一、利用多媒体信息技术,优化自主预习,激发学习兴趣。“懂得学习的人,不如喜爱学习的人;喜爱学习的人,不如以学习为乐趣的人,学生没有积极性的课堂绝不是好课堂。”要上好一堂数学课,必须让学生知道这节课学什么,现在我区倡导新的教学模式,要求学生先预习,然后在创设问题的指引下自主学习,多媒体信息技术在这个方面起着举足轻重的作用,不仅可以清晰地展现教学要求,而且可以千变万化地呈现出预习提示,给学生的自主学习指明方向。 First, the use of multimedia information technology, optimizing self-preparation, stimulate interest in learning. “People who learn to learn are not as good as those who love learning. People who love to learn are not as good as learning to be fun, and students who are not motivated are not good classes.” To take a good math class, students must know it What lesson to learn, and now my district advocate a new teaching model, requiring students to preview, and then create the problem under the guidance of independent study, multimedia information technology in this area plays a decisive role, not only can clearly demonstrate the teaching requirements, and Can be presented in a variety of preview hints, to the students to specify the direction of independent learning.
