This paper presents the results of an experimental project in which media students created a short video. The students in groups of 4 or 5 used concept maps for collected their ideas about organizing the project. The analysis of the concept maps revealed that two groups were product-oriented, one group was workflow-oriented, and two groups used concepts that belonged to both categories. The contents of the concept maps also reflected students' prior knowledge and skills related to the task. In a joint discussion of the concept maps, students created a to-do list for shooting the video, which was an important activity to build common knowledge. This project confirms that the use of concept maps is a useful tool for developing students' professional skills.
