A comparison of data collection techniques used with discrete trial teaching
Section snippets
Participants
Adult participant: The researchers evaluated the ability of three behavior therapists to implement DTT and take data across three data systems throughout the course of the study. The therapists all had at least a bachelor's degree in psychology or in a related field and had been working in the field of applied behavior analysis an average of 4 years. Therapist 1 was a 25-year old female who held a Bachelor Degree; she had 3 years of experience in the field of ABA and 36 months working for the
Accuracy of data collection
We first evaluated the percentage of agreement between the researcher and the adult participant during sessions of discrete trial teaching across three different measurement systems. The adult participants implemented a total of 5298 teaching trials across the three measurement conditions. The overall percentage agreement between the researcher and the adult participant for the child participants’ correct responding across all research sessions was 84% for continuous recording, 72% for
Discussion
This study investigated and compared three different data systems in regards to their accuracy, efficiency, and user preference. On most, but not all measures, the continuous recording was the most accurate, with time sampling less accurate, and estimation data, relatively speaking, the least accurate. On one of the accuracy measures, consisting of point-by-point comparison between continuous recording and time sample, the latter was more accurate. It should be noted that anecdotal report
