- Text allows abstraction.
- Text has the lowest density.
- Text has the lowest development cost.
In any case, we must take into account the fact that the text is read on a screen (see Module 3, DEVELOPMENT).
We recommend (cfr. Mayer) to combine text as much as possible with other forms (image, drawing, diagram, video, …). Text can e.g. also focus on something that the student would overlook in a video.
