Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…

When a college instructor goes out of town and must miss a lecture, the standard options are to cancel the class meeting or to enlist a colleague to fill in. In the former case a teaching opportunity is lost; in the latter the substitute may not lead the class in the same way as the instructor. Some students routinely skip lectures by a guest…

Purpose: Playing back recorded lectures on handheld devices offers interesting perspectives for learning, but suffers from small screen sizes. The purpose of this paper is to propose several semi-automatic post-processing steps in order to improve usability by providing a better readability and additional navigation functionality.…

This paper describes a study of online discussion forums as tools for promoting higher-order thinking. The study was carried out in a women's university in the United Arab Emirates. Data, in the form of online discussion forum transcripts, were collected over a 20-week semester and were analysed according to a model developed by Garrison,…

Emerging from recent mobile technologies, mobile learning, or m-learning, is beginning to offer "stunning new technical capabilities" in education (DiGiano et al., 2003). This new genre of learning is viewed as a revolutionary stage in educational technology. However, ubiquitous computing technologies have given rise to several issues. This…

This paper discusses Svetovid, cross-platform software that helps instructors to assess the amount of effort put into practical exercises and exams in courses related to computer programming. The software was developed as an attempt at solving problems associated with practical exercises and exams. This paper discusses the design and use of…

Drawing on Archer's perspectives on the agency/structure relationship, this paper explains situations where students in varied, challenging circumstances find ways to negotiate difficult conditions. It reports on a 2007 study undertaken through a survey at three quite different universities in three South African provinces, addressing…

In this paper, a simple MATLAB-based PC program that enables the computer to function as a replacement for the electronic scalar-counter system associated with a Geiger-Muller (GM) tube is described. The program utilizes the ability of MATLAB to acquire data directly from the computer sound card. The signal from the GM tube is applied to the…

By studying Antarctica via satellite and through ground-truthing research, we can learn where the ice is melting and why. The Landsat Image Mosaic of Antarctica (LIMA), a new and cutting-edge way for scientists, researchers, educators, students, and the public to look at Antarctica, supports this research and allows for unprecedented views of our…

This study surveyed 366 Valparaiso University freshmen to discover their feelings about librarians using Facebook and MySpace as outreach tools. The vast majority of respondents had online social network profiles. Most indicated that they would be accepting of library contact through those Web sites, but a sizable minority reacted negatively to…

Discourse about the scholarship of teaching and learning appears to represent some views about higher education more than others. For example, disciplinary perspectives have been acknowledged, and ideas from critical theory and phenomenography have been presented, with the role of reflection receiving considerable attention. While approaches to…

An interactive classroom communication system (ICCS) involves the use of remote devices that permit all students in a class to respond to multiple choice questions displayed on a LCD projector. After responses are clicked in, the results are instantly aggregated and displayed in chart form. The purpose of this study was to examine gender…

Partly owing to the status of podcasting as a buzzword and subject of much recent media attention, educational technology researchers and practitioners have been using the term very loosely. Few studies have examined student perceptions and uptake of "podcasting" in the true sense of the word, whereby a syndication protocol such as Really Simple…

The integration of technology by K-12 teachers was promoted to aid the shift to a more student-centered classroom (e.g., Roblyer, M. D., & Edwards, J. (2000). "Integrating educational technology into teaching" (2nd ed.). Upper Saddle River, NJ: Merrill). However, growth in the power of and access to technology in schools has not been accompanied…

Digital tools, such as blogs and wikis, now make it easy for educators to embrace continual learning. Thousands of accomplished educators are now writing blogs in which they reflect on instruction, challenge assumptions, question policies, offer advice, design solutions, and learn together. All this collective knowledge is readily available for…
