In science education, there is a need to evaluate the behavior of dynamic systems. Representing and explaining processes through educational models or simulations enables students to perform activities where it is easier to understand these processes and discover the essential properties of a system. Performing modeling or simulation activities…

Describes a conceptual scheme that will help elementary school children understand the occupations and types of work he learns about in school. (SB)

Discusses educational applications of computer simulation and model building for grades K to 8, with emphasis on the usefulness of the computer simulation language, micro-DYNAMO, for programing and understanding the models which help to explain social and natural phenomena. A new textbook for junior-senior high school students is noted. (EAO)

The booklet describes the approach to career education for hearing impaired students developed by the Kendall Demonstration Elementary School (KDES) in the District of Columbia. The KDES model is described in terms of project direction and the seven model components: planning, staff development, program development, curriculum development,…

A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity, and it is a viable alternative. Differences between the models are reviewed. (Author/RD)

Reviews evidence that children use diverse cognitive strategies; discusses the adaptive value of using diverse strategies; describes models of strategy choice based on rational calculations; and presents an overview of the distributions of associations model of children's strategy choice. (RH)

A hypothetical country is devised using geographical terms charts. Students act as advisors in predicting future development of the land and community growth by using present relationships between physical environment and land utilization in actual regions as a base model. (Author/MB)

This paper describes a paradigm for tutorial systems capable of automatically providing feedback and hints in a game environment. The paradigm is illustrated by a tutoring system for the PLATO game "How the West Was Won." The system uses a computer-based "Expert" player to evaluate a student's moves and construct a "differential model" of the…

Six environmental education simulation games are presented in this manual, developed by Project SESAME G (Susquehanna ESEA Synergetic Activities for Maximal-involvement via Education Games). The simulations are models of social situations which provide an opportunity for social interaction in the classroom, maximize student involvement, and change…

The XX IDEA annual conference has been focused and reflected on different ways and means of meeting various kinds of methodological challenges, new technologies and multi-media developments, newly emerging partnerships and collaboration between emerging sectors on one hand and between the institutions functioning with similar objectives and…

Data are used from the individualized math component of an operating educational system to validate the basic assumptions underlying EDSIM 1, a computer simulation model that traces the interaction of three probabilistic elements in an educational program and produces synthetic output regarding this interaction in terms of student time in the…

This report describes the first of three stages in a study in the domain of problem solving: the definition and explication of schema knowledge. One objective of this research is to understand how schema knowledge is acquired and used in the chosen domain. The focus is on ways in which instruction influences the development of specific knowledge…

Proposes a theory of cognitive processes in doing and learning place value arithmetic. Discusses a computer model that simulates the learning of multicolumn subtraction under one-on-one tutoring to measure the relative difficulty of two methods of subtraction. The model predicts that regrouping is more difficult to learn than an alternative…

The essays collected in this volume are concerned with the field of computer-based intelligent instruction. The papers are organized into four groups that address the following topics: particular theoretical approaches (3 titles); the development and improvement of tools and environments (3 titles); the power of well-engineered implementations and…
