Described is the computer simulation program "PH." The program consists of three different laboratory investigations dealing with the pH specificity of enzymes. The purpose of the program is to enable tenth- to twelfth-grade students to determine a possible explanation for pH specificity in an experimental, but mathematical, fashion.…

Three computer programs are presented that allow the high school student to explore and understand the physical forces involved in orbital flight at a greater depth than is usually possible. For each program, introductory material is given including the physics and mathematics involved. This is followed by the computer program in BASIC language.…

Described is the population growth computer model "POP." This program is designed to allow a student with little mathematical background to explore various simple mathematical models of population growth. Student exercises revolve around the growth of a gypsy-moth population. Three variations of population modeling are included in POP:…

Students investigate several aspects of the War of 1812, especially those which pertain to Lake Erie and Ohio, in this unit. The first activity is a simulation of various battles and maneuvers. In parts B and C, students use information from the simulation and from documents of the era to explain the war's causes and outcomes. A student's guide…

This guide is intended to provide stimuli for discussion and review of ecological principles and their relevance to daily human existence. The illustrations, purposefully detailed and complex, are intended to provide a basis for in-depth discussion. The bulletin is intended to supplement classroom materials and also to serve non-classroom…

Described is the computer model "MALAR" which deals with malaria and its eradication. A computer program allows the tenth- to twelfth-grade student to attempt to control a malaria epidemic. This simulation provides a context within which to study the biological, economic, social, political, and ecological aspects of a classic world…

Described is the use of the computer model "BUFLO." BUFLO is a simulation which allows students to study the historical and biological reasons for the extinction of the buffalo. BUFLO simulates the natural life cycle of the buffalo and allows the student to manipulate harvesting policies to reach certain goals outlined in the student handbook.…

Describes seven styles of software designed to improve mathematics and science learning: (1) microworlds, (2) educational games, (3) microcomputer-based instrumentation, (4) databases, (5) tools, (6) languages, and (7) simulations. A list of recommended science and mathematics software is presented with suggestions for further areas for software…

The student module for this unit on dilution problems includes objectives, prerequisites, pretest, discussion, and 10 problem sets. Included in the teacher's guide are…

Presented are the teacher's guide and student manual for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student manual for this solution stoichiometry unit includes objectives, prerequisites, pretest, discussion, and 20 problem sets. Included in the teacher's guide…

Presented are instructions for the use of "TAG," a model for estimating animal population in a given area. The computer program asks the student to estimate the number of bass in a simulated farm pond using the technique of tagging and recovery. The objective of the simulation is to teach principles for estimating animal populations when they…

Presented are instructions for the use of "RATS," a model simulating the dynamics of a rat population in either a city or an apartment house. The student controls the conditions of growth and sets the points at which the computer program prints reports. The rat population is controlled by variables including garbage levels selected for the site,…

Provided are details for a game designed to help secondary school or college students understand the types of problems encountered in applied hydrobiology and the financial and time constraints involved in their solution. (PB)

Presented are the teacher's guide and student materials for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student module for this introductory unit on chemical equilibrium includes objectives, prerequisites, pretest, instructions for executing the computer program,…
