Type I error rates of four multivariate tests (Pilai-Bartlett trace, Johansen's test, James' first-order test, and James' second-order test) were compared for heterogeneous covariance matrices in 360 simulated experiments. The superior performance of Johansen's test and James' second-order test is discussed. (SLD)

Contends that empirical research using laboratory experimental economics has flourished during the past decade. Discusses how two practitioners of experimental economics integrated their research interests into undergraduate economics education. Describes three computerized exercises and includes samples of student handouts and activities. (CFR)

Describes an approach to teaching the scientific method where an outbreak of cholera within the school is simulated. Students act like epidemiologists in an attempt to track down the source of the contamination. (PR)

Unlike traditional objective testing methods, alternative assessments encourage student involvement in real-life problems and challenges. The teacher's role is to help students determine and identify assessment tasks and criteria, participate in ongoing assessment of work in progress, and propose alternative ways to meet criteria.

Business schools across the country are specializing in electronic commerce, in which teams of students create online businesses available on the Internet only to participating institutions. The courses offer students an opportunity to see how an online retailing business is conducted, including creating and maintaining Web sites, advertising…

Touts the advantages of experiential learning through educational games, or simulations, as provided by outdoor-learning centers. The organization of outdoor learning is discussed along with ways for integrating community groups into the activities. Included are five examples, a bibliography, and contact information for two centers that support…

Describes strategies for teaching middle school students in a manner that promotes inclusion while allowing for individual differences, including the needs of special-needs students. Strategies discussed include the use of journals, student designed projects, hands-on experiences, and role play or simulation. (DB)

Describes the development of a speech-activated multimedia system for foreign-language training. The model allows students to engage native speakers on CD-ROM in lengthy face-to-face dialogs using natural spoken language. (Author/VWL)

Describes a study of college students who designed and conducted experiments involving control of variables after being assigned to one of four versions of a computer-based biology simulation learning environment. Finds that reason-justification prompts directed students' attention to understanding the employment of experimental design principles…

Examines the importance of the instructional systems design (ISD) model in designing the presentation and content of technology-based learning (TBL) environments, especially for adult learners. Describes TBLs and their use in university and adult learning and discusses the most common presentation methods: drill and practice, tutorial, simulation,…

Comparison of 2 groups of graduate rehabilitation counseling students who did (n=20) or did not (n=18) participate in a wheelchair sensitivity training exercise found significant differences in responses to questions pertaining to daily frustrations experienced by people with physical disabilities and a preoccupation with accessibility. Discussion…

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…

This instructional design looks at momentum in physics through railroading, to assist students in developing appropriate mental models that will enable them to solve problems relevant to the process or principle being taught. A PEAnet (process, entity, activity network) relationship enables an instructional visualization (simulation) in which…

Over the years, the Association for Business Simulation and Experiential Learning (ABSEL) has invested considerable effort in formulating its research mission while reflecting on its unique identity among professional organizations. This article reviews the literature on this topic while identifying key issues and proposals. It then discusses the…

The analytically derived asymptotic standard errors (SEs) of maximum likelihood (ML) item estimates can be approximated by a mathematical function without examinees' responses to test items, and the empirically determined SEs of marginal maximum likelihood estimation (MMLE)/Bayesian item estimates can be obtained when the same set of items is…
