Changes in DNA base-repair may serve as an indicator of the time elapsed since divergence from a common ancestor. DNA sequences can now be analyzed. The simulation presented in this article allows students to observe the accumulation of changes in a randomly mutating sequence of playing cards. The cards are analogous to DNA nucleotide or protein…

This article reviews current methods for evaluating models in the cognitive sciences, including theoretically based approaches, such as Bayes factors and minimum description length measures; simulation approaches, including model mimicry evaluations; and practical approaches, such as validation and generalization measures. This article argues…

Corrective feedback (CF) has been investigated in relation to learners' error types that trigger CF and learners' responses to CF. These research findings generally suggest that recasts, the most frequently used type of CF, did not trigger learners' reformulation of their erroneous utterances very frequently. In these studies, however, teachers'…

U.S. state educational testing programs administer tests to track student progress and hold schools accountable for educational outcomes. Methods from item response theory, especially Rasch models, are usually used to equate different forms of a test. The most popular method for estimating Rasch models yields inconsistent estimates and relies on…

An interactive simulation program was developed for use in teaching students how to handle public relations problems. The program user is placed in the role of assistant newsletter editor, facing a series of decision-making situations. Each choice the user makes affects the subsequent reality created by the program, which is designed to provide…

This article introduces "expertise-based training" (XBT) as an instructional design theory that draws on the theories, findings, and methods of expertise research in order to create instructional strategies that can hasten the development of advanced learners into experts. The central tenants of XBT are: 1) Key cognitive sub-skills that…

The main concern of the present study is to probe the relationship between note-taking strategy and students' listening comprehension (LC) ability. To conduct the study, a language proficiency test was administered to the undergraduate students majoring in English Translation at Shahid Chamran University of Ahvaz and sixty students were selected…

Much of the literature theorising mobile learning emphasises the importance of context with physical and social contexts identified to date. Our work to design and implement authentic mobile simulation activities using SMS text messaging suggests that a third context may also be important. This is a virtual context, the learner-created cognitive…

Simple role-play simulations can not only demonstrate the dynamics of a conflict but also create awareness of multiple perspectives even among populations relatively set in their opinions. To teach my student population of military officers, I utilize simple, nongame simulations of multisided Middle East conflicts that not only facilitate learning…

This article calls for renewed emphasis on the use of on-campus microteaching to facilitate simultaneously preservice teachers' performance of effective teaching skills and their capability to reflect meaningfully on their emergent teaching actions. In making a case for greater focus on the implementation of microteaching in preservice teacher…

Chapters in this book include: (1) Courseware Adaptation to Learning Styles and Knowledge Level (Boyan Bontchev and Dessislava Vassileva); (2) Assisted On-Job Training (Claudio Teixeira and Joaquim Sousa Pinto); (3) Self-Directed Learning Readiness Factors in Physicians for Implementing E-Learning in the Continuing Medical Education Programs…

A discussion of how to construct simulation games for all subject areas in a systematic manner. (HB)

Speech delivered at the Conference on Research in Medical Education, 79th Annual Meeting of the Association of American Medical Colleges (Houston, Texas, November 1, 1968).

Georgia Educational Models (GEM) will proceed to utilize computers and simulation to their fullest cost effectiveness potential simultaneously in operation and in research, while avoiding both the restrictions and duplications which come from doctrinaire insistence on maintaining an artificial separation between management and research uses of…

This manual contains 1) a one-page discussion of the development in 1966 of "Policy Negotiation Simulation," a game which simulates the collective bargaining negotiations between school board and teachers' representatives; 2) description of the subsequent use of the Policy Negotiation Simulation as "a simulation for building…
