Throwback Thursday: Motivating Students

This post was originally published in July of 2013

There are some things children are motivated about on their own and some things we need to help them find motivation for. So, what are the best ways to motivate using brain research?

First you need to know about the nucleus accumbens. For those that want this simplified, it's known as the reward center of the brain. It's a limbic structure that sends dopamine throughout the brain. This is the specific part of the anatomy that generates and sustains motivation. When you think dopamine you probably think Ritalin and ADHD, so let's start our discussion there.

Volkow (2009) found a disruption in two dopamine reward/motivation pathways among adults with ADHD. The severity of this disruption was related to the severity of inattention. Another study done in Barcelona, found that children with ADHD have a smaller ventral striatum (including the nucleus acumbens), especially on the right side. The volume was correlated with hyperactivity. We know that Ritalin produces significant levels of dopamine in the brain. This increases motivation and makes tasks seem more interesting. When you look at brain wave activity in typical kids versus ADHD kids there is a huge difference. The theta/beta ratio for typical kids is 4:1, while the ratio for ADHD kids is 9:1. For some kids necessary tasks require a Herculean effort. 

Typically, our society adds pressure and stress when people are not completing required tasks. It has been proven that when under stress, students work harder, but produce poorer quality work. The more stress you apply, the worse the results. While students are trying and giving it their all, they accomplish less. This also decreases motivation and makes students want to avoid challenges. This becomes even more harmful in the long run.

Sleep also plays a huge part on working memory, attention, and reaction time. Forth and sixth graders were paid to sleep one hour more or less for three consecutive nights. After a loss of 35 minutes each night for 3 nights (most couldn't make it an entire hour less) they lost two years of efficiency in these three areas. We are just starting to understand the impact of sleep and how many areas it impacts. I suspect this area of research to have a huge boom in the near future (3-5 years).

So, how do we motivate our children and students? Students need optimal challenges, feedback from the task (rather than from the teacher), freedom from demeaning evaluations, a sense of autonomy, choices, and self-direction. In other words, they need more meaningful projects and less testing. Good luck getting this in traditional schools. There are certainly teachers out there who are doing exactly this for each of their students, but they are becoming more and more rare.

There is one other thing I feel I should mention here. The brain interprets rewards and punishments as a loss of control, which is demonstrated by the stress hormones being released in the brain. The brain is wired to try to find ways of getting the reward without doing the job/assignment. We should stop fighting this and change the way we are teaching. 80% of education in public schools is competitive. While this is motivating for the top few kids, it's extremely demotivating for the other 95% of students. Why try if you aren't going to win? Stop and think about this - 95% of students are being discouraged 80% of the time in school. In order to address this, our society keeps adding more tests and rankings. We are just making it worse rather than embracing the research and trying to help the students.
