For example, in unit 7, the further discussion section tackles some open questions that can be made between one of two groups of students. Instead, the activity is not designed for this purpose. The pair and group activities are not much used in the curriculum. Most of the tasks are required to be performed by the student himself. The pair and group activities need to be maximized in order to enhance interaction between the students and the teachers and between the students and their peers. (P. 92).
