在课堂教学中,如果字字从书,不敢把教材内容作合理的“弃、改、补”,则未必尽善。反之,一切从实际出发,在慎重考虑的基础上,不妨越大纲与教材这个“雷池”一步,则往往有良好的教学效果。 In the classroom teaching, if the word is from the book and does not dare to make the content of the teaching material “abandon, change, and supplement”, it may not be perfect. Conversely, everything starts from reality, and on the basis of careful consideration, it may be better to go beyond the outline and teaching materials as a “relief pool” step, and there are often good teaching effects.
