Pedagogical experts contend that students learn best when they are actively involved in and responsible for their own learning. In a student-centered learning environment, the instructor ideally serves primarily as a learning resource or facilitator. With the guidance of the instructor, students in active learning environments strive for…

ProbLab is a probability-and-statistics unit developed at the Center for Connected Learning and Computer-Based Modeling, Northwestern University. Students analyze the combinatorial space of the 9-block, a 3-by-3 grid of squares, in which each square can be either green or blue. All 512 possible 9-blocks are constructed and assembled in a "bar…

This study was designed to examine the effects of the competency (low vs. high) and interaction type (proactive vs. responsive) of pedagogical agents as learning companions (PALs) on learning, self-efficacy, and attitudes. Participants were 72 undergraduates in an introductory computer-literacy course who were randomly assigned to one of four…

New developments in technology, irrespective of the fields. These have a potential role to play in the field of education and training, especially distance education, to transform it into an interactive paradigm. These can provide education beyond the boundaries of a nation and/or state making it accessible to learners at their own pace. These are…

Virtual Enterprises International (VE) is a high school program that teaches students about business through task-oriented and hands-on coursework. With the assistance of a coordinator and business mentors, VE students create and oversee a virtual firm, conducting business with other virtual firms nationally and internationally. The program…

In the 20th century, student work was dominated by paper-print assignments, particularly essays. This was a reflection of the dominant media technology of that century--books, magazines, newspapers, radio, and television. But those days are gone. In the 21st century, the dominant media technology of today's students is the Internet. In addition to…

At some point in their education, pre-engineering students will take physics and/or calculus. For many freshmen who aren't certain about their career paths, taking these courses is a litmus test to determine whether they have the aptitude or desire to pursue an engineering degree. Therein lies the challenge for many students in the U.S. Science,…

This paper describes an election simulation developed at Rutgers University (New Jersey) using Multimedia Toolbook. Toolbook has features which enable an information flow to be presented which mimics the flow of a campaign, using both text and video. Subjects are presented with textual information that flows across the screen, representing the…

A multimedia-style computer application is detailed that facilitates students' role playing in a simulated business situation. The incorporation of video footage lends a "face" to a theoretical client with which the student must interact to bring about the successful resolution of a potential "calamity." The process of video…

Large sample standard errors of linear equating for the single-group design are derived without making the normality assumption. Two general methods based on the delta method of M. Kendall and A. Stuart (1977) are described. One method uses the exact partial derivatives, and the other uses numerical derivatives. Simulation using the beta-binomial…

Equating tests from different calibrations under item response theory (IRT) requires calculation of the slope and intercept of the appropriate linear transformation. Two methods have been proposed recently for equating graded response items under IRT, a test characteristic curve method and a minimum chi-square method. These two methods are…

This paper presents a rationale for using high-fidelity computer simulation in planning for and implementing effective multicultural education strategies. Using computer simulation, educators can begin to understand and plan for the concept of cultural sensitivity in delivering instruction. The model promises to emphasize teachers' understanding…

This study explored ways of developing and utilizing more efficient Computer-Based Instructional Simulations (CBIS) based on the relationship among fidelity levels (i.e., how closely a simulation imitates reality), transfer time, and learning time. The hypotheses presented suggest how to determine the optimal shifting points of the fidelity…

The purpose of this study was to examine Edward Lorenz's psychological processes and other environmental aspects in the discovery of chaos at that time. The general concept of chaos is discussed based on relations with previous scientific theories such as Newtonian physics and quantum mechanics. The constraints of discovery in terms of available…

This paper describes three computer-based simulators developed to support an undergraduate computer architecture course. Using a hypermedia authoring package, a simulator was created for each of the three course content areas: (1) introduction of the hypothetical computer structure--contains a tutorial, a quiz, and a simple program that presents…
