General Stress
• Everyone has this kind• It resolves itself in a day or two• No intervention required
![Page 6: Stress The human reaction to events in our environment. Wear and tear on our body](https://reader036.vdocument.in/reader036/viewer/2022081516/56649e305503460f94b20c24/html5/thumbnails/6.jpg)
Cumulative Stress

alleviate symptoms• You have more serious physical
symptoms• You have more serious mental
anguish

Acute Traumatic Stress
• Critical incident stress• Produces considerable
psychological distress• A normal reaction to abnormal
events
![Page 8: Stress The human reaction to events in our environment. Wear and tear on our body](https://reader036.vdocument.in/reader036/viewer/2022081516/56649e305503460f94b20c24/html5/thumbnails/8.jpg)

Stress
Effects of long term release of cortisol• Increased blood pressure• Inhibits inflammatory response• Suppresses immune system• Damages brain cells

Learning is Enhanced by Challenge & Inhibited by Threat
• The brain’s priority is always survival - at the expense of higher order thinking
• Stress should be kept to a manageable level
• Provide opportunities to “grow” and to make changes
• Have high, but reasonable expectations

Stress & LearningThe stress-brain loop
↓ Attention↓ Perception↓ Short-term memory↓ Learning↓ Word finding
Chronic Stress•Inadequate sleep•Poor nutrition•Emotional distress
Increases glucocorticoids
Decreased regulation of cortisol

Brain Organizes Memory In Different Ways
• Retrieval often depends upon how the information was stored.
• Relevancy is one key to both storage and retrieval
• Provide and get examples• Connect to what students know, what they are
interested in• Make learning meaningful
![Page 16: Stress The human reaction to events in our environment. Wear and tear on our body](https://reader036.vdocument.in/reader036/viewer/2022081516/56649e305503460f94b20c24/html5/thumbnails/16.jpg)
Memory• When objects and events are registered by several
senses, they can be stored in several interrelated memory networks.
• This type of memory becomes more accessible and powerful.
• Conversation helps us link ideas/thoughts to our own related memories. Students need time for this to happen!!– Storytelling - Conversations– Debates - Role playing– Simulations - Songs– Games - Films

Learning & Memory
Sensory Memory:
A sensory memory exists for each sensory channel:
• iconic memory for visual stimuli
• echoic memory for aural stimuli
• haptic memory for touch
Information sensory memory short-term memory by attention, thereby filtering the stimuli to only those which are of interest at a given time.

Learning & Memory
Short-term Memory:
• acts as a scratch-pad for temporary recall of the information under process
• can contain at any one time seven, plus or minus two, "chunks" of information
• lasts around twenty seconds.

Techniques to Help Memory
![Page 22: Stress The human reaction to events in our environment. Wear and tear on our body](https://reader036.vdocument.in/reader036/viewer/2022081516/56649e305503460f94b20c24/html5/thumbnails/22.jpg)
Techniques to Help Memory• Define the “gist” - OVERVIEW• Sequence events• Plot out pictorially the information• Tell the information to others in own
words - TALK– Peer teaching/tutoring
• Amplify by giving examples• Use multiple parts of the brain
(emotional, factual, physical)– Auditory, Visual, Kinesthetic, Talk– Combine
• Use color effectively– YellowYellow and orangeorange as attention-getters
![Page 23: Stress The human reaction to events in our environment. Wear and tear on our body](https://reader036.vdocument.in/reader036/viewer/2022081516/56649e305503460f94b20c24/html5/thumbnails/23.jpg)
The Brain is a Social Brain
• The brain develops better in concert with others
When students have to talk to others about information, they retain the information longer and more efficiently!
Make use of small groups, discussions, teams, pairings, and question and answer situations.
