You know your discipline. Now teach it in English with confidence. This practical handbook gives university lecturers the precise classroom language, technical grammar, and discipline-specific vocabulary they need immediately. Designed for teachers of engineering, physics, chemistry, metallurgy, mining, and maritime studies, it includes French translations for key terms to support bilingual contexts. No theory. Just ready-to-use expressions, lesson plans, rubrics, and templates for explaining processes, describing graphs, leading labs, giving feedback, and assessing students. English as a working tool. For teachers. By teachers.
