精编教师个人新课标学习心得体会优选例文
我将根据新的语文能力实践系统，致力于学生语文综合素质的提高，促进语文课程的呈现方式和学生学习方式的转变，确立学生在学习中的主体地位，努力给学生创造一个有利于素质教育的空间。 对于小学语文教学来说，既要转变教的方式又要转变学的方式，培养和形成“自主、合作、探究”的学习方式，在这两个转变中，教的方式转变是主要矛盾。教的方式一转变，学的方式也随之转变。学的方式转变可以理情地在课堂中呈现，证明教的方式转变，证明教师新理念的真正树立。课改实践告诉我们，没有坚定的新课程理念，真正意义上的教与学方式的转变是不可能的。把课标学习与教材教法研究结合起来：要钻研新教材，理解和把握新教材，用好新教材，要重视教学反思，个案研究和收集，要牢记验证课标和检验教材的实验任务。
