The success of project-based learning courses relies on how freely and openly students can discuss their task-oriented problems in small teams. The most effort-intensive part of the online teaching of project-based learning is to enhance collaboration among students. This paper highlights the challenges we faced, how we overcame some of these challenges, and our lessons learned. Additionally, the results from a student survey conducted during the semester show the students’ feedback on online teaching.enhttp://rightsstatements.org/vocab/InC/1.0/Allgemeines, WissenschaftErziehung, Schul- und BildungswesenConference Paper10.15480/882.2863http://gaia.cs.umass.edu/sigcomm_education_workshop_2020/papers/sigcommedu20-final22.pdf10.15480/882.2863Conference Paper
