动手实践、自主探索、合作交流是学生学习数学的重要形式,它除了使学生获取知识外,更重要的是能获得学习经验,掌握要领,拓宽思路。然而时下的数学课堂仍普遍存在一味地给学生灌输知识的现象,教师总是怕学生听不懂,看不懂,不会做。这样,就算学生掌握了知识的全部,也不能很好地利用知识来解决生活实际问题,因而,自主探索学习就显得尤为重要了。一、创设情境课堂教学是教师与学生,学生与学生间的一种多向的信息 Hands-on practice, self-exploration, cooperation and exchange are important forms of learning mathematics for students. Apart from enabling students to acquire knowledge, more importantly, they can acquire learning experiences, master essentials and broaden their thinking. However, there is still a common phenomenon in current mathematics classrooms to instill knowledge into students. Teachers are always afraid of students who can not understand, do not understand or do not do anything. In this way, even if students master all the knowledge, they can not make good use of knowledge to solve practical problems in life. Therefore, it is particularly important to study independently. First, the creation of contextual classroom teaching is a multi-directional information between teachers and students, students and students
