Examined relationship between cognitive requirements of two chapters of a physics textbook for biology/pre-med students and their ability to use prerequisite reasoning skills required for its understanding. An average of 42 percent of students tested did not consistently use reasoning skills required to understand text concepts. Discusses tests…

Outlines methodology, demonstrations, and materials including: an inexpensive wave machine; speed of sound in carbon dioxide; diffraction grating method for measuring spectral line wavelength; linear electronic thermometer; analogy for bromine diffusion; direct reading refractice index meter; inexpensive integrated circuit spectrophotometer; and…

Discusses current uses of computers in United Kingdom schools, specifically in biology, chemistry, economics, geography, and physics classrooms. Suggests reasons why teachers are using computers and describes their application for simulations; construction, evaluation, and modification of models; and for academic games. (DS)

Different methods of teaching using the computer in a Computer-Assisted Instruction (CAI) system are discussed and illustrated with sample courseware in mathematics, physics, and elementary science. (DS)

Discussed is whether, and to what extent, science teachers critically and spontaneously attend to the logical structure of situations, and whether they need prompting, or completely fail to do so. The relationship between the results of this study and science teachers' pre- and in-service education is discussed. (Author/KR)

Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing. (CW)

Described is a mobile hands-on science program called "Light Works" that is brought directly into the classroom. The reasons for the implementation of "Light Works" into primary classrooms is discussed. The advantages and operation of this program are included. (KR)

Describes two applications of the microcomputer for laboratory exercises. Explores radioactive decay using the Batemen equations on a Macintosh computer. Provides examples and screen dumps of data. Investigates polymer configurations using a Monte Carlo simulation on an IBM personal computer. (MVL)

Describes methods for teaching mechanics. Concepts included are force, inertial frames, and rotation. Emphasizes how to feel or observe them. (YP)

Evaluates 5 courseware packages covering the topics of simple harmonic motion, 7 packages for wave motion, and 10 packages for sound. Discusses the price range, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each courseware. Selects several packages based on the criteria. (YP)

Described is the use of automated control using microcomputers. Covers the development of the microcontroller and describes advantages and characteristics of several brands of chips. Provides several recent applications of microcontrollers in laboratory automation. (MVL)

Discusses electron spin resonance, a form of magnetic resonance spectroscopy, used to study electronic structure of molecules with unpaired electrons. Studies benzosemiquinone radical anions which are long-lived and inexpensive. Uses a Project SERAPHIM computer program to perform a Huckel molecular orbital calculation. (MVL)

Offers several LOGO programs to study the behavior of simple nonlinear systems. Suggests that LOGO is an excellent tool for studying chaotic systems. Offers suggestions for different forms of LOGO. Builds upon programs presented in a previous article. (MVL)

Examines two instructional strategies, the traditional and learning cycle approaches, and compares them with regard to the variables of sequence, format, and necessity. Concludes that students exposed to the laboratory and discussion type had higher test scores than those in the lecture or reading groups. (Author/RT)

Discusses a teaching method using investigational skills for Nuffield A-level Physics including assessment technique, change of the assessment criteria, advice for choosing the topic, and future development. (YP)
