We present an active way to use a computer animation in secondary molecular genetics class. For this purpose we developed an activity booklet that helps students to work interactively with a computer animation which deals with abstract concepts and processes in molecular biology. The achievements of the experimental group were compared with those…

Describes a method to produce 35mm color slides directly from the display screen of a computer terminal using techniques and equipment available to most teachers and researchers. Discusses the hardware and software needed, procedures, some of the problems encountered, and the potential uses of this method. (CW)

Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)

To determine if different levels of graphic presentation affected understanding, 131 middle school science students with high and low spatial ability were shown programs teaching concepts of molecular diffusion with no graphics, static graphics, or animated graphics. Students with low spatial ability benefited from animated presentations. Spatial…

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Reviewed are three computer software packages including "Martin Luther King, Jr.: Instant Replay of History,""Weeds to Trees," and "The New Print Shop, School Edition." Discussed are hardware requirements, costs, grade levels, availability, emphasis, strengths, and weaknesses. (CW)

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

Discusses some of the attributes of effective tutorial software programs. Describes four science programs that focus on the physical and earth sciences, and highlights some of their features that are proposed as features of high-quality educational software. (TW)

Reviewed are four computer software packages: "Minerals Data Base"; "Canvas 2.1," a graphics program for producing technical illustrations; "Glossary of Geology Speller"; and "PCUSA," which produces maps and statistical diagrams of the United States. Hardware requirements, functions, cost and availability…

Describes three software packages: (1) "MacMendeleev"--database/graphic display for chemistry, grades 10-12, Macintosh; (2) "Geometry One: Foundations"--geometry tutorial, grades 7-12, IBM; (3) "Mathematics Exploration Toolkit"--algebra and calculus tutorial, grades 8-12, IBM. (MVL)

To increase the connection between educational research and educational practice, a process called "curriculum reformulation" was used to incorporate recent advances in research on learning and instruction into science classroom experiences. The cognitive demands of a thermodynamics curriculum were successively refined while maintaining…

Presents a computer program which prints out a calendar corresponding to any year A.D. and states the objectives for such a program. Shows an example of a sample run. (RT)
