This work designs and implements a virtual digital signal processing laboratory, VDSPL. VDSPL consists of four parts: mobile agent execution environments, mobile agents, DSP development software, and DSP experimental platforms. The network capability of VDSPL is created by using mobile agent and wrapper techniques without modifying the source code…

Mobile computing devices are increasingly finding a place in universities, putting the pressure on teacher education to consider how best to incorporate the use of these technologies. At the same time there is pressure from the requirement for teacher education students to develop skills and experience in using digital technologies to support…

It is by now well established that telecollaborative exchanges frequently end in "failed communication" and do not automatically bring about successful negotiation of meaning between the learners. Instead, the intended pedagogic and linguistic aims of online interaction are repeatedly missed, and projects may end in low levels of participation,…

Sixty-eight college students enrolled in a French course listened to a multimedia-based French passage in one of four groups to which they were randomly assigned: the listening text (a) alone, with no annotations; (b) in pairs, with no annotations; (c) alone, with written and pictorial annotations; and (d) in pairs, with written and pictorial…

In higher education, online discussions are an integral part of collaborative based e-Learning systems. However, there can be problems associated with current online discussion models. For example, it can be easy to set open-ended discussions which attract little participation and assessing contributions can be difficult or time-consuming.…

Selecting elite students out of a huge collective is a difficult task. The main problem is to provide automated processes to reduce human work. ECMS (Educational Contest Management System) is an online tool approach to help--fully or partly automated--with the task of selecting such elite students out of a mass of candidates. International tests…

The rapid growth of online learning has mandated the development of faculty evaluation models geared specifically toward the unique demands of the online classroom. With a foundation in the best practices of online learning, adapted to meet the dynamics of a growing online program, the Online Instructor Evaluation System created at Park University…

Online learning holds promise for providing new educational opportunities to a wide range of students across the country. The rapid expansion of K-12 online learning, however, threatens to outpace the development of appropriate state-level policies that serve to fulfill the promise. As the National Association of State Boards of Education warned…

Online education, supported by online resources such as e-mail, chat rooms, and Web-based instruction, is a rapidly growing area of tertiary/higher education that has been facilitated by increased usage of home computers and advances in the development of user-friendly interfaces. A range of positive outcomes has accompanied the growth of online…

This paper reports on the learning experiences of a small group (n = 13) of teaching assistants who volunteered to participate in a pilot online Foundation Degree module. As part of the evaluation methodology, participating students were randomly assigned into two groups, with each group having clearly defined but different types of tutorial…

A bibliometric approach is used not only to sketch out the development of CALL during the last 25 years, but also to assess the contribution of educational technology to 21st century foreign-language teaching and learning. This study is based on the six instalments of the author's International (and multilingual) Bibliography of Computer Assisted…

Concept maps are widely used in education, and have been acclaimed for their excellent results. For efficiently using concept maps in education, computer-based concept mapping systems have been developed. However these computer-based concept mapping systems are limited in their assessment algorithms. The assessment takes only concept nodes as the…

This paper is a consideration of the issues associated with the infrastructural aspects, pedagogic considerations and the need to associate the usefulness of technology to enhance the learning experience. This technological path will potentially enhance the learning process, not replace the lecturer or tutor. For lecturers and students, the…

While the concepts and principles associated with learner autonomy underpin a broad range of CALL applications and research projects, current debates and research paradigms in CALL do not provide adequate tools and models to investigate in depth the relationship between CALL and the development of learner autonomy. This paper explores the…

This paper introduces the Quail Model, a device for the classification and visualisation of learning goals. The model is a communication tool that can smoothen the discussion within a course design team, support shared understanding, and improve decision making. Its theoretical background mingles contributions from instructional design (Bloom,…
