Some difficult topics may need to be re-explained frequently. This costs a lot of time. By recording the lesson material well prepared and under controlled conditions, with or without a PowerPoint presentation or animation, a sustainable product is created in which the explanation is optimally presented. These knowledge clips can often be used for a longer period of time and can also serve as ‘work of reference’.

• subject matter that is regularly subject to change;
• transferring practical skills;
• multiple and/or longer topics. If the clip lasts longer than 5 minutes, there is a good chance that the students will lose their attention and the knowledge will not stick.
