We evaluated the effectiveness, generality, and social validity of a modified version of a competencybased self-control package developed by Stevenson and Fantuzzo (1984). Three underachieving fifth-grade students were trained to use this intervention to increase their arithmetic proficiency.Results indicated that the intervention produced improved arithmetic performance. Moreover, all possible classes of generalization were evidenced for the participants. Social (1984) and to extend them by assessing the social validity of both treatment and generalization effects in the school setting. Additionally, the original set of training procedures was modified to enhance generalization furher.
METHOD Subjects and SettingsSix black elementary school students from three regular fifth-grade classes participated. Two children were selected from each class based on the following criteria: (a) history of poor arithmetic performance, (b) one grade level behind in arithmetic skills, (c) low socioeconomic status, and (d) children who lived within 3 km of each other. One of the two students was randomly selected to serve as the treated student; the other served as the control.The research was conducted in three standard elementary school classrooms and in the homes of the treated students. School data were collected 269 1986, 199 269-276 NUMBER 3 (FALL 1986)
