Take-Off Learning Picture

Return to Home Page Learning Pictures Menu Previous picture | Next picture

Learning Picture Name = Take-Off.

Frequency of Correct Responses = Accelerating toward correct frequency aim.

Frequency of Error Responses = Maintaining above Record Floor; not moving toward frequency aim.

Accuracy Ratio = Increasing.

Change to Make = Drill the Errors.

Situation Report

Metaphor: Children back in the 1970s named this learning picture "Take-Off" because the correct frequencies are "taking off" upwards, perhaps like an airplane taking off. The corrects accelerate. The errors, however, are maintaining, above the Record Floor. Pat All reported on the learning pictures and their names (All, 1977). Likewise, that same year Dr. Ogden R. Lindsley (1977) presented learning pictures to the MABA convention.

Description: "Take-Off" may represent a desired learning picture. It does show improvement in the frequency of correct responding, and to accuracy. However, it has no error learning. The corrects accelerate up toward some correct frequency aim. The errors do not head toward an error frequency aim.

A "Take-Off" picture may emerge as the end stage of a "Crossover Jaws" picture. Unlike a "Climb" picture, however, in Take-Off some errors persist. A Take-Off picture also illustrates that accuracy is independent of frequency. The accuracy increases, even though the errors do not decrease!

Decision: If a "Take-Off" learning picture emerges, that means some errors are presenting difficulty. The decision to make is to drill the errors.

Notes: The Record Floor represents the amount of time spent recording the behavior of interest. We define it as 1/number of minutes spent recording. On the chart we use a dashes to show it. If the Record Floor stays the same every day, then a dashed line (as shown above) can be used. "Zero" per minute is shown by frequencies plotted just below the Record Floor. All standard celeration charts should have a Record Floor.

The chart shown above represents a likeness only of a standard celeration chart. The chart shown above is also a "stylized" chart. That means that I constructed it for teaching and illustrative purposes only. It does not show real data. The celeration lines range through more chart cycles than one typically finds.

Dr. Ogden R. Lindsley invented the Standard Celeration Chart, founded Behavior Research Company, and has been the main proponent and developer of both Precision Teaching and standard celeration charting.
