This dissertation studies different didactic approaches for learning software design to improve the way we teach students software design. The research in the dissertation questions whether we can assess software design skills, what guidance is needed for the improvement of students’ understanding of software design and how to motivate and engage students for learning software design. The research explores the following: an instrument for measuring software design skills based on design principles, the gamification of learning software design, revealing students’ software design strategies, the use of peer-reflection for uncovering the difficulties students have during software design tasks, the use of teaching assistants as bridge between the lecturer and the students, the automation of grading software designs with machine learning, guiding feedback by a pedagogical agent and a workshop for engaging students into the process of software development. The research contributes to the future education of software design. Show less

Show moreWe address two problems in Software Engineering. The first problem is how to assess the severity of software defects? The second problem we address is that of studying software designs. Automated support for assessing the severity of software defects helps human developers to perform this task more efficiently and more accurately. We present (MAPDESO) for assessing the severity of software defects based on IEEE Standard Classification for Software Anomalies. The novelty of the approach lies in its use of uses ontologies and ontology-based reasoning which links defects to system level quality properties. One of the main reasons that makes studying of software designs challenging is the lack of their availability. We decided to collect software designs represented by UML models stored in image formats and use image processing techniques to convert them to models. We present the 'UML Repository' which contains UML diagrams (in image and XMI format) and design metrics. We conducted a series of empirical studies using the UML Repository. These empirical studies are a drop in the ocean empirical studies that can be conducted using the repository. Yet these studies show the versatility of useful studies that can be based on this novel repository of UML designs. Show less
