新课程改革目的在于提升学生的基本化学素养,化学的教学目标更加丰富.新课程从学生的个性发展角度出发,提出了“知识与技能、过程与方法、情感态度与价值观”三维教学目标,相比于传统单一的知识目标而言,更加全面,更能促进学生的全面发展.那么如何具体地落实“三维目标”呢?笔者认为必须从学生的思维特点和化学学科特点出发,在中学化学教学中,实验教学是至关重要的一部分.实验教学包括两部分:演示实验和学生实验.教师的演示实验操作简便、现象显著,直观性较
The new curriculum reform aim is to enhance the students ’basic chemistry accomplishment, the chemistry teaching goal is richer.The new curriculum puts forward the three-dimensional teaching goal of “knowledge and skill, process and method, emotion attitude and value” from the perspective of students’ personality development , Compared with the traditional single goal of knowledge, more comprehensive and more to promote the all-round development of students.How concretely to implement the “three-dimensional goals”? I believe that students must be thinking characteristics and characteristics of chemistry, In middle school chemistry teaching, experimental teaching is a crucial part.Experimental teaching consists of two parts: demonstration experiment and student experiment.The demonstration of teacher is easy to operate, the phenomenon is obvious and the visualization is more
