我在长期的教学实践中,体会到在开展数学活动课中,重视小主持人的作用十分重要。重视活动课中小主持人的作用与培养,是调动学生积极性的一个途径,一堂活动课的整个过程应该是一个以学生自已设计安排的自我活动为主的过程。为了突出活动课以学生为主的特点,选择小干部担任主持人的角色,不失为一种好的形式。由于小主持人本身的素养对一堂数学活动课的质量有着至关重要的影响。因此,我们必须重视对活动课中小主持人的挑选和培养。其作用在于:(1)小主持人是活动课的组织者,是同学的小 In my long-term teaching practice, I realized that it is very important to attach importance to the role of a small host in the course of carrying out mathematics activities. Pay attention to the role and training of the small host in the activity class is a way to mobilize the enthusiasm of students. The whole process of an activity class should be a self-centered process based on the student's own design. In order to highlight the activities of the class-based student characteristics, choose a small cadre as the host role, after all, a good form. Because of the quality of a small host, the quality of a math class has a crucial impact. Therefore, we must attach importance to the selection and training of the small host in the activity class. Its role is that: (1) a small host is the activity class organizer, is the classmate's small
