Multimedia is a mixture of text, audio, video, graphics, and images. Research studies have shown that higher levels of learning occur when students are presented information via multimedia rather than a single medium. The actual mechanics of inserting multimedia components into a file varies from application to application. For example, to insert…

The Moodle course management system is an open source system that educators can use to create online courses. Begun in 1999, the Moodle community has now grown so that by early June 2005 there were about 3,500 Moodle sites in more than 100 countries (and that counts only registered users). To use Moodle, one first needs to install it on a Web…

The goal of this paper is to provide a tutorial introduction to the topic of edge detection of the tongue from ultrasound scans for researchers in speech science and phonetics. The method introduced here is Active Contours (also called snakes), a method for searching for an edge, assuming that it is a smooth curve in the image data. The advantage…

An Excel file that performs self-consistent field (SCF) calculations for the two-electron atoms is described. It is readily constructed and is relatively simple to use, providing a visual demonstration of how the self-consistent field (SCF) procedure is applied and what issues are involved.

This article outlines how a web based video conferencing system (Marratech) was used in a graduate online counselor education course as part of a blended online graduate degree in Counseling. Since the course is open to students from around North America, a variety of e-delivery methods of instruction is significant to the program's success. A…

The 2008 CASAS "Bibliography of Citizenship Materials" lists available instructional resources for citizenship education. It focuses on materials appropriate for preparing people for the naturalization process and the standardized citizenship examination. Resources include textbooks, audio materials, software and Videos/DVDs. The bibliography also…

The author has previously reported on principles of diffusion of innovations, the processes by which new technologies become popularly adopted, specifically in relation to anatomy and education. In presentations on adopting handheld computers [personal digital assistants (PDAs)] and personal media players for health sciences education, particular…

Purpose: The purpose of this paper is to investigate the effect of an embedded pedagogical agent into a tutorial on achievement. Design/methodology/approach: Research methodology is designed according to the post test control group model in which the experimental group (69 students) was exposed to a tutorial with an embedded pedagogical agent;…

In a study of the types of problems encountered by students that led them to seek assistance, Robins et al. [2006] found that the most common problems were related to trivial mechanics. The students in this study worked by themselves on their programming exercises. This article discusses a replication of the Robins et al. study in which the…

Pair programming, as part of the Agile Development process, has noted benefits in professional software development scenarios. These successes have led to a rise in use of pair programming in educational settings, particularly in Computer Science 1 (CS1). Specifically, McDowell et al. [2006] has shown that students using pair programming in CS1 do…

This article describes the evolution of the development of a framework for e-learning to reconsider e-learning in relation to the cooperative work framework, identifying critical weaknesses in the fundamental nature of e-learning and its consequent propensity for failure. (Contains 4 figures and 2 notes.)

The Web 2.0 "buzz" starts with new technologies such as virtual worlds, cell phones and handheld devices that offer 24/7 web access, tagging, social networks, and blogs and brings together various web capabilities in unique combinations. Web 2.0, however, is about much more than the technology--it is about a change in focus to participation, user…

Representatives from more than 20 institutions making up a research and teaching network met to discuss and investigate a web application designed to promote knowledge sharing and understanding. The web application, called Fieldtrip, enables students, professors and researchers to virtually share their experiences and findings from real field…

Interactive applets have the ability to enhance statistics teaching by providing multiple representations of new concepts and by facilitating experimentation. I introduce two applets that have been developed as aids in illustrating ideas relevant to hypothesis testing and describe how I have used these in my classes. (Contains 4 figures.)

Understanding the concept of the sampling distribution of a statistic is essential for the understanding of inferential procedures. Unfortunately, this topic proves to be a stumbling block for students in introductory statistics classes. In efforts to aid students in their understanding of this concept, alternatives to a lecture-based mode of…
