教学活动是师生的双边活动,教师是主导,而学生是主体,那么在数学课上如何调动学生的学习积极性呢?心理学研究表明:“浓厚的学习兴趣,可以使学生各种感官、大脑处于最活跃的状态,能够最佳地接受教学信息;能有效地诱发学习动机;能使学生在学习过程中产生愉快情绪。”那么,如何让学生在学习中积极地动口、动手、动脑,参与到学习活动中,成了数学老师当前研究的重要问题。如果在课堂上适当的利用背景故事进行教学就不同了。它不仅 Teaching activities are the bilateral activities of teachers and students, teachers are dominant, and students are the main body. So how to mobilize students’ enthusiasm for learning in math class? Psychological research shows that: “The strong interest in learning can make all kinds of senses, The brain is in the most active state, can receive the best teaching information, can effectively induce the motivation of learning, and can make the students have a pleasant mood in the learning process. ”So, how to make students actively learn, Brains, to participate in learning activities, has become the math teacher’s current study of the important issues. It is different if the appropriate use of background story in the classroom for teaching. It is not only
