Recently, learning management systems have been introduced in the Norwegian school system, including vocational schools. Some vocational teachers have been sceptical about using learning management systems in vocational education and training. This study examined if the vocational teachers' use of a learning management system facilitated the students' opportunities to prepare for the tasks that will be part of their future as an apprentice. The research question was How does the introduction of learning management systems in vocational education and training affect learning? In vocational education and training, the transfer of tacit knowledge from master to apprentice has traditionally played an important role in the teaching. This transference of knowledge takes place in a face-to-face setting and in an interaction between master and apprentice which is based on acting, showing, explaining, and commenting. Documentation requirements through learning management systems appear to strengthen the vocational students' understanding of work tasks they will encounter as apprentices in the workplace. Learning management systems allows for the transference of tacit knowledge, and the documentation also appear to strengthen the communication between students and teacher.
