This paper reports on experience from teaching basic software engineering concepts by using Extreme Programming in a second year undergraduate course taken by 107 students. We describe how this course fits into a wider programme on software engineering and technology and report our experience from running and improving the course. Particularly important aspects of our setup includes team coaching (by older students) and "teamin-one-room". Our experience so far is very positive and we see that students get a good basic understanding of the important concepts in software engineering, rooted in their own practical experience.
