EXPERIENCE IN USING DIVERSE AND EFFECTIVE TEACHING/LEARNING METHODS
Student-centered learning puts students' interests first, acknowledging student voice as
central to the learning experience. In a student-centered learning space, students choose
what they will learn, how they will learn, and how they will assess their own learning.
So, I practice with Student-centered learning methods instead of teacher-centered learning.
My teaching methods include
(1) Active learning: In which students solve problems, answer questions, formulate
questions of their own, discuss, explain, debate, or brainstorm during class;
(2) Cooperative learning: In which students work in teams on problems and projects
under conditions that assure both positive interdependence and individual accountability;
(3) Inductive teaching and learning: In which students are first presented with
challenges (questions or problems) and learn the course material in the context of
addressing the challenges. Inductive methods include inquiry-based learning, case-based
instruction, problem-based learning, project-based learning, discovery learning, and just-in-
time teaching.
AREAS OF EXPERTISE (Area).

Control, Vendor-Buyer Coordination, Development of the Heuristic Technique for solving
NP-hard problems appeared in the field of OR, etc), Combinatorial Optimization
