    SQLValidator – An Online Student Playground to Learn SQL
    (Datenbank-Spektrum: Vol. 21, No. 2, 2021) Obionwu, Victor; Broneske, David; Hawlitschek, Anja; Köppen, Veit; Saake, Gunter
    The Structured Query Language (SQL) is the most widely-used language in database-related courses. As a consequence, writing SQL queries is a fundamental expectation from any university course in database systems. Practical exercises are an essential part of the SQL learning experience. These exercises enable participants to practice and acquire experience in the use of the different SQL concepts, such as clauses, predicates, and expressions. To this end, we developed the tool SQLValidator as a web-based interactive tool for learning and practicing SQL. Apart from using it for teaching, we also use it to administer questionnaires and practice tests to improve students’ learning experience. In this paper, we present the architecture and functions of SQLValidator. In order to assess the usefulness of SQLValidator, we monitor the performance of our students based on the semester activities and examinations. Our evaluation shows that SQLValidator is an effective tool that improves a student’s learning experience when learning SQL.

    Towards a Game-Based Programming Learning Environment for Kids
    (Mensch & Computer 2011: überMEDIEN|ÜBERmorgen, 2011) Schmidt, Ralf; Masuch, Maic; Othlinghaus, Julia
    In this paper we describe our vision of an engaging, game-based programming learning environment for novice learners aged 10 to 13. We aim to support class teaching situations until pupils reach an advanced level of knowledge, allowing for a smooth transition to general purpose languages. As a first hands-on approach, the prototype “Plumps” is presented, which features scenarios with goal-based didactics as well as selected aspects of a comprehensive game-based motivational concept. We further discuss the positive and constructive feedback of an informal evaluation carried out among 21 secondary school children to assess the general acceptance. Finally, we conclude with a reflection and discuss next steps towards a further multidisciplinary research and development.

    Virtual Reality als Trainingsmethode: Eine Laborstudie aus dem Industriebereich
    (HMD Praxis der Wirtschaftsinformatik: Vol. 59, No. 1, 2022) Wolfartsberger, Josef; Riedl, René; Jodlbauer, Herbert; Haslinger, Niklas; Hlibchuk, Andrii; Kirisits, Alexander; Schuh, Stefan
    Virtual Reality (VR) gilt als vielversprechende Technologie, nicht zuletzt deshalb, weil damit komplexe Inhalte vermittelt werden können. Da VR ein hohes Potenzial für Interaktivität und Immersion aufweist, findet die Technologie auch in der Industrie Anwendung, beispielsweise für die realitätsnahe Simulation von Montage- und Instandhaltungsarbeiten. Wissenschaftliche Befunde zur Wirksamkeit des Lernens in industriellen VR-Umgebungen existieren bislang kaum. Es ist daher auch unklar, wie Lerneffekte in virtuellen Umgebungen verbessert werden können. Der vorliegende Artikel untersucht, ob VR-gestütztes Training im Vergleich zu klassischem training-on-the-job (begleitet von einem Tutor) zu einer Steigerung des Lernerfolgs führt. Basierend auf einem VR-Trainingstool zum Erlernen von Montageabläufen wurde eine Laborstudie mit 24 ProbandInnen durchgeführt. Die Ergebnisse zeigen, dass VR-gestütztes Training zwar als weniger anstrengend empfunden wurde, der Lernerfolg jedoch im traditionellen training-on-the-job signifikant besser ausfiel. Auf Basis dieser Erkenntnisse werden die Chancen und Risiken aktueller VR-Trainingssimulationen diskutiert und konkrete Handlungsempfehlungen zur Steigerung des Lerneffekts formuliert. Virtual reality (VR) is considered a promising technology because it can be used to convey complex contents. Since VR has a high potential for interactivity and immersion, the technology is also used in industry, for example for the realistic simulation of assembly and maintenance work. However, in this context there are hardly any scientific findings on the effectiveness of learning in VR environments. It is also unclear how learning can be improved in virtual environments. This article investigates if VR-supported training leads to an increase in learning success compared to classic training-on-the-job (accompanied by a tutor). Based on a VR training tool for learning assembly processes, a laboratory study was conducted with 24 participants. The results show that although VR-supported training was perceived as less strenuous, the learning success (measured with assembly time and error rate) was significantly better in traditional training-on-the-job. Based on these findings, the opportunities and risks of current VR training simulations are discussed and recommendations for action to increase the learning effect are formulated.
