The challenge of the semantic web is the provision of distributed information with well-defined meaning, understandable for different parties. Particularly, applications should be able to provide individually optimized access to information by taking the individual needs and requirements of the users into account. In this paper we propose a…

The U.S. Department of Education's "back to the basics" thrust of the 1980s took a terrible toll on enrollments for those teaching in the "practical arts." So, in the face of declining enrollments, angry employers wanting more program graduates, and a concerned advisory council, technology teachers must go on television and express their…

This paper introduces the language associated with a polygon microworld called Polygon R&D, which has the mathematical crispness of Logo and has the discreteness and simplicity of a Turing machine. In this microworld, polygons serve two purposes: as agents (similar to the turtles in Logo), and as data (landmarks in the plane). Programming the…

Today's post-secondary students are technologically savvy and they expect faculty to use myriad web technologies for course delivery. This includes taking advantage of email, course web sites, and online learning communities. However, expectations now also include RSS, blogs, web- and pod-casting, extending the classroom experience to provide…

This paper analyses the teaching and learning of computing in a Web-conferencing environment. A discourse analysis of three introductory programming learning episodes is presented to demonstrate issues and effects that arise when teaching computing using such an approach. The subject of discussion, the interactive nature of discussion and any…

In teacher education, electronic portfolios provide an authentic form of assessment documenting students' personal and professional growth. Using the engineered-based system, College LiveText, and an off-the-shelf general tool, HyperStudio, pre-service teachers constructed e-portfolios as part of their teacher preparation requirements. This case…

This article provides an analysis of student responses to an exercise used in a computer ethics and a software engineering course to raise awareness of issues related to hiring, including issues of professional responsibility and diversity. Students from two different universities were asked to evaluate four candidates for two positions in a…

Noting that the social and emotional experiences of American children today often heavily involve electronic media, Barbara Wilson takes a close look at how exposure to screen media affects children's well-being and development. She concludes that media influence on children depends more on the type of content that children find attractive than on…

This paper reports the results of a study of the relationship of robotics activity to the use of science literacy skills and the development of systems understanding in middle school students. Twenty-six 11-12-year-olds (22 males and 4 females) attending an intensive robotics course offered at a summer camp for academically advanced students…

The Computing Curricula (2005) place Information Systems (IS) at the intersection of exact sciences (e.g. General Systems Theory), technology (e.g. Computer Science), and behavioral sciences (e.g. Sociology). This presents particular challenges for teaching and learning, as future IS professionals need to be equipped with a wide range of…

An ideal time to start health promotion education is during the elementary years. However, over the last several years, many elementary schools have eliminated formal health education from their curriculum, subsequently integrating health education components into existing classroom content. The "I Feel Good!" radio broadcast is an…

The education industry has obviously been influenced by the Internet revolution. Teaching and learning methods have changed significantly since the coming of the Web and it is very likely they will keep evolving many years to come thanks to it. A good example of this changing reality is the spectacular development of e-Learning. In a more…

The Federal Communications Commission is currently considering modifying or eliminating existing media ownership rules. Children's advocates are concerned that any changes to these rules could negatively affect the already limited amount and types of programming available for children. Children Now conducted the first study to examine the…

It is not surprising that the interactivity affects radio and its applications. Besides, after radio began its first broadcasting, new inventions affected its development two ways: 1) the first one was the technological developments of sciences. For instance, the invention of transistors made it possible to create very small radio machines, and…

In a fundamental computer-programming course, such as CSE101, questions about how to evaluate an arithmetic expression are frequently used to check if our students know the rules of precedence. The author uses two of our final examination questions to show that more knowledge of computer science is needed to answer them correctly. Furthermore,…
