As part of my work with the MIT Integrated Learning Initiative (MITili), I had the good fortune to be part of an MIT team that conducted “science of learning” research at the Masie Learning 2017 conference in Orlando.
With the help of 150 Masie Learning 2017 conference participants, an MIT research team set out to address the hot topic of micro-learning. The participants interacted with one of three variations of an elearning video on one of the conference themes, cybersecurity. The MIT team used EEG headbands to measure attention during the learning experience and a post-test and survey the next day to capture knowledge gained.
. . .
Taking a cue from one of the conference themes, cybersecurity, the MIT team created three elearning video variations: “Original” (the original 8-minute video), “Interrupted” (the same content as Original, but interrupted three times with short unrelated work tasks), and “1.5x” (the same content as Original, but increased to 1.5x the speed of the Original video.
. . .
The mean scores of the Original and Interrupted cases are essentially identical, with the 1.5x case trailing by a bit. However, the differences are not statistically significant–that is, none of the three variants can be said to have outperformed the others (the error bars represent the standard error of the mean).
. . .
The mean scores of the late morning case are the highest, with the early morning scores the lowest. The two afternoon means fall in the middle. The difference between the late morning and early morning scores are statistically significant, but the differences between late morning and both afternoon scores and between both afternoon scores and early morning are not (the error bars represent the standard error of the mean).

As part of our conference research effort, my colleague Kana and I had the great fortune to briefly meet former First Lady Michelle Obama. In her keynote talk and in her brief conversation with us, she was the epitome of strength, grace, and thoughtfulness.
