Metacognition and Self-Regulated Learning

Metacognition

• Metacognition is awareness and understanding of one's own thinking and learning processes.
• The brain actively thinks about how it works.

The Metacognition Cycle

• The metacognition cycle is guided by self-regulated learning components.
• This cycle includes assessing tasks, reflecting on the task, applying strategies, and evaluating strengths and weaknesses.
• It's a cyclical process, meaning it's not necessarily linear.

Self-Regulation

• Self-regulation is self-control/management.
• It's the degree to which someone controls their behavior, thoughts, and feelings.
• Self-regulated learning has several steps:
  • Forethought phase: Task analysis, goal setting, strategic planning, self-motivation beliefs, self-efficacy, outcome expectations, interest/value, learning goal orientation.
  • Performance phase: Self-control, imagery, self-instruction, attention-focusing, task strategies, self-observation, self-experimentation.
  • Self-reflection phase: Self-judgment, self-evaluation, causal attribution, self-reaction/affect, adaptive/defensive reaction.

Elements of Self-Regulation

• Setting standards and goals, understanding what one wants to achieve.
• Self-observation, identifying strengths and weaknesses in behavior.
• Self-evaluation, determining how one feels about their behavior.
• Self-reaction, including reinforcement/punishment based on self-evaluation.
• Self-reflection, making adjustments to goals and behaviors.

Self-Regulated Learning Components

• Goal setting: Identifying learning goals.
• Planning: Time management techniques, prioritizing challenging concepts over easy ones.
• Motivation: Self-efficacy, maintaining discipline, controlling self-reaction and attention control.
• Learning Strategies: Effective goal-relevant learning strategies.
• Monitoring: Checking knowledge.
• Seeking Help: Knowing when to seek help.
• Evaluation: Analyzing personal progress towards goals.
• Reflection: Evaluating strategies used to identify areas for adjustment.

Effective Learning Strategies: Reading

• Identification: Determining key information (important points, graphs, tables, illustrations).
• Elaboration and Questioning: Connecting new information to prior knowledge, asking questions.
• Organization: Utilizing outlines, concept maps, or diagrams to structure information.
• Application: Considering how learned information can apply to various situations.
• Clarification: Identifying and resolving unclear points.
• Evaluation: Assessing personal understanding through self-reflection.
• Summarization: Condensing key concepts in one's own words.

Effective Learning Strategies: Note-Taking

• Importance: Helping focus attention, encoding auditory information, creating external memory.
• Content: Capturing main ideas, supporting details, personal connections/thoughts, summarizing information in your own words.

Comprehension Monitoring

• Danger: Stopping learning because of an illusion of knowing.
• Solutions: Using metacognitive techniques and self-regulated learning strategies.

Brain Basics: Brain Cells

• Glial cells: Supporting neurons (9:1 ratio), aiding nervous system development and repair, managing nutrient flow, insulating and speeding signal transmission.
• Example: Myelin sheath

Brain Cells: Neurons

• Neurons: Sending and receiving electrochemical messages (neural firing).
• Neuron parts: Dendrites (receiving), Soma (cell body), Axon (transmitting electrical signals), Myelin sheath (speeding up transmission), Nodes of Ranvier (allowing signals to jump), Synaptic terminal (sending chemical signals), Synapse (gap between neurons).

Neurotransmitters

• Neurotransmitters: Chemical messengers in the brain.
• Examples: Acetylcholine (learning), Dopamine (pleasure), Serotonin (mood), GABA (calming), Endorphins (euphoria), Glutamate (memory).

Neuron Communication

• Neurotransmitter accumulation in the synapse triggers action potential (all-or-none effect).
• Action potentials are equal in size.
• No "small" or "large" potentials

Brain Basics: Brain Parts

• Forebrain: Largest, most complex brain structure.
• Lobes of Brain: Four lobes (frontal, parietal, temporal, occipital) in each hemisphere.
• Subcortical features: Thalamus (relaying sensory info), Limbic system (hippocampus - learning, memory, spatial coding; amygdala - emotional processing).

The Four Lobes of the Cerebral Cortex

• Frontal lobe (motor control, problem-solving, speech).
• Parietal lobe (touch, body orientation, sensory discrimination).
• Temporal lobe (auditory processing, language, memory retrieval).
• Occipital lobe (visual processing).

The Hemispheres

• Lateralization: Each hemisphere is associated with specific functions.
• Left Hemisphere: Language, verbal memory, logic, math (analytic thought).
• Right Hemisphere: Spatial reasoning, nonverbal memory (visual), face recognition (intuitive thought).

Development of the Brain

• Receptor Site Changes: Long-term potentiation (LTP) and long-term depression (LTD) influence neuronal responsiveness.
• Enriched environments: Lead to more synapses, neuron growth/survival, link between cognitive stimulation and positive outcomes.
• Differentiation: Neuron specialization, becoming specialized.
• Myelination: Process of coating axons with myelin, increasing transmission speed.

Sensitive Periods vs. Critical Periods

Sensitive periods: Gradual changes associated with the organism's heightened sensitivity to external stimuli. These are important for development of a specific skill. Critical periods: Fixed time intervals associated with the organism's abrupt heightened sensitivity to external stimuli, crucial for developing a particular skill. The brain's allocated cortical areas adapt to the specific skill.

Expectant vs. Dependent Plasticity

• Expectant plasticity: Normal experiences shape brain development (e.g., language acquisition).
• Dependent plasticity: Formal training needed for acquiring specific skills (e.g., reading, writing).

Neurological Basis of Learning

• Neurogenesis: Growth of new neurons.
• Consolidation: Synaptic consolidation (quick strengthening of synapses), systems consolidation (long-term organization of neuronal networks). Key components involved include the hippocampus, organizing memory components across the cortex.

Brain's Role in Learning: Overview

• The brain is plastic and adaptable.
• Specialization within the brain (lobes, hemispheres).
• Experiences are important (e.g., healthy environment, nurturing, appropriate stimulation).
• Learning builds on prior knowledge.
• Learning is an active process.
