70% Learning from challenging assignments, 20% from others and 10% from coursework (formal), that’s a golden rule of learning theory. But where does it come from? Is it proven? Bob Eichinger explains.
To Whom It Apparently Concerns,
Yes Virginia, there is research behind 70-20-10!
I am Robert W. Eichinger, PhD. I’m one of the creators, along with the research staff of the Center for Creative Leadership, of the 70-20-10 meme [the dictionary defines a meme as an “idea, behavior, or style that spreads from person to person”].
At the time in the late 1980s, Michael Lombardo and I were teaching a course at the Center called Tools for Developing Effective Executives. […] One of the study’s objectives was to find out where today’s leaders learned the skills and competencies they were good at when they got into leadership positions.The study interviewed 191 currently successful executives from multiple organizations.

Overall, across the three scoring measures in the study, fine-grained performed 22.2% better than the blocked group and 8.4% better than the medium-grained group. The fine-grained group, with their “micro” content and frequent assessment questions, fared better than both competing groups in every category. From this study, it would appear that bite-sized content is, indeed, better.
The researchers mentioned two dynamics potentially in effect. First, the larger amount of material and questions given to the blocked group might have “put greater demands on learners,” resulting in them having to do more work to “access necessary information from their memory.” In other words, stockpiling information slowed down the process of retrieving it. Sounds familiar.
Second, the blocked group could have suffered from having less feedback than the medium and fine groups: “Longer study phases without learning questions may lead to uncertainty about whether they have understood all relevant content or not.”
