This longitudinal study investigated bidirectional associations between pupils' social competence and their interpersonal relationships and classroom climate in segregated special education schools for pupils with emotional and behavioral disorders in the Netherlands. Participants were in Grade 4 and 5 in School Year 1 (N = 441) and Grade 5 and 6…

The "Next Generation Science Standards" framework outlines scientific and engineering practices as a key element of student development. Educators are just beginning to discover effective and meaningful ways to teach science content to students with intellectual disability; however, the literature on teaching science practices is still…

Instruction targeting the underlying math problem structure is identified as an evidence-based practice for students with a specific learning disability (SLD). Furthermore, schema-based instruction is identified as a potentially evidence-based practice for students with a SLD. This study extended prior work by (a) using a teacher as the…

The present study examined the role of language capacities in explaining differences in social information processing (SIP) among three school-age groups: high-functioning children with autism spectrum disorder (ASD, IQ > 75), children with specific learning disorder (SLD), and children with typical development (TD). Participants were 96 boys…

Our purpose was to examine different approaches to modeling the time-varying nature of exceptionality classification. Using longitudinal data from one state's mathematics achievement test for 28,829 students in Grades 3 to 8, we describe the reclassification rate within special education and between general and special education, and compare four…

The present study investigates the relationship between childhood placement in special education and adult well-being among 1,377 low-income, minority children participating in the Chicago Longitudinal Study. Roughly 16% of the sample received special education services in Grades 1 to 8. After accounting for sociodemographic factors and early…
