My teaching philosophy is based on the foundation of my educational experience, which has given me important lessons that I would like to apply as an educator. First, one important responsibility of an instructor is to provide students with the knowledge necessary for their future studies and career. Well-organized lecture notes with carefully selected sample questions may arouse the students’ interests and curiosity, and motivate them toward further studies. To explain complex concepts or solve challenging problems, I strive to use intuitive examples related to real world issues to illustrate the basic laws under them. I always encourage students to focus on fundamental principles and deductive reasoning instead of simply memorizing the results. I also assign homework and evaluate students’ performance regularly, which reflects whether or not the presented materials are well absorbed. Meanwhile, with the rapid advances of wireless communication and networking technologies, my lectures are updated to expose students to the state-of-the-art technologies and the future trends so that students can be well prepared for their future career. Second, the interaction commitments between students and the instructor are very important to make teaching and learning an interesting, rich and rewarding experience for both parties. I like to stimulate the students through my enthusiasm for the course material since I believe enthusiasm is contagious in the class. I encourage students to actively participate in the teaching and learning process. By raising questions and arguments on a subject, I try to guide students on the right way to solve problems through in-class discussions and debates. To further facilitate students learning, I like to provide opportunities for reflection and feedback from students via after-class and office hour discussions, peer-to-peer feedback on assignments and learning activities, formal and informal evaluations, etc. Students responses and inputs are very helpful for improving my teaching skills. Third, but not less important, an educator should inspire students to challenge existing practices and encourage them for scientific inquiry and critical thinking. I would also like to recommend that students explore further by extra reading and searching for alternatives or better approaches. Only through the questioning and deep thinking, students can be empowered with self-confidence that the knowledge has been well gained and can be applied for solving practical problems. The ultimate goal of successful teaching is to enable the students to master and to skillfully deploy the knowledge exposed to them.
