As a teacher assistant, I am always thinking about preparing my students with up-to-dated teaching materials and examples; however, I can see many TAs in my department who teach the content they used to teach in the past semesters and now it is obvious that because the students have access to the previous year's pamphlets and handouts, they are not encouraged to attend these TAs classes. Even some of these students just copy and paste the problems and assignments from the past homeworks.
As a teacher assistant, how can I avoid being stuck in repetitive teaching?
However, changing the problems each semester seems really a hard work and is almost impossible because the TA has to revise more than a hundred question or even find such quantity of new problems.
What are the techniques you use to keep your teaching material up-to-dated and alluring to the interested student; also to avoid lazy student to copy the paste semester materials?
As asked in one of the comments,
The courses I do teaching assistantship is engineering mathematics for masters students consisting solution of partial differential equations and also ordinary differential equations for bachelors students of engineering or one or two other subjects related to my major; (each semester I may have only one of these classes, I don't take simultaneous teaching assistantship classes).
I have regular classes each week for instance having two hours a week teaching assistant class.
I usually prepare some problems and after a brief review on the methods, formulas and concept; I solve those problems for students. I usually photocopy my problems for my students. Also, at the end of each topic, I assign them some problems to solve and ask their questions if they have any. Also, I give them two exams, one at the middle of the term and one at the end of each term.
