Language of instruction in schools in low- and middle-income countries: A systematic review.

Based on the theory of change, we gather, organize, and synthesize the evidence on the impact of three language of instruction (LOI) choices (teaching in mother tongue [MT] with later transition, teaching in a non-MT language, or teaching in two or more languages at one time) on literacy and biliteracy outcomes. We focus on quantitative and qualitative studies of LOI interventions in low- and middle-income countries (LMICs) and consider languages that are commonly spoken in the developing world. As such, we include studies that examine transfers from local languages to English, but not those evaluating transfers from local languages to languages that are less spoken in LMICs (e.

PROTOCOL: Language of instruction in schools in low- and middle-income countries: A systematic review.

To address the evidence gap in making effective language of instruction (LOI) decisions, we propose a systematic review of the role of LOI choices in education programs and policies on literacy outcomes in multilingual educational contexts in low- and middle-income countries (LMICs). Grounded in a multidisciplinary theory of change (ToC) describing what factors link LOI choices and literacy outcomes, we will gather, organize, and synthesize the evidence on the specific role of the three LOI choices described in the ToC (teaching in mother tongue [MT] with later transition, teaching in a non-MT language, or teaching in two or more languages at one time) and its impact on literacy and biliteracy outcomes. We will focus our systematic review and meta-analysis only on quantitative and qualitative intervention studies from LMICs as these have the highest relevance for decision making in multilingual LMIC contexts.

Reading Research and Practice: Indian Perspective.

The authors outline the basic structure of akshara, the basic unit of writing in Indic writing systems used widely in South and Southeast Asia; present preliminary studies relating to reading, assessment, and instruction of akshara; and outline recommendations for future studies.

Investigating the Asymmetrical Roles of Syllabic and Phonemic Awareness in Akshara Processing.

In this study, we examine the relative contributions of syllabic awareness, phonemic awareness, and oral vocabulary knowledge in early akshara reading ability from Grades 1 through 5. The performance of 488 students in two states of South India, Karnataka (Kannada language) and Andhra Pradesh (Telugu language), was measured. Results from a commonality analysis indicate that there was an increasing independent contribution of syllabic awareness to Kannada and Telugu decoding through the five grades, but the unique contribution of phonemic awareness steadily declined through the five grades, as it became subsumed within syllabic awareness.
