课程标准中指出,要把培养学生学习化学的兴趣、提高科学素养放在首要的位置,而实验教学是其中重要的一个环节。初中学生刚刚开始学习化学,学习方法及抽象思维能力还没有形成,因而,应从实验的全方位指导,通过各种考查手段和加强学生实验,促进学生科学素养的提高,并且从提高教师自身素质做起。 Curriculum standards pointed out that we should cultivate students interest in learning chemistry, improve scientific literacy on the primary position, and experimental teaching is one of the important links. Junior high school students have just started to learn chemistry, learning methods and abilities to abstract thinking have not yet formed, therefore, should guide from all aspects of the experiment, through a variety of test means and to strengthen students ’experiments, to promote the improvement of students’ scientific literacy, and improve the quality of teachers themselves Start.
