10、2)利用字典，自主识字。由于中年级的学生具有一定的独立识字能力，识字方式上可以做进一步的调整。认字可以让学生自学完成。老师在学生自学的基础上进行检查，可以对多音字、难读准的生字或易混的生字作指导。在教学中，教师要引导学生用多种识字方法识记生字。老师应该鼓励学生通过各种渠道主动识字，扩大识字量并养成独立识字的习惯。精品w o r d 可编辑资料-第 3 页，共 20 页-文档编码:CB10M6F9F3D5 HO7T2I1Q8O5 ZY5B9J4S2Z7文档编码:CB10M6F9F3D5 HO7T2I1Q8O5 ZY5B9J4S2Z7文档编码:CB10M6F9F3D5 HO7T2I1Q8O5 ZY
