Especially in large university courses, an automated assessment of models can improve the quality of teaching and learning. While there are many different approaches to automatically assess conceptual models, these approaches, however, often only tackle a single aspect or a single type of conceptual model. In this paper, we aim to take a comprehensive perspective on the topic and shed light on the current state of the art and technique. Furthermore, as assessment approaches have to be developed in accordance with appropriate teaching or learning activities and desired learning outcomes, we inquire in which settings automated assessment approaches are included and to which extent didactic aspects are taken into account. To this end, we have conducted a systematic literature review in which we identified 110 relevant publications on the topic which we have analyzed in a structured way. The results provide answers to five relevant research questions and pinpoint open issues which should be inquired in further research. 2023-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/41541 Tool-based Codification in Business Process Improvement and the Impact on Problem-Solving Johannsen, Florian; Mang, Fabian; Hans-Georg, Fill; Hofmann, Sara Business process improvement (BPI) is an important task in times of quickly changing customer requirements and evolving technologies. A variety of BPI approaches were developed in recent years, however, the proper codification of results created in BPI projects has not been properly investigated yet. In this respect, the paper at hand examines the impact of tool-based codification approaches on problem-solving in BPI. Moreover, the effect of the design either as a spreadsheet-based or a conceptual model-based tool on user satisfaction is analyzed. For that purpose, we revert to two tools we developed, which both offer the identical functionality but diverge in the techniques of codifying results: spreadsheet templates on the one side and conceptual models on the other side. In our study, the form of codification tremendously affected the perceived user satisfaction whereas the results received for problem-solving did not show a clear preference. Regarding the former issue, the beneficial role of conceptual models for codifying results with the help of software tools could be demonstrated. 2023-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/41540 Multi-Level Modeling with Openflexo/FML Sylvain Guérin, Joel Champeau Model federation is a multi-model management approach based on the use of virtual models and loosely coupled links. The models in a federation remain autonomous and represented in their original technological spaces whereas virtual models and links (which are not level bounded) serve as control components used to present different views to the users and maintain synchronization. In this paper we tackle the EMISAJ multi-level process modeling challenge, which consists in providing a solution to the problem of specifying and enacting processes. Solutions must fulfill a number of requirements for a process representation defined at an abstract process-definition level and at various more concrete domain-specific levels, resulting in a multi-level hierarchy of related models. We present a solution based on model federation and discuss the advantages and limitations of using this approach for multi-level modeling. Concretely, we use virtual models and more precisely the Federation Modeling Language (FML) that serves to describe them as the main building block in order to solve the process modeling challenge whereas the federation feature is used as a means to provide editing tools for the resulting process language. Our solution fulfills all the challenge requirements and is fully implemented with the Openflexo framework. 2022-01-01T00:00:00Z
