Effects of Curricular and Materials Modifications on Academic Performance and Task Engagement of Three Students with Emotional or Behavioral Disorders
Effects of two curricular and materials modifications on the on-task behavior and correct academic responding of three elementary-aged students identified with emotional or behavioral disorders (E/BD) were evaluated in two separate studies. In the first study, an ABA design revealed little difference in the students’ correct responding or on-task behavior when a function (writing a letter) was provided for written assignments. When a model for correct responding was added to the conditions, correct responding and on-task behavior increased for all students in both the functional and nonfunctional activities. In the second study, a multiple-baseline-across-students revealed only limited positive effects for on-task behavior when arithmetic assignments were shortened; effects were enhanced for two of the students when a model for correct responding was added to the shortened assignment modification. Results are discussed in terms of continuing research needed in the area of curricular and materials modifications for students with E/BD.
