The goal of the study was to provide empirical findings on the effects of different types of parents’ school involvement (PSI) on their children's mathematics performance. For PSI, we explored parent participation in parent–teacher conferences, voluntary parental involvement in school activities, parent informal contact with school or teachers, and parental phone contact with school or teachers. In addition, we paid focused attention to families of linguistic and racial minority groups who may have different dynamics of PSI for children's schooling and academic achievement. We conducted comprehensive descriptive statistics and multilevel longitudinal modelling using a nationally representative database, the Early Childhood Longitudinal Study (ECLS-K), to establish study conclusions with high validity and generalizability. The results showed that four different types of PSI had differential effects for different linguistic and racial groups. The study findings have practical suggestions and implications fo...

This paper examines the long-term effect of enrollment in center- or school-based care programs on the academic performance of language minority students in the USA. The study applies a longitudinal multilevel analysis to a nationally representative database, the Early Childhood Longitudinal Study (ECLS-K). Of particular interest are the differential effects of the programs on the reading performance of language minority students compared with that of native English-speaking students. Language minority students are further divided into 2 groups according to Limited English Proficiency (LEP) status at kindergarten. Results indicate that kindergarten LEP students who regularly attended center-based programs from preschool through the 5th grade demonstrated a significantly higher reading score than those who did not. The study suggests an important potential benefit of arrangement of afterschool care programs for language minority students in the USA and other countries.

The study explored the relationship of self-concept and locus of control to science engagement and science achievement. Furthermore, the relationship of self variables with science engagement and science achievement was studied across ethnicity, gender, and socioeconomic status (SES). The data were accessed from the 3 waves of the National Education Longitudinal Study: 88 (NELS:88) to estimate both cross-sectional and multilevel longitudinal models. It was hypothesized that self-concept and locus of control would have a positive effect on science engagement and science achievement and that science engagement would affect science achievement positively. The results supported the theoretical formulations of the conceptual model and showed significant effects of self-concept and locus of control constructs on science engagement and science Item Response Theory (IRT) scores. Furthermore, science engagement showed a positive but small effect on science achievement, especially the time spent on science homework...
