Observable Behavior

A behavior which can be noted through one of the senses (seen, heard, tasted, smelled, or felt). Observable behaviors are usually described by action words such as touching, walking, saying, or writing. These do not include feelings or intentions which are inferred from other behaviors.

Measurable Behavior

In order to be measurable a behavior must first be observable. In addition, an observer must be able to clearly determine whether the behavior is occurring, count the occurrences of the behavior and/or time the duration of the behavior. Behaviors which have a discrete beginning and ending are the easiest to measure.

Even though the teacher may be interested in complex behavior problems or in students' feelings or attitudes, such as anger or sadness, these concepts are difficult to define and measure. By identifying specific observable and measurable behaviors associated with feelings, the teacher can more easily and accurately measure and record progress.

Examples:

Johnny talks to other students during silent reading.

This is both observable and measurable. We can hear and see Johnny talking and we can count the number of times Johnny talks or time the length of time that he spends talking.

Johnny has a poor attitude toward school.

It is not possible to determine exactly what Johnny is thinking. The teacher must rather identify exact behaviors which only infer Johnny's feelings about school.
