This paper presents the refactoring and evaluation of IDeRBlog, an educational blog platform designed to support German language acquisition in primary schools. Originally developed as part of an EU Erasmus project, IDeRBlog aims to improve students’ spelling skills through a combination of intelligent feedback and blogging features. The recent redevelopment focused on updating the user interface for mobile compatibility and integrating modern web technologies. To assess the impact of these improvements on user experience, two test classes used the IDeRBlog system during regular German lessons. Students received automated feedback on their writing, while teachers tracked progress using learning analytics to identify common error categories. The evaluation demonstrates significant improvements in usability and user experience due to the refactoring, highlighting its positive impact on both student engagement and learning outcomes.
The two mobile operating systems Android and i(Pad)OS have dominated the smartphone and tablet market for years and app providers have to offer their apps for both systems in most cases in order to be competitive or to be able to reach the majority of potential customers. In native app development, separate applications have to be written and maintained for each platform. Often, apps are developed for one platform first and the second app is developed at a later stage, after some feedback could be collected. This porting from one system to the other can be either (partially) automated or manual, but in any case, it has its challenges. Both systems were designed with different approaches and differ greatly in some parts from each other – not only visually, but also in terms of the underlying structure. To illustrate the porting process, the Android app “Schoolstart Screening App”, which was developed for the Federal Ministry of Education, Science and Research of Austria by Graz University of Technology at the OU Educational Technology, was ported so that it can be used also on iPads. Automated approaches were discussed and the chosen process is explained to get a good overview of the topic.
This work deals with the maintenance of information systems—specifically, with the maintenance of information systems that have a focus on teaching and learning. Depending on the context of an information system, there are different influencing factors for the maintenance of these systems. This work clarifies how the maintenance activities and their influencing factors differ in an information system for teaching and learning from other information systems, or why some influencing factors are particularly more important. The first step is to understand what maintenance means, why there is a need for maintenance, and which maintenance strategies can be used. Finally, the defined factors of influencing the maintenance of information systems for teaching and learning are evaluated during interviews with experts in order to be able to determine their relevance. A further part of this document is the influence of the General Data Protection Regulation (GDPR) guidelines on information systems maintenance, which came into force on May 25, 2018. These guidelines of the GDPR affect a large part of all information systems that process data—in particular, the processing of personal data. The GDPR regulates, among other things, the rights and obligations of data processing.
This paper discusses the development and testing of a gamified mathematical learning app. Said app is designed for primary school children in their first two years of learning, so that they can practice the arithmetic operations addition and subtraction in a playful way. Predefined error categories are used to specifically eliminate weaknesses. As an incentive for the learners, mascots, stars and a child-oriented look are offered, as well as a mode in which the players can compete with others worldwide and, in the case of good performance, find themselves on the leaderboard. A test run and a subsequently conducted survey with 49 school children showed that the app generally works well and that the subjective perceptions regarding the motivational ability of the mascots correlate with the overall perception of the app.
Electronic learning, with all its different variations, approaches and applications, is a very relevant topic in today’s education. E-Learning is a wide field, as it affects classes in school as well as training scenarios for adult persons. This work describes the development of two E-Learning systems: EinMalEins Trainer and Division Trainer. Both applications are part of the learning lab of Graz University of Technology. This document sums up the theoretical background of the development process as well as the realization. A lot of emphasis in this work laid on applying different testing methods, therefore thinking aloud testing as well as automated testing are handled more deeply. The methodology behind these methods is explained and the results are presented.
In the recent years, as technology grew, so did the chatbot technology. More and more companies and people are using and reaping the benefits from them. This paper shows how a chatbot for mathematical tasks, named mathbot, was developed. The chatbot uses mathematical exercises from the “Schulapps” of the LearningLab of Graz, University of Technology and combines them with textual questions to provide a useful utility for practicing. It is shown that such a chatbot could be useful for pupils and teachers by evaluating a test run in an elementary school.
