Exercises in a laboratory can be a daunting task for students to take on when products are produced using complex processes and hazardous materials. Working in such settings requires the students to be sufficiently prepared, since it otherwise can be dangerous for the students. Moreover, the learning environment in the laboratory can also suffer since the students will need more guidance from the teacher on simple practical matters meaning that there will be less time for focusing ON the more important learning outcomes. Supplying the students with sufficient training can be a complex and time-consuming process. This paper will describe the findings on using videos and digital learning to better prepare the students for their work in the composite laboratory at Aarhus University, where complex production processes and hazardous materials are used for producing composite specimens, which students have conceived and designed themselves.
