论文部分内容阅读
从2008年新课程实施以来,我对《氧化还原反应》的教学进行了许多探索研究,对这部分内容有了一个全新的认识。我在进行人教版高中化学必修1《氧化还原反应》的新授课教学时主要围绕三项任务:一是让学生从初中氧化还原反应得氧、失氧角度的认识过渡到高中电子转移的角度,继续学习氧化还原反应;二是初步掌握氧化还原反应的几组概念;三是通过练习巩固概念的学习。本节课以知识学习为载体,更多体现的是对学生科学素养的培养。如贯穿始终的概念发展的观点,对立统一的观点,分析问题、应用所学概念解决问题的能力。整堂课中学生在教师的分步指导下围绕目标,积极的阅读、思考、分析、纠错,在学习中应用,在应用中学习。
Since the implementation of the new curriculum in 2008, I have made a lot of exploration and research on the teaching of “redox reaction”, and have given a totally new understanding to this part. When I was teaching PEP 1 high school chemistry compulsory 1 new teaching “redox reaction” teaching mainly around three tasks: First, students from the junior high school oxidation-reduction reaction oxygen, oxygen angle of understanding transition to high school electron transfer point of view , Continue to learn the redox reaction; the second is to initially grasp the concept of several groups of redox reactions; the third is to consolidate the concept of learning through practice. This lesson to knowledge-based learning, more reflect the cultivation of students’ scientific literacy. Such as the consistent view of conceptual development, the unity of opposites, the analysis of problems and the application of concepts learned to solve problems. The whole class of students around the target under the guidance of the teacher step by step, positive reading, thinking, analysis, correction, application in learning, learning in application.
