Dr. Miriam Chitiga, chair of the Department of Educational Leadership and School Administration “presents a mixed methods study conducted in a bilingual mathematics classroom in Zimbabwe in this text. She reveals the semantic pedagogical functions and linguistic forms of code-switching during STEM instruction. Ultimately, the text identifies implications for teacher education, language policy, and educational leadership more broadly. This text will benefit researchers, academics, and educators with an interest in bilingualism, applied linguistics, and secondary education more broadly. Those specifically interested in multicultural education, sociolinguistics and educational policy will also benefit from this book.” It is available at www.routledge.com.
