“发现法”是近年来教学改革中提倡的一种启发式教学法.正如美国的布鲁纳所说,发现“包括用自己的头脑亲自获得知识的一切方法”.但是,“发现”这个词往往被人们所误解,有人认为小学生连老师讲的知识都掌握不了,却让他们去发现什么概念、法则、定律、公式,未免过于苛刻了.事实上,我们所说的“发现”,并不是要求或希冀学生马上去发明一件什么东西,而是鼓励学生利用教师或教科书提供的材料,通过独立思考,在已有知识的基础上,发现应得的结论.只有在学生遇到无法逾越的障碍的时候,教师才给予必要的帮助和指导.在小学数学教学中,恰当地运用“发现法”,能够促使学生观察能力、思维能力、实际操作能力的提高,有利于启发学生积极思维,培养学生分析问题和解决问题的能力.
The Discovery Act, a heuristic teaching method advocated in the teaching reform in recent years, found, as Brunner of the United States said, “to include everything in his own mind to gain knowledge.” However, the word “discovery” It is often misunderstood by people that some people think that primary school students can not even grasp the knowledge that teachers tell them, but let them discover what concepts, laws, laws and formulas are too harsh. In fact, what we call “discovery” is not Instead of asking or expecting students to invent something at once, students are encouraged to use the materials provided by their teachers or textbooks to find out what they deserve, based on what they already know, through independent thinking. Only when students encounter insurmountable Obstacles, teachers give the necessary help and guidance.In the elementary mathematics teaching, the proper use of “discovery method”, can promote the students to observe ability, thinking ability, practical ability to improve, help to inspire students to actively think and train Students analyze and solve problems.
