Geração de sequências curriculares adaptativas baseada no perfil dos alunos e materiais didáticos utilizando o algoritmo Presa-Predador

Abstract

e-Learning is the technological representation of Distance Education, being an alterna-tive that people have found to acquire academic or extracurricular knowledge. The users of these systems can access the contents anytime, anywhere simply by having a computer device with Internet access. However, for this technology to be even more used, not only as a complement, but also as a primary alternative, it is necessary to address several challenges. The focus of the main technologies based on the improvement of education, for many years, has been the transfer of information based on the central figure of a tea-cher. This aspect, together with relevant omissions, such as the contextualization of the learning experience according to the student profile, are considered the main obstacles in e-Learning adoption. One of the most interesting challenges in this field is the selection of the sequence of learning resources that considers learners characteristics at the content delivery time - Adaptive Curriculum Sequence (ACS). The ACS generation is considered a NP-Hard problem, stimulating the use of metaheuristics, particularly of Evolutionary Computing approaches. The present work proposes a solution to generate an ACS that considers the intrinsic and extrinsic information of the learner. The Prey-Predator Al-gorithm was chosen for the problem and it have been proved suitable. The proposed solution results were based on a real learning enviroment (with real learners) and show that the proposed adaptation, besides being able to select learning resources that meet the learners learning goals, positively affects the quality of understanding. Besides, the group of students who received the ACS from the proposal presents less dropout, sugges-ting a motivational factor. In addtion, the database of learning resouces was generated which may be used in future experiments, contributing to the development of this field of research.
