《义务教育化学课程标准(2011年版)》指出:“义务教育阶段的化学教育,要激发学生学习化学的好奇心,引导学生认识物质世界的变化规律,形成化学基本观念。”宋心琦教授认为:“中学化学教学能够使学生终身受益的不是化学专业知识,而是影响他们世界观、人生观和价值观的化学思想观念,学生能否牢固地、正确地,哪怕只是定性地建立起基本的化学观念应当是化学教学的第一目标。”近年来,我注重化学观念教学的研究,探索以观念构建为本的教学设计与实施的基本思路,努力使自己的课堂教学体现观念为本的教学理念。
“Compulsory Education Chemistry Curriculum Standard (2011 Edition)” points out: “Compulsory education chemistry education, to stimulate students to learn chemistry curiosity, to guide students to understand the changing laws of the material world, the formation of the basic concepts of chemistry.” Professor Song Xinqi that : “Chemistry teaching in secondary schools can not benefit students’ chemistry for a lifetime, but is a chemical thinking that affects their world outlook, outlook on life and values. Can students sturdy, correctly and even qualitatively establish basic chemistry The concept should be the first goal of chemistry teaching. ”" In recent years, I have paid great attention to the study of chemistry concept teaching, explored the basic idea of teaching design and implementation based on concept construction, and tried hard to make my class teaching reflect concept-based teaching idea.
