Present an appropriate amount of media. Media is an important element, which should be used to facilitate learning, but too much media can have the reverse effect:
If a case presents too little media, the student may lose clarity and the learning effect will be lost.
If a case presents too much media, it may overload the case and distract the student.
Use media according to the defined learning objectives. For example: If you want the student to be able to detect a heart attack on an ECG, it is advisable to insert an ECG.
A good learning effect can be achieved by embedding media into a question.
It is also helpful to provide a text alternative when presenting video or audio. This enables the content to be conveyed even if the media cannot be viewed or heard (e.g., because of technical problems).
