Presents a study that introduces data logging using portable computers as part of an investigative approach to science. Working with control and experimental classes of 14- and 16-year-olds, results suggest that data logging can have an impact on graphing skills at age 14 which is not necessarily repeatable at age 16. (Author/AIM)

Describes a study conducted in undergraduate science classes in Singapore using computer modeling and simulation. Reports that the use of computer models and simulations proved to be valuable in explaining many aspects of science. Students reported that three-dimensional images helped them in their understanding. Contains 22 references.…

Explains the use of the 3-dimensional analytic geometry method to find values for a field geology problem. Gives a description of the mathematical theory for this method which can be applied to data obtained by drilling as well as open surfaces, and a computer program. (RT)

Contends that elementary principals must be computer literate to be effective instructional leaders. Points out that principals should be familiar with computer hardware, software, computer assisted instruction, and micro-based administrative operations. (ML)

Reports on a process which allows active study of mutating the characteristics of a population of organisms. States that the program, written in C, should run on a MS/DOS system with 640K; CGA is required for graphics output. Describes implementation procedures and two examples using the program. (RT)

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Describes the use of simulation to introduce the bootstrapping technique of creating confidence intervals for the mean, median, and variance. These bootstrap confidence intervals are compared to the traditional confidence intervals for the purpose of analyzing accuracy of the technique. A Minitab program to produce confidence intervals is…

Surveys the present status of science instructional software in the United States. Describes project efforts at the University of Pittsburgh on the development of intelligent tutoring systems (ITS). Explains the major components and provides microworld examples of ITS. Includes the software evaluation instrument and summarizes the evaluation…

Described are examples of classroom exercises that use interactive graphics software for personal computers to enhance the teaching of statistical concepts by allowing students to generate multiple examples, make conjectures, and verify their findings about the concept. The transfer of this interactive tool to other subject areas is suggested.…

Examines the relationship of microcomputer simulation graphics and alphanumeric modes of data presentation to ninth-grade biology students' science process skills and conceptual understanding of selected science topics (N=64). Concludes that use of microcomputers and appropriate software can result in significant learning and understanding of…

Discusses uses of the microcomputer in elementary mathematics education. Included are: (1) drill; (2) practice; (3) problem solving; and (4) games. (YP)

Examines the interaction between mode of computer assisted instruction and cognitive style on the understanding of concept relationships and mastery of factual information. Finds learners are more effective when matched to the appropriate mode of computer assisted instruction. (MVL)

Examines the use of spreadsheets for solving equations by the method of iterations. The combination of the spreadsheets and graphical representation is shown to be appropriate both for teaching and learning the method of iterations and for investigating properties of equations. (Author)

Examines the use of the computer to approximate the value of the definite integral normally calculated by mathematical means. Presents four examples using BASIC programs to approximate single and double integrals by numerical integration and the Monte Carlo method. Programs are provided. (MDH)

Described is a method of evaluating student chemistry laboratory reports using electronic reporting from locally developed macros. Examples of the input template, the grade report template, and input and grading programs are given. Results of a survey of students and teachers evaluating the program are reported. (MDH)
