After working as a TA for the last 9 semesters, I understand that the main challenge is understanding the student problems clearly from their point of view. I used my previous experience to solve such issues. In such cases, I tried to listen to student problems, what they tried to solve their problems, and new ideas to solve the problems. Then I try to reply back. Another challenge I have faced in CS-1320 is that there are students from different educational backgrounds. In such cases, I tried to help them to understand programming and develop ideas from their perspective. It will help them to solve their own background problems using CS techniques. In CS-3331, some students misunderstand the ideas in developing UML Class diagrams, state machines, object-oriented design concepts, and so on. The challenge is to teach those concepts in a simple way so that students can understand and implement that. Still, I am trying my best to overcome those challenges by developing myself professionally in the upcoming semesters.
