The Effects of Concurrent Classroom and Home Instructional Video-Game Use on Student Achievement

ABSTRACT

This study focused on whether Internet use improves skills for practical use of information, which is termed information literacy in Japan. Data from Japanese elementary school children (n = 702) were analyzed in a two-wave panel study in order to estimate the causal relationship between Internet use and information literacy. Structural equation modeling was the specific technique applied in a cross-lagged effect model. Results of the analysis indicated that greater use of the Internet led to higher information literacy in the whole-scale measure of practical use of information, as well as in the subskill areas of collecting, judging, and expressing information.     

K-12 Mathematics and the Web

Abstract

The Web offers numerous learning resources and opportunities for K-12 mathematics education. This paper discusses those resources and opportunities. Discussion includes (a) asynchronous and synchronous communication tools, (b) the use of data sets to make connections between mathematics concepts and real-world applications, and (c) interactive environments that promote active thinking by allowing students to manipulate mathematical systems, observe patterns, form conjectures, and validate findings.     

Distance Education in the Rural K-12 Environment

Abstract

A small rural school in Idaho tried various forms of distance education to broaden the range of subjects offered to students. It gave up on satellite-based coursework because of high cost and synchronization problems. Correspondence courses solved the synchronization problem, but still required expensive adult supervision to keep students on task. IP-based videoconferencing appeared to promise lower costs and better synchronization, but in practice it proved to be difficult to implement and exhausting for course teachers. The school began to view videoconferencing in terms of its enrichment and collaboration values. The Internet, together with other distance education technologies, may one day erase the educational disadvantages of rural isolation. They also promise to make lifelong learning the expected norm.     

Untangling the Net

Abstract

The importance of computer training in social work education will continue to increase as the profession becomes more globalized and technological. It is the authors' premise that social work education must include the integration of training in computer technology. One resource available to educators is the Internet. The world wide web contains a vast amount of information on policy and social issues. This article discusses the use of web based learning exercises to simultaneously teach social policy and enhance student computer skills. Two learning exercises are presented which are designed for use in social work policy courses. The authors present their teaching experiences and provide suggestions on using this approach in the classroom environment. Information on resources and useful URL's for policy research is included in the discussion.

论后现代语境下的网络言论

作为信息传递最便捷的渠道,网络在展现强大的新闻整合能力之余,其言论在本质上与传统媒体划出一道明确的界限。在后现代语境中,网络言论与其他叙事文本一样都表现出某种后现代风格,但网络媒介立足于现代范式还是后现代范式成了一个问题。本文对后现代语境中网络言论风格阐述后认为,建立在格里芬后现代思想上的网络话语风格当是我们追求的目标。
