谈谈初中数学探究能力培养

Talk about junior high school mathematics inquiry ability training

树立探究意识,积极正确引导。探究并不是盲目探究,而是有目的有计划性的探究.在教学实践中,培养学生的探究能力首先要引导学生树立正确的探究意识,为学生设立一个问题情境,让学生从中分析探究,寻找探究对象并深入思考提出解决方案,从而达到提高锻炼学生探究能力的目的.例如在人教版初中数学教材中,有关于"圆"的教学内容,主要是通过讲解点与圆、圆与直线之间的位置关系,从而进一步引入关于圆与多边形、如何利用圆计算弧长和扇形面积、圆周率等概念.课本内容无形和教师有形的引导,潜移默化间激发学生的自主探究能力.在初中数学中探究能力十分重要,运用得也非常普遍.教师要深刻认识到这一点,对于基础知识细讲深讲,保证学生能够充分理解,对探究知识则粗讲,以学生探究为主,教师只起引导作用.

to establish a sense of inquiry, and to guide actively and correctly.Inquiry is not a blind inquiry, but a purposeful exploration. In the practice of teaching, cultivate students' exploring ability to guide students to establish correct first explore consciousness, for the students to set up a problem situation, lets the student analysis to explore, looking for the object and puts forward solutions to deep thinking, so as to achieve the purpose of the exercise to improve students' ability to explore. In one version of junior middle school mathematics teaching material, for example, about the teaching content of "circle", mainly through the interpretation of the point and the location of the relationship between circular, circular and linear, thus further introduction about round and polygonal, how to use the circular arc length calculation and the fan area, PI and other concepts. The textbook content is invisible and the teacher's physical guidance, the subtle influence to stimulate students' self-exploration ability. The ability to explore in middle school mathematics is very important and it is very popular. Teachers should be deeply aware of this, and speak deeply about the basic knowledge, so as to ensure that students can fully understand it, and in the case of inquiry knowledge, they will only play a guiding role.
