Investigates the effects of using molecular modeling on students' spatial ability, understanding of new concepts related to geometric and symbolic representations, and perception of the model concept. (Author/CCM)

Evaluates first-year college students' perceptions of molecular modeling. Examines the effectiveness, integration with course content, interests, benefits, advantages, and disadvantages of molecular modeling. (Author/CCM)

Reports on the increasing use of virtual-reality devices at Pennsylvania State University's Milton S. Hershey Medical Center and other institutions that allow medical residents to practice their skills in simulated operations. Notes that both students and professors are enthusiastic about the simulations but that the necessary technology and…

Decribes a variation on Bingo that provides a non-routine probability investigation through which students develop concepts of chance. (Author/CCM)

Experiments in an accelerating frame are hard to perform. Illustrates how simple computer software allows sufficiently rapid and accurate measurements to be made on an arrangement of weights and pulleys known as Atwood's machine. (Author/CCM)

Discusses problems associated with organizational or technological change. Presents the results of learning experiments in experimentaria, rooms for experiments removed from the daily activities of an organization. Concludes that experimentaria seem to create a higher level of self-respect and respect for others' skills and knowledge as well as a…

Developed models to investigate the fit of parametric item response models by comparing them to models fitted under nonparametric assumptions. Illustrated these techniques through simulation studies and real-data examples. Discusses the identifiability and estimation consistency of item response theory models. (SLD)

Presents a new nonparametric method for constructing a spatial representation of multidimensional test structure, the Conditional Covariance-based SCALing (CCSCAL) method. Describes an index to measure the accuracy of the representation. Uses simulation and real-life data analyses to show that the method provides a suitable approximation to…

A workshop for Australian nursing students used simulation to impart information about illicit drug use and enhance nurses' ability to care for patients who use drugs. Simulations challenged attitudes, beliefs, and stereotypes and expanded students' knowledge about health promotion and patient care. (Contains 18 references.) (SK)

In the future, virtual reality technology based initially on data from Visible Human Data sets will provide the majority of simulation-based training. Indicates that evidence-based outcomes must show these systems to be effective instruments for teaching and assessment, and medical educators must be willing to effect change in medical education to…

A hands-on group of seventh graders in technology education (n=29) used Legos and another group (n=29) used Gryphon Bricks simulation software for problem solving. Analysis of teacher ratings of solutions revealed no differences in creativity, originality, or usefulness of the products. (Contains 34 references.) (SK)

Describes development of a computer-based simulation program for training school personnel in crisis management. Addresses the data collection and analysis involved in developing a simulated event, the systems requirements for simulation, and a case study of application and use of the completed simulation. (Contains 21 references.) (Authors/PKP)

In this paper, we present our experiences in using two automatic assessment tools, TRAKLA and TRAKLA2, in a second course of programming. In this course, 500-700 students have been enrolled annually during the period 1993-2004. The tools are specifically designed for assessing algorithm simulation exercises in which students simulate the working…

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…

According to temporal distinctiveness models, items that are temporally isolated from their neighbors during list presentation are more distinct and thus should be recalled better. Event-based theories, by contrast, deny that time plays a role at encoding and predict no beneficial effect of temporal isolation, although they acknowledge that a…
