一、质疑是培养学生探究能力的前提质疑并提出问题是探求知识、发现问题的开始,是一种可贵的探索精神。学生走进教室,并非是从零开始的,对书本上涉及到的一些数学知识有的已初步了解,容易在学习活动中产生疑问。教师必须为学生“疑”的释放创设空间,让他们自由地发问,大胆地怀疑、猜想、批判。不论学生质疑的问题是否有深度,是否 First, the challenge is to train students to explore the premise of the ability to question and ask questions is to explore knowledge, find the beginning of the problem is a valuable exploration of the spirit. Students into the classroom, not from scratch, some of the mathematical knowledge involved in the book has some initial understanding, easy to question in learning activities. Teachers must create room for the release of students “doubt ” so that they can freely question, dare to doubt, guess, criticize. Whether or not the questions the students are questioning are deep, are they?
