Abstract: In view of the current hot topics related to undergraduate teaching, this paper draws the following conclusions based on historical investigation and realistic examination. Although college teaching and learning need theoretical research, it depends more on faculty's independent and intellectual practical exploration, individual experience accumulation. Learner-centered instruction is an initiative stimulated by the situation, rather than a teaching mode or paradigm that breaks with the tradition. Relevant evidence shows that the exploration of effective teaching is still inseparable from the teacher's leading and organization, without which the routine instruction will move toward disorder and inefficiency. Learner-centered instruction tends to be limited by certain objective resource constraints, and thus needs something like community's institutional environment and cultural support.

Key words: undergraduate instruction, scholarship of teaching and learning, learner-centered instruction, effective teaching
