Welcome to the Standard Chart Topics Site

Welcome! I created this website to highlight several topics germane to Standard Celeration Charting and Precision Teaching. Accordingly, this site focuses on the Standard Celeration Chart:

Invented by Dr. Ogden R. Lindsley and his associates, the Standard Celeration Chart forms the foundation for Precision Teaching. The chart comes in several versions. The most common version has "SUCCESSIVE CALENDAR DAYS" along the x-axis. We refer to that chart as the "Daily Behavior Chart." Up the left, or y-axis, one finds a multiply-divide scale of frequency. This scale has the label "COUNT PER MINUTE." Frequency refers to "number per minute." So, one uses the chart to plot the frequency of behavior on a daily basis.

As frequencies accumulate across a chart, one can draw a line of best fit through them. This line forms a "celeration line." Celeration shows trends in frequency. The frequencies may speed up, slow down, or stay the same. Beyond simply describing the frequency and celeration of behavior, one may use standard charts for instructional decision-making. Such decisions place the chart in a vital and critical role.

Several different types of celeration lines can be drawn through a set of frequencies on the chart. Dr. Ogden Lindsley has described at least six such celerations. The "six celerations" form the first major topic discussed here.

Next, precision teachers often count and chart both the daily frequency correct and the frequency error for a particular movement cycle, or behavior of interest. We call that an accuracy pair, or a "fair pair." As both correct and error frequencies accumulate across the chart a behavior change picture emerges. We call such results "learning pictures." A full set of learning pictures may be described with different combinations of celeration lines. One may use learning pictures to make instructional decisions. This includes decisions about when to make changes, and what sorts of changes one should make in order to achieve the desired results. Thus, "learning pictures" form the second major topic presented here.

Purpose: This website stands as a scientific and technological resource in support of Standard Celeration Charting and Precision Teaching. It therefore has no commercial purposes.

Caveats and Limits: This website is for noncommercial, educational resource and illustrative purposes only. It was not created for the purposes of teaching standard charting or Precision Teaching. To learn how to chart, and to learn how to do Precision Teaching, one will have to find and make use of resources developed for that purpose.

The charts shown on this site are representations and approximations of Standard Celeration Charts. Therefore, they are likenesses only. They are not actual Standard Celeration Charts. They are too small to be used as actual charts (intentionally so). They likewise have some other differences from actual Standard Celeration Charts. Therefore, they should not be used as replacements for actual charts.

No warranty is made, either explicitly or implicitly, regarding the information presented on this website.

Dr. Ogden R. Lindsley invented the Standard Celeration Chart, and was principally responsible for developing Precision Teaching.
