- Perusall’s machine learning towards self-regulated learningPublication . Francisco, Manuela; Amado, CristinaThis current work presents exploratory research related to Perusall activity. One of the objectives of this study was to analyze the Perusalll’s features, with emphasis on peer work, which can increase individual motivation facilitating self-regulation learning. Perusall is a social web tool that uses a machine learning algorithm, which assesses the quality of annotations and students’ engagement. This tool was integrated with the LMS of Universidade Aberta (Portugal) and it was used as a pilot project in a Curricular Unit, from the 2nd year of the Education undergraduate program. We designed a collaborative activity inspired by Inquiry-based Learning and peer-instruction, to be performed on Perusall. 115 students, from 2 classes, were involved. To assess students’ work, their engagement and motivation (basis for self-regulation) we analyzed Perusall ́s reports and scoring based on 6 different components. We also asked students to report positive and negative aspects related to their experience with Perusall. Our findings confirm that collaborative reading tools can help students to get more involved in self-learning, as well machine learning can help instructors work, namely monitoring and assessment tasks.
- Reflection on human and automatic image description in elearning contextPublication . Francisco, Manuela; Amado, CristinaIn the current year, Perusall was integrated with the LMS of Universidade Aberta (Portugal) and will be used as a pilot project this semester, in the Accessibility in Education and Training Curricular Unit (CU), from the 2nd year of the Education undergraduate programme. The course is entirely distance learning and the interaction is fundamentally asynchronous. The CU was designed according to the university's pedagogical model and provides 2 assessment moments throughout the semester with a weight of 20% each, and a final assessment moment with a weight of 60%. Two classes are involved with 68 students each. The activity designed at Perusall will take place between April 10 and May 12, 2021, being assessed with a weight of 20% of the final grade. In this activity, in Perusall, it is intended that students read an available document about the techniques to create accessible digital content, they shall elaborate questions about it and vote on the 3 questions that they consider to have aroused the most interest on the topic.Seeking to create more meaningful learning situations, a pedagogical approach inspired by the Inquiry-Based Learning model (IBL) was adopted. Some authors refer that the IBL allows students a greater reflection and involvement with the theme under study and its applicability in real contexts. It is also mentioned in the literature that this model combined with a socio-constructivist approach enhances a greater awareness of the problems and solutions related to the theme, still allowing to innovate in new scenarios. Thus, based on these assumptions, a collaborative activity was designed, in which a document is provided for reading, reflecting and questioning. Each student must ask 3 questions that relate the theory to the practice, being able to present concrete scenarios. It is also intended that each student votes on the 3 questions that upraised his attention to the topic, that relates theory with practice and/or that motivates more research on the subject. The evaluation focuses on the quality of the questions created and voted on, as well as on the score generated by Perusall where a holistic evaluation was configured based on access, interactions with the document and the other students. The goal is to provide students an overview of the main topics that aroused more interest and questioning within the theme worked in this module.
