Teaching Pattern

Methodology Lectures: key concepts of the subjects will be provided. Students are expected to read and understand the contents from textbook and reference books after classes. To enhance their learning and knowledge, supplementary materials will be taken from daily examples and journal articles to illustrate the application and most recent developments of electrochemistry. Tutorials: Students are encouraged to discuss and present their solutions to problem sets to gauge their leaning and performance. These problem sets provide them opportunities to apply the knowledge gained from the lecture. They also help the students consolidate and familiarize with what they have learned. Furthermore, students can develop a deeper understanding of the subject through group discussion and self-study
