On January 27, 2021 students at the Department of Information and Communication Engineering presented projects they implemented using the ALIEN problem-based learning platform. This work was the result of group projects. Students were divided into 17 teams of 3 – 5 individuals, for a total of 80. Each team was assigned a topic to be solved through problem-based learning, on which they worked for a period of 3 weeks. Each team submitted their work and report to the instructor. In addition, each team presented their work to instructor and other teams, with the instructor providing feedback. Most teams worked on different topics. Some worked on the same topic, but introduced different solutions.
