课堂是学生学习的主阵地,教师作为课堂的主导者,要确保提供高质量、高效率的课堂教学来促进学生的学习,这是实施新课程的重要保障.如今学生化学学习中普遍存在“我们教得吃力,学生成绩提高不了”的问题,这就需要我们针对学生的学习问题改进学习策略,逐步提高课堂的效率.下面我就谈一下如何构建高中化学高效课堂.一、了解学生原有的认知结构我们在进行课堂教学之前,应该要全面了解学生的原有的认知结构,帮助他们构建一个系统的知识体系,将原有认知和 Classroom is the main front for students to learn, teachers as a classroom leader, to ensure that the provision of high quality and efficient classroom teaching to promote student learning, which is an important guarantee for the implementation of the new curriculum.Now chemistry students are now commonly present We teach hard, students can not improve performance ", which requires us to improve learning strategies for students learning problems, and gradually improve the efficiency of the classroom. Now I will talk about how to build a high school chemical efficient classroom. Some cognitive structure Before we carry out the classroom teaching, we should fully understand the original cognitive structure of students to help them build a systematic knowledge system, the original cognitive and
