Studying and evaluating real experiences that promote active and collaborative learning is a crucial field in CSCL. Major issues that remain unsolved deal with the merging of qualitative and quantitative methods and data, especially in educational settings that involve both physical and computer-supported collaboration. In this paper we present a…

Corporations employ data mining to analyze operations, find trends in recorded information, and look for new opportunities. Libraries are no different. Librarians manage large stores of data--about collections and usage, for example--and they also want to analyze this data to serve their users better. Analysts use data mining to query a data…

This case study covers several exploratory data analysis ideas, the histogram and boxplot, kernel density estimates, the recently introduced bagplot--a two-dimensional extension of the boxplot--as well as the violin plot, which combines a boxplot with a density shape plot. We apply these ideas and demonstrate how to interpret the output from these…

As the numbers of students who earn the general educational development (GED) high school equivalency diploma increase, so too does the presence of GED credential holders on college campuses. Yet in large universities, they make up a relatively small demographic group whose advising needs may go unnoticed. In this article, we describe a series of…

This essay has its origin in a project on the globalization of science that rediscovered the wisdom of past research practices through the technology of the future. The main argument of this essay is that a convergence of digital video technologies with practices of social surveillance portends a methodological shift towards a new variety of…

The purpose of this study was to examine how incorporating technology into teaching methods (including the phases of organizing video conferencing sessions) promotes college students' construction of knowledge. Video conferencing technology via the Internet afforded an enriched environment in which students interacted with educators at different…

Data exists in the context of a community that drives data collection and use. The effective use of data can help principals make informed decisions about their policies, practices, and procedures to improve student achievement. The more systematic and thorough principals are about bringing data to the table when making decisions, the more…

Teachers know that a constructivist approach involving project-based, student-centered activities can result in students taking an active role in their own learning and engaging in thought-provoking challenges. When accomplished with collaborative activities, students develop skills that will serve them well in the future in any group project.…

Although many critics are reluctant to accept the trustworthiness of qualitative research, frameworks for ensuring rigour in this form of work have been in existence for many years. Guba's constructs, in particular, have won considerable favour and form the focus of this paper. Here researchers seek to satisfy four criteria. In addressing…

Increasingly national statistical agencies are being called upon to provide high quality data on a regular basis, to be used by governments for evidence-based policy development. Poverty Reduction Strategy Papers (PRSPs) give impetus to this, and bring a prerequisite for comprehensive "poverty diagnosis." Often the data that are required…

Background: Despite recent interest in relationships between maternal gesture and speech and communicative development in typically developing (TD) children, little work has examined either speech or gesture in mothers of children with Down's syndrome (DS). Aims: To compare aspects of speech and gesture production by mothers of children with DS…

Knowledge, especially tacit knowledge, has gained more and more attention in recent years. The author claims that, with the development of information technology, more knowledge sharing takes place online rather than face-to-face. The purpose of this study is to explore how tacit knowledge is externalized in online environments. To answer this…

The present study represents an evaluation of the implementation of the integration of the American Sociological Association's (ASA) Integrating Data Analysis Project into 2 online offerings of an undergraduate sociology of aging course. This program was developed in response to concerns that students did not understand the complex relationships…

Reform initiatives such as "Science for All Americans" (AAA, 1989) and "National Science Education Standards" (NRC, 1996) argue for making science accessible to all children regardless of age, sex, cultural and/or ethic background, and disabilities. One of the most popular and prevailing phrases highlighting science education reform in the last…

The American Recovery and Reinvestment Act (ARRA) provides several funding opportunities that can assist states in designing, developing, and implementing statewide education longitudinal data systems. These new and enhanced information systems will enable states to track student progress within and across the secondary and postsecondary education…
