教学既包含教师的教,又包含学生的学,是教与学相互作用的一种双边活动。研究教学不但要研究教而且要研究学。但教学问题说到底还是学生的学习问 Teaching includes both teacher’s teaching and student’s learning. It is a bilateral activity of interaction between teaching and learning. Research teaching should not only study teaching but also study. But in the final analysis, the question of teaching is still a matter of student learning.
