An alternating treatments design was used to evaluate and compare the effects of two interdependent group contingencies on the academic performance, on-task behavior, and disruptive behavior of eighth-grade students in a social studies class. All students were enrolled in a self-contained alternative school for students with behavior problems. Delivering rewards contingent upon participants’ average percent correct enhanced on-task behavior and percent correct on independent seatwork assignments; however, delivering rewards contingent upon participants’ on-task behavior yielded more consistent and larger increases in percent correct and on-task behavior. Neither group contingency resulted in consistent or meaningful changes in disruptive behavior. Theoretical and applied implications related to direct and indirect effects of interdependent group rewards are discussed along with directions for future research.
Students with intellectual disability often have difficulty reading commonly used words. Researchers have found altering printed text from fluent, easy-to-read font, to disfluent, difficult-to-read font can enhance comprehension and recall. An adapted alternating treatments design was used to evaluate and compare sight-word acquisition and maintenance in three postsecondary students with intellectual disability when flashcards were presented in fluent (i.e., 14-point Arial) and disfluent (i.e., 14-point Juice ITC reduced to 70% transparency) fonts. Results showed all three students acquired and maintained both fluent and disfluent words, with two of the three students learning more fluent words. These findings suggest altering fonts to make them difficult to read can hinder, rather than enhance, word learning in students with intellectual disability. Directions for future research are provided with a focus on the need for aptitude-treatment interaction studies.
Elementary school multicultural reading curricula include characters with diverse proper names, which are often unfamiliar and differ phonetically from students’ native language. These names could impact reading outcomes by increasing students’ cognitive load and/or creating cognitive disfluency. In Study 1, students in grades 1 through 2 read a standard passage including common names and a matched passage including unfamiliar names of Russian origin. A paired samples t test indicated unfamiliar diverse names in grade-level passages significantly reduced students’ reading comprehension. Study 2 was designed to determine if preteaching diverse names would mitigate their adverse effects on reading comprehension. Results indicated second-grade students who received preteaching comprehended significantly more of the passage than those who did not receive preteaching. Discussion focuses on the need for research clarifying the relationship between multicultural learning materials and academic outcomes and validating efficient methods for familiarizing students with difficult, phonetically unfamiliar words.
Higher education continues to place an emphasis on service-learning, specifically within business and management sciences (Kenworthy-U' Ren & Peterson, 2005). A local academic business organization at a small institution chose to embark on a service-learning endeavor. The purpose of this study was for business majors, active in Phi Beta Lambda (PBL), and their advisors/professors to further investigate microlending and other business-related concepts through the use of service learning. Service was provided to the campus community, area high school Future Business Leaders of America (FBLA) students, and to the borrowers of their Kiva loans. The research, qualitative in nature, employed case study methodology. Themes emerged in academic, personal, and civic dimensions as a result of analysis of student responses to guided questionnaires.
Working with a post-secondary student with intellectual disability, an adapted alternating treatments design was used to compare sight-word acquisition across three computer-delivered learning trial interventions: one with fixed 5-s response intervals, another with fixed 1-s response intervals, and a third with self-determined intervals. Visual analysis of session-series graphs suggest that all three interventions increased sight-word acquisition with the 5-s and self-determined interventions causing more steady and consistent learning per session than the 1-s intervention. Analysis of the time-series graph suggests that the self-determined intervention caused superior learning rates to the other interventions. From an applied perspective, the self-determined intervention is the most appropriate remedial procedure for this student because it resulted in the most rapid learning. Discussion focuses on the value of making relative-effectiveness decisions based on measures of learning as a function of time spent learning (learning speed) versus measures of learning as a function of sessions or trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
