在初中阶段,数学课堂上应以“问题”为教学的核心。因为数学的研究和教学都是从一个问题开始的。课堂教学中的“主问题”是指能对学生的学习起到“牵一发而动全身”的问题,能使学生在整体参与性上引发思考、讨论、理解、探究、创新的重要提问或问题,它在课堂教学过程中能起主导、支撑作用。所以,在实际的数学教学中,教师要尝试用主问题作为引领,就此,将结合教学经验谈一谈心得体会。
In junior high school, mathematics classroom should be “problem ” as the core of teaching. Because mathematics research and teaching are starting from a problem. The “main problem” in classroom teaching refers to the problem that can play a role in “learning from one place to another” in the study of students, which can lead students to think, discuss, understand, explore and innovate on the whole participation Important question or problem, it can play a leading and supportive role in the classroom teaching. Therefore, in the actual teaching of mathematics, teachers should try to use the main problem as a guide, in this connection, will talk about experiences and experiences experience.
