Effects of conducting peer behavioral observations on the observer's correct use of discrete trial teaching procedures

•Peer training.•Behavioral observation.•Improved discrete trial teaching performance.

A procedure consisting of peer observation and evaluation termed behavioral observations was used to improve educational staff's correct use of discrete trial teaching procedures (DTT). All participants had been previously trained and proficient in using DTT procedures; however, during baseline, showed a low level of correct demonstration of DTT procedures (mean scores: 38.3%, 43.3%, and 35.0%). Participants were then taught use a checklist to observe and score a peer's performance during DTT sessions in a classroom setting. After conducting behavioral observations, staff increased their correct usage of DTT procedures to 85.1%, 88.3%, and 81.1% respectively. These data indicate that conducting behavioral observations can lead to large and rapid improvements in educational staff's correct use of DTT procedures with a large effect size (d = 4.19).
