Interactive multimedia educational content has recently been of interest to attract attention on the learner and increase understanding by the latter. In parallel several open source authoring tools offer a quick and easy production of this type of content. As such, our contribution is to mediatize a course i.e. 'English' with the authoring system 'Xerte' which is intended both for simple users and developers in ActionScript. An experiment of course is conducted on a sample of a private school's students. At the end of this experience, we administered a questionnaire to evaluate the device, the results obtained, evidenced by the favorable reception of interactive multimedia integration in educational content.

Nowadays, the video documents like educational courses available on the web increases significantly. However, the information retrieval systems today can not return to the users (students or teachers) of parts of those videos that meet their exact needs expressed by a query consisting of semantic information. In this paper, we present a model of pedagogical knowledge of current videos. This knowledge is used throughout the process of indexing and semantic search segments instructional videos. Our experimental results show that the proposed approach is promising.
