Describes two computer simulations of the predator-prey interaction in which students explore theories and mathematical equations involved in this biological process. The programs (for Apple II), designed for college level ecology, may be used in lecture/demonstrations or as a basis for laboratory assignments. A list of student objectives is…

Two new packages designed to aid students in typical undergraduate biochemistry courses are described. These packages deal with alcoholic fermentation and the reversal of glycolysis and the reactions of the citric cycle. (MP)

Investigated the overall effectiveness of and use of animation/graphics in "Introduction to Organic Chemistry" computer programs on student achievement and attitudes (n=approximately 400). Results indicate that although materials were effective animation sequences, they did not have an effect on student test scores. (JN)

Two copy-protected chemistry simulations (for Apple II) are described. The first demonstrates Hess' law of heat reaction. The second illustrates how heat of vaporization can be used to determine an unknown liquid and shows how to find thermodynamic parameters in an equilibrium reaction. Both are self-instructing and use high-resolution graphics.…

Describes an interactive computer game (for Apple II) designed to challenge students' problem-solving skills. The game is appropriate for science/mathematics classes from high school to college (particularly in logical problem-solving units). Includes game design/operation and list of characteristics of scientific research (as applied to general…

Ten computer simulations for the Apple II are described. Subject areas of programs include: population dynamics, plant competition, enzyme kinetics, evolution and natural selection, genetic mapping, ammonia synthesis, reaction kinetics, wave interference/diffraction, satellite orbits, and particle scattering.
