The purpose of this study was to investigate the effects of using individual, cooperative-dyad, and collaborative-dyad learning structures with a computer simulation. College students implemented and experienced one of the three learning structures while using a computer simulation designed to teach the technical and procedural aspects of…

Second language tests claiming to assess communicative competence are widespread, despite the vague nature of the construct. Sociolinguistic or intercultural competence is gradually gaining attention in the classroom, but testing has not kept pace, partly because of difficulty in defining the related skills. An opinion is that speech act theory…

This paper describes the effects of the implementation of constructivist techniques with interactive computer simulations on conceptual understanding of plant nutrition and critical thinking skills in heterogeneously grouped secondary biology classrooms. The study focused on three strategies for teaching plant nutrition: (1) traditional; (2)…

Many educators are shifting their teaching strategies and approaches to include more emphasis on critical thinking skills, the communication of ideas, a variety of approaches to content emphasizing varied student learning styles, and the need to draw explicit connections among topics for retention of learning. Real-world assessment measures, then,…

This paper describes a tele-educational environment and reports on experiences obtained during international trials. The tele-educational environment is built around the metaphor of a college. The virtual college offers the opportunity for students to participate in desktop tele-education from their homes or offices. The environment is based on…

Construction of a work sample test, the Investigator Planning Exercise (IPE), for the job of detective in the Chicago (Illinois) Police Department is described. Simulated crime scenarios, a mock crime scene, and five checklists of necessary skills (i.e., ability to summarize and communicate facts, identify inconsistencies, and determine the next…

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…

This study examined performance of a simulated computerized adaptive test that was designed to help direct the development of a medical recertification examination. The item pool consisted of 229 single-best-answer items from a random sample of 3,000 examinees, calibrated using the two-parameter logistic model. Examinees' responses were known. For…

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…

This final report describes the development of eight computer based science simulations designed for use with middle school mainstreamed students having learning disabilities or mild mental retardation. The total program includes software, a teacher's manual, 3 videos, and a set of 30 activity worksheets. Special features of the software for…

This publication is designed to help students prepare for participation in Model United Nations activities. A Model U.N. conference simulates the activities of a United Nations body, usually the Security Council or the General Assembly and its committees. Participants assume the roles of representatives of Member States to the United Nations…

This document presents information on the Model United Nations Program, including historical background, a description of how the Program works, and three steps for establishing a Model U.N. Program. A list of Model U.N. Publications and resources is included. (DB)

The conference reported in this document provides a meeting place for researchers from around the world, where the emphasis is on new ideas connected to computer technologies in education. This volume contains 140 extended abstracts selected by the program committee and organized into the following categories: (1) educational informational…

This paper discusses the role that foreign language programs should play in targeting their instruction to the particular needs of students, whether they are studying business, science, or other technical fields. It also describes an English-German negotiation simulation for final year students in the International Business and German course at…

This paper describes a special class program for gifted students (aged 9 to 12) with learning disabilities in Calgary (Alberta). The program has evolved over its 4 years to stress kinesthetic, experiential learning. The issue of remediation versus enrichment was resolved when it was found that the students responded best to whole theme…
