A new, simple classroom technique helps cell biology students understand principles of Michaelis-Menten enzyme kinetics. A student mimics the enzyme and the student's hand represents the enzyme's active site. The catalytic event is the transfer of marbles (substrate molecules) by hand from one plastic container to another. As predicted, increases…

This paper proposes criteria that instructors should be sensitive to when evaluating simulations or role-plays for use in international/comparative politics courses. The potential benefits and drawbacks to these interactive exercises are addressed as well as the special circumstances that must be taken into consideration to reap the full promise…

This study addressed recruiting principals into low performing schools. A sample (N=619) of principals, assistant principals, central office administrators, school counselors, and teacher-leaders from the 29th largest school district in the United States role-played as applicants for principal vacancies at schools classified as low-performing…

The purpose of this study was to investigate how exposure to classroom instruction affected the use of a computer simulation that was designed to provide students an opportunity to apply material presented in class. The study involved an analysis of a computer-based crisis communication case study designed for a college-level public relations…

Today, at the end of 2007, there are evident consolidations in wireless, storage, and virtualization and the path forward seems clearer now than previously. Trends from last year continue strongly, particularly Web 2.0 and the shift to user-driven environments and Internet sites where significant data and video processing is available to those…

Graphical plans for construction of machinery and architecture have evolved over the last 6,000 years beginning from hieroglyphics to drawings on printable media, from the "Golden Age" of engineering graphics to the innovation of computer graphics and prototyping. The evolution of engineering design graphics as a profession has also evolved. Years…

This is the final evaluation report of the On Growth and Form (OGAF): Learning Concepts of Probability and Fractals by Doing Science project that aimed at engaging high school students in hands-on science activities, experiments, and computer simulations that use probability and fractal geometry to model ragged structures in the real world.…

This guide provides activities that have pupils actively involved, obtaining knowledge through cognitive, affective, or kinesthetic approaches to learning. The book is divided into three sections. Section 1, "Map Skills--Physical and Political Features", includes simulations, simulated review games, and problem-solving dilemmas to employ the use…

In this study, learners worked with a simulation of harmonic oscillation. Two supportive measures were introduced: model progression and assignments. In model progression, the model underlying the simulation is not offered in its full complexity from the start, but variables are gradually introduced. Assignments are small exercises that help the…

As part of the research leading to the implementation of computer-based case simulations (CCS) for the licensing examinations of the National Board of Medical Examiners, gender differences in performance were studied for one form consisting of 18 cases. A secondary purpose of the study was to note differences in style or approach that might…

This brief paper is an anecdotal commentary on a class exercise developed for an advanced European History course covering the period 1815 to the present. It describes a role-play, case-study exercise designed to reinforce previously covered material. Students are directed to attend a mock peace conference to consider if any one country was…

In person-fit analysis, the object is to investigate whether an item score pattern is improbable given the item score patterns of the other persons in the group or given what is expected on the basis of a test model. In this study, several existing group-based statistics to detect such improbable score patterns were investigated, along with the…

The booklet is part of a grade 10-12 social studies series produced for bilingual education. The series consists of six major thematic modules, with four to five booklets in each. The interdisciplinary modules are based on major ideas and designed to help students understand some major human problems and make sound, responsive decisions to improve…

This pamphlet presents brief reviews of 38 population education software and online systems currently available. It includes mathematical models, simulations, databases, problem-solving games, online systems, and associations. The review includes a description of the program, the level at which it is aimed, required computer hardware, the vendor's…

This report describes and evaluates the K-12 driver and traffic safety education program at the Des Moines (Iowa) public schools. Four perspectives are evaluated: context, input, process, and product. The school district's mission, the program's philosophy, and the supervisor's viewpoint are outlined. The current program and its course content is…
