导学案早在新课程改革前,就被广大教师普遍运用,但由于主观认识、教材编写等一些客观因素的制约,在实施中受到了一定的限制,存在着不少问题。本文在前人研究的基础上,从现在教育改革方向着眼,结合自己的教学谈谈高中化学教学中导学案的作用及设计。 As early as before the reform of the new curriculum, the guide case was widely used by a large number of teachers. However, due to the subjective understanding and the compilation of some teaching materials, some objective factors restricted the implementation of the curriculum and caused a lot of problems. On the basis of the previous studies, from the current direction of education reform, this article, with its own teaching, talks about the role and design of the guiding lesson in high school chemistry teaching.
