Discusses aspects of the syntax and semantics of film, and presents a scenario for the use of film by intelligent computer assisted instruction (ICAI) systems. An outline of a representation language for educational films on videodisc is presented, and an appendix provides conceptual graphs that explain notations used in examples. (Author/LRW)

Described is the use of two types of physical sensors, a motion sensor, and a light gate, which enable the microcomputer to be used as a measuring instrument for practical experiments on motion. (KR)

This summary reports the highlights of a survey on microcomputer usage in institutions of higher education which was sponsored in part by EDUCOM. Software issues are emphasized, including assistance in evaluation, integrating software into the curriculum, and policy and procedures concerning illegal access and duplication. (LRW)

Studies the effects of varying levels of interactivity on the learning rate of 98 high school students using four increasingly interactive versions of computer-based interactive video instruction. Students are grouped by ability levels and results are compared for recall rate, instructional time, and acquisition rate. Twenty-two references are…

Two questions about the effects of microcomputer-based laboratory (MBL) activities on graphing skills were addressed in this study: (1) the extent to which activities help students link their concrete experiences with motion with graphic representations of these experiences; and (2) the degree of importance of the real-time aspect of the MBL in…

During the first 12 weeks of an applied calculus course, two classes of college students studied calculus concepts using graphical and symbol-manipulation computer programs to perform routine manipulations. Three weeks were spent on skill development. Students showed better understanding of concepts and performed almost as well on routine skills.…

Summarizes six research studies relating to computers in education. The research areas include the use of computer-generated graphs in critical evaluation and in learning distance and velocity concepts, sex differences in graphing skills, student evaluation of courseware, career paths of women with technological education, and characteristics of…

Computer graphing makes it easier for students and teachers to create and manipulate graphs. Scale issues are nearly unavoidable in the computer context. In interviews and protocol analysis with six students from grade 8, and 12 students from grades 11 and 12, it became apparent that some aspects of scale are clearly understood very early while…

Research indicates that the educational effectiveness of Microcomputer-Based Laboratories (MBL) may be due to the real time nature of the experience. This article describes a study where kinesthetic feedback was completely removed by giving students only visual replications of a motion situation. If simultaneity of perception is the important…

The Agency for Instructional Television (AIT) has established a consortium of 42 state, provincial, and local educational agencies to develop computer/video materials in problem-solving, prepare inservice materials, and define and conduct policy studies. The purpose of this study, which focuses on the last task, was two-fold: (1) to identify…

This report summarizes the work of a two-year project which focused primarily on the problems that students have with algebra in general, and graphs in particular. The first of two major sections in the document deals with the use of computer software to assist in the teaching of graphing. It concludes that thoughtful design and use of graphing…

Describes a computerized system which presents objective test items to students, and upon question completion, provides immediate feedback with correct answers and explanations. Use of the system by pharmacology students and an analysis of end-of-year examination results are presented. (Author/MBR)

This study investigated effects of microcomputer placement in three resource rooms for learning disabled elementary school children to explore student and teacher behavior changes and teacher microcomputer use. Results indicate no significant impact on student and teacher behavior. Teacher use varied, with teachers assigning different priority…

This aptitude-treatment interaction (ATI) study was designed to clarify the relationship between the aptitude variable spatial visualization and two modes of presentation of linear absolute-value inequalities. The modes of presentation include computer-enhanced instruction (CEI) and traditional. (Author/KR)

The Triple Representation Model of problem solving is presented. The use of microcomputers in this problem-solving environment is discussed, and examples are provided. The integration of this method into the mathematics curriculum is described. (CW)
