初中化学新课程标准提出,要注意从学生已有的经验出发,让他们在熟悉的生活情景和社会实践中感受化学的重要性,了解化学与日常生活的密切关系,让学生逐步学会分析和解决与化学有关的一些简单的实际问题.化学是一门研究物质的组成、结构、性质、以及变化规律的科学,而认识基础之一,就是生活经验中对物质及其变化的认识与了解.在教学设置中,到初三才设立化学这门课程,就是因为学生已具有一定的化学生活经验.在此基础上,如果教师教授化学时能够从学生的这些体会中提取出合适的材料,或者将讲授的化学原理应用于这些日常生活经验中,不仅能
Junior high school chemistry curriculum standards put forward, we should note that starting from the students already experienced, so that they familiar with the life scenarios and social practice to feel the importance of chemistry, chemistry and daily life to understand the close relationship so that students gradually learn to analyze and solve Some simple and practical problems related to chemistry.Chemistry is a science that studies the composition, structure, nature, and changing law of matter, and one of the foundations of understanding is the understanding and understanding of matter and its changes in life experience. In the teaching setup, the course of chemistry was not established until the third day because the students already had certain experience in chemical life. Based on this, if a teacher teaches chemistry, the appropriate materials can be extracted from the students’ experiences or the teaching The chemical principles applied to these everyday experiences, not only
