1 Complex Cognitive Processes

2 How do we learn concepts? Concepts: set of defining attributes -distinctive features shared by members of a category –Prototypes: best representative of a category –Exemplar: a speific example of a given category that is used to classify an item –Schemas: recognition of a concept –Simplicity principle: simplest category or rule

3 How can we teach concepts? Defining attributes and prototypes –Concept attainment: construct an understanding of specific concepts and practice skills and practice thinking skills Components needed: –Examples (prototypes), nonexamples –Relevant & irrelevant attributes –Name of concept –Definition –Use it (do exercises, solve problems, write, read, explain, etc)

4 Teaching concepts: »Through discovery »Through exposition

5 Teaching Concepts through Discovery Estructure: fundamental ideas, relationships, patterns of the field. Be active: identify the key principles; identify the interrelationships (discovery learning) Inductive reasoning: use specific examples to formulate a general principle. Intuitive thinking: make guesses based on incomplete evidence and then comfirm or disprove them.

6 Teaching Concepts through Exposition Use deductive reasoning: draw conclusions by applying rules or principles; move form general to specific. –Expository teaching: teachers perent material in complete, organized form, from broadest to more specific –Meaningful verbal learning: focused and organized relationships among ideas and verbal information Use advance organizers: statements of inclusive concepts to introduce and sum up material that follows –Comparative: organizers that activate working memory –Expository organizers: knowledge that students will need to understand the upcoming information Relate contect back to organizer: think how you could expand on the original advance organizer.

7 Learning Disabilities and Concept Teaching Use analogical instruction: identify knowledge that weak students already have in memory that can be used as a starting point for learning the new, complex material

8 Problem solving Problems: well-structured, ill-structured –Initial state –Goal –Path for reaching the goal Problem solving: a)General –Identify problems and opportunities –Define goals and represent the problem Focus attention Understand the words Understand the whole problem Translate the problem Represent the problem –Explore possible strategies Algorithms Heuristics: –Means-ends analysis –Working-backward strategy –Analogical thinking –Anticipate outcomes and Act –Look back and learn

9 Factors that hinder problem solving: Fixation: –Functional fixedness –Response sets Some problems with heuristics: –Representativeness heuristic –Availability heuristic –Belief perseverance –Confirmation bias

10 Effective problem solving Expert knowledge Novice knowledge

11 What's creativity? Myths about creativity: – People are born creative – Creativity is related with negative qualities – Creativity is a fuzzy, soft construct – Creativity is enhanced within a group

12 What is creativity? It's the ability to produce work that is original, but still appropriate and useful. – People are creative in particular areas. – Inventions must be intended – It should be applied to any subject – It often involves more than one person – It results in a new and useful product in a particular culture or situation

13 What are the sources of creativity? Creativity is the result of cognitive processes, personality factors, motivational patterns, background experiences, and social environments.

14 What do we need to be creative? Domain-relevant skills: talents and competencies valuable in the domain Creativity-relevant processes: work habits, personality traits Intrinsic task motivation: deep curiosity and fascination with the task Sometimes we need to incubate or restructure in order to be able to come up with a solution.

15 How can we assess creativity? There are two types of creativity tests: – Verbal: think and say – Graphic: create – These tests require two types of thinking: Divergent: proposes many answers Convergent: identifies only one answer – Responses to these tests score: Originality: fewer than 5-10 people/100. Fluency: number of different responses Flexibility: categories of responses

16 How can I identify creativity in my students? Curiosity Concentration Adaptability High energy Humor Independence Playfulness Nonconformity Risk-taking Attraction to complex and mysterious Willingness to fantasize and daydream Intolerance for boredom Inventiveness

17 Encouraging Creativity Accept and encourage divergent thinking Tolerate dissent Encourage students to trust their own judgment Emphasize that everyone is capable of creativity in some form Provide time, space, and materials to support creative projects Be a stimulus for creative thinking Encourage brainstorming Encourage play

18 The Big C: Revolutionary Innovation Who? Those who were explorers, innovators, and tinkerers. Warning: – Avoid turning intrinsic into extrinsic motivation – Avoid making him miss his childhood – Avoid making him so perfect that his rewards be lavish – Foresee possible psychological wounds

19 Learning Strategies and Tactics Learning strategies: general plans for approaching learning tasks Learning tactics: specific techniques for learning that make up the plan

20 How to get students to use learning strategies? 1.Teach them different strategies as well as specific tactics (mnemonics, skimming, writing answers to possible questions) 1.Teach them when, where, how, and why to use them 1.Develop the desire to use these skills 1.Teach students using such strategies

21 How can students get learning strategies into action? Decide whats important: focus attention, find the central idea, identify headings, bold words, outlines, an other indicators to identify key concepts and main ideas. Use summaries: find the topic sentence, identify big ideas, find supporting information, delete redundant information. Underline and highlight: be selective and transform the ideas into your own words. Dont use the books words. Note conections and draw diagrams. Take notes: translate, connect, elaborate, and organize the information. Dont get distracted from the lecture with your note taking. Find key ideas, concepts, and relationships

22 How can we organize information? Use graphic organizers such as maps or charts Map relationships Use Venn and Tree diagrams

23 What strategies can we use when we read? R eview chapter E xamine words A sk what you expect to learn D o it! S ummarize When reading literature: C haracters A im P roblem S olved it? K now W ant to know L ike to know

24 How can I make sure my students use learning strategies? Make sure the learning task is approppriate. Do your students care for learning and understanding? What are their goals? (value learning) Your students must believe that the effort they invest is reasonable and worth it. Do they think they will make it? (effort and efficacy) What do your students believe about their own learning and strategies? (epistemological beliefs) – Structure of knowledge – Stability/certainty of knowledge – Ability to learn – Speed of learning – Nature of learning

25 Teaching for transfer Low-road transfer – Direct-application transfer High-road transfer – Forward-reaching – Backward-reaching

26 Teaching for Positive Transfer Avoid situated learning Decide what is worth learning Be aware of what the future is likely to hold for your students Use overlearning to make sure your students will master a skill Create powerful teaching- learning environments

27 How can we transfer strategies? Acquisition phase: students should receive instruction about a strategy, be told how to use it, and rehearse it Retention phase: practice and feedback Transfer phase: provide new problems that can be solved with same strategy Point out how this will help students to solve many problems and accomplish many tasks
