《九年义务教育化学课程标准》指出的用化学实验的方法学习化学,并在知识与技能、过程与方法、情感态度与价值观方面分别提出了不同要求.这种方法学习化学既符合化学的学科特点也符合学生学习化学的认识特点,是化学教学实施素质教育的基本手段.“实验室制取二氧化碳”就是这样一节课:在教学过程中,教师通过组织学生设计实验,引导其独立操作来帮助学生形成化学概念,理解和巩固化学知识,并培养学生观察能力和思维能力,及培养他们实事求是、严谨的科学态度.现结合“实验室制取二氧化碳”的学习,谈一下我的做法及体会.一、再现旧识,理清思路
The “Nine-year Compulsory Education Chemistry Curriculum Standard” points out the different ways of using chemical experiments to learn chemistry, and puts forward different requirements on knowledge and skills, processes and methods, emotional attitudes and values, respectively. This method of learning chemistry is not only in line with the discipline of chemistry The characteristics are also in line with students’ understanding of learning chemistry, is the basic means of implementing quality education in chemistry teaching. “Laboratory carbon dioxide ” is such a lesson: In the teaching process, teachers through the organization of students to design experiments to guide their independence Operation to help students form a chemical concept, to understand and consolidate the chemical knowledge, and to develop students’ ability to observe and thinking, and develop their realistic and rigorous scientific attitude. Now combined with the “laboratory carbon dioxide” learning, talk about me Practice and experience. First, reproduce the old knowledge, clarify ideas
