Abstract. Digital Libraries (DLs) usually provide facilities for browsing and searching their collections, and can enhance noticeably learning activities. The integration of an annotation tool with a DL can foster knowledge exchange between instructors and learners. It is important that an annotation system for DLs should be easily integrated with existing DLs. This paper presents an annotation system, called DLNotes, which can be easily embedded in DLs in order to enable free-text and ontology-based annotations. DLNotes also supports supervised annotation activities and allows discussion threads to be associated with each annotation, what is particularly important for e-learning.

The use of technologies such as educational software and robotics to support the teaching and learning process is increasing. Educational robotics has proven to arouse interest in students, as it allows physical handling and active participation in the learning process. In this sense, this manuscript aims to describe the Educational Robotics research project as an Incentive to the Study of Science approved in PROPPI EDITAL No. 77/2017 - INTERNAL SOURCE 2018/2019, which had as a proposal to integrate undergraduates of Licentiate Degree in Mathematics and Computer Science of IFRS - Campus Ibirubá to jointly carry out analyzes and develop procedures for teaching and learning science (mathematics/physics) using Educational Robotics resources, motivating students of the Technical Course in Computing Integrated to High School. Thus, while this project offered an internship field for undergraduates, it promoted interest in the study of science among participants, leading them to engage and promoting greater participation.
