“圆的面积”一课,如果让学生积极主动地参与知识形成的全过程来获取知识,把学习主动权还给学生,让学习问题自然生成,提高学生的归纳、推理的数学思维能力,我们会发现孩子们的思维是多么广阔,学生在获得知识的同时,创新意识、探究能力和实践能力都得到发展。首先,知识目标要明确,知道圆的面积的含义,理解和掌握圆的面积计算公式,能正确地运用公式计算圆的面积。其次,要通过小组学习、动手操作,主动探索等活动,
“Circular area” class, if students are actively involved in the whole process of knowledge formation to gain knowledge, give learning initiative back to students, let learning problems arise naturally, improve students’ mathematical thinking ability of induction and reasoning We will find out how broad the children’s thinking is. Students acquire knowledge while their awareness of innovation, their ability to explore, and their ability to practice have all developed. First of all, the knowledge goal should be clear, we must know the meaning of the area of the circle, and understand and grasp the circle area calculation formula. We can use the formula to calculate the area of the circle correctly. Second, through group learning, hands-on operations, active exploration, etc.
