要搞好化学教学中的“精讲多练”,我认为要充分认识“双基”教学的重要性,才能提高“精讲多练”的自觉性。用精讲多练的方法,才能保证掌握“双基”,有利于培养学生的能力。掌握了“双基”,就能适应题目的千变万化,就能提高教学质量。 In order to do a good job in teaching chemistry, “I speak intensively and practice more.” I think that we must fully understand the importance of “double-based” teaching in order to improve the consciousness of “extensive teaching and practice”. With sophisticated methods, it is possible to ensure the mastery of “dual bases” and to develop students’ abilities. Having mastered the “double basis”, it will be able to adapt to the ever-changing issues and improve the quality of teaching.
