In Ramsay-curve item response theory (RC-IRT), the latent variable distribution is estimated simultaneously with the item parameters. In extant Monte Carlo evaluations of RC-IRT, the item response function (IRF) used to fit the data is the same one used to generate the data. The present simulation study examines RC-IRT when the IRF is imperfectly…

This book, written by authors representing 12 countries and five continents, is a collection of international perspectives on distance learning and distance learning implementations in higher education. The perspectives are presented in the form of practical case studies of distance learning implementations, research studies on teaching and…

The political system of the Federal Republic of Germany (West Germany) is explained and comparisons are made with the U.S. system. Descriptions are given of the West German political parties and the process and importance of forming coalitions is explained. A lesson plan is presented that utilizes the case study and includes a simulation exercise…

Discusses a comparative study of two fourth grade social studies teaching programs based upon study units concerning flight. Concludes that both Hilda Taba's Teaching Strategies Program and the published simulation program "Flight" were exciting alternative methods of teaching map reading to fourth graders. Reports that students using…

Complex decision-making environments often demand that a range of alternative strategies be identified and compared for their shared value in achieving desired ends. Simple parametric statistical procedures such as analysis of variance and discriminant function analysis can be used in such situations to compare (using selected criteria) the value…

Describes the emphasis of decision support systems as being on the decision making process itself, rather than the flow of information; reviews the uses of microcomputers in libraries in recent years; and compares five decision modeling software packages. An appendix lists the name, manufacturer's address, price, and hardware requirements of each…

To better understand the issues behind the colonization of the New World and to see why some colonies and empires failed while others flourished, students analyze the motivations and resources of the colonial powers. Noting that the results of the colonial era are counter-intuitive (the Spanish, who colonized areas rich in gold, silver, and…

Four mentally retarded adults received single case instruction, followed by general case instruction, on washing machine and dryer use, using either actual appliances or simulation. Generalization errors were affected by single/general case instruction, not by use of simulated versus natural conditions. General case simulation was more efficient…

Describes, compares, and evaluates 10 computer-scored business games that include marketing, finance, and production functions. Methods for depicting the economy and industry are discussed, a learning model is used to explain teaching qualities of the games, and their value in the classroom is emphasized. (LRW)

Explores classroom microcomputer applications in elementary and secondary social studies. The utility of drill and practice and tutorial programs is reviewed; computer spreadsheets to project election tallies and databases for use in analyzing voter data are described; and economics and election simulations are compared. (MBR)

A study compared the effectiveness of traditional and computer-simulation methods for teaching pharmacy financial management in continuing education. Retention of material was similar for the groups (n=26 and n=24 students, respectively), and similar amounts of time spent on financial management were found in a followup. Both methods were found…

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…

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…

A classroom study in two advanced Chinese language courses compared the effectiveness of two instructional strategies: (1) proficiency-based instruction through cooperative learning (Chinese 405) and (2) "prochievement," a hybrid, performance-based strategy derived from both proficiency and achievement approaches (Chinese 406). Subjects…

Discusses a survey of 56 advanced placement (AP) U.S. history teachers. Explores the scope of AP history and types of posttest activities used after Advanced Placement examinations. Concludes that public school courses developed more deeply into post-1960 events than the private schools did. Describes movies, debates, simulations, and local…
