Multi-dimensional assessment on free-text answers to enhance learners´ activities and collaborations

The E-learning system is a virtual environment; hence, its supporting tools of study supervision are not strong. Although previous researchers strove for the enhancement of learning activities and collaborations but the achieved results were often sparse. In this paper we propose a method to enhance the efficiency of activities of learners. Namely, we are proposing an automatic multi-dimensional assessment (M-DA) on free text answers. In addition, we created an online environment in such a way that the learners can assess and collaborate with others. The results obtained are reassessed by the system; therefore, learners always actively study through the proposed system. The approach was applied to assess two groups of learners at the same level in an e-course. The experiment indicates that the proposed system overcome the system without M-DA.
