Mid Level Learning Picture

Mid-Level Learning Picture

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

Learning Picture Name = Mid-Level.

Frequency of Correct Responses = Maintaining below correct frequency aim.

Frequency of Error Responses = Maintaining above Record Floor and above error frequency aim.

Accuracy Ratio = Maintaining.

Change to Make = Step Way Back in the Curriculum.

Situation Report

Metaphor: Children back in the 1970s named this learning picture "Mid-Level" because both the correct and error frequencies are maintaining at the middle of the chart, or midway between the aim star for the corrects and the aim star for the errors. 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: "Mid-Level" generally represents an undesired learning picture. It shows no improvement in the frequency of either correct or error responding. However, it shows no learning. The corrects are not moving upward to a correct frequency aim. Nor are the errors moving down to an error frequency aim.

A "Mid-Level" picture shows no change and thus no improvement in accuracy. The Accuracy Ratio remains the same.

Decision: If a "Mid-Level" learning picture emerges the decision to make is to step way back in the curriculum.

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.
