Question-answering through selecting and connecting peer-students

Tutors have only limited time to support the learning process. In this paper, we introduce a model that helps answering the questions of students. The model invokes the knowledge and skills of peer- students by bringing them together based on the combination of questions posed and their study progress; it supports the process with text fragments selected from the material studied. We will explain the model and the use of Latent Semantic Analysis to select and support the peers. Finally, we will discuss the results of a calibration and simulation of the model and present the first results of an experiment with over a 100 students using a prototype of the model for a period of 8 weeks
