Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

Reflects on the achievement in math and science of Australian students in an immersion French program. The immersion math students outperformed mainstream students at a level not significantly different, and by the end of the first year, the science students performed as well as their mainstream counterparts, indicating that immersion students…

A study in an early French partial immersion program in a Melbourne (Australia) elementary school investigated participating children's performance in mathematics in English (their first language) and French. Mathematics testing in both languages has been undertaken regularly as part of a long-term evaluation of the program. In the first year of…

A study of the differences in achievement among Ottawa's grade 9 and 10 students taught in English and French in three subject areas (mathematics, geography, and history) in which suitable comparative measures were available had as subjects the students in 73 classes. The students in French-language classes were administered the test twice, once…
