课堂教学的有效性,就是通过课堂教学使学生在知识技能、解决问题、情感与态度方面获得协调发展,有效地实现预期的教学结果。本人结合小学科学学科特点、小学生的特点,以及有效性教学的要求,谈谈在科学课堂中追求有效教学的做法。一、关注学生发展,激发学生兴趣兴趣是学生获取知识的直接动力。科学课要注意培养学生持久的学习兴趣。如在教学《热胀冷缩》时,可先放录像,让学生先观察为什么水会溢出来;把装满水的试管放入热水中,观察水面有什么变化;如果水膨胀了,会出现什么现象; The effectiveness of classroom teaching is to enable students to achieve coordinated development of knowledge and skills, problem solving, emotion and attitude through classroom teaching so as to effectively achieve expected teaching results. I combine the characteristics of primary science disciplines, primary school students, and the requirements of effective teaching, to talk about the pursuit of effective teaching in the science classroom. First, pay attention to student development, stimulate student interest Interest is the direct motivation for students to acquire knowledge. Science class should pay attention to cultivate students’ lasting interest in learning. Such as teaching “thermal expansion and contraction”, you can put a video, so students first observe why the water will overflow; the test tube full of water into the hot water, observe what the water changes; if the water swollen, will What happens?
