现代教学理论研究指出,产生学习兴趣的根本原因是问题。没有问题也就难以诱发和激起求知欲,教学实践证明,创设良好的问题情境可以激活学生的求知欲,促使学生为问题的解决形成一个合适的思维意向,从而收到最佳的教学效果。把问题解决引入课堂不仅是数学教学的一种趋势,而且将会有效地促进学生由被动、单一地学习向自主、实践、探索、合作的学习转变,提高学习效率。
The research of modern teaching theory points out that the root cause of learning interest is the problem. It is difficult to induce and arouse curiosity without any problems. Teaching practice has proved that creating a good problem situation can activate the curiosity of students and encourage students to form a suitable thinking intention for the solution of the problem so as to receive the best teaching effect. The introduction of problem solving into the classroom is not only a trend of mathematics teaching, but also will effectively promote students’ learning from passive and single learning to autonomous, practical, exploratory and cooperative learning and improve their learning efficiency.
