化学是一门以实验为基础的自然科学,实验在化学教学中的作用是不容忽视的。新教学大纲在“初中化学教学目标”中除了规定学生需要学习一些化学基础知识和基本技能外,特别突出强调要重视情感领域的教学和对学生能力及创新精神的培养。在教学内容方面,从义务教育实际出发,新大纲适当降低化学基本概念和原理的要求,大幅度降低化学计算的要求,在适当拓宽元素化合物知识面的同时,加强了化学实验,把演示实验列入初中化学实验教学。化学实验可以激发学生的学习化学兴趣,
Chemistry is an experiment-based natural science. The role of experiment in chemistry teaching can not be ignored. The new syllabus in “junior high school chemistry teaching objectives” in addition to the provisions of students need to learn some basic knowledge of chemistry and basic skills, with particular emphasis on the importance of emphasis on teaching in the field of emotion and the cultivation of student ability and innovative spirit. In terms of teaching contents, starting from the reality of compulsory education, the new program appropriately reduces the requirements of basic chemical concepts and principles, drastically reduces the requirements for chemical calculation, and while broadening the knowledge of elemental compounds, strengthens the chemical experiments, Into the junior high school chemistry experiment teaching. Chemistry experiments can stimulate students’ interest in learning chemistry,
