How to do concept teaching

The following information is from Unit 20 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.
  • Review: concept learning discriminates S+ from S- and both of these from Si
  • Every concept characteristic has a value or range of values
    • Fixed if only one value
      • Example: 4 angles is a fixed characteristic of a square
    • Range of value if more than one value
      • Example: Many angles are a range of value for many figures
      • The range needs to be defined
    • S+ and S- are a set of values that are instances of some high-order concept
      • Si characteristics are another set by themselves or are independent of what is being taught
        • Example: any instance of shapes can be shown to present instances of color
    • The teacher shows what characteristics are irrelevant and what are the range of relevant characteristics
  • Ways to structure teaching sequences
    • Teach the characteristic that leads to less possibilities available
    • Switch from an instance to a non-example so that only one characteristics changes a a time
      • You can do this repetitively by using different sets of irrelevant characteristics one at a time
      • Good for teaching physical concepts
        • Example: “the ball is ON the char. The ball is now NOT ON the chair.”
    • Present a series of instances or non-examples where nothing changes but the range of characteristics to teach a range of S+ or S-
    • Present of series of instances where the Si change and S+ stay the same to teach the range of Si
  • Misrule: teaching something inessential to a concept
    • Example: only showing brown dogs when teaching the concept “dog”
      • The student may think that dogs are only brown
    • Misrules happen when:
      • There is no range of S+
      • If an irrelevant characteristic in Si is not varied
  • Avoiding memory load problems
    • Do not present too much information at once
    • Use pairs of instances you can compare directly
    • Change one thing when going from instance to non-example
    • Change one thing when going from instance to instance
    • Change one thing when going from non-example to non-example
    • Quickly present a sequence of instances
  • Language to teach concepts through prior knowledge
    • Use verbal rules
      • A rule has no irrelevant characteristics
    • Concepts that are more complex
      • Use a verbal rule to describe how people use them
        • Example: “a VEHICLE takes you places”
        • Example: “FOOD is something you eat”
    • Teach two levels of living things or objects with language
      • Example: “Here is a horse” (show a picture)
        • “The horse is brown”
        • Vs. showing the picture and saying “brown”
      • Example: “Here is a cup” (show the cup)
        • “A cup has a handle” (point to it)
          • Vs. “This is a handle” (point to it)
          • To say “A cup has a” eliminates confusion on what handle might be
        • “A cup has a bowl” (point to it)
