This paper discusses students perceptions from one international exchange; the Nordic network ALKA. The network organizes an intensive course week every year. The purpose was to make a pilot study about how students use the subject content and network connections established during the ALKA intensive course week in their teaching. A questionnaire was sent out to 22 former teacher students that have participated in the course during 2010-2013. All informants are very satisfied with the course content, the experiences from the intensive course and the contacts established during the course. However, none of the participants express that the intensive course have generated in co-operation with some of the colleagues from other countries. Instead, all of the participants in the study have used the course content in their teaching or teacher training. The meeting with new landscape, animals and plants has been used in geography or biology lessons. Also the didactical discussions during the course have inspired some of the students in their teaching. Particularly the out-door education situations have inspired the teacher students to move their science lessons outside the classroom
