Suggested are activities using a Polaroid camera to illustrate the capabilities of remote sensing. Reading materials from the National Aeronautics and Space Administration (NASA) are suggested. Methods for (1) finding a camera's focal length, (2) calculating ground dimension photograph simulation, and (3) limiting size using film resolution are…

Trickshot! is an exploratory environment that allows learners to experiment with various physical properties to develop an intuitive understanding of the behavior of objects in physical systems. The software is geared to secondary students with little exposure to pool or physics. When used in conjunction with meaningful class activities, such an…

Discusses the computer as a communication medium to support learning. Illustrates the benefits of this reconceptualization in the context of having students author and play interactive simulation games and exchange them over the Internet. (RS)

Describes a pencil-and-paper examination procedure that simulates the use of the computer for the evaluation of student performance in graduate research methods courses. Using this simulation, the examination can be administered in regular classrooms without the availability of computers. Includes a copy of the midterm examination. (Author/PEN)

Presents a unit on chemical reaction kinetics that consists of a predemonstration activity, the demonstration, and a set of postdemonstration activities that help students transfer the concepts to actual chemical reactions. Simulates various aspects of chemical reaction kinetics. (JRH)

Type I error rates for the likelihood ratio test for detecting differential item functioning (DIF) were investigated using Monte Carlo simulations. Type I error rates for the two-parameter model were within theoretically expected values at each alpha level, but those for the three-parameter model were not. (SLD)

Examined whether differences in students' self-reported knowledge, cynicism, and political participation depended on whether their American government college course included a character-playing simulation involving members of Congress. Discusses research hypotheses and describes testing for immediate effects as well as after three years.…

Describes a study conducted in Israel that investigated whether the caregiver's awareness to the emotional experiences that toddlers undergo in the first days in kindergarten improves through a virtual reality simulation of a toddler's world. Explains the use of virtual reality technology to simulate a toddler's first few days' experiences in a…

Discusses computer assisted learning and simulation modeling from a United Kingdom perspective. Highlights include modeling with the DMS (Dynamic Modelling System); modeling with STELLA; learning and teaching simulation modeling; educational development roles for learning technologists; and a list of relevant Web sites. (Contains 52 references.)…

A selection model for meta-analysis is proposed that models the selection process and corrects for the consequences of selection by publication on estimates of the mean and variance of the effect parameters. Simulation studies show that the model substantially reduces bias when the model specification is correct. (SLD)

As the focus shifts to learning in the workplace, emphasis is being placed on "infonuggets," chunking, or granularization: delivery of bits of training and information as needed on the job. Some delivery methods include electronic performance support systems, the Internet, and computer simulation. (SK)

Describes an assignment for an introductory computer science class that requires the student to write a software program that simulates an automated teller machine. Highlights include an algorithm for the assignment; sample file contents; language features used; assignment variations; and discussion points. (LRW)

Draws on numerous different content areas in the development of a 4-to-6 week long unit with the culminating activity of a simulated Mexican cafe. Students assume the roles of restaurant personnel and greet customers, take and fill orders, cook a variety of Mexican entrees, tally the check, and make change, all in the target language while…

Developed an item response model for characterizing test-compromise that enables the estimation of item preview and score-gain distributions. In the approach, models parameters and posterior distributions are estimated by Markov Chain Monte Carlo procedures. Simulation study results suggest that when at least some test items are known to be…

Statistical properties of person fit indices are reviewed as indicators of the extent to which a person's score pattern is in agreement with a measurement model. Distribution of a fit index and ability-free fit evaluation are discussed. The null distribution was simulated for a test of 20 items. (SLD)
