随着我国新课程改革的不断深入发展,对初中化学的课堂教学要求越来越高,初中化学课堂教学应该顺应新课改的要求,对当前初中化学课堂教学进行创新和改革。想要顺应新课改的要求,全面提升初中化学课堂教学效率,就必须为学生构建一个轻松、愉悦、和谐、充满活力的课堂教学环境。因此,“先学后教”教学模式应时而生,并且在实际的初中化学课堂教学中获得非常好的效果。“先学后教”模式的应用不仅满足了新课改的要求,也为提升初中化学高效课堂奠定了基础。基于此,针对初中化学“先学后教”教学模式的有效性进行了详细的研究和讨论。
With the continuous deepening of new curriculum reform in our country, the requirements for classroom teaching of junior high school chemistry are getting higher and higher. The junior middle school chemistry classroom teaching should conform to the requirements of the new curriculum reform and innovate and reform the current middle school chemistry classroom teaching. In order to meet the requirements of the new curriculum reform and improve the teaching efficiency of junior high school chemistry classrooms in an all-round way, we must construct a relaxed, pleasant, harmonious and energetic classroom teaching environment for students. Therefore, the teaching mode of “prior learning and post-teaching” emerges as time goes by, and achieves very good results in practical junior middle school chemistry classroom teaching. The application of the mode of “learning before teaching” not only meets the requirements of the new curriculum reform, but also lays the foundation for enhancing the chemistry efficient classroom in junior high school. Based on this, a detailed study and discussion is made on the effectiveness of junior high school chemistry teaching mode.
