新课程理念要求教师成为学生学习的引路人,为学生扫清学习道路上的障碍.因此教师设计的教案应最大限度地便于学生理解和掌握所学的知识.从传授知识方面来讲这无可厚非,而且非常必要,但在素质教育的今天,从学生的一生发展来考虑,能力的培养则更为重要.在教学过程中教师有意设立“陷阱”让学生“掉”进去,再设法“走”出来,让他们在吃堑中长智,在摔倒后爬起,无疑对他们能力的培养、学习意志的磨炼都很有益处. The concept of the new curriculum requires that teachers become guides for students to learn and clear the obstacles for the students. Therefore, the teacher’s design of teaching plans should make it easier for students to understand and master the knowledge they have learned. This is understandable from the perspective of imparting knowledge. And it is very necessary, but in today’s quality education, from the students’ lifetime development, the cultivation of ability is even more important. In the teaching process, teachers intentionally set up a “trap” to allow students to “drop out” and try again. “Go” comes out, let them eat in the elixir of wisdom, climb after the fall, no doubt on their ability to cultivate, learning will exercise will be very beneficial.
