小题2:Participation in the classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student's oral participation. Although there are formal lectures during which the student has a passive role (i.e., listening and taking notes), many courses are organized around classroom discussions, student questions, and informal lectures. 小题3:Many teachers believe that the responsibility for learning lies with the student. (Courses are not designed merely for students to pass exams.) The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades. 小题4:Ideally, the teacher-student relationship at universities is characterized by trust. Thus, cheating on tests, Plagiarizing (抄袭) in written work, presenting other's ideas as original, and turning in homework completed by someone else are all prohibited (禁止). 小题5:Relationships between students in the classroom can be cooperative or competitive. International students should not hesitate to ask for help if it is needed. in classes where such a grading curve is used, students may be reluctant to share lecture notes or information for fear that their own grades will suffer. |
