Prior studies in the Computer Science education literature have illustrated that novices make many mistakes in composing SQL queries. Query formulation proves to be difficult for students. Only recently, some headway was made towards understanding why SQL leads to so many mistakes, by uncovering student misconceptions. In this article, we shed new…

Within the last decades, a new way of policymaking has become increasingly prominent: civic hackathons. However, in education policy research, hackathons have not been broadly addressed so far. With this article, we contribute to closing this research gap by empirically investigating the educational #wirfürschule (#wfs) Hackathons that took place…

Agent-based modeling is a promising tool for familiarizing students with complex systems as well as programming skills. Human-environment systems, for instance, entail complex interdependencies that need to be considered when modeling these systems. This complexity is often neglected in teaching modeling approaches. For a heterogeneous group of…

Data science surrounds us in contexts as diverse as climate change, air pollution, route-finding, genomics, market manipulation, and movie recommendations. To open the "data-science-black-box" for lower secondary school students, we developed a data science teaching unit focusing on the analysis of environmental data, which we embedded…

This research investigated how the bug tracker database of the Virtual Learning Environment (VLE) Moodle is developed as an application of crowd work. The bug tracker is used by software developers, who write and maintain Moodle's code, but also by a wider public world of ordinary Moodle users who can report bugs. Despite many studies of the…

Argumentative scripts for computer-supported collaborative learning are scaffolds that prompt learners to take over distributed roles and to move through a sequence of activities that specify an argumentative learning discourse. Argumentative scripts may lead to suboptimal effects on learning outcomes when their level of scaffolding does not fit…

As we talked with school teachers about the use of physical computing systems in class, one major drawback of these systems became obvious: almost nobody--next to enthusiastic autodidacts--has been able to tell us on an abstract basis for which educational purposes a certain physical computing system can be used, i.e. in a goal-oriented way. This…

Previous research on gender differences in young people's digital development has shown that boys and girls differ in frequency and type of internet use, but vital gaps in the literature remain. In recent years, gender is increasingly considered to be a multidimensional concept with a growing number of young people identifying as non-binary (i.e.…

Intelligent tutoring systems can support students in solving multi-step tasks by providing hints regarding what to do next. However, engineering such next-step hints manually or via an expert model becomes infeasible if the space of possible states is too large. Therefore, several approaches have emerged to infer next-step hints automatically,…

The success of an application programming interface (API) crucially depends on how well its documentation meets the information needs of software developers. Previous research suggests that these information needs have not been sufficiently understood. This article presents the results of a series of semistructured interviews and a follow-up…

Scientific issues like the behavior of wild and domesticated animals can serve as a motivation to learn programming concepts. Instead of following a systematic introduction, the students directly dive into programming and start immediately with their projects. In this constructionist approach the educational challenge for the teacher is to provide…

We report on the development, validation, and implementation of a collection of test items designed to detect misconceptions related to first-year computer science courses. To this end, we reworked the development scheme proposed by Almstrum et al. ("SIGCSE Bulletin" 38(4):132-145, 2006) to include students' artifacts and to…

Assessment is an essential element in learning processes. It is therefore not unsurprising that almost all learning management systems (LMSs) offer support for assessment, e.g., for the creation, execution, and evaluation of multiple choice tests. We have designed and implemented generic support for assessment that is based on assignments that…

The genre of educational adventure games is a common and successful choice in game-based learning. The games combine captivating narratives that motivate players to continue playing with game mechanics that are conductive to learning: the gameplay is slow-paced, allowing players to learn at their own pace, and focused on puzzles that can be…

University education often suffers from a lack of an explicit and adaptable didactic design. Students complain about the insufficient adaptability to the learners' needs. Learning content and services need to reach their audience according to their different prerequisites, needs, and different learning styles and conditions. A way to overcome such…
