Andrew T. Thren co-authored a book titled “Classroom Questions: Understanding Teacher Questions in Junior High School English” with his colleague, Lesly Narwasti Ndun. The book Classroom Questions analyzes how teacher questioning in junior high English classes fosters comprehension and participation. It explores the types and purposes of questions, how students respond, and shows that questioning helps check understanding, elicit language, and engage learners. This book can equip teachers to understand their own teaching interactions and improve classroom communication.
