Day 20: Transfer, Problem Solving Flashcards

1
Q

Gick & Holyoak tried 3 ways to induce transfer

A
  • Subjects were told to summarize story in abstract terms
  • A general principle was provided
    • “If you need a large force to accomplish some purpose, but are prevented from applying such a force directly, many smaller forces applied simultaneously from different directions may work just as well”
  • Create a diagram

Q

What worked?

A
  • All 3 ways (summary, general principle, and diagram alone) failed to facilitate transfer
  • Subjects were given the two stories and told to write down the basis for the similarity in the story
    • This worked!
    • It’s known as analogical problem solving

Q

Gick & Holyoak’s Conclusions

A

Gick and Holyoak concluded that analogical problem solving depends on three steps:

  • Noticing that an analogical connection exists between the source and the target problem
  • Mapping corresponding parts of the 2 problems onto each other (fortress= tumor, army= ray)
  • Applying the mapping to generate a parallel solution to the target problem (using small groups of soldiers from different directions= sending several weaker rays from different directions)

Q

Contemporary Perspective

A
  • Transfer is a specific process, not a general one
  • Learning occurring at one time can facilitate learning at another time if, in the process, the individual learns how to learn
  • Learning processes may not be the only thing to transfer
    • Emotions and motivation may transfer too (Ex. Little Albert, PTSD)

Q

Transfer from various theoretical perspectives

A
  • Behaviorism: Generalization (i.e., responding in same way to different stimuli because of similarity)
  • Information Processing: Encoding information in a way that information or skills can be recalled in appropriate contexts
  • Social Cognitive Theory: Latent learning; certain actions will lead to favorable outcomes in other contexts
  • Situated Cognition: Transfer is unlikely to occur from one context to another context

Q

What facilitates transfer?

A
  • Meaningful learning vs. rote learning
  • Thoroughness of learning process (less is more)
  • Similarity of situation/context/problem type
  • Practice!
  • Brief time interval between original and transfer task
  • Setting up a classroom culture that expects transfer

16
Q

Far Transfer

A
  • Old and new contexts are not similar; little overlap between situations
    • Ex: A teacher using skills developed in running a classroom to running a business
  • Usually requires analysis, deep thinking and seeing similarities that are not always apparent (ex. analogical problem solving)
17
Q

Near vs. Far Transfer Examples

A
  • N: Practice test -> Real test
  • F: Statistics Test -> Using software to analyze data for research
  • N: Driving a Ford pickup truck -> Driving a Chevy pickup truck
  • F: Driving a speedboat -> Sailing a sailboat
  • F: Typing on a typewriter -> Typing up Braille
  • N: Typing on a typewriter -> Typing on a computer
18
Q

Low Road Transfer

A
  • Transfer of well-established skills happens in an automatic or nearly automatic fashion
    • Ex: Taking a multiple choice exam in multiple contexts and domains
19
Q

High Road Transfer

A
  • Purposeful and effortful formulations of ideas about relations and connections among contexts
    • Ex: Using knowledge of chess strategy to become an effective politician
20
Q

Near/Far vs. Low-Road/High-Road

A
  • Near vs. Far: Primarily focus on the degree of similarity between the original task an transfer task, as well as contexts
  • Low-Road vs. High-Road: Refer to mechanisms of transfer (i.e., how a person approaches the situations: Is it more automatic? Or is there a conscious search for connections?)
21
Q

Well-Defined vs. Ill-Defined

A
  • Well-defined problems
    • Clear goals
    • Only one correct solution
    • Structured procedures for reaching a solution
    • All information is specified
    • Ex: How to get a car to mechanic after an accident/ How to earn enough money for down-payment on house/ Chess
  • Ill-defined problems
    • Ambiguous goals
    • More than one solution
    • No generally agree-upon strategy for reaching a solution
    • One or more features of the problem are not specified or are ambiguous
    • Ex: Writing poetry/ Cleaning your apartment (could be well defined if limits set)/ Learning to play guitar
22
Q

3 Parts of a Problem

A
  • Goal: Desired end state
  • Givens: What you are told at the beginning; your starting state
  • Operations: Actions that you can perform to reach the goal, including the rules of the game and how to get from one state to another
23
Q

Well-Structured Problem-Solving Process

A
  • Identify the problem goal
  • Represent the problem
  • Select a strategy
  • Implement the strategy
  • Evaluate the results
24
Q

Represent the Problem

A
  • Stating in more familiar terms
  • Relating to previously experiences problems
  • Represent visually
25
Q

Select a strategy, and Implement

A
  • Trial and error
  • Insight
  • Heuristics vs. Algorithms
  • Brainstorming
  • Means-End Analysis
  • Working Backward
  • Drawing Analogies
26
Q

Trial and Error

A
  • Thorndike’s Puzzle Box
  • Trial and error is something we use
    • Not effective or reliable
27
Q

Insight

A
  • A sudden awareness of a likely solution
    • An Aha! moment
  • Research has found 4 steps for insight to occur:
    • Preparation (time to learn and gather information)
    • Incubation (time to think)
    • Inspiration (Eureka!)
    • Verification (time to test)
28
Q

Silveira (1971): The cheap necklace problem

A
  • “You are given four separate pieces of chain that are each 3 link in length
  • It costs 2 cents to open a link and 3 cents to close a link
  • All links are closed at the beginning of the problem
  • Your goal is to join all 12 links of chain into a single circle at a cost of no more than 15 cents
  • Control group: Worked on the problem for half an hour
  • Experimental group 1: Worked for half an hour, interrupted by a half-hour break in which other activities were performed
  • Experimental group 2: As 1, but with a 4 hour break
29
Q

Heuristics and Algorithms

A
  • A heuristic is a mental shortcut
    • General method for solving problems that uses rules of thumb, which usually lead to a solution
    • Informal, intuitive, speculative strategies that sometimes work
  • An algorithm is a sequence of operations that when repeated over and over again guarantees success
    • Methodical, but often slow
    • If you get stuck or forget a step, you can’t move on
30
Q

Other methods

A
  • Brainstorming: Generating large number of possible approaches without regard to practicality then evaluate for usefulness
  • Means-end Analysis: Break problem down into 2+ sub-problems to solve
  • Working Backward: Start at problem goal and work in reverse toward initial problem state
  • Analogies: Drawing an analogy between the current problem and another previously solved problem can provide insight (Fortress/Tumor)
31
Q

Evaluate the Results

A
  • “Stop and think about it” step

- Check for evidence that confirms or contradicts your solution

32
Q

Problem-Solving Paradox

A
  • School tends to teach well-defined problems

- In real life, we face problems related to money, careers, social relationships, and happiness that are ill-defined

33
Q

Problem-Based Learning (PBL) (Cindy Hmelo-Silver)

A

Active approach to learning in which learners collaborate in understanding and solving complex, ill-structured problems

34
Q

PBL Example

A
  • Mr. Ho was a 60 year old machine operator in a garment factory who had enjoyed good health previously.
  • He has married and had a son and a 4 year old grandson.
  • The family had lived for 15 years on the 4th floor of a public housing estate with no elevators
  • Mr. Ho visited his family physician and complained of discomfort in both knees, worse on the right side
  • Each morning, he had to walk to the bus stop to get to work
  • In the past few months, he had found this increasingly difficult, particularly when he was walking down the stairs
  • Additionally, he was not spending as much time playing with his grandson as he used to
35
Q

In Summary

A
  • Transfer is one of the most hotly debated, yet important, issues in education
    • Does it happen? How? Under what circumstances? How can we facilitate it?
  • Problem solving is a complex process, but it is the foundation of learning and functioning in the world
    • Ill structured vs. well structured
    • In real world problems, there are well structured pieces to ill structured problems
      - Problem solving is a very specific form of transfer
    • It’s goal-directed, with a specific end in mind
