Referring to the current curriculum applied in English Education Department at one of universities in Indonesia, third semester students start to get theory-based subjects such as Principles of Teaching and Learning and Language Learning and Acquisition. Enrolling the subjects, students are demanded to read theoretical books and journal articles which the topics might not be familiar for them. They are also required discussing current issues related to the topics that they do not meet in the previous semesters. In reading the books and discussing some issues, they meet new terms and knowledge. The challenges are about how to comprehend the new knowledge while they are still struggling with the English language. Consequently, teachers of theoretical subjects should help students do the challenges and facilitate their comprehension on the materials discussed through classroom activities. Technically, the aforementioned subjects were offered to third semester students who were divided into four classes (class A – class D) and four teachers were involved to teach the subjects. In a result, there must be various classroom activities conducted. It would be interesting to know what activities were implemented to facilitate students’ comprehension on the subjects and what students’ responses are toward those activities. To accommodate that aim, a qualitative research is done. Then, students from different classes are interviewed to get the data. The findings of this research will reveal classroom activities done by the teachers to teach theory based-subjects and students’ responses toward those activities.
