《义务教育化学课程标准》指出化学是一门以实验为主的自然科学,学习化学的一个重要途径是实验,而科学探究是一种重要的学习方式,是学生积极主动地获取化学知识、认识和解决化学问题的重要实践活动。提高学生科学探究的能力对发展学生的科学素养有不可替代的作用。因此,在化学实验教学中,如何选好实验、做好实验、用好实验以及对实验的反思与评价、表达与交流,充分发挥实验的探究功能,激发学生学习化学的兴趣及对科学的情感,是化学教师教学的课题。
The standard of compulsory education chemistry curriculum points out that chemistry is an experiment-based natural science. One of the important ways to learn chemistry is experiment. Scientific inquiry is an important way of learning. Students actively acquire chemical knowledge and understanding And solve the chemical problems of important practical activities. To improve students ’ability of scientific inquiry has an irreplaceable effect on the development of students’ scientific literacy. Therefore, in the experiment of chemistry experiment, how to choose experiment, experiment, make good use of experiment, reflection and evaluation of experiment, expression and communication, give full play to the exploratory function of experiment, arouse the interest of students in learning chemistry and the emotion of science , Is a chemical teacher teaching topics.
