Evaluation of Interactive Learning Materials for Universal Design: Case of GeoGebra in Norwegian High Schools
MetadataVis full innførsel
The popularity of interactive learning materials is increasing in the field of education. In the field of mathematics, the GeoGebra online web application has become the part of curriculum in the higher secondary education in many countries. In case of Norway, GeoGebra has been the important part of the teaching-learning process of mathematics and it has also been used in the examinations. However, in terms of accessibility, there has been little improvement in many ILMS. This same applies to GeoGebra too. Within 2021, Norwegian Government has enforced the existing and new online system that are aimed towards the end-user, to fulfill the A and AA criteria of WCAG 2.0. As a result, the fundamental goals of this research are to study the user experience of few high school’s students and to conduct conformance testing of the GeoGebra online application against the success criteria A and AA of WCAG 2.0. For the study, two different qualitative methodologies were used. Semi-structured interview was done with the second and third year students from one of the high schools of Norway to study the user experience of using the GeoGebra. Similarly, heuristic evaluation was done by the two students from Master in Universal Design of ICT in Oslo and Akershus University College of Applied Science. The objective of the heuristic evaluation was to find out to what extent the GeoGebra has fulfilled the web accessibility criteria. The data from the semi-structured interview was analyzed based on Interpretative phenomenological analysis (IPA). After the data collection from both qualitative methods and analyzing it, this research found some interesting results.
