Two approaches for conceptualizing and estimating a contextual model for analyzing student achievement are the separate equation approach and the single equation approach. The separate equation method determines the relationship between the individual-level independent variable and the individual-level dependent variable within each group. It then…

Discusses computer simulations in science education and presents the results of a study of 39 ninth-grade earth-science students to determine the effects of computer-simulated mineral identification activities on test performance. Results indicated no difference in test scores between the group using real minerals and the group using a computer…

The regression-discontinuity approach to evaluating educational programs is reviewed, and regression-discontinuity post-program mean differences under various conditions are discussed. The regression-discontinuity design is used to determine whether post-program differences exist between an experimental program and a control group. The difference…

Teachers College of Columbia University (New York) and the Dalton School, an independent school in New York City, have collaborated on the Dalton Technology Project and its "Archaeotype" program which presents students with a graphic simulation of an archeological site. Students simulate digging up the artifacts, use reference sources to…

Annual use of fuel oil for heating schools and other facilities of the Montgomery County (Maryland) Public Schools, Montgomery County Government, and Montgomery College exceeds four-million gallons. This report examines the processes by which purchases and distributions of fuel oil are made, makes recommendations based on the examination, and…

Reports on a program developed in Indiana public schools to hold software evaluation workshops that would compare teacher and student evaluations of the same software. The evaluation process is discussed; tutorials, drill and practice programs, simulations, and games are examined; and tests for correlation are described. (21 references) (LRW)

Describes a study conducted at the University of Iowa College of Dentistry that compared the effectiveness and efficiency of adaptive instruction with nonadaptive instruction using interactive videodisc patient simulations. The Dental Diagnosis and Treatment (DDx&Tx) System is explained, and problem-solving skills and study time are discussed.…

This study sought to address the lack of experimental research examining the influence of contextual factors on African American students' learning. A total of 162 low-income African American and White fourth graders were randomly assigned to ethnically homogeneous, communally structured groups of three to work on a motion acceleration task using…

Technology holds the key for bridging the gap between access to quality education and the need for enhanced learning experiences. This book contains case studies on divergent themes of personalized learning environments, inclusive learning for social change, innovative learning and assessment techniques, technology and international partnership…

A Monte Carlo study was conducted to compare the performance of three statistical indices of test item bias in small samples of examinees. The statistical indices compared were the Delta method, the Mantel-Haenszel (MH) method, and the Standardization method. Sample sizes of 50, 100, and 200 were examined. One thousand samples of each size were…

A predictive adaptive testing (PAT) strategy was developed based on statistical predictive analysis, and its feasibility was studied by comparing PAT performance to those of the Flexilevel, Bayesian modal, and expected a posteriori (EAP) strategies in a simulated environment. The proposed adaptive test is based on the idea of using item difficulty…

Student achievement, cost, rural context, and qualitative differences relative to small/rural schools were analyzed in Alberta to address the choice between small elementary school construction and school consolidation with student busing. Studies in both the United States and Canada have found no consistant significant differences in student…

Describes three studies which explored the use of computer assisted instruction with mildly handicapped secondary school students. Comparisons with non-handicapped students are made in vocabulary development, using drill and practice; concept instruction in elementary logic, using a tutorial approach; and problem solving in health education, using…

Previous studies established that 6 hours of instruction focusing on cognitively demanding aspects of computer use were sufficient to reduce computer anxiety significantly among teacher education students. This paper reports on a study of whether or not it is possible to reduce anxiety at least as efficiently by providing a similar length computer…

Two studies were carried out to evaluate the quality of multidimensional item response theory (MIRT) model parameter estimates obtained from the computer program NOHARM. The purpose of the first study was to compute empirical estimates of the standard errors of the parameters. In addition, the parameter estimates were evaluated for bias and the…
