determining when a car and truck traveling at the same speed will collide after the truck has applied its brakes to illustrate the need to consider boundary conditions when solving problems in elementary mechanics. (MDH)

Reports on specific problem-solving difficulties of 240 chemistry teachers from 5 Nigerian states who volunteered to take part in 3 written tests and an interview. Describes the contrasts between successful and unsuccessful problem solvers, and discusses the pedagogical and psychological implications of the findings. (16 references) (JJK)

Presents a motion problem that students in a college physics class are asked to solve and later asked to continue to analyze until they have stopped learning from the problem or the problem itself is finished. (MDH)

Presents a mathematical problem that, when examined and generalized, develops the relationships between power and efficiency in energy transfer. Offers four examples of simple electrical and mechanical systems to illustrate the principle that maximum power occurs at 50 percent efficiency. (MDH)

Presents a new method to teach the subject of evaporators which is both simple enough to use in the classroom and accurate and flexible enough to be used as a design tool in practice. Gives an example using a triple evaporator series. Analyzes the effect of this method. (CW)

Described are the use of two different tests designed to test for selected inquiry skills. Procedures, tests used, and results in several different countries are presented. Implications for classroom instruction are discussed. (CW)

Presents a problem to determine conditions under which two identical masses, constrained to move along two perpendicular wires, would collide when positioned on the wires and released with no initial velocity. Offers a solution that utilizes the position of the center of mass and a computer simulation of the phenomenon. (MDH)

Educational programs in the clinical laboratory sciences are responsible for producing professionals who can function in new environments. In addition, it is the responsibility of all individuals in the profession, regardless of professional role/function to assume the role of educator to prepare students in a way that is appropriate and useful to…

Presents an experiment to investigate centripetal force and acceleration that utilizes an airplane suspended on a string from a spring balance. Investigates the possibility that lift on the wings of the airplane accounts for the differences between calculated tension and measured tension on the string. (MDH)
