Teaching concept analysis
The following information is from Unit 19 of the book Teaching: A Course in Psychology by Wesley C. Becker, Siegfried Engelmann, and Don R. Thomas.
Note: Science Research Associates published the book in 1971. I am unsure if the publishers reprinted the book or if it is available to buy. I found it through a university inter-library loan program. I suspect that Becker or Engelmann use the book or some form of it in their special education teaching classes at the University of Oregon.
- Discriminate or differential responding: in the field of learning, it refers to evidence of responding one way to one class of stimuli and responding another way to another class of stimuli
- Stimulus generalization: when a person responds to a new stimulus in the same way he responds to a previously taught stimulus that has similar characteristics
- Example: calling red things “red” and blue things “not red” and then calling orange things “red” also
- Three factors cause generalization
- The number of identical stimulus characteristics
- The number and magnitude of the difference in concept characteristics between two concepts
- The degree of prior discrimination training with concept differences
- If you can predict when stimulus generalization may occur, you can prevent or plan for the difficulties
- Analysis of concept universes
- Basic concept domains show that concepts from one domain do not share characteristics with concepts from another domain
- Concept domains
- Objects (living things, man-made things, etc.)
- Object properties (mass, heat, state, structure, parts, shape, size, color, surface properties, etc.)
- Events in time and space (conservation of mass, movement, change in energy, change in group composition)
- Relationships among events in time and space (cause and effect)
- Casual relations
- Teach lower-domain concepts before higher-domain concepts
- Example: teach what a car is before you teach the color red or the student may think that when you show a red car and say it is red, the student will think that “red” means car
- Example: the student should know the names and characteristics of things being taught for relative size
- The idea is to teach the lower concepts with concept instances and non-examples
- Then teach more complex concepts in comparison to the simple concepts
- Concept hierarchies: lower order concepts are joined together to form higher order concepts
- A higher concept has more instances (examples) than a lower concept
- To teach a hierarchy you teach concepts from two levels at the same time
- Example: to teach about mammals, teach mammals and not-mammals
- Then teach sub-groups of mammals
- Teaching two levels teaches:
- How concepts are related and teaches
- How one concept can be an instance of another concept
- Related concepts and instances need to be carefully discriminated
- Concept analysis examples
- Two concept pairs (S+) and (S-) and two other groups of concepts
- Concepts whose characteristics are irrelevant to the central concept instances (Si)
- Higher-order concepts whose characteristics are common to the two concepts being analyzed (Sc)
- Horses vs. dogs example
- Differences
- Horses (S+): hooves, large, mane, whinny
- Dogs (S-): paws, small, no mane, bark
- Irrelevant stimuli (Si)
- Higher order characteristics common to S+ and S- (Sc)
- Both: Mammary glands, four legs, move, grow, living
- Police dog vs. wolf
- Differences
- Dog (S+): bark, small, dull teeth
- Wolf (S-): no bark, big, sharp teeth
- Irrelevant stimuli (Si)
- Higher order characteristics common to S+ and S- (Sc)
- Both: canines, colors, move, grow, living
- Dog vs. tree example
- Differences
- Dog (S+): dog shape, move, noise, legs
- Tree (S-): tree shape, no moving, no noises, branches
- Irrelevant stimuli (Si)
- Higher order characteristics common to S+ and S- (Sc)
- Square vs. triangle example
- Differences
- Square (S+): 4 angles, 90 degree angles
- Triangle (S-): 3 angles, variable angles
- Irrelevant stimuli (Si)
- Both: size, position, color, surface pattern
- Higher order characteristics common to S+ and S- (Sc)
- Both: closed figures, straight sides
- To teach concepts
- If there are many differences between S+ and S-
- Teach some differences
- Example: dog and tree
- If there are few differences between S+ and S-
- Teach all differences
- Example: dog and wolf
- Common characteristics (Sc)
- Likewise teach more discriminations from S+ to S- if the concepts have few differences
- Irrelevant characteristics (Si)
- Make sure to teach most concepts in different angles or positions just in case a student may think that location is relevant
- Higher order concepts have more irrelevant characteristics
- The ratio of essential characteristics to irrelevant characteristics shows how abstract a concept is
- Example: the more Si and the less S+, the more abstract
- After you analyze the concepts you want to teach, you can group concepts
- You can determine what is higher-order
- You can determine teaching sequences
