The Adolescent Brain David H. Vawter (vawterd@winthrop.edu). Dave Vawter, B.S., M.Ed., Ph.D, D.A.D “ This too shall pass”. Brainy Facts: What do we know about the brain?. Adult = 3 pounds 2% of our body weight but consumes 20% of our calories 70% water, it consumes 30% of the water we drink.

Brainy Facts: What do we know about the brain? • Adult = 3 pounds • 2% of our body weight but consumes 20% of our calories • 70% water, it consumes 30% of the water we drink
The brain develops from the back towards the front. Beginning at the Cerebellum, then the Amygdala, the Basal Ganglia, the Corpus Callosum and then last the Prefrontal Cortex.
Used MRI to scan the brains of nearly 1000 healthy children ages 3-18. Between ages of birth-2 and 9-10= tremendous growth of neurons Ages 2-3 and 11+= massive pruning Dr. Jay Giedd, Neuroscientist
Fewer but faster connections The grey matter continues to thicken, Used connections will flourish, unused will die. During adolescence…use it or lose it
Brain Break • Rally Robin
Problem solving Judgment Planning Organization Self-monitoring Emotions Attention Concentration Awareness of abilities Self-control “do the right thing” Frontal Lobe
The CEO of the Brain • The frontal lobes: executive decisions and moral/ethical control • Development continues from back to front through early 20’s • “It’s sort of unfair to expect teens to have adult levels of organizational skills or decision-making before their brains are finished being built.”- Dr. Giedd
Teens relied on the amygdala, associated with emotion and gut reactions Teens see anger when it was not intended Everything is not as it seems to them…..
But what if the student is very smart? • ..\body\brain\Emotion_(Amygdala)_and_Intellect_(Frontal_Cortex)__Analyzing_the_Brain_of_a_Teenage_Genius.asf
They need 9 ¼ hrs… They get…6-7….! The biological clock shifts in the teen years Sleep deprivation can have a major negative effect on learning and memory! Turn off backlit devices an hour before bed Catching ZZZZZZs
ADD/ADHD? Does the teen have…… • Ability to "hyperfocus" • Above average intelligence or higher • Creative thinking • The inability to focus causing problems with grades, relationships, safety, self-esteem • Famous people: Albert Einstein, Will Smith, Walt Disney, Ben Franklin, Whoopie Goldberg
How do you help the ADD/ADHD student? • Remove clutter even from walls • Allow movement, sit in the back or side • Do not get angry at their behavior; that will never fix the problem • Give extra time if noticeably distracted • Keep a stash of their materials in your room; help them with organization
Drugs and alcohol can alter normal development of the brain Teens who drink are exposing their brains to the toxic effects of alcohol at a critical time of brain development During adolescence… period of high risk Image from Susan Tapert, PhD, University of California, San Diego. http://www.sfn.org/skins/main/images/brainbriefings/bb_Oct2002_large.gif
What about students from poverty? TEACHERS MAKE A DIFFERENCE!!
Neurogenesis-the birth of new neurons • Evident in the hippocampus and perhaps in the cerebral cortex. • New neurons develop from neural stem cells that remain in our brains throughout life. • Continual turnover of neurons - old ones die and new ones are born - and these new neurons can participate in circuits that underlie learning.
Common Factors in the Lives of Low SES Kids! Neurogenesis is the raw material for learning!
Chronic Stress … 1. Creates emotional problems (Burgess et al. 1995) 2. Lowers IQ, reading scores (Delaney-Black, et al. 2002) 3. Causes Memory loss (Lupien, et al. 2001) 4. Shortens dendrites (Cook and Wellman, 2004), (Brown, et al. 2005) 5. Causes neuron death (De Bellis, et al. 2001) 6. Fosters inappropriate attachments Schore, A. 2002)
Arnsten AF. (2010) Stress signaling pathways that impair prefrontal cortex structure and function Under High Stress, Brains Engage in Bottom-Up Decision-Making for a More Reflexive Strategy “What were you thinking?”
Teachers who criticize, hold negative attitudes and use sarcasm as classroom discipline will activate the fear and stress areas of the student’s brain. This activation alters the student’s ability to think and learn.
Crucial time in brain development Willful pigheadedness? Making mistakes Providing structure, helping them get organized, making our content relevant, getting them involved in learning What does this mean for EDUCATORS?
SUMMARY: Brains Can Change for the Better • Brains physically change every day • Targeted classroom teaching can make dramatic changes in days • DNA is not your destiny • Teachers are the strongest change agent in student’s lives
Brain Break The Adolescent Brain -Part Two: Strategies for the Classroom
Movement Organization Novelty Communication Relevance Choice Feedback Relationships
Work in Groups! • Plan • Select with partial choice • Let them use GoogleDocs to create presentations • They create the assessment
Novelty • Dress Up • Change the room around • Go outside!!!
Speed Teaching!The Six R’s • Reflexes • Reflection • Review • Reteaching • Relevancy • Ready for what is next
Reflexes • TPR • Hand Checks • Movement
Reflection • Long term retention
Review • Not how many times…..
Reteaching • Differentiation
Relevancy • Two Kinds • To their lives • Why
Ready • Cognitive Dissonance • Anticipation
When they get to be about 25, they’ll realize their parents and teachers were pretty smart people.
