One of the most vexing issues faced by experimental social psychologists is the creation and subsequent maintenance of a laboratory. Consequently, well-equipped experimental sociology laboratories are most likely to be found in institutions with larger resources and an established history of experimental research. Smaller institutions or those…

A common activity--having students collect data to measure the radius and circumference of circular objects--can be given a new twist. These data can be viewed virtually using technology. A dynamic geometry environment coupled with the powerful capabilities of a spreadsheet can greatly enhance student learning. The activity in this article…

Radford University was recently configured with a campus-wide wireless local area network. Using these new capabilities, a classroom-based Honors section of Concepts of Biology was conducted solely using electronic technologies (paper was never transferred from professor to student). To accomplish this, students used common software and freeware.…

Models in Software Engineering are considered as abstract representations of software systems. Models highlight relevant details for a certain purpose, whereas irrelevant ones are hidden. Models are supposed to make system comprehension easier by reducing complexity. Therefore, models should play a key role in education, since they would ease the…

Differential item functioning (DIF) occurs when an item on a test, questionnaire, or interview has different measurement properties for one group of people versus another, irrespective of true group-mean differences on the constructs being measured. This article is focused on item response theory based likelihood ratio testing for DIF (IRT-LR or…

EDUCAUSE, a nonprofit association dedicated to advancing higher education by promoting the efficient and effective use of information technology, recently released the annual "ECAR Study of Undergraduate Students and Information Technology" (Smith and Caruso 2010). The purpose of this annual study is to illuminate the roles technology plays in the…

Example programs play an important role in the teaching and learning of programming. Students as well as teachers rank examples as the most important resources for learning to program. Example programs work as role models and must therefore always be consistent with the principles and rules we are teaching. However, it is difficult to find or…

Objective: To explore children's motivations for and perceived benefits and barriers to nutrition research participation. To explore children's perspectives on how to improve the research experience. Design: Seven focus group sessions were conducted during March 2008 with research participants from a trial that examined the effects of pre-exercise…

The purpose of this study was to examine second language learners' learning achievement and attitudes toward two different types of dual coding designs (text group: image plus on-screen text versus narration group: image plus narration) in Chinese character acquisition. A total of 66 college students who did not have prior knowledge of the Chinese…

Fierce competition, globalization, and technology innovation have forced software companies to search for new ways to improve competitive advantage. Web-based learning is increasingly being used by software companies as an emergent approach for enhancing the skills of knowledge workers. However, the current practice of Web-based learning is…

Assessment is an essential element in learning processes. It is therefore not unsurprising that almost all learning management systems (LMSs) offer support for assessment, e.g., for the creation, execution, and evaluation of multiple choice tests. We have designed and implemented generic support for assessment that is based on assignments that…

A high failure rate at first year physics is often attributed to the lack of readiness of high school students to pursue such studies. This research explores this issue and reports on the perceptions of five physics lecturers at a South African university on the preparedness of high school students for first year physics. Qualitative data was…

Students have problems with understanding, using and interpreting graphs. In order to improve the students' skills for working with graphs, we propose Manual Video Measurement (MVM). In this paper, the MVM method is explained and its accuracy is tested. The comparison with the standardized video data software shows that its accuracy is comparable…

This study examines the reasons for using or not using interactive whiteboards (IWBs) by elementary school mathematics and science teachers in Taiwan. It also considers whether there were any significant differences in the reasons according to teaching subjects, teacher gender, and teaching experience. The survey was developed based on an overview…

Students with emotional disturbance exhibit difficulty interpreting and responding appropriately to social situations occurring in the community, home, and school. Interactive multimedia instruction has advanced to the degree that it is possible to create learning environments that encourage active problem solving and knowledge construction. This…
