COLLABORATIVE PROJECT-BASED LEARNING WITH CONTENT RECOMMENDATION SUPPORT

This paper aims to investigate the possible benefits of using an active learning approach, Project-Based Learning (PBL), as a way to contribute to collaborative practices in a virtual learning environment. PBL is a student-centered learning method that emphasizes activities for the development of projects and is seen as an active learning approach in which knowledge is built through the development of experimental and analytical activities. For the application of the proposed method, an educational activity was structured involving the development of a project from students' questionings in relation to a theme proposed by the teacher. Toth is a tool that was developed to support these activities, consisting in a responsive web tool for fostering collaboration between students during the development of their projects. The tool allows message exchange between participants and also the possibility of students to collaborate on projects from each other through predefined types of comments. When students are working on their projects, the tool suggests additional materials related to the subject as a way to assist students in their research processes. When teachers propose a general topic of research, they upload a "triggering text" to prompt students to the subject. This text is mined together with the students' writings, aiming at the extraction of relevant terms and keywords. The items returned from the web search (articles, books, images, videos) according to the terms coming from the mining tool are then suggested to students, making them aware of the availability of different material that may be interesting in their investigation. Preliminary results obtained with a tool that preceded Toth have shown that the ability to scan students' writings in the search for related contents has the potential to provide them with relevant recommendations. It has also been observed that the active-based learning approach has a good potential to engage students in participating in the activities proposed.
