Teaching

If we fail to plan, we plan to fail.

Learning-by-Engagement.

2026 - 1st Semester (2026.07.23): Comments Posted by Students About Ranjit's Teaching (Found in the University Website -- I am humbled and surprized too)

• 학생들에게 진심으로 가르쳐주고 싶어하시는 것 같아서 늘 감사합니다. (I am always grateful because it seems you genuinely want to teach the students.)

• 학생들이 이해하고 있는 지 수업 시간에 예시 문제를 풀어보라고 하셨고, 강의실을 둘러보면서 어려워하는 학생들에게 가서 다시 설명하며 이해하는데 도움을 주려고 하신 부분이 좋았다. (I appreciated that the instructor asked us to solve example problems during class to check our understanding, and that they walked around the room to provide further explanations and assistance to students who were struggling.)

• 학생과 수업에 대한 애정과 열정이 대단하시고, 강의를 너무 잘하신다. 화학에대한 기초도 거의 없는 상태에서 수강했음에도 화학에 흥미를 붙이게 해주셨다. (They possess tremendous affection and passion for their students and the subject, and they are an excellent lecturer. Even though I started the course with almost no foundational knowledge of chemistry, they helped me develop a genuine interest in the subject.)

• I love how professor Ranjit De cares about students and leads the class. The class was overall helpful in drawing interest in my studies.

• 교수님의 설명이 자세하고 이해 시켜주시려는 노력이 보이는 수업이다. 공지와 수업 시간이 적절하고 대형강의임에도 학생들이 타 대형강의에 비해 잘 집중하는 모습이 인상 깊었다. (The professor provides detailed explanations and clearly demonstrates a genuine effort to ensure students understand the material. The announcements and class timing are well-managed, and it was impressive to see students maintaining better focus compared to other large-scale lectures.)

• 진짜 다 떠먹여주시는 수업입니다. 모든 수업과 이론은 차근차근 알려주시지만 근데 또 과제는 혼자서 하도록 하십니다. 이런 교수님 또 어디서 찾을 수 있을까요. 저 교수님 없으시면 전과합니다. (This is a class where everything is truly spoon-fed to you. The professor explains every lesson and theory step-by-step, yet still ensures you complete the assignments on your own. Where else could you find a professor like this? If this professor weren't here, I’d switch majors.)
