Several teachers from State College (Pennsylvania) Area School District became intrigued with helping their students better understand the science associated with a unit on air and aviation. In particular, they observed that students often encountered difficulty with abstract flight concepts, such as lift, thrust, and drag. Content issues became…

This study describes the usefulness of a simulation, MARRIAGE AND FAMILY, in helping newly arrived international students adjust to the academic demands of university life. It outlines various phases of the simulation. The narrative regarding its implementation in the classroom demonstrates how well many international students adapt to the value…

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

Case studies are an important vehicle for student learning in problem-based learning curricula and higher education. "WebCaseStudy.com" was designed to support student learning through case studies in a simulated community of practice. This paper reports on the process of capturing community of practice knowledge for case studies to…

Background: The current mode of stoichiometry instruction employs a passive pedagogy that consists of students reading, listening, watching, and memorizing disembodied facts, procedures, and principles in preparation for future application. But chemistry students are often subsequently unable to apply this stoichiometry knowledge in equilibrium…

In this paper we develop materials to address student interest in the Indian Ocean tsunami of December 2004. We discuss the physical characteristics of tsunamis and some of the specific data regarding the 2004 event. Finally, we create an easy-to-make tsunami tank to run simulations in the classroom. The simulations exhibit three dramatic…

This paper is a review of literature about the use of computer simulations in science education. This review examines types and examples of computer simulations. The literature review indicated that although computer simulations cannot replace science classroom and laboratory activities completely, they offer various advantages both for classroom…

This issue of the Emergency Response and Crisis Management (ERCM) Technical Assistance Center's "ERCMExpress" promotes emergency exercises as an effective way to validate school safety plans. Simulations of emergency situations, or emergency exercises, are integral to a sound school safety plan. They offer opportunities for district and schools to…

Two groups of three students with moderate mental retardation were instructed using group procedures to compare static picture and video prompting simulation strategies. An alternating treatments design was used to compare individual student task acquisition and maintenance performances of purchasing and banking skills. The results indicated that…

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris'…

This study examined 2- to 3-year-olds' ability to make a pretend-real distinction in the absence of content cues. Children watched two actors side by side. One was really eating, and the other was pretending to eat, but in neither case was information about content available. Following the displays, children were asked to retrieve the real food…

Structural equation models are widely appreciated in social-psychological research and other behavioral research to model relations between latent constructs and manifest variables and to control for measurement error. Most applications of SEMs are based on fully observed continuous normal data and models with a linear structural equation.…

The performance of methods for detecting publication bias in meta-analysis was evaluated using Monte Carlo methods. Four methods of bias detection were investigated: Begg's rank correlation, Egger's regression, funnel plot regression, and trim and fill. Five factors were included in the simulation design: number of primary studies in each…

This study explored teachers' pedagogical strategies for using multimedia simulation to structure and support secondary science teaching. Expertise was investigated across a range of classroom settings to analyse how specialist knowledge is situated within and adapted to the teaching and learning context. Analysis of data arising from 10 lesson…

The usefulness of assessing individual fit in latent growth curve models was examined. The study used simulated data based on an unconditional and a conditional latent growth curve model with a linear component and a small quadratic component and a linear model was fit to the data. Then the overall fit of linear and quadratic models to these data…
