Once in a while, you encounter an idea that explains some things you have found puzzling. This is the case with the concept of “Desirable Difficulty“. This concept would be one way to understand my previous post on the advantages of taking notes by hand over taking notes on a laptop. Taking notes by hand is more demanding for most and learners compensate by summarizing content before recording. There are long term benefits to generating summary content over recording more verbatim information.
Bjork explains how a tendency to be misled into engaging in activities that seem to offer an immediate advantage may have less productive long term consequences. He differentiated retrieval strength and storage strength. Learning that is too easy (e.g., cramming) can result in an immediate advantage in retrieval strength, but may limit the development of storage strength. Long-term benefits depends on the development of storage strength.
This distinction can be applied to the immediate advantage of taking more complete verbatim notes over notes that require personal understanding (i.e., a summary).
As I hope is apparent, personal decisions are at the core of the problem. You tell students to space their study and not cram or work with their notes to create interpretations and not just verbatim copies of what was presented, but what easiest and falsely perceived to be more useful often win out.
One more comment – the suggestion of purposefully making things a bit more difficult must be carefully interpreted. The point is about engaging in cognitive processes that are more productive and perhaps more demanding and not to create needless struggles.
