“勇于探究”是新课程改革的核心理念之一。它要求我们重新审视我们的课堂教学:从以教师为中心走向师生互动的“学习共同体”。本文结合笔者所在学校科学组的教学实践,从课前精心预设、课堂上捕捉有益信息以及利用课堂意外等三个方面,谈谈如何巧用勇于探究,使科学课堂教学更具丰富性、开放性、创造性与鲜活性。 “Courage to explore ” is one of the core concepts of the new curriculum reform. It requires us to re-examine our classroom teaching: from the teacher-centered to the interaction between teachers and students “learning community ”. Based on the teaching practice of the science group in the author's school, from the careful pre-class design, the classroom to capture useful information and the use of classroom accidents, talk about how to make the best use of courage to explore and make the science classroom more rich and open Sexuality, creativity and freshness.
