A comprehensive project in which the students use computational chemistry to investigate a larger chlorine oxide, Cl2O4 is described. The students start the project by reading a scenario and then follow a series of hyperlinks to develop, along with their colleagues, a better understanding of the implications of the presence of Cl2O4 in the…

Computers were invented to help mathematicians perform long and complicated calculations more efficiently. By the time that a computing area became a familiar space in primary and secondary schools, the initial motivation for computer use had been submerged in the many other functions that modern computers now accomplish. Not only the mathematics…

In selecting a Claude Bernard Distinguished Lecturer, the Teaching Section looks for an individual who has made major contributions to physiology education. Dr. Harold Modell has certainly earned this honor. Harold has an undergraduate degree from the University of Minnesota, a Masters in biomedical engineering from Iowa State, and, continuing the…

There has been much interest in using software tools to scaffold learners in complex tasks, that is, to provide supports that enable students to deal with more complex content and skill demands than they could otherwise handle. Many different approaches to scaffolding techniques have been presented in a broad range of software tools. I argue that…

With gym time getting squeezed out by standardized tests and extracurriculars, schools are beginning to digitize physical education. This alternative method is first being offered by Minneapolis public schools in spring of 2005. In digital physical education, students can perform physical activities like they would in a traditional PE class but…

While critics draw important attention to worrisome aspects of digital cultures, they may be missing a much larger point about how young people live in a digital world, how they create and re-create themselves and their identities in ways that are remarkably foreign to others "digital immigrants". In this article, "digital immigrants" refers to…

Explanations are essential in the teaching process. Tracers are one possibility to provide students with explanations in an intelligent tutoring system. Their development can be divided into four steps: (a) the definition of the trace model; (b) the extraction of the information from this model; (c) the analysis and abstraction of the extracted…

This case study addresses the use of the "anchored instruction approach" to restructure educational computing courses to enhance future teachers' learning of technology applications in the classroom. A cohort group of 22 preservice teachers from a typical teacher education institution in Southeastern Ohio was involved in the study. The…

There has been considerable emphasis on the availability and reuse of learning content in recent years. Since 2000, the ADL initiative has refined the recommendations contained in the SCORM documents through progressive stages represented in the SCORM 1.0, 1.1, 1.2 and 1.3 documents. Fundamental to SCORM is the notion of the Shareable Content…

A frequent concern raised by distance educators is that e-learning takes more time to facilitate than traditional classroom instruction. The simple fact that it takes more time to read and write than to speak and listen warrants consideration. To establish viable e-learning programs, we need to optimize the amount of time educators spend online.…

Teaching social studies with historical maps allows teachers and students not only to examine a historical event or place, but to analyze the story behind the map. Historical maps can provide insight into the people and cultures of earlier times. Studying these historic maps may help students challenge the notion that people of earlier time…

The purpose of this study was to measure the effectiveness of an educational technology training workshop. The study investigated the attitudes of the participating school principals toward the use of technology in their schools and their willingness to advocate and support its use after attending the workshop. Also it investigated the advantages…

The purpose of this study was to examine the effects of teacher mediation on the mathematics learning of kindergarten students in a computer-assisted learning environment. A sample of 26 students was randomly selected and assigned into experimental and control groups. The experimental group was mediated by a teacher during the computer-assisted…

Helping prospective teachers become more knowledgeable and skilled in the use of technology in education is an important goal of today's teacher preparation programs. This article reports the results of a survey, "Pre-service Teacher Technology Survey: technology usage and needs of science educators", that determined pre-service science…

Modeling has been shown to correct weaknesses of traditional instruction by engaging students in the design of physical models to describe, explain, and predict phenomena. Although the modeling method can be used without computers, the use of computers allows students to study problems that are difficult and time consuming, to visualize their…
