The process of developing concepts of time continues from age 5 to 11 years (Zakay, 1998). This study sought the representation mode in which children could best express time concepts, especially the proper arrangement of events in a logical and temporal order. Usually, temporal order is examined and taught by 2D (2-dimensional) pictorial scripts.…

P. Bloom's (1990) data on subject omission are often taken as strong support for the view that child language can be explained in terms of full competence coupled with processing limitations in production. This paper examines whether processing limitations in learning may provide a more parsimonious explanation of the data without the need to…

High school teacher Cara M. Arver walks teachers through her experience of setting up a virtual world to augment students' reading of "Lord of the Flies." Students interact as additional characters, discuss and solve problems based on the circumstances of the story, and complete classroom assignments within a virtual environment.

This document consists of a curriculum guide combined with separately published "Simulations" and "Test Bank" volumes designed to support instructors using the curriculum guide. The curriculum guide was developed to provide instructional materials to teachers of office support systems courses in Texas. The guide contains the…

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…

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)…

Use of educational games to supplement traditional classroom lectures is purported by some researchers to increase interest, motivation, and retention, as well as to improve higher order thinking and reasoning skills. This paper reviews proposed benefits of using games as cognitive tools, and discusses the complexities of assessing those benefits.…

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…

An overview of the current status of the videodisc industry and observations on future directions for videodisc technology are presented in this paper. Information was drawn from interviews with presenters at the 1984 Nebraska Videodisc Symposium and the February 1985 Society for Applied Technology Conference, discussions with hardware…

This report presents examples of Rand's current research in the information sciences and illustrates the application of information science tools to specific policy studies. The projects discussed depict Rand's success with using corporate seed money to bridge the gap between the research and development of new information science tools and…

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…

The purpose of this study was to use realistically simulated data to evaluate various CAT designs for use with the verbal reasoning measure of the Medical College Admissions Test (MCAT). Factors such as item pool depth, content constraints, and item formats often cause repeated adaptive administrations of an item at ability levels that are not…

This study looked at the effect of contextual advisement and competition on transfer of mathematics skills in a computer-based instructional simulation game and simulation in which game participants helped their "aunt and uncle" fix up a house. Competition referred to whether or not the participant was playing against a computer…

Describes a project where fourth- and fifth-grade students in the Wales School District (Wisconsin) simulated a political campaign as part of their social studies curriculum, using HyperStudio, ClarisWorks, and the Internet. Also discusses fund-raising activities and how the unit came about. (AEF)
