In class and online using a course management system in the framework of the subject matter of Didactics of Informatics. This work presents an empirical study aiming to compare the implementation of the case activities Although many of the studies found in bibliographyĬompare the effectiveness of in class versus online teaching, these studies do not focus on the comparison of specific teaching Technologies in education has transformed the way teaching is being conducted. In recent years, the ongoing use of e-learning The use of cases in education in the framework of activities is very effective, as students’ engagement in the solution ofĪuthentic, and thus interesting, problems provides them motivation for learning.
The study concludes with suggestions for future research and implications for system developers who are interested in CBR retrieval systems. This study did not find a significant correlation among search time, search correctness and search satisfaction. However, the best match mental models do not guarantee less search time in finding the results. This study also that subjects with the best match mental models have significantly higher search correctness and search result satisfaction than subjects without the best match mental models. Qualitative analysis for the subjects’ post mental models revealed that subjects in the conceptual description group seem to have more complete mental models of the best match system than those in the search practice group. However, the search practice group spent significantly less time than the conceptual description group in finding the results. The results of this study revealed that the conceptual description and search practice treatments do not have significantly different effects on the types of user’s mental models, search correctness, and search satisfaction. This study also found examined how the presence of a mental model affects the users’ search performance and satisfaction in this system. This paper reportes a study that investigated the effects of conceptual description and search practice on users’ mental models and information seeking in a case-based reasoning retrieval (CBR) system with a best match search mechanism.
