A teacher's main role is to facilitate his students' learning of a subject and to ensure that every student's potential is stretched to the fullest. The following are the specific steps I take to promote learning: 1. Arouse my students' interest in the subject. 2. Explain basic concepts and principles clearly. 3. Provide suitable exercises or problems for my students to work on, and guide them, if necessary, to find solutions. 4. Emphasize correct learning attitudes. 5. Be approachable for consultation and willing to provide additional help.
