This paper introduces a hardware and software independent model for producing educational computer simulation environments. The model, which is based on the results of 32 studies of educational computer simulations program production, implies that educational computer simulation environments are specified, constructed, tested, implemented, and…

Baroma (Balance of Rotating Machinery), the Web-based educational engineering interactive software for teaching/learning combines didactical and software ergonomical approaches. The software in tutorial form simulates a problem using Visual Interactive Simulation in graphic display, and animation is brought about through graphical user interface…

Computer simulations are one promising tool for supporting learning at all levels--from elementary school to workplace learning. Learning through simulations, either by creating simulations or by exploring existing ones, helps learners develop a deeper understanding of the concepts being simulated. Learning about simulations is also important…

Presents a multimedia component kit for digital electronics authoring and learning. Components available on the Internet facilitate sharing and reuse of educational software and provide authoring support. Emphasis is put on the implementation of a number of components based on simulation and animation that provide a high level of interactivity and…

The design of "Probability Explorer" was inspired by: lack of research-based elementary probability software; constructivist principles for designing computer microworlds; and research on children's probabilistic reasoning. Discussion includes the inspirational and theoretical basis for design; conceptualizing the "Probability Explorer"…

Learner-centered software design (LCSD) guides the design of tasks, tools, and interfaces in order to support the unique needs of learners: growth, diversity and motivation. This paper presents a framework for LCSD and describes a case study of its application to the ScienceWare Model-It, a learner-centered tool to support scientific modeling and…

Describes the establishment of a library of computer images of histological preparations and the use of this library for computer-assisted instruction. Images from various organ systems along with line diagrams are stored on a central file server which can be accessed from remote terminals. The Fabric of Life program allows testing on each image…

This paper establishes the roots of computers and automated teaching in the field of psychology and describes Dr. S. L. Pressey's presentation of the teaching machine; B. F. Skinner's teaching machine; Meyer's steps in composing a program for the automated teaching machine; IBM's beginning research on automated courses and the development of the…

Computers, because of their computational speed and multi-representational capabilities, are particularly well-suited to the implementation of dynamic models. This paper reviews research conducted on the use of computer-based models in precollege science classrooms. Topics addressed include Investigations of Running Simulations, Investigations of…

After an introductory overview of innovations in the use of computers in education, nine papers focus on the following aspects of computer use: (1) the computer in the curriculum; (2) factors influencing the introduction and integration of computers in education; and (3) research aspects, including needs for research. (SLD)

This paper considers the technological aspects of learning environment analysis in the instructional development process. Characteristics of a technology-based learning environment are discussed, and old and new models of technology and learning are examined. The connection between technology and cognition is addressed, and the importance of…

Researchers have claimed that while educational computer software does not necessarily improve students' academic performance, it does provide for students a more interesting and motivational environment for learning. It naturally fits in the context of students' learning since it can deliver nonstop actions, realistic sounds and vivid colors to…

A software tool called 3D-LAB has been developed for learning and teaching three-dimensional geometry. With this microworld, educators and students can display three dimensional solid objects, rotate them, modify them, open them up, draw points and segments, and measure lengths, areas, volumes, and angles. The major characteristics of this tool…

The reopening of a middle school in San Diego, California, provided a testing ground for a unique collaborative effort between the school faculty, a university department, and Apple Computer Corporation. The desire to infuse technology and cultural awareness across the curriculum led to the development of an interactive "microworld" game…

This paper presents a model for designing computer-based simulation environments within a constructivist framework for the K-12 school setting. The following primary criteria for the development of simulations are proposed: (1) the problem needs to be authentic; (2) the cognitive demand in learning should be authentic; (3) scaffolding supports a…
