Discusses the use of computerized databases in instructional settings. Provides examples of how such instructional databases could be accessed directly by students. Lists some commercially available databases, distinguishing between their type, computer compatability, price, grade level, and their general searching abilities. (TW)

Reviews software that focuses on writing skills for children aged 2 to 15. Includes information on public domain and commercial programs on learning the alphabet, basic penmanship, sentence structure, and writing book reports and essays. Provides ordering information on the suggested programs. Explains how parents can help. (ML)

Discusses the use of a computer program designed to solve the mathematical model associated with soil nutrient uptake by plant roots and to predict the nutrient uptake. Describes a user-friendly personal computer version of this program. (TW)

Background information, data input, data analysis, and advantages of using this method with this software are discussed. A flowchart of the event-trapping program structure and a printout of the program are included. (CW)

Studies the simple dynamical system of the pendulum and the chaotic behavior that occurs when the pendulum is both damped and driven. Provides an algorithm and BASIC program for the numerical solution to the differential equations encountered in the discussion. (MDH)

Described is a mathematics resource laboratory where students use a variety of computer materials to enhance, reinforce, and broaden their concepts of first- and second-year algebra and geometry. Included are sample laboratory sheets and the answers. (KR)

Describes the application of expert systems to provide computer-assisted instruction support to students to facilitate their learning of both fundamental and advanced statistical concepts. Provides examples of both a modular system and an integrated system which utilize VP-Expert, an expert system development shell. (14 references) (Author)

Presented is an activity in which probability and percents are taught using a basketball computer simulation. Computer programs that replicate the free-throw accuracy of college and professional stars and allow students to compete with those stars are included. (KR)

Presented is a series of eight hands-on exercises using Apple II computer graphics to investigate the following characteristics of periodic functions: period, amplitude, horizontal shift, and vertical shift. Detailed teacher instructions and the accompanying computer program are included. (MDH)

Described is a simple electronic interface that can receive signals from up to four analog sensors and four event detectors and save the data on disk. Schematic diagrams, construction details, sample temperature plot and weather station logging programs, and a parts list are included. (KR)

Examined are the three regular tessellations and derived semiregular tessellations whose regular polygons meet at common vertices. Included are BASIC computer program listings that explore the various combinations of regular polygons that can form regular or semiregular tessellations. (JJK)

The assumptions common to all capture-recapture models for estimating population size are reviewed. A simulation using either a playing board, counters, and dice or computers is described. Classroom implications of using the board game are discussed. (KR)

This publication, one of a series of instructional manuals for industrial arts education, is designed to assist teachers as they plan and implement new courses to create environments that integrate classroom learning with students' real life experiences. The material is organized in seven instructional units. Each unit consists of objectives, key…

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Describes a heat capacity experiment designed to provide an interactive environment between the student, the experiment, and the computer. Discusses computer software that has been developed so that the entire interaction can be coordinated from the computer keyboard. (TW)
