知识形成的过程,是学生获得体验、产生学习数学积极情感的重要途径。学生只有通过对直接来自现实世界的数据和模型的实践研究,经历数学知识发现、发生和发展的过程,才能让学生头脑中的那些非正式的数学知识和经验升华为科学的结论,从中感受到数学发现的乐趣。一、选取生活素材,有效激发学习兴趣“数学教学如果教师不想方设法使学生产生情绪高昂和智力振奋的内心状态,就急于传授知识,那么这种知识只能使人产生冷漠的态度……学习就会成为学生沉重的负担。”(苏霍姆林斯基)因此,当我们的数学教学选择从学生熟悉的生活情 The process of knowledge formation is an important way for students to gain experience and generate positive emotions in mathematics. Only by experiencing the process of discovery, occurrence and development of mathematical knowledge through the practical study of the data and models derived directly from the real world can students experience the informal mathematical knowledge and experience in their minds as scientific conclusions Math find the fun. First, select the life material, effectively stimulate interest in learning “Mathematics Teaching If teachers do not want to find ways to enable students to generate emotional and intellectual excitement of the inner state, eager to impart knowledge, then this knowledge can only make people indifferent attitude ... Learning It will become a heavy burden on the students. ”(Suhomlinski) Therefore, when our mathematics teaching choose from the familiar life of students
