This paper examines the effect of using a systems thinking approach in existing secondary school curricula to teach content-specific knowledge as well as general problem solving skills, and the effect of using STELLA (Structural Thinking Experimental Learning Laboratory with Animation), a simulation-modeling software program, as a tool by which to…

This is the second of two reports on the first year activities and results of the Systems Thinking and Curriculum Innovation Project (STACI), a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking,…

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…

To explore the potential of computer controlled videodiscs for simulating undergraduate science laboratory instruction, the Annenberg/CPB (Corporation for Public Broadcasting) Project funded the University of Nebraska to create and field test six videodisc laboratory experiments, two each in biology, chemistry, and physics. The six discs were…

This study explores a learning model which suggests that a concept is acquired first through manipulation of concrete objects followed by transformation of the concrete objects into semi-concrete representations, followed by internalization of the concept through abstract representations. Microcomputer simulations of manipulative activities were…

Discussion of problems encountered in educational software development in Japan is the second of a two-part series on evaluation of Japanese microcomputer-based software. Problems associated with content, learner attitude, and graphics presentation are described, and future challenges in simulation and integrating courseware with other teaching…

Reports on a study which was designed to determine if computer assisted instruction (CAI) can be used effectively in biochemical education. Results indicate that CAI in the drill and practice mode and computer simulations had no detrimental effect on the students' academic achievement and the students would like more CAI. (TW)

Surveys current research on learning and memory and associated brain functions. Suggests several models of olfactory recognition and memory. Explains several computer models being evaluated and lists possible flaws. Differentiates between noise and chaos in brain functions. Describes a challenge to the theory of chaos called adaptive resonance…

Examines effective ways of practicing reading that facilitate the development of efficient reading skills in beginners. Indicates that increases in reading efficiency depend largely on the amount of independent, computer-aided practice with speech feedback, a method that seems promising as a means of improving reading skills in beginners.

Reviews two studies whose results indicate that students who share computers develop better work skills and social attitudes. One study, using eighth graders and a computer simulation, measured performance on worksheets and final exams. The second study used language learning via computer-assisted instruction to compare results on achievement…

Ten papers focus on applications in specific curriculum areas, modelling and simulation, and computer managed learning. Projects described include voice support for the visually handicapped, distance education, and industrial training, as well as teaching applied mathematics, several facets of engineering, zoology, and, with videodisc, observation…

This study investigated the verbal interactions of fifth grade students within groups when using simulation and word processing software. Students were grouped according to ability, and conversations were analyzed, which found the largest proportion of student talk was cognitively oriented, predominantly in directing and reporting language; group…

Describes the Teaching Decisions Simulation, a program that allows participants to make decisions regarding lesson plan activities and student and teacher spatial arrangement or interactions. Postlesson feedback includes variables such as completion time and performance measures. Experienced teachers exhibited more deliberation in completing the…

Discusses the use of intelligent tutoring systems as opposed to traditional on-the-job training for training operators of complex dynamic systems and describes the computer architecture for a system for operators of a NASA (National Aeronautics and Space Administration) satellite control system. An experimental evaluation with college students is…

Two methods of assessing student learning of a hands-on instructional unit are compared. One method involves manipulation of concrete materials, and the other method involves manipulation of icons on a computer to solve an electric circuits problem. Sixth-grade students in an inquiry-based science program completed both assignments. (LZ)
