Transcript of Concepts
Welcome to Concepts
The purpose of this presentation is to demonstrate how to teach a concept.A concept is a way of grouping several
abstract orconcrete objects, based on shared
characteristics.A concept might be a commonly found
object such asforks or silverware, or something less
tangible like facts.Once a concept is defined use examples to
help demonstrate the concept, and teach your
audiencehow to recognize what is applicable to
the concept.
Next
Generalization and
DiscriminationTwo skills that are essential to this process are
Generalization and Discrimination. Generalization is the process of removing irrelevant
details. Different forks may be made from different materialsbut the definition of a fork does not take note of material.
Discrimination is recognizing the essential details, ifthe utensil does not have multiple “teeth”, it is not a fork.
Students may over-generalize and not be “picky” enoughor under-generalize, and focus on irrelevant details.

Strategies
The two main strategies for teaching a concept are Inquiry and Expository.Inquiry presents the audience with multiple examples,
asking them to sort and theorize what the essential characteristics are.Expository presents the concept early on, clearly defining the definingcharacteristics, and then uses examples to reinforce those details.
In the following slides you will see an example using the Expository Method.

How to Introduce
Begin with a strong image to catch the interest.In this example we have an image containingmany vivid colors, both warm and cool.
Introduce the audience to the subject at hand,Color. “Some colors are described as warm,
others cool. Today we will discuss what that means.”
Next
Ease in-Past Knowledge
Remind the audience of past knowledge they havealready learned that is relevant to this concept.“Everyone has studied colors. Everyone knows thebasic 6; Red, Orange, Yellow, Green, Blue, Purple.And we have all seen how these 6 colors can manifest
in a variety of combinations and shades.”
Next
Define the ConceptDefine the concept clearly. Establish what attributes
make something an example of this concept, or not.
Warm colors are dominated by Red and/or
Yellow. These include Orange, Red, Yellow, and shades of Green.
Some colors are primary, the most basic, while others are a combination of two colors, or secondary and
tertiary.Different shades or pigments are created depending
on the ratios of those two colors. Cool colors are dominated
by Blue. These include Blue, Purple,
and some shades of Green.
An image is warm or cool when most colors in it is either warm or cool.

Help Them Remember
Try to offer any trick or method you know of to help remember the relevant attributes that
distinguishan applicable example from a “non-example”.
In this instance, you might suggest “warm fire” and “cool water”.
Next
The First ExamplesPresent two examples that are undeniable examples of
the concept, and in most cases, not the concept.In this case, two images that are definitely warm and cool.
Explain why these two examples fit the concept.
Warm Cool
The image on the right is a warm image because every color, other than black, is a warm color,
reds, yellows, and oranges, and these colors represent the color
majority.
In Contrast, this image is
dominated by blues and greens.
Next
Additional Examples
Next you provide the audience with multipleexamples, some of which do and some of whichdo not fit the concept, or in this case,
examples of warm and cool images.Ask the student to decide for themselves which
are warm and which are cool.
Next
Feedback
If possible try to provide feedback for your audience.In the case of a presentation, pose questions which are
designed so that in the process of answering themstudents evaluate their own methods of
determining what the concept is applicable to.
Next
ReviewReview the concept and the key attributes which
identity something as applicable. In this case, remindyour audience that warm colors are associatedwith the Yellow sun and the Red fire, because
warm colors have more Reds and/or Yellows, whilecool colors are associated with Blue water andthe shade of Green leaves because cool colors
have more Blues.
Next
Discussion/Utilization
Discuss how this new knowledge could be useful.In this instance, when creating an image or layout
the audience can consider what their goal is,and whether that goal is best served by a warm
or cool image.
