Coherence Effect

The learner needs to get a coherent, well connected representation of the main ideas to be learned. It is important to remove distracting, irrelevant material, even when the added information is artistically appealing.  Seductive details that do not address the main points to be conveyed run the risk of consuming the learner’s attention and effort at the expense of their missing the main points. 
  • Implications
    • Design the learning materials so that the main points are prominent and that removes distracting, irrelevant materials.
