Re-engineering of Pedagogical Scenarios Using the Data Combination Language and Usage Tracking Language

The tracks analysis concerning students' actions logged by Technology Enhanced Learning systems can help teacher to improve their pedagogical scenarios making them relevant to students. Besides, sharing and reusing teachers' know-how and experience in the session analysis of learning systems also facilitate their scenario enhancement. In this paper, we present our proposal for obtaining these goals. We first describe the calculation method of pedagogical indicators from the tracks collected using the Usage Tracking Language and Data Combination Language. Then, we present our developed tool which allows executing these indicators. We also present results which validate our proposal with the tracks from the real learning environment. Our approach can be used to support engineering and re-engineering of pedagogical scenarios in Technology Enhanced Learning systems.
