化学是自然科学的一种,在分子、原子层次上研究物质的组成、性质、结构与变化规律,它是一门以实验为基础的学科。虽然在中考中化学只占一少部分,但是在中学教学中化学却占有至关重要的地位,我们丝毫不能忽视它。它不仅为高中化学的学习打下基础,而且对于日后的生活也有很大的帮助。初中化学教学对很多教师来说一直是件两难的事:一方面教师想通过短短的一年化学学习,让学生在中考中取得高分,就不得不抓要点、抓考点、做练习;另一方面教师想让学生多进入实验
Chemistry is a kind of natural science, which studies the composition, nature, structure and variation of matter at the molecular and atomic levels. It is an experiment-based discipline. Although chemistry makes up only a small part of the middle school examinations, chemistry plays a crucial role in secondary school teaching and we can not ignore it at all. It not only lays the foundation for high school chemistry but also greatly helps in future life. Junior high school chemistry teaching has been a dilemma for many teachers: on the one hand, teachers want to pass a short year of chemistry study, so that students get a high score in the senior high school entrance examination, they have to grasp the key points, test sites, do exercises; On the one hand, teachers want students to experiment more
