Controversies in Learning English as an Additional Language in Early Schooling

As the English language spreads worldwide, debate has intensified over introducing it early in multilingual school systems. In the Arab world, this question is especially sensitive because Arabic is closely linked to cultural and religious identity, and early English policies may shift the language balance in primary education. This review synthesizes 31 peer-reviewed studies on childhood English learning and early English teaching practices, addressing key aspects of age of acquisition, bilingual outcomes, and language maintenance or identity. Using transparent search and selection reporting, we examined studies published between 2000 and 2025. Findings cluster around four themes: age of acquisition, mother-tongue maintenance and identity, teacher preparation and pedagogy, and social outcomes. The evidence from the review shows that earlier exposure can support pronunciation, fluency, and metalinguistic awareness, but the strength and direction of these gains depend primarily on program quality and bilingual model design. Additive approaches that maintain and value Arabic literacy while providing rich, high-quality English input are often associated with better learning outcomes than subtractive arrangements that reduce Arabic use. However, effects vary by context and implementation quality. Where Arabic is reduced without adequate support, learners may face risks such as weaker first-language development and heightened identity-related strain. However, these outcomes are not inevitable and are moderated by factors such as teacher preparation, instructional design, and school–home language support. We propose a balanced early-English design that builds progressive English proficiency while maintaining continuous Arabic-medium literacy, supported by targeted teacher professional development, family and community engagement, and continuous Arabic-medium literacy. The review concludes with policy and practice implications for curriculum designers, school leaders, and decision-makers, and calls for longitudinal, classroom-based research on identity trajectories and English-medium instruction in Arab primary education.
