课例《众数、中位数》较好地贯彻了义务教育数学课程标准所倡导的理念 :教师要鼓励学生自主探讨与合作交流 ,应引导学生主动地从事观察、实验、猜测、验证等活动 .该节课中至少有 2 1位学生参与了课堂讨论 ,通过讨论、交流 ,认识了数学对象 .但课例提供的穿插在学生发言中的教? The “majority and median” class lesson implements the concept advocated by the compulsory mathematics curriculum standards. Teachers should encourage students to explore and cooperate independently. They should guide students to actively engage in activities such as observation, experimentation, guessing, and verification. At least 2 students in the class participated in the class discussion. Through discussions and exchanges, they met the mathematics object. However, the lesson examples provided were interspersed with teaching in the students’ speech.
