The aim of this study was to assess the learning effectiveness and motivational appeal of a computer game for learning computer memory concepts, which was designed according to the curricular objectives and the subject matter of the Greek high school Computer Science (CS) curriculum, as compared to a similar application, encompassing identical…

Despite a growing development of virtual laboratories which use the advantages of multimedia and Internet for distance education, learning by means of such tutorial tools would be more effective if they were specifically tailored to each student needs. The virtual teaching process would be well adapted if an artificial tutor can identify the…

This report presents the results of a research and development effort for SpeechRater? Version 1.0 (v1.0), an automated scoring system for the spontaneous speech of English language learners used operationally in the Test of English as a Foreign Language™ (TOEFL®) Practice Online assessment (TPO). The report includes a summary of the validity…

Computer-supported discursive learning (CSDL) systems for the support of asynchronous discursive learning need to fulfill specific socio-technical conditions. To understand these conditions, we employed design experiments combining aspects of communication theory, empirical findings, and continuous improvement of the investigated prototypes. Our…

The word "architect" calls to mind a designer of buildings. An architect's job is to develop a structure to fit the client's needs, some of which are conflicting (or seem to be). When it comes to designing a campus network, IT infrastructure architects have a similar function. Like a building architect, an IT architect must develop a…

With the advent of web-based programs that automate the scoring of exercises, materials are now being developed from the outset with the capabilities of the web in mind. Materials developed without consideration of the web's capabilities, on the other hand, must be retrofitted. Texts that are retrofitted to the web have the advantage of being…

In this paper, we propose three different ways of using IMS Learning Design to support online adaptive learning modules that include educational videogames. The first approach relies on IMS LD to support adaptation procedures where the educational games are considered as Learning Objects. These games can be included instead of traditional content…

Given the recent spate of library system vendor acquisitions and consolidations, integrated library system (ILS) migrations have become a hot topic again. Although ILS migrations happen all the time, they tend to be cyclical in nature. Today, people are thinking broadly about what options might be available to them. These include changing vendors,…

Recent research on annotation interfaces provides provocative evidence that anchored, annotation-based discussion environments may lead to better conversations about a text. However, annotation interfaces raise complicated tradeoffs regarding screen real estate and positioning. It is argued that solving this screen real estate problem requires…

Course management systems (CMSs) are software systems designed to manage course content and course activities. These tools integrate technological and pedagogical features into a web-based system that allows instructors, even those who are unfamiliar with web-based technologies, to design, deliver, and manage an online course. However, CMSs have…

Distance learning is appealing to small business owners, employees, municipalities, state establishments, non-governmental organizations. Distance-learning are ideal for people who have a full-time job or other commitments, who can't take time off to study full time. This might be a professional who needs to update his knowledge or skills, or a…

In the early 1990s, numerous academic libraries adopted the web as a communication tool with users. The literature on academic library websites includes research on both design and navigation. Early studies typically focused on design characteristics, since websites initially merely provided information on the services and collections available in…

This paper will present a review of design-based research conducted over the past 10 years that has modeled and promoted students' reasoning, conceptual change and argumentative dialogue processes and practices through designing a number of digital dialogue games. This line of work was inspired by some challenges and insights that emerged during…

Despite the problems presented by lexical errors in second language (L2) communication, most computer assisted language learning (CALL) programs tend to focus on the acquisition of grammar points rather than on the development of the L2 lexicon. In addition, CALL vocabulary tasks are typically limited in scope and mechanical in nature, covering…

The IMS Learning Design specification aims at capturing the complete learning flow of courses, without being restricted to a particular pedagogical model. Such flow description for a course, called a Unit of Learning, must be able to be reproduced in different systems using a so called run-time environment. In the last few years there has been…
