对于教学难点的理解,我们不仅要参看教学参考书罗列的内容,更要深入到学生的学习过程了解学生的学情。只有把学生认知上的偏差以及知识运用过程中的种种错误也列为教学难点,并在教学中逐一加以解决,才能更好地帮助学生提高对知识的理解力,尤其是提高知识运用的正确性和准确率,真正地把提高课堂教学质量落在实处。 For the understanding of teaching difficulties, we not only have to refer to the contents listed in the teaching reference books, but also to understand the learning process of students learning process. Only when the students’ cognitive deviation and the mistakes in the process of using knowledge are listed as teaching difficulties and can be solved one by one in the teaching can we help students to improve their understanding of knowledge, especially to improve the utilization of knowledge Sex and accuracy, really improve the quality of classroom teaching.
