Uses the case study approach to introduce students to the relationship between science and society. Develops an awareness of ethics, specifically on DNA research, through computer simulations and Internet conferencing. (Contains 20 references.) (YDS)

Discussion of drug education for fifth grade students focuses on a computer simulation in which students role-play adolescents encountering various situations where there is drug or alcohol involvement. Activities in the simulation are explained, and discussion groups that occur following the simulation are described. (LRW)

Examines the effects of using LOGO, or problem-solving- oriented simulation software on locus of control, self-esteem, and achievement motivation for fifth-grade students. The importance of these variables in predicting LOGO mastery and far-transfer problem-solving ability was also examined. (Author)

Discusses the mathematical model presented by Vito Volterra to describe the dynamics of population density. Discusses the predator prey relationship, presents an computer simulated model from marine life involving sharks and mackerels, and discusses ecological chaos. (MDH)

A method is proposed for sequential evaluation of reliability of psychometric instruments. Sample size is unfixed; a test statistic is computed after each person is sampled and a decision is made in each stage of the sampling process. Results from a series of Monte-Carlo experiments establish the method's efficiency. (SLD)

Discusses the activities of Junior Achievement of Georgia in its efforts to promote economic education. Describes programs developed on economics: a textbook, workbook exercises, a student company activity, computer based simulation, and a business consultancy. Explains the development of a curriculum for kindergarten through sixth grade and…

Methodology is suggested for several statistical procedures to detect polytomously scored items that function differently for two subgroups of examinees. The 3 methods are alternative ways of combining the data from 2 x "k" tables. Simulation results demonstrate the superiority of two of the methods, designated HW1 and HW3. (SLD)

Techniques for adjusting census figures are discussed, with a focus on sampling error, uncertainty of estimates resulting from the luck of sample choice. Computer simulations illustrate the ways in which the smoothing algorithm may make adjustments less, rather than more, accurate. (SLD)

A two-stage process that considers the multidimensionality of tests under the framework of unidimensional item response theory is described and evaluated. Findings from a simulation indicate that gains in estimation robustness and score interpretation are possible with almost no sacrifice of goodness of fit when using this two-stage approach. (SLD)

Technology offers tools and information that students need to explore real-world mathematical connections and investigate questions reflecting their own interests. This article illustrates how students can use technology to gather and interpret information, perform descriptive and graphical analysis, make statistical predictions, and create and…

Describes a partnership between Wake Forest University's graduate school of management and an elementary school that resulted in the development of a computer simulation game that integrated technology into the fifth-grade curriculum via a business simulation where players set up and run their own dinosaur amusement park. (LRW)

Describes and contrasts the two authors' teaching styles. Proposes dimensions on which simulation teaching style and game administration design might vary. Argues that teaching style and game design have a considerable impact on learning-related outcomes from simulation. Recommends that the relationship between teacher/administrator behaviors,…

Presents evidence for students' qualitative and quantitative difficulties with apparently simple one-dimensional relative-motion problems, students' spontaneous visualization of relative-motion problems, the visualizations facilitating solution of these problems, and students' memories of the online computer simulation used as a framework for…

Reviews an article that explains BRIDGE, a computerized cost simulation model that compares the cost of expanding a campus through distance instruction versus traditional classrooms. Results of case studies showed that if a television broadcast-delivered class has an enrollment of 150-300 it can be cost competitive with the traditional classroom.…

Nurturing reflective teaching and improving critical-thinking instruction are two important goals in teacher education, but these are only achievable when teachers-in-training are provided with opportunities for building professional knowledge and for exhibiting reflective teaching practices. A computer simulation program (CS-TGCTS) was therefore…
