Students perform intensive web-based applications during their education. One of these is project-based application. In this study, the effect of web based project applications on students' attitudes towards chemistry has been investigated. 42 students attending Hacettepe University, Faculty of Education, and Department of Chemistry Education have…

We report on the initial attempts at evaluating "at scale" a particular technological/curricular innovation that enables more students to develop deeper knowledge. The methods, issues, and findings of the current pilot experiment speak not only to the success of SimCalc MathWorlds, the focus of our research program, but also to the…

Is it possible to educate a fire officer to deal intelligently with the command and control of a major fire event he will never have experienced? The authors of this paper believe there is, and present here just one solution to this training challenge. It involves the development of an intelligent simulation based upon computer managed interactive…

Played in university classes for preservice teachers as well as in middle and high schools, the River Crossing Game depends on the sum of tosses of two fair dice. This paper describes the game as well as some lines of thinking about winning strategies, which are not obvious even with an understanding of the overall distribution for the sum of two…

Central limit theorem (CLT) is considered an important topic in statistics, because it serves as the basis for subsequent learning in other crucial concepts such as hypothesis testing and power analysis. There is an increasing popularity in using dynamic computer software for illustrating CLT. Graphical displays do not necessarily clear up…

Discusses an algorithm for developing problem solving simulations using microcomputers, and describes both the components of the simulation algorithm and the user interface. Examples of simulation and programming methods are presented. (MBR)

Reviews types and evaluates effectiveness of microcomputer-based training for managers: electronic workbooks, simulations/games, expert systems, and management support systems. (SK)

Provides brief descriptions of interactive tutorial and simulation programs for reading, writing, and mathematics; and of drill-and-practice courseware packages. (DMM)

Examines how computer-based simulations can best be exploited for computer-assisted language learning. Three learning environments are discussed: (1) the classroom, (2) a computer lab, and (3) self-access. Various types of computer-based simulations are described, including sports, adventure games, management of resources, and branching stories.…

Using Microsoft Excel, several interactive, computerized learning modules are developed to demonstrate the Central Limit Theorem. These modules are used in the classroom to enhance the comprehension of this theorem. The Central Limit Theorem is a very important theorem in statistics, and yet because it is not intuitively obvious, statistics…

Computer programs and models are used to express respect for life by not sacrificing any animal but these alternatives might be deeply flawed. Alternatives to dissection are perverse alternatives that tend to preserve the features of inappropriate dissections like destructiveness, reductionism and objectification.

Research on psychometric methods is heavily dependent on software. The quality, availability, and documentation of such software are critical to the advancement of the field. In 2000, an ad hoc committee of NCME recommended that NCME adopt policies that promote greater availability and better documentation of software. This article follows the ad…

The ability to scan retention data over a wide range of eluent composition opens up the possibility of a computerized selection of the optimal separation conditions. The major characteristics of retention behavior, peak-shape effects and pH effects evident in ion chromatography (IC) using common stationary phases and eluents are illustrated.

Robots make a wonderful context for teaching students about many concepts important to technological literacy. They can provide an authentic context and produce high levels of motivation. According to Standards for Technological Literacy: Content for the Study of Technology (STL) (ITEA, 2000, 2002), there are six core concepts that should be…

Virtual reality (VR), as an emerging visualization technology, has introduced an unprecedented communication method for collaborative design. VR refers to an immersive, interactive, multisensory, viewer-centered, 3D computer-generated environment and the combination of technologies required to build such an environment. This article introduces the…
