Measuring and comparing the reliability of the structured walkthrough evaluation method with novices and experts

Effective evaluation of websites for accessibility remains problematic. Automated evaluation tools still require a significant manual element. There is also a significant expertise and evaluator effect. The Structured Walkthrough method is the translation of a manual, expert accessibility evaluation process adapted for use by novices. The method is embedded in the Accessibility Evaluation Assistant (AEA), a web accessibility knowledge management tool. Previous trials examined the pedagogical potential of the tool when incorporated into an undergraduate computing curriculum. The results of the evaluations carried out by novices yielded promising, consistent levels of validity and reliability. This paper presents the results of an empirical study that compares the reliability of accessibility evaluations produced by two groups (novices and experts). The main results of this study indicate that overall reliability of expert evaluations was 76% compared to 65% for evaluations produced by novices. The potential of the Structured Walkthrough method as a useful and viable tool for expert evaluators is also examined. Copyright 2014 ACM

CHANGING LEARNING ENVIRONMENT THROUGH TECHNOLOGY

Evolution of E-learning phenomenon exceeded all expectations in recent years.As a result of development of IT&C technologies and, on the other hand, due to support decision-makers at European level, the assimilation of virtual learning platforms in schools and universities hasbecome a normal phenomenon.The E-learning 2.0 concept seeks to revolutionize traditional learning methods and requires majorchanges in the perception of the educational process of teaching and learning.This article tries to create an overview of the main development directions and emphasizes the impactthat computer-assisted instruction technologies have on teaching and learning methods, with a directconnection to distance learning and blended learning concepts. Also, we have tried to open aperspective on the concept of e-Assessment and related technologiese-learning 2.0, computer based training, e-assessment, blended learning, distance learning

Educational Uses of Augmented Reality (AR): Experiences in Educational Science

Augmented Reality (AR) is an emerging technology that is gaining greater influence on teaching every day. AR, together with mobile technology, is defined as one of the most efficient pairs for supporting significant and ubiquitous learning. Purpose of the study: the Instructional Material Motivational Survey (IMMS), by Keller, was used to determine the degree of motivation possessed by the Pedagogy students on the utilization of the notes enriched with AR in the classroom, available for their didactic use through mobile devices. Methods: through an app designed for the courses Education Technology (ET) and Information and Communication Technologies (ICT) Applied to Education, the motivation gained when participating in this experience, and how it influences the improvement of academic performance, was evaluated. Results and conclusions: the most notable main result was finding a strong relationship between the motivation of the students when using the enriched notes and the increase of performance in the academic subject where it was used. Likewise, it was proved that the use of Augmented Reality benefited the learning process itself
