Ask your teacher to answer a question by raising your hand during or after a lesson, or wait for her to provide a question-and-answer time. You can also email her your question or request an appointment to meet her. Use the correct form of address, and be polite.
Improve your performance by asking your teacher questions when you need help to understand topics or instructions. Allow the teacher adequate time to give you a comprehensive and useful answer. If you are absent for a class, ask for missed work. In an email, number your questions if you ask more than one. Use an active approach that shows your effort in trying to understand the problem.
Formulating and asking well-considered and open-ended questions in order of priority engages students in the learning process, makes them more responsible and enriches their quality of work.
