Because advanced students had difficulty in interpreting cleavage patterns obtained by gel electrophoresis related to rapid sequencing techniques for DNA and RNA, several formats were developed to aid in understanding this topic. Formats included print, print plus scrambled print, interactive computer-based instruction, and high-resolution…

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)

Describes a program which allows students to identify and characterize several kinetic inhibitory mechanisms. Uses the generic model of reversible inhibition of a monosubstrate enzyme but can be easily modified to run other models such as bisubstrate enzymes. Uses MS-DOS BASIC. (MVL)

This project developed a new kind of computer simulation and explored its impact on teaching and learning in introductory biology. The aims of the project were to: (1) develop a flexible simulation environment that would permit students to design, build, and test realistic simulations; (2) support student experimentation with intelligent tutoring…

The purpose of this study was to examine the effects of different levels of visual elaborations and practice on application learning of adults in a computer-based science lesson. A total of 141 university students participated in an introductory lesson covering Newtonian mechanics. Three levels of visual elaboration (static graphic, animated…

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…

Research was undertaken to investigate various methods of presentation of a computer based science simulation as it related to student content knowledge of the simulation concepts. Three treatment groups of sixth grade students were used in the study: (1) two students per computer interacting with the simulation; (2) a total class presentation of…

A conference attended by 40 "students" and 20 "teachers" was held to explore the state of the art in computer-assisted instruction (CAI). The school was held in a remote Italian resort, but direct connections with computers in Italy and the United States were made to provide opportunities for demonstrations of existing systems.…

Describes a computer-assisted oil exploration and production game for students involved in a short course in petroleum geology. Outlines the game and its procedures, and provides sample structure maps generated by the computer in the course of playing the game. (TW)

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)

Describes 10 computer programs (available from authors), including graphics display of molecular structure, cyclohexane stereo chemistry, calculation of thermodynamics properties of chemical reactions, and others. Also described graphical display of chemical interactive programs using a programmable calculator and discusses distribution of…

Tested were all-verbal or verbal-pictorial presentations followed by either pictorial practice or a control task with 96 undergraduates; results favored pictorial presentation with review. Also tested were effectiveness of pictorial review tasks to a read-twice control with 50 different undergraduates. Pictorial review facilitated performance and…

Outlines techniques used in the context of a sixth grade science class to teach database structure and search strategies for science using the AppleWorks program. Provides templates and questions for class and element databases. (Author/YP)

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)
