An Adaptive Web-based Tutorial of Agrarian Economy

TEA was originally conceived as a Computer Aided Educational System for teaching Agrarian Economy. This system was composed by web pages of instructional contents and web pages of test questions. The biggest flaw of the system is the lack of control over the pages seen by the student. This contributed to the disorientation of students during the instruction. Also, in test questions, students only could know if they had answered correctly to it, but these questions did not give them any feedback about their global level of knowledge in the topics of the tutorial. In this paper, TEA system has been improved making it adaptive. This has been achieved by using two tools: SIGUE and SIETTE. SIGUE is a web-based tool that converts non-adaptive courses into adaptive, and SIETTE is a web-based evaluation tool using adaptive tests. The functionalities of both tools have been integrated into a homogeneous adaptive TEA.
