Describes research within physical science courses for preservice elementary teachers, where groups of students had access to computers, examining how computers were used as representational tools to support meaning-making conversations within groups. Notes how special computer simulators facilitated student groups' construction of robust…

Discusses the impact of computer technology on education, highlighting concept maps, electronic learning logs, and computer simulations, which provide students deeper understanding of chemistry and research methods while doing real science and help teachers conduct ongoing formative assessment of class progress. Computer simulations help teachers…

Discusses the design and use of intelligent tutoring systems (ITS) for computerized business simulations. Reviews the use of ITS as an instructional technology; presents a model for ITS-based business simulations; examines the user interface and link between the ITS and simulation; and recommends expert-consultant diagnostic testing, and…

The purpose of this study was to examine how 3-dimensional (3-D) models of the Solar System supported student development of conceptual understandings of various astronomical phenomena that required a change in frame of reference. In the course described in this study, students worked in teams to design and construct 3-D virtual reality computer…

Nurturing reflective teaching and improving critical-thinking instruction are two important goals in teacher education, but these are only achievable when teachers-in-training are provided with opportunities for building professional knowledge and for exhibiting reflective teaching practices. A computer simulation program (CS-TGCTS) was therefore…

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer-based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies…

In this paper it is presented a virtual organizational environment, conceived with the integration of three computer programs: a manufacturing simulation package, an automation of businesses processes (workflows), and business intelligence (Balanced Scorecard) software. It was created as a supporting tool for teaching IE, its purpose is to give…

One principle of applied research is to design intervention programs targeted to teach useful skills to the participants (Baer, Wolf, & Risley, 1968), while structuring the program to promote generalization of the skills to the natural environment (Stokes & Baer, 1977). Proficiency in community skills (e.g., community navigation and…

Rapid advancements in hardware, software, and connectivity are helping to shorten the times needed to develop computer simulations for science education. These advancements, however, have not been accompanied by corresponding theories of how best to design and use these technologies for teaching, learning, and testing. Such design frameworks…

Analysis of variance (ANOVA), a technique included in many introductory statistics courses, analyzes the relationship between a quantitative dependent variable and one or more independent qualitative variables. The nature of the relationship is expressed in a model with unknown parameters. Many textbooks emphasize the mechanics of the technique…

The relationship between educational theories, game design and game development are used to develop models for the creation of complex learning environments. The Game Object Model (GOM), that marries educational theory and game design, forms the basis for the development of the Persona Outlining Model (POM) and the Game Achievement Model (GAM).…

Present engineering has to deal with increasingly complex systems. In particular, this is the case in electrical engineering. Though this is obvious in microelectronics, also in the field of power systems engineers have to design, operate and maintain highly complex systems such as power grids, energy converters and electrical drives. This is…

What pass for the study of international relations is often more an examination of foreign affairs, transnational interaction from ethnocentric perspectives. Many analysts accept the assumptions and values of their own political culture, then superimpose them on other nations. If another state does not act in accordance with those values, its…

For the thirty-sixth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…

Today, at the end of 2007, there are evident consolidations in wireless, storage, and virtualization and the path forward seems clearer now than previously. Trends from last year continue strongly, particularly Web 2.0 and the shift to user-driven environments and Internet sites where significant data and video processing is available to those…
