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.

As China enters WTO, more college graduates with higher oral English proficiency are required. However, we learned that even students in some distinguished universities are lack of this ability. Based on her teaching experiences and the theory proposed by Krashen and some other well-know foreign languages teaching researchers, the author of this…

E-books are increasingly available from a variety of distributors and retailers, and work on a myriad of devices, but the majority remain simply digitized versions of print books. Some devices or platforms include…

The current investigation studied the effects of a computer software program of the oral reading fluency and comprehension of eight, first grade students. These students were identified as being either "at-risk" or "some-risk" for reading failure on the DIBELS oral reading fluency winter benchmark assessment. A multiple probe…

This study was designed to evaluate the effects of the proprietary science education software, "Conversionoes," on students' conceptual and visual understanding of dimensional analysis. The participants in the study were high school general chemistry students enrolled in two public high schools with different demographics (School A and…

A postal survey of high school astronomy teachers strongly confirms many results of an earlier electronic survey. Additional and new results include a measure of the level of inquiry (more structured inquiry and teacher-led) in the classroom as well as data showing that more emphasis is given to traditional topics than to contemporary astronomy…

This paper is a report of the replication of a seminal study on cognitive presence in computer mediated conferencing (CMC) by Garrison, Anderson, and Archer (2001). A comparison of cognitive presence coding by three different researchers is also demonstrated. The study re-ignites debates about what constitutes the segment of CMC data to be coded…

As part of a curriculum development project entitled Crossing Boundaries, these authors designed an inquiry-based activity that introduces students to landscape change and potential impacts on associated biological communities. Using pairs of current and historical satellite images, students explore landscape change in a variety of U.S. and…

Purpose: Self- and peer assessment has proved effective in promoting the development of teamwork and other professional skills in undergraduate students. However, in previous research approximately 30 percent of students reported that its use produced no perceived improvement in their teamwork experience. It was hypothesised that a significant…

The number of students studying university mathematics in the UK has been increasing gradually and linearly since 2002. At the University of Portsmouth, number of students studying mathematics doubled from 30 to 60 between 2002 and 2007, then increased by 240% in just 1 year to over 140 in 2008. This article explains how learning technology has…

This study compared the effectiveness of self-, other-, and subjective-video models on teaching daily living skills to three individuals with developmental disabilities. Results indicated that all conditions were effective in promoting independent correct responding in both instructional and generalization settings and that the effects maintained…
