The extensification activities of Education Informatics Network use in Turkey are in progress. The use and preferability of this education portal by teachers and students depend on various factors. One of these factors is usability. The purpose of this research is to make the usability analysis of the Education Informatics Network from the…

We applied a user interface (UI) design approach based on a constructivist perspective for web-based learning that conceptualizes interactions between learners and websites as conversations. Hyperlinks on the UI of a distributed interactive learning environment were treated as invitations for interaction to encourage learners' active exploration.…

A "user interface" is the part of an interactive system that bridges the user and the underlying functionality of the system. But people sometimes forget that the best interfaces will provide a platform to optimize the users' interactions so that they support and extend the users' activities in effective, useful, and usable ways. To look at it…

Focuses on human behavior in the information-seeking process, and identifies behaviors influencing the design of information retrieval system interfaces. Discusses the principles of saturation, concreteness, least resistance, familiarity, stimulation, certainty, simplicity, and following-form. (PEN)

Reviews several mechanisms to support navigation in hypertext following a brief discussion of the phenomena of disorientation in hyperspace. Categorizes ways to support navigation in terms of the following: solutions regarding the tools to support navigation; solutions regarding interface and navigation metaphors; and solutions regarding hardware…

This research examined the communication process between users and online catalogs by gathering empirical data about user performance on different types of online catalogs. An experiment was designed to test whether content and layout of bibliographic displays influenced effectiveness of the interface between online catalogs and users. Data are…

Explores the concepts of interaction and interactivity presented in different theoretical models in the fields of human-computer interaction (HCI) and information-seeking/searching behavior, and relates these to information retrieval (IR) research. Suggests that interaction in HCI is primarily concerned with establishing a user/system dialogue at…

Presents a stratified model of information retrieval interaction that views interaction as a dialog between participants (user and computer) through an interface. Discusses traditional and interaction models, and extension to relevance, user modeling, search term selection, and types of feedback in information retrieval. (AEF)

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
