小学科学实验关键是学生必须通过亲身体验实验的过程获取知识和培养科学的素养。在平时科学实验探究活动中,学生对实验重视不够,认为实验就是做游戏图热闹,全员参与意识不强,实验处于无序状态,造成实验的低效现象。结合多年的教学实践,认为必须要改变教学策略来真正提高科学实验的有效性。从“创设学习情境,激发探究兴趣;选择合适材料,方便实验操作;选择合适方法,引导实验有序开展;运用多种评价手段,养成科学素养等方面来进行研究,提高课堂实验教学的有 The key to primary science experiment is that students must acquire knowledge and cultivate scientific literacy through the process of experiencing experiments. In the usual scientific experiment exploration activities, students pay insufficient attention to the experiment, that the experiment is to make the game graph lively, full participation of consciousness is not strong, the experiment in a disorderly state, resulting in inefficient experiments. Combined with years of teaching practice, we think that teaching strategies must be changed to really improve the effectiveness of scientific experiments. From ”to create a learning situation to stimulate interest in exploring; select the appropriate materials to facilitate experimental operation; select the appropriate method to guide the orderly conduct of the experiment; using a variety of evaluation tools to develop scientific literacy and other aspects of research to improve the classroom experimental teaching Have
