提高教师教学水平的方法不胜枚举，且各有所长，各显神通。其中， 教学反思便是有效方法之一。本文从高中化学教学的实际出发，对高中化学教学 反思的意义、方法进行简要阐述。 一、教学反思的定义和意义 1、教学反思的定义 反思，即人们对自己的认识和行为的内化过程，是对自己的思维过程、思维 结果进行再认识和检验的过程。教学反思，是指教师在教学实践中，自觉地把自 己的课堂教学实践作为认识对象而进行全面而深入的思考、分析和总结的过程， 是一种通过提高参与者的自我觉察水平来促进能力发展的途径。 2、教学反思的意义 通过反思,可以使人对一个问题能从多方面考虑、进行广泛深入地思考和选 择。通过反思，能使人发现自己和他人原有认识的错误和不足，从而从旧的模式 中解脱出来，迅速寻找到解决问题的途径。反思是对学习过程本身的认识，包括 知识的形成过程、学习方法及获得结论。反思可以提高沟通新旧知识的联系，促 进知识的同化和迁移；可以拓宽思路，优化解法，完善思维过程。通过对自己的 教育实践进行深入反思，积极探索 和改进教学实践，从而不断完善自身素质，提高教学水平。 (1)促进教师全面思考，提升教学高度，明确教学方向 side roadsubgrade 2m.

在此基础上， 还需要对所思考的内容进行逻辑化、条理化、理性化的表述，又提升了思考的理 性高度，从而进 一步明确教学方向。 (2)促使教师深入学习，完善教学方法，提高课堂效率 针对教学反思中发现的问题，教师的必然要通过学习和思考来找出解决的办 法。由此形成良性循环，促使教师深入持久地学习，并将自己的思考与与相关的 教学理论学习结合起来，不断改进和完善教学方法和技巧，提高课堂教学效率。 (3)提升教师理性性认识，积累教学经验,增强发展后劲 进行教学反思，能够帮助教师把教学实践中的经验、问题和思考积累下来， 对典型事例和思考留下深刻的记忆，并逐步积累，由感性认识上升到理性认识。 使之成为有丰富教学经验和善于理性思考的教师，为教师不断提高教学水平奠定 坚实的基础。 二、教学反思的方法 1、转变教学观念 教师是教学过程的主导者，新形势下，教师的教学观念必须适应教育发展和 教学实际的需要。在进行教学反思的时候不仅要对采取了哪些教学行为进行批判 性的思考，而且要对支配这些教学行为的潜在的教学观念进行重新认识。高中化 学教学的任务是要贯彻全面发展的方针，提高学生的素质，为国家培养合格的公 民。为此，教师也需要对自己教学活动中所体现出来的教育观、课程观、学生观、 评价观进行反思。

教师的观念必须从化学教学向化学教育转变，即从注重具体的 side roadsubgrade 2m.
