Many teachers believe that the responsibilities for learning lie with the student. {#blank#}1{#/blank#} a long reading assignment is given, instructors expect students to be familiar with {#blank#}2{#/blank#} (inform) in the reading even if they do not discuss it in class or take an examination.

Sometimes homework is returned {#blank#}3{#/blank#} brief written comments but without a grade. Even if a grade is not given, the student is {#blank#}4{#/blank#} (responsibility) for learning the material assigned. When research {#blank#}5{#/blank#} (assign), the professor expects the student to take it actively and to complete it with minimum guidance. It is the student's responsibility to find books, magazines, and articles in the library. Professors do not have the time to explain {#blank#}6{#/blank#} a university library works; they expect students, {#blank#}7{#/blank#} (especial) graduate students, to be able to exhaust the reference origins in the library. Professors will help students who need it, but prefer that their students should not be too dependent on them. In the United States, professors have many other duties {#blank#}8{#/blank#} teaching, such as administrative or research work. Therefore, the time {#blank#}9{#/blank#} a professor can spend with a student outside of class {#blank#}10{#/blank#} (limit). If a student has problems with classroom work, the student should either approach a professor during office hours or make an appointment.
