Ph.D. and M.Sc.
My scope is to encourage students to apply knowledge they have to critically analyze situations and solve problems. I wish my students to be critical of what they hear, form their own opinions and be equipped to defend their opinions in an intelligent and articulate manner. My responsibility is to teach the student and the students’ responsibility is to learn; my job, as teacher is to make their job (learning) productive. As educator, I plan to use innovative methods, respond enthusiastically to questions, and encourage our students to enthusiastically seek knowledge. I seek to understand the learning capabilities and goals of students in my classes; departing from conventional teaching methods to ensure the entire class develops the requisite skills and grasps the information presented to be successful in the future.
