The current study sought to add to the literature on applying interdependent group-oriented contingency systems with randomized components to academic performance. This study expanded previous work, which has only examined effects on elementary classrooms and students with disabilities, by implementing a similar intervention within a general education, secondary classroom. Given the restricted time that teachers have to learn and implement interventions, while simultaneously carrying out all their additional responsibilities in the classroom, it is necessary for school psychologists to consider these limitations when recommending interventions. In previous work involving interdependent group-oriented contingencies, the delivery of reinforcement has been relatively immediate. While this is an ideal arrangement, it may be infeasible for middle and high school teachers to ensure reinforcement of academic performance occurs immediately within the class period. This study examined whether the delivery of reinforcement can be delayed within an interdependent group-oriented contingency system and still improve the academic performance of students in the classroom, which will allow the teacher more time for evaluating the quality of student work and, in turn, impact the acceptability of the intervention. One middle school, general education classroom served as the setting for this study. Academic performance data, including in-class work completion and accuracy rates, were collected class-wide and data on social behavior variables were gathered for 3 students exhibiting moderate to high levels of off-task behavior, based on teacher perception. An alternating treatments design was employed with two intervention conditions: one condition included immediate reinforcement and the other involved delivering reinforcement to students a day later. The interdependent group-oriented contingency intervention implemented included procedures for randomly selecting target behaviors, criteria, and reinforcers.

Students with specific learning disabilities (SLD) typically learn less history content than their peers without disabilities and show fewer learning gains. Even when they are provided with the same instructional strategies, many students with SLD struggle to grasp complex historical concepts and content area vocabulary. Many strategies involving technology have been used in the past to enhance learning for students with SLD in history classrooms. However, very few studies have explored the effectiveness of emerging mobile technology in K-12 history classrooms. This study investigated the effects of mobile devices (iPads) as an active student response (ASR) system on the acquisition of U.S. history content of middle school students with SLD. An alternating treatments single subject design was used to compare the effects of two interventions. There were two conditions and a series of pretest probesin this study. The conditions were: (a) direct instruction and studying from handwritten notes using the interactive notebook strategy and (b) direct instruction and studying using the Quizlet App on the iPad. There were three dependent variables in this study: (a) percent correct on tests, (b) rate of correct responses per minute, and (c) rate of errors per minute. A comparative analysis suggested that both interventions (studying from interactive notes and studying using Quizlet on the iPad) had varying degrees of effectiveness in increasing the learning gains of students with SLD. In most cases, both interventions were equally effective. During both interventions, all of the participants increased their percentage correct and increased their rate of correct responses. Most of the participants decreased their rate of errors. The results of this study suggest that teachers of students with SLD should consider a post lesson review in the form of mobile devices as an ASR system or studying from handwritten notes paired with existing evidence-based practices to facilitate students’ knowledge in U.S. history. Future research should focus on the use of other interactive applications on various mobile operating platforms, on other social studies subjects, and should explore various testing formats such as oral question-answer and multiple choice.
