高三的学生对元素化合物知识、氧化还原反应、离子反应的规律、化学反应原理(如化学反应限度、电化学等)已有了一定的积累;具备一定的实验操作技能和合作、交流能力,能对实验现象及结果作出初步分析、推理、归纳的能力.但是元素化合物知识的结构化、系统化还存在缺陷;未能有效运用离子观、平衡观、定量观等化学基本观点解决问题;设计和评价实验的能力尚待提高.
High school students have a certain accumulation of knowledge of elemental compounds, redox reactions, ionic reaction laws, chemical reaction principles (such as chemical reaction limits, electrochemical, etc.); have some experimental skills and cooperation, exchange ability, can The preliminary analysis, reasoning and inductive ability of the experimental phenomena and results are made, but the structural and systematization of elemental compounds are still flawed. Problems such as ion view, equilibrium view and quantitative view can not be solved effectively. The ability to evaluate experiments needs to be improved.
