Content and Language Integrated Learning (CLIL) integrates subject knowledge with foreign-language proficiency to build both linguistic and conceptual competence. Guided by NEP 2020’s emphasis on bilingual skills, this quasi-experimental single-group study examines CLIL’s impact in science teaching for 20 pre-service teachers. Results show improved subject-related vocabulary, deeper conceptual understanding via bilingual instruction, heightened motivation, stronger problem-solving, better cognitive development, and increased language proficiency, while noting needs for teacher readiness and assessment.

Background: Content and Language Integrated Learning (CLIL) is a teaching methodology that integrates learning subject content with acquisition of proficiency in a foreign language (skills), developing both linguistic and conceptual competence. The approach aligns with the recommendations of the National Education Policy (NEP) 2020, which emphasizes the development of bilingual skills and cognitive abilities.
Purpose: The present study explores the efficacy of CLIL in science teaching, with particular emphasis on its influence on content knowledge, cognitive development, and bilingual language acquisition among pre-service teachers.
Method: A quasi-experimental pre- and post-test single-group design was adopted. The study was conducted on 20 pre-service teachers enrolled in the B.Ed. program at Chitkara University. A mixed-method approach was employed, incorporating both quantitative and qualitative data collection and analysis.
Results: Findings indicated that CLIL enhances vocabulary related to subject matter, deepens conceptual understanding through bilingual instruction, and increases student motivation and interest. It also positively impacts problem-solving skills and overall cognitive development, alongside improving language proficiency.
Conclusions: The study concludes that CLIL holds significant potential to enrich science education by fostering both cognitive and linguistic growth. However, challenges such as teacher preparedness and effective assessment strategies remain. The research highlights the need for further investigation into long-term outcomes and teacher training to maximize the educational benefits ofCLIL. | | | 1. Introduction
1.1. CLIL: Meaning and Definition
According to Coyle et al. (2010), Content and Language Integrated Learning (CLIL) is defined as an efficient pedagogy that integrates the content of the subject with the learning of language and has greatly enriched the art of teaching science through the accumulation of conceptual and linguistic skills in the 4Cs framework: content, communication, cognition, and culture.
Content and Language Integrated Learning (CLIL) is a teaching methodology in which foreign language instruction is used to teach subjects, with the goals of both improved language and subject matter proficiency (Marsh, 1994) . Academic content, for | | example, science or history, is learned by students in a CLIL environment as they enhance their proficiency in the target language, for example, English. This method is rooted in cognitive and language acquisition theories, supporting critical thinking and active learning. CLIL has been extensively used in multilingual and bilingual education contexts, providing advantages like enhanced language proficiency, higher cognitive flexibility, and more effective subject matter learning (Aravind, 2018) . Though it has its drawbacks, such as requiring competent teachers well-versed in the topic as well asthe target language and the challenge of measuring the achievements of the students in both aspects, there is research done on CLIL. It discusses the effectiveness of CLIL, establishing best practice, results, and topics | ©Author(s) 2025. This article
