  1. Teenage Brain Dr. Cherie Majorcmajor@uidaho.eduhttp://www.members.tripod.com/cheriemajor Educational Implications Based on the Frontline Video Inside the Teenage Brain

  2. Lobes and Basic Functions

  3. Nerve Cell

  4. Development • Chemical trail • Migration • Branch, prune and myelin • Vulnerable to environment

  5. Myelin

  6. Inside the Teenage BrainFrontline Part I • Rapid Frontal Lobe Development > 9-25 years • Proliferation and pruning > experiences lead to pathways developed > use it or lose it • Executive director • Organization problems • Don’t think about or worry about consequences • Drugs have a higher impact • Regulates mood (hormones and mood) • high risk most vulnerable • more access to things that harm Implications:

  7. EmotionsFrontline Part II • Teens process information in different regions of the brain than an adults • emotions – don’t assume they understand what you say or read emotions the same Implications:

  8. CerebellumFrontline Part III • Cerebellum coordinates movement and thinking • Thinking and memory are enhanced with complex motor tasks like exercise/dance/sports/cheers etc. • Implications:

  9. SleepFrontline Part IV • Sleep deprivation affects mood and performance - 9 1/4 hours Implications:

  10. RelationshipsFrontline Part V • Teens yearn for parents/teachers time – don’t want to ask - want to be noticed Implications:

  11. Memory Sensory memory taste/smell/sounds/touch/sight Working memory Rehearsal Long-term memory

  12. Rehearsal Visual/Sound/Write/Talk Relate to prior experience or real life (What is this like?) Create complex motor task Teach Review: minutes/hours/day/ weekly/month (rotate order- first/middle/last) Interdisciplinary Curriculum (interference)

  13. Sterile Environment

  14. Enriched Environment Larger frontal lobes Higher metabolic rate More glial cells

  15. Classroom Environment Stimulating artifacts/manipulatives/simulations Positive = motivation Negative = avoid Social interaction and application vs passive instruction High emotion enhances memory funny/sad stories/excitement

  16. Positive Emotions and Immune Functions • Viewing humorous tapes • Increased viral antibodies in saliva • Using humor as a coping strategy for stress has long term positive effect on immune system • Kathleen Dillon

  17. Test Anxiety • Sympathetic system for fight or flight (anxiety) • Blood Flow to Mid-Brain • Adrenaline/heart rate/blood to extremities • Para sympathetic system – reverse • Reduce Test Anxiety • Endorphins - exercise • 1st answer easy • answer known questions first • cheat sheet (small review card) • 5 minutes to look up answers

  18. Can you read this?

  19. Spelling Research • Reading is recognition Spelling is recall • Types –phonetically inaccurate/accurate • PA – Temporal Lobe /Auditory Trace • 1/3 French & English • Italian & Spanish ½ the rate • Visualize – spell backwards • Provide visual cues – don’t look up

  20. Females Verbal abilities Receptive language Productive language Analogies Comprehension Fluency Creative writing Males Visual-spatial Directions & shapes Mental rotation Maze & maps Geometry & Math Aiming and tracking Physically aggressive Sex Differences in Cognitive Abilities

  21. Male/FemalePerformance

  22. Brain organization within the sexes

  23. Testosterone

  24. Sensitive Periods
