Narrative Information to Inform Data Collection

Anecdotal observation shares a teacher's fleeting observation. Websterlearning


An Anecdote is a narrative told from the point of view of an observer. Anecdotal evidence is considered unreliable and is seldom acceptable as a means to validate an educational method or technique. Still, anecdotal evidence can be helpful when assessing a student, especially a student with behavioral issues. A starting point for a behavioral intervention is anecdotes, especially anecdotes collected by several different observers.

Sometimes those anecdotes are written in an ABC form, or Antecedent, Behavior, Consequence, a way in which the function of the behavior can often be identified. By observing the events or setting of the behavior being observed, by describing the behavior and figuring out the consequence, or benefit the student receives.

Problems with Anecdotes

Sometimes observers are subjective, rather than objective. Learning to observe the topography of a behavior without making any judgments about the behavior is often difficult, since culturally we tend to freight certain behaviors with meaning that may not actually be part of the behavior. It may be important that the person assessing the student begin with an "operational" definition of the behavior so all observers are clear what they are looking for. It is also important to train observers to name certain behaviors explicitly. They may say that a student stuck his or her foot out.

They may say it appears that they did it in order to trip another student, so it could be aggression, but you don't want to say "John intentionally tripped Mark" unless John tells you it was intentional.

Multiple observers do, however, give you varied points of view, which may be helpful if you use an "ABC" format for your observations.

Discerning the function of a behavior is one of the principal reasons for collecting anecdotal evidence, although discerning what is objective and what is subjective is often challenging. Figuring out which anecdotes are influenced by prejudice or expectation will help cull valuable information. Parents anecdotes will provide information, but may be shaped by some denial.

Examples: As Mr. Johnson began to plan for the Functional Behavioral Analysis he needed to do for Robert's disruptive behavior, he reviewed a number of anecdotal reports that were in his file from content area classes.
