一堂生动活泼的、具有教学艺术魅力的好课犹如一支婉转悠扬的乐曲,“起调”扣人心弦,“主旋律”引人入胜,“终曲”余音绕梁。其中,“起调”就是我们所说的课堂教学中的引入问题。引入新课是教学的重要和必要环节,俗话说:“良好的开始,就是成功的一半”。 A lively, good lesson with the charm of teaching art is like a melodious music melody, “tune ” exciting, “melody ” fascinating, “finale ” reverberations around. Among them, “tone ” is what we call the introduction of classroom teaching. The introduction of a new lesson is an important and necessary part of teaching. As the saying goes: “a good start is half of success.”
