“…In responding to behavior, Simonsen et al (2015) emphasized the importance of consistency, specificity, timeliness, and consideration of the function of the behavior. Although it is widely recognized that identification and treatment of the function of an individual’s behavior is an effective intervention practice (Gresham, Watson, & Skinner, 2001), it should be noted that there is a dearth of research on function-based assessment and treatment procedures targeting a class unit. To date, only two studies have investigated descriptive assessment methods to identify functional variables to design treatment for a class (McKerchar & Thompson, 2004; Vanderheyden, Witt, & Gatti, 2001), with only one testing the effectiveness of the treatment following the assessment process.…”
