    Automatic topology completion of TOSCA-based cloud applications
    (Informatik 2014, 2014) Hirmer, Pascal; Breitenbücher, Uwe; Binz, Tobias; Leymann, Frank
    Automation of application provisioning is one of the key aspects of Cloud Computing. Standards such as the Topology and Orchestration Specification for Cloud Applications (TOSCA) provide a means to model application topologies which can be provisioned fully automatically. Many automated provisioning engines require that these topologies are complete in the sense of specifying all application, platform, and infrastructure components. However, modeling complete models is a complex, timeconsuming, and error-prone task that typically requires a lot of technical expertise. In this paper, we present an approach that enables users to model incomplete TOSCA application topologies that are completed automatically to deployable, complete models. This enables users to focus on the business-relevant application components and simplifies the creation process tremendously by minimizing the required effort and know-how. We prove the technical feasibility of the presented approach by a prototypical implementation based on the open source modeling tool Winery. In addition, we evaluate the approach by standards-compliance and performance.

    An Intelligent Tutoring System Concept for a Gamified e-Learning Platform for Higher Computer Science Education
    (SEUH 2023, 2023) Meißner, Niklas; Speth, Sandro; Breitenbücher, Uwe
    Intelligent Tutoring Systems (ITSs) are increasingly used in modern education to automatically give students individual feedback on their performance. The advantage for students is fast individual feedback on their answers to asked questions, while lecturers benefit from considerable time savings and easy delivery of educational material. Of course, it is important that the provided feedback is as effective as direct feedback from the lecturer. However, in digital teaching, lecturers cannot assess the student’s knowledge precisely but can only provide information on which questions were answered correctly and incorrectly. Therefore, this paper presents a concept for integrating ITS elements into the gamified e-learning platform IT-REX so that the feedback quality can be improved to support students in the best possible way.

    IT-REX --- A Vision for a Gamified e-Learning Platform for the First Semesters of Computer Science Courses
    (Software Engineering im Unterricht der Hochschulen (SEUH 2022), 2022) Speth, Sandro; Becker, Steffen; Breitenbücher, Uwe; Fuchs, Philipp; Meißner, Niklas; Riesch, Anna; Wetzel, Daniel
    Digital learning is becoming increasingly important, especially in situations when students cannot attend presence lectures as we experienced during the Covid-19 pandemic. However, while there are platforms that support generic learning concepts such as multiple-choice questions, we believe that the first semesters of computer science courses can benefit from tailored learning platforms that support IT-specific learning. For example, programming tasks that are automatically checked for correctness. Moreover, in times when students cannot meet each other, self-organization and motivation quickly become severe problems. Therefore, this paper presents a vision for a gamified e-Learning platform specialized for the first semesters of computer science courses.
