化学课程教学是高中教育阶段一门重要的理科类课程,对学生今后的学习和发展具有重要的基础性作用。同时,高中化学由于其“繁、难、乱”的特点一直以来影响学生学习的积极性,导致大部分学生学习成绩不理想。让很多教师感到头疼。本文主要结合高中化学课堂教学特点,探讨了优化课堂效率,提高课堂有效教学,从而提高学生化学学习的兴趣,达到全面发展的目的。 Chemistry course teaching is an important science course in high school education, which plays an important fundamental role in the students’ future study and development. At the same time, high school chemistry has always affected the enthusiasm of students due to its “complex, difficult and chaotic” characteristics, resulting in unsatisfactory results for most students. Many teachers feel a headache. In this paper, the characteristics of high school chemistry classroom teaching are mainly discussed to optimize the classroom efficiency and improve the effective teaching in the classroom, so as to enhance students’ interest in chemistry learning and achieve the goal of all-round development.
