Computerized case simulations have considerable potential application in counseling psychology. Methods have been demonstrated in the present study for quantifying and evaluating performance of both individuals and groups of subjects; these methods appear promising. (Author)

Describes an economics game for adult education designed to simulate the real world by setting up national economic policymaking in which participants can exercise their own judgment. Assesses some of the conclusions to be derived from the use of such a game. (MF)

Investigates the effects of selected characteristics of a web-aided instructional simulation on students' conceptual change, problem solving, and transfer abilities. Conducts a two-pronged research study with (n=117) students enrolled in a beginning meteorology course at Iowa State University. Compares three groups--with-log group, without-log…

Attaining the insight needed to solve the Mutilated Checkerboard problem, which requires discovery of an effective problem representation (EPR), is described. Performance on insight problems can be predicted from the availability of generators and constraints in the search for an EPR. Data for 23 undergraduates were analyzed. (TJH)

The effectiveness of computer simulation in enhancing learning of a health unit by 30 mildly learning-disabled high school students was investigated. Results indicate that computer simulation in combination with structured teaching was effective, particularly in the area of teaching problem-solving skills. (TJH)

Discusses the implications of authentic activity as a model of learning, particularly in the design of computer-based simulations and project-based learning activities. Addresses the characteristics of problem-solving situations, educational simulations, and authentic learning activities; and identifies key guidelines in the design and development…

This paper uses the topic of rain forests to demonstrate how a meaningful and relevant Science, Technology, and Society program can be designed for intermediate-level students. Students create and immerse themselves in a tropical rain forest, explore the forest ecosystem and peoples, and consider solutions to the problem of deforestation. (JDD)

An investigation designed to test the effectiveness of a computer program is described. The purpose was to determine whether the use of a simulation referred to as "The Factory" leads to higher scores on a standardized test of problem-solving ability. The procedures, results, and implications for science teaching are included. (KR)

Some commercially available software tools that have potential applications in the analytical chemistry curriculum are surveyed and evaluated. Tools for instruction, analysis and research, and courseware development are described. A list of the software packages, the compatible hardware, and the vendor's address is included. (KR)

To examine cultural differences in planning processes, two instruments, one of which was a computer simulation, were used with 38 Brazilian and 38 German university students. Results are discussed from a functional perspective that interprets cognitive processes within their ecocultural context. (SLD)

Describes how an 11th-grade English teacher promoted active learning in her class through a hands-on project that required group problem solving, decision making, and technical writing skills. Discusses how the students simulated a toy factory by working collaboratively in teams to design, build, and market a LEGO toy. (RS)

This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…

Finite mixture models are well known to have poorly behaved likelihood functions featuring singularities and multiple optima. Growth mixture models may suffer from fewer of these problems, potentially benefiting from the structure imposed on the estimated class means and covariances by the specified growth model. As demonstrated here, however,…

Least squares regression is the most common method of fitting a straight line to a set of bivariate data. Another less known method that is available on Texas Instruments graphing calculators is median-median regression. This method is proposed as a simple method that may be used with middle and high school students to motivate the idea of fitting…
