In Sweden, technology-mediated participation has increased in tertiary education, which has led to changing conditions for its delivery. However, one part has proven more resistant to change, technology-mediated or not: the supervision of students' undergraduate dissertation work. This article presents a study that analyses technological applications to mediate supervision of students' undergraduate dissertation work. It is shown that students in general find such mediated participation helpful for supervision, both one-to-one and collaboratively. Mediation by technologies and collaborative forms for the supervision of students' undergraduate dissertation are, therefore, suggested as productive ways to enhance students' learning.
