Estudo da relaÃÃo entre domÃnio tecnolÃgico, interaÃÃo e aprendizagem "colaborativa" na EaD on-line pelo uso de um modelo de equaÃÃes estruturais. / Study of the relationship among technological domain, interaction and collaborative learning in the e-learning through the application of a model of structural equations.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Embora a educaÃÃo a distÃncia (EaD) nÃo seja uma modalidade educativa recente, seu novo formato, modernizado com a inserÃÃo das TIC, sobretudo do computador e da Internet, lhe aduz recursos de interaÃÃo que modificam totalmente suas funcionalidades e resultados potenciais. Motivada por essas novas funcionalidades e potencialidades disponÃveis na EaD pelo emprego do computador e da Internet, esta tese teve como objetivo testar um modelo hipotÃtico supondo a relaÃÃo entre as variÃveis endÃgenas domÃnio tecnolÃgico, interaÃÃo e aprendizagem âcolaborativaâ em curso de EaD on-line. Para concretizaÃÃo desse objetivo, como iniciativa pioneira nessa Ãrea de pesquisa, aplicou-se a modelagem com equaÃÃes estruturais, mediante a qual foi confirmada a existÃncia de uma trÃplice relaÃÃo entre o domÃnio tecnolÃgico dos alunos, as interaÃÃes tutor-aluno e aluno-aluno e a aprendizagem âcolaborativaâ. O modelo geral apresentou qualidade de ajuste aceitÃvel, assim como as equaÃÃes estruturais mostraram boa confiabilidade de construto e R2 com bons poderes de explicaÃÃo da variabilidade das variÃveis latentes. Ademais, a investigaÃÃo constatou, tambÃm, que a freqÃÃncia de uso da Internet e das ferramentas e-mail e fÃruns para discussÃo, bem como de ferramentas de comunicaÃÃo (tais como MSN, Yahoo Messenger, entre outras) influenciam diretamente o domÃnio tecnolÃgico do aluno de EaD, sendo o domÃnio tecnolÃgico realmente necessÃrio para um bom desempenho em um curso de EaD on-line. A investigaÃÃo constatou, ainda, que as interaÃÃes tutor-aluno e aluno-aluno, mediadas pelas ferramentas de comunicaÃÃo e atividades âcolaborativasâ, se fazem de forma significativa na EaD on-line, e contribuem efetivamente para aprendizagem dos alunos nesta modalidade de ensino. Conclui-se, entÃo, que alunos possuidores de uma capacitaÃÃo tecnolÃgica adequada terÃo condiÃÃes de realizar interaÃÃes mais fortes, o que, conseqÃentemente, influenciarà positivamente sua aprendizagem em um curso de EaD on-line. / Although distance learning is not a recent educational model, its new format, which has been modernized with the insertion of information and communication technologies, especially the computer and the Internet, has brought resources that enable interaction at a higher level, totally modifying its function and potential results. Motivated by these new functionalities and potentialities, which the use of computer and Internet has brought, this Doctoral Dissertation has as its objective to test a hypothesized model involving the relation between technological expertise, interaction and collaborative learning from an online distance learning course. In order to achieve this objective, as a pioneer initiative in that research area, the analyses were carried out through the application of structural equations modeling which confirmed the existence of a triple relation between student technical practice, teacher-student and student-student interactions and collaborative learning process. The general model showed acceptable goodness of fit as well as the structural equations showed significant coefficients, the construct reliabilities were quite high and R2 exhibits good explanation power of the endogenous variables. It has been observed also the frequent use of the internet and communication tools (such MSN, Yahoo Messenger, among others) made available through e-mails and chat-rooms â for discussion, along with other communication tools, such as, those which have directly influenced the technological advances of online distance learning students, making this technological expertise absolutely necessary for a good development of an online distance learning course. It has been noticed the interactions between teacher-student and student-student through the communication tools and collaborative activities characterize the interactions that occur in online distance learning, and contribute effectively in the learning process of students in this type of learning environment. At the end it is emphasized that the students who have mastered an adequate technological capacity will have the ability to acquire a more strong interaction which will consequently influence and bring positive impact to their learning in an online course.
