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.
