Is Passive learning actually Passive? - apparently not

Passive Learning Imprints On The Brain Just Like Active Learning

ScienceDaily (July 15, 2008) — It's conventional wisdom that practice makes perfect. But if practicing only consists of watching, rather than doing, does that advance proficiency? Yes, according to a study by Dartmouth researchers. They determined that people can acquire motor skills through the "seeing" as well as the "doing" form of learning.

This study, to my mind, may possibly have implications for language learning as well - a student needs to produce language - but how much is learned simply by listening? Does the brain model sentences that are heard in a similar way to sentences that are spoken? This is of particular interest to me, as the methodology of the Latinum podcast is largely passive, yet, according to user feedback, is highly successful at instilling the patterns of the language. If the brain indeed responds to passive experience - visual, or auditory (this study does not deal with auditory), then this makes sense. There is then, no such thing as 'passive learning'. The brain is equally active in both scenarios.

The upshot - it is worthwhile reading to your students, and repeating short dialogues with them, and getting them to listen to Latin, as well as read and write it.

"It's been established in previous research that there are correlations in behavioral performance between active and passive learning, but in this study we were surprised by the remarkable similarity in brain activation when our research participants observed dance sequences that were actively or passively experienced," says Emily Cross, the principal investigator and PhD student at Dartmouth. Cross, who earned her degree in June, is currently a post-doctoral fellow at the Max Planck Institute for Cognitive and Brain Sciences in Leipzig, Germany.

Cross and her collaborators used a video game where players have to move in a particular sequence to match the position of arrows on the screen, similar to the popular Dance Dance Revolution game. The researchers measured the skill level of participants for sequences that were actively rehearsed daily, and a different set of sequences that were passively observed for an equivalent amount of time. Brain activity when watching both kinds of sequences (as well as a third set of sequences that were entirely unfamiliar) was captured using fMRI, functional magnetic resonance imaging. The study focused on the Action Observance Network (AON) in the brain, a group of neural regions found mostly in the inferior parietal and premotor cortices of the brain (near the top of the head) responsible for motor skills and some memory functions.

"We collected fMRI data before and after five days of both visual and physical training," says Cross, "and there was common AON activity when watching the practiced and observed dance sequences."

This research contributes to a growing body of study about how people learn and how best to help people with brain injuries. Cross explains that future studies might consider how such overlap between physical and observational learning at the brain level can improve upon rehabilitation therapies for individuals affected by physical or neurological injury.

Cross's co-authors on the paper were David J. M. Kraemer, Antonia F. de C. Hamilton, William M. Kelley, and Scott T. Grafton, all currently or formerly associated with Dartmouth's Department of Psychological and Brain Sciences. Kraemer is currently a postdoctoral fellow at the University of Pennsylvania, Hamilton is now on the faculty of the University of Nottingham's School of Psychology, Kelley is associate professor of psychological and brain sciences at Dartmouth, and Grafton is a professor of psychology at the University of California, Santa Barbara.

I was in a course recently and a man was telling me about some research that showed that even when reading silently, parts of the brain involved in speech-production were active, as if they were subvocalising, even if their reading was entirely silent. Similar kind of thing.
