This study examined the impact of linguistic and cultural enhancements to evidence-based mathematics instruction within a multitiered support system for English learners. The study employed a single subject changing criterion design for four fourth-grade students who were English learners with or at risk of a learning disability diagnosis in mathematics. Dual dependent variables were mathematics vocabulary acquisition and application in story problems. Student performance on identifying the correct mathematics vocabulary words when given the definition was measured across baseline and four phases of intervention. Students were also assessed on their ability to complete story problems that contained the target vocabulary. At each phase of the intervention, students showed an increase in performance on both vocabulary words correctly identified and story problems correctly completed. Implications for practice and future directions for research are discussed.
In this investigation, the authors examine the relationship between individual skills (i.e., career locus of control [LOC], social skills [SOC], and social problem–solving skills [SPSS]) and the school- and perceived career–related adjustment of 211 students with disabilities. Data pertaining to individual skills were gathered from student reports, and data pertaining to adjustment were gathered from student and teacher perceptions. Results of hierarchical regression analyses indicated that together LOC, SOC, and SPSS accounted for a significant amount of variance in student- and teacher-rated school- and career-related adjustment after controlling for disability type. Evaluation of individual predictors indicated that the strength of these associations varied according to data source and the specific predictor under study.
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.
