Impact of a remote lab on teaching practices and student learning

Remote Laboratories have become part of current teaching and learning, particularly in engineering. Their potential to aid students beyond their hands-on lab classes has been a matter of discussion in literature. Teachers and researchers are aware that the thorough analysis of both strengths and shortcomings of remote labs in didactical implementations may not only lead to the improvement of these resources but also of the pedagogical implications in engineering classes. The present study was carried out in a Higher Education Institution in Brazil in two different courses during three consecutive semesters where a remote lab (VISIR) addressing electric and electronic topics was implemented, yielding 471 students' academic results and opinions. These students' results (while using VISIR) cross-analysed with the course characteristics, reveal some factors teachers may tackle to foster student learning and motivation. The conclusions point to the need for VISIR interface modernization and showed it is more useful in basic courses than in more advanced ones, when dealing with classic lab experiments. Results also show that teachers' involvement plus their ability to brief students on VISIR's usefulness have a significant influence not only on students' performance but also on their perception of learning and satisfaction with the tool. In the analysed cases, the students with more learning needs seemed to be the ones who could benefit more from VISIR.
