Different programs have been developed for the simulation of physics experiments by using TI-57 programmable calculators. Two of these programs, describing the simulation of a successive radioactive decay and the random motion of a gas molecule, are presented. (Author/SK)

An investigation of the relationships among student attributes, styles of teaching, and outcomes in a BSCS-based secondary school biology course is described. Two teaching styles, individual and small group teaching and whole group teaching, were investigated as were student attributes including general ability, personality characteristics, and…

Describes a systematic investigation of the understanding of velocity by students in introductory physics courses. Data were obtained using the individual demonstration interview, similar to the clinical interview. Results are reported for success of different populations in comparing velocities for two simultaneous motions. Implications for…

Presents an experiment for inorganic, organic, or physical chemistry students utilizing acid-base titrimetry to study the stoichiometric of a solid state reaction. Time involved ranges from one to three, three-hour lab periods. (Author/SA)

Biology teachers can provide lessons for students to help them plan the future wisely. Three natural laws are emphasized as imperative to understanding how to plan wisely for restoring a balance in nature. (SA)

Various ways in which teachers can discover how much learning is going on in their classrooms are described. Distinctions are made between "on-task" time in which learning occurs and "elapsed time" or off-task time. (SA)

Ideas are given for including fungi in classroom activities for high school biology students. A discussion on the science of taxonomy leads into a discussion on the position of fungi in the five kingdom classification scheme of organisms. Suggestions are given for observing their growth and development. (SA)

Presents a method for teaching high school students about evolution at the genus level as well as at higher taxons. Activities for a laboratory project and laboratory techniques are described. (SA)

Described are the results of research in chemical education carried out at the University of California, Berkeley. Individualized instructional materials to teach major concepts of stoichiometry to unprepared students were developed and validated. (BT)

Outlines an approach for instruction in a physical chemistry laboratory which combines traditional and project-like experiments. An outline of laboratory experiments and examples of project-like experiments are included. (BT)

An experiment is presented on the formulation of a negative photoresist. It is intended for use as a fifteen minute classroom demonstration for undergraduate general chemistry students. (SA)

The author describes activities he uses with secondary school science students to learn about their reasoning. (Author/SA)

Reports an attempt by Purdue University to establish a committee to investigate teaching abilities of the graduate teaching associates in the School of Science and to establish and implement recommendations. Their model is described with the intent of making it useful to other colleges and universities. (SA)

Suggests that a variety of approaches to teaching science should be used so that concept development occurs. Sensory experiences alone may not be enough. It is suggested that the current trend towards "hands-on" learning may represent a reaction to overemphasis on the verbal and abstract in science. (Author/SA)

A collection of six papers presented at Queen Elizabeth College of University of London in February, 1979. Techniques presented on role of computer models and data bases, tapes/booklets, games and models, and audio tutorials as an alternative to practical teaching, television and videotapes, and computer graphics.
