Municipalities continue to seek ways to enhance communication, information and documentation for teachers, students and parents through the implementation of learning management systems in schools. In this paper, the launch of a system for K-12 schools in a municipality in Sweden is studied from the teacher perspective. Survey comments submitted by the teachers (N=470) were analysed using a modified version of Koole’s (2011) Framework for the Rational Analysis of Mobile Education. The findings show possibilities such as communication and documentation, as well as challenges related to usability, access and resistance. Lessons learned regarding the implementation of the system are presented.
