Short Answer Scenario 2: Imagine you read a news headline that states: “Taking notes by hand may lead to better learning.” In the study, researchers had students take notes on a TED talk in a classroom and then tested their understanding of the material with a multiple-choice exam. A third of the students were randomly assigned to take notes with a laptop, another third was randomly assigned to take notes with an iPad, and the last third was randomly assigned to take notes by hand. The results suggested that there was a statistically significant difference in exam scores such that participants who took notes by hand performed significantly better than the participants who took notes by laptop or iPad.
