Does special education predict students’ math and language skills?     

Ratib Lekhal 《欧洲特需教育杂志》2018,33(4):525-540

A large number of children are today receiving special education in Norway. The high cost to society and possible long-term consequences for the students make it important to understand the interrelationship of the causes and effects related to receiving special education services. Unfortunately, at present there are only few rigorous studies of the effects of receiving special education services. This study examined the interrelationship between receiving special education services and students’ math and language skills in upper secondary school in Norway. Data from 2756 students in the large population-based special education study (SPEED) was used that included information from questionnaires on students’ development, learning environment and family background. Results showed that students receiving special education services had slightly lower scores on their language test but similar scores on their math test compared to the group of students not receiving special education services, when conservative methodological approaches were used to control for possible covariate bias.  相似文献   

Little Evidence That Time in Child Care Causes Externalizing Problems During Early Childhood in Norway

Associations between maternal reports of hours in child care and children's externalizing problems at 18 and 36 months of age were examined in a population‐based Norwegian sample (n = 75,271). Within a sociopolitical context of homogenously high‐quality child care, there was little evidence that high quantity of care causes externalizing problems. Using conventional approaches to handling selection bias and listwise deletion for substantial attrition in this sample, more hours in care predicted higher problem levels, yet with small effect sizes. The finding, however, was not robust to using multiple imputation for missing values. Moreover, when sibling and individual fixed‐effects models for handling selection bias were used, no relation between hours and problems was evident.  相似文献
