From dynamic spreadsheets through "microworlds" to virtual reality, the convenience and, in many instances, the seemingly intrinsic appeal of simulated environments exist in some tension alongside concerns regarding the relationship of the simulated to the "real" and the possible consequences for human thought, learning, and behavior. A selection…

"Bohr's Atomic Model" is a small interactive multimedia program that introduces the viewer to a simplified model of the atom. This interactive simulation lets students build an atom using an atomic construction set. The underlying design methodology for "Bohr's Atomic Model" is model-centered instruction, which means the central model of the…

Describes and evaluates the design and development of an interactive multimedia simulation package for management education called Business Simulation which combines the concepts of case study methods with business simulation games. It is designed to provide students with skills-based training in human resources management, particularly…

Describes a pilot study aimed at exploring the possibility of introducing simulation-based homework into junior high school ninth grade science classes studying electric circuits. Analyzes students' views in relation to their prior computer experience and their achievement, and discusses results from questionnaires and interviews that show…

Describes "Wyzt's Playground", a fourth grade math multimedia title that emulates and simulates the real-life scenario of building a playground and supports the instruction of mathematics and measures proficiency in five NCTM (National Council of Teachers of Mathematics) standards. Explains the multimedia production process and the…

Biology knowledge and understanding is important not only for the conversion of the loftiest dreams into reality for a better life of individuals but also for preparing secondary pupils for such fields as agriculture, medicine, biotechnology, and genetic engineering. But a recent study has revealed that many aspects of school science (biology…

This study aims to investigate the effects of a virtual reality (VR)-based learning environment on learners with different learning styles. The findings of the aptitude-by-treatment interaction study have shown that learners benefit most from the VR (guided exploration) mode, irrespective of their learning styles. This shows that the VR-based…

Laboratory exercises, field observations and field trips are a fundamental part of many earth science and environmental science courses. Field observations and field trips can be constrained because of distance, time, expense, scale, safety, or complexity of real-world environments. Our objectives were to develop an environmental virtual field…

This paper examines children's and adults' attitudes to virtual representations of museum objects. Drawing on empirical research data gained from two web-based digital learning environments. The paper explores the characteristics of on-line learning activities that move children from a sense of wonder into meaningful engagement with objects and…

To enhance a course in 3D Virtual Reality (3D VR) modelling for mining engineers, and to create the potential for off campus students to fully engage with the course, a problem based learning (PBL) approach was applied to the course design and all materials and learning activities were provided online. This paper outlines some of the theoretical…

The purpose of this experimental study was to test the role of image and animation on: a) learners' perceptions of pedagogical agent persona characteristics (i.e., extent to which agent was person-like, engaging, credible, and instructor-like); b) agent value; and c) performance. The primary analysis consisted of two contrast comparisons: 1)…

Training firefighters is a difficult process in which emotions and nonverbal behaviors play an important role. The authors have developed a mixed reality environment for training a small group of firefighters, which takes into account these aspects. The assessment of the environment was made up of three phases: assessing the virtual agents to…

This paper reports upon an active learning approach that promotes conceptual change when studying direct current electricity circuits, using free open source software, "Qucs". The study involved a total of 102 prospective mathematics teacher students. Prior to instruction, students' understanding of direct current electricity was…

With the advent of the microcomputer has come an increase in the use of educational simulations. Distinct from software used for drill and practice, tutorials, or problem-solving, simulation software recreates events, devices, or phenomena and can provide the student with a scientific experience which might otherwise be too expensive, dangerous,…

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…
