In this study, we investigated the relationships between three pivotal factors that influence student performance, including opportunity-to-learn (OTL) factors, which included proximal indicators that represent science-specific learning opportunities, student motivation (propensity factor), and crucial student and teacher antecedent factors by…

Background: The acquired skill set prior to school entry has emerged as an important issue in research and policy internationally. Much evidence exists advocating the importance of early numeracy and literacy skills in later academic achievement and economic outcomes of students. Aim: The goal of this study was to determine the association between…

This study examined the individual, class, and school level variability of the students' science achievement. It was hypothesized that there are school or teacher effects which contribute toward explaining achievement differences, besides the student level differences. Owing to the nested structure of the data in Trends in International…

This paper reports on secondary analysis of TIMSS 2003 data with the aim of explaining the difference in science achievement of Korean and South African learners. The question asked by this research, i.e. which factors at various educational levels influence science achievement in Korea and South Africa respectively, is addressed from the…
