Contribution: Results and conclusions on the use of transactive memory system (TMS) in software engineering (SE) education in student project teams that consist of undergraduate and postgraduate students are documented. This can be valuable for the adoption of this learning approach and team formation by other universities and institutes. Background: Preparing students for the SE industry requires bringing them in close collaboration to real-world tasks. This is usually performed via students carrying out software projects, working in teams. In such environments, the knowledge sharing and the interactions within the team are worth investigating, as they can affect the outcome of the student collaboration and can provide insight on how the collaboration is valued by the team members. Research Questions: 1) What is the effect of TMS on students in SE education? 2) Do parameters, such as gender, affect TMS development? 3) Does the inclusion of a project manager with more expertise affect TMS? Methodology: Students were divided into teams working on SE projects. Teams consist of both undergraduate and postgraduate students. Data from students on TMS for consecutive academic years were gathered. Findings: TMS is present in student teams and some of its scale items are affected by parameters, such as the team composition and the project type. TMS also affects performance.
