Bilingualism and academic achievement.

Area of Science:

• Child development
• Educational psychology
• Linguistic studies

Background:

• Bilingualism's impact on academic performance is a key area of research.
• Understanding developmental trajectories in early school years is crucial.
• The influence of the school environment on academic outcomes needs further exploration.

Purpose of the Study:

• To investigate the role of bilingualism in academic development.
• To analyze the impact of the school environment on bilingual children's academic trajectories.
• To compare the academic performance of different bilingual groups with monolingual peers.

Main Methods:

• Utilized data from the Early Childhood Longitudinal Study, Kindergarten Cohort (N = 16,380).
• Employed growth-curve modeling to track academic trajectories.
• Examined differences in reading and math scores across various linguistic groups.

Main Results:

• Mixed Bilingual children closed the math gap with White English Monolingual peers by fifth grade.
• Non-English-Dominant Bilinguals and non-English Monolinguals showed persistent score gaps in reading and math.
• School-level factors accounted for one-third of the reduction in academic performance differences.

Conclusions:

• Bilingualism, particularly the 'Mixed Bilingual' category, shows potential for academic catch-up.
• Persistent achievement gaps exist for non-English-dominant and non-English monolingual students.
• School environments play a significant role in mitigating academic disparities.
