通过近几年的科学教学,发现学生对于科学课堂还是很期待,尤其是实验课都表现得非常的积极,但却存在大部分同学参与度不高,表现在主动性差、缺乏有效发言,本文结合评优课教科版小学科学五年级下册《传热比赛》,浅谈如何让科学课堂活跃起来,让学生从被动的接受转变为主动的获取。一、贴合生活,激发兴趣导入片段:师:我现在要倒一杯热水(手故意碰到壶身,假装烫手)哎呀,真烫,谁来帮帮我?师:为什么他没烫到而我却烫到了?
Through science teaching in recent years, we find that students are still very much looking forward to the science class. In particular, the experimental class is very positive. However, most of the students do not participate in the science class actively because of poor initiative and lack of effective speech. Evaluation of excellent textbooks Primary Five Science Volume Two “heat transfer competition”, talk about how to make the science class active, allowing students to change from passive acceptance to active acquisition. First, fit life, stimulate interest into the fragment: Teacher: I now want to pour a cup of hot water (hand deliberately touched the body, pretending to be hot) Oh, really hot, who will help me? Teacher: Why he did not hot yet I’m hot yet?
