Although usability evaluations have been focused on assessing different contexts of use, no proper specifications have been addressed towards the particular environment of academic websites in the Spanish-speaking context of use. Considering that this context involves hundreds of millions of potential users, the AIPO Association is running the UsabAIPO Project. The ultimate goal is to promote a...

Multimedia courseware has been widely used after the introduction of smart school project. This paper describes the development of the interactive courseware with embedment of Pedagogical Agents, Games Based Learning and Blended Learning elements. The focus of the courseware is Loci in Two Dimensions since most of the students have difficulties in understanding this topic. The combination of th...

This paper describes evaluating interactive entertainment by understanding embodied learning in games, which is a perspective that situates the learning that a player must go through to play a game in a skill-based environment. Our goal was to arrive at a tool for designers to improve learnability from this perspective. To study embodied learning, we use the concept of breakdown, which happens ...

Usability evaluation techniques such as user-observations, cognitive walkthroughs, or heuristic evaluations can be applied to evaluate the usability of multimedia interfaces of computer systems. Although user observations involve observing end-users or representative users interacting with the system these evaluations are limited in the amount of information they can provide. For example, if th...

The paper specifies the development of synthetic laboratories to facilitate collaborative learning. We evaluated the usability of virtual labs that comprise media tools and complex computer simulations. The goal was to quantify impact of interactive 3D visualization on students during their conduct of simulated physical experiments at the same time from different places. Students experimented a...

Research on heuristic evaluation in recent years has focused on improving its effectiveness and efficiency with respect to user testing. The aim of this paper is to refine a research agenda for comparing and contrasting evaluation methods. To reach this goal, a framework is presented to evaluate the effectiveness of different types of support for structured usability problem reporting. This pap...

In this study we show the influence of references on trust in information. We changed the contents of reference lists of Wikipedia articles in such a way that the new references were no longer in any sense related to the topic of the article. Furthermore, the length of the reference list was varied. College students were asked to evaluate the credibility of these articles. Only 6 out of 23 stud...

This paper reports ongoing research concerning issues in the development of an intelligent debating system. The motivation behind such development is that it can be used to develop students’ reasoning and debating skills. We consider the assessment of the underlying dialogue model of the system, means of design and implementation of a computational prototype to facilitate human computer debate,...

1 Authors current address: University of Virginia’s College at Wise, Wise, VA 24293 Heuristic evaluation method comparison is important for developing new heuristic sets, to ensure effectiveness and utility. However, comparing different sets of heuristics requires a common baseline upon which a comparison can be made, usually some set of usability problems from a particular interface. This is o...

The teaching and learning of a complex section in Theoretical Computer Science 1 in a distanceeducation context at the University of South Africa (UNISA) has been enhanced by a supplementary e-learning application called Relations, which interactively teaches mathematical skills in a cognitive domain. It has tutorial and practice functionality in a classic computer-aided instruction (CAI) style...
