The purpose of this study was to examine the effects of algebraic equation solving intervention for sixth graders with mathematics learning difficulties (MD). A total of 48 students with MD were randomly assigned to either the algebraic equation solving intervention, Mystery Math ( n = 24) or control condition ( n = 24). The multicomponent intervention was based on the principles of explicit instruction and focused on improving conceptual and procedural knowledge of algebraic equation solving using concrete manipulatives. Students in the intervention group received instruction in pairs, 30 min per session, 3 sessions per week for 5 weeks (i.e., 15 sessions). The results indicated that the main effect of intervention was significant for 2 proximal measures of mathematics vocabulary, and conceptual and procedural understanding of algebraic equation solving with large effect sizes. However, the main effect of intervention was not significant for distal measures of comprehensive pre-algebra skills and whole-number computations. The findings demonstrate that grade-level standards can be successfully taught to students with MD. Implications for practice are discussed.
This descriptive analysis of policy content examined local school district policies on physical restraint and seclusion in one Midwestern state that did not have state legislation on these topics to determine whether districts had policies and, if so, whether their content included recommended principles from the U.S. Department of Education. No previous research has addressed district policies. A maximum variation sample of 90 districts was examined to determine whether policies were in place, whether recommended principles were included, and whether policies varied based on student enrollment. Although almost all districts had policies, many of the federally recommended principles were not addressed across the sample and less than 10% of the district policies indicated that these procedures should only be used in the case of imminent danger of serious injury to self or others. District enrollment size did not affect policy, but the substance of the policy was determined by the districts’ policy source from advising attorneys.
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.
