首先,抓住“双基”,处理好教材,注意培养能力。如何解决难点、突出重点,注意能力培养?比如摩尔这一章,摩尔浓度是重点,要合理安排时间,精打细算,不能平均用力。按教学原计划要用四周完成。过去对摩尔概念的教学,总是多次单调重复。而讲到摩尔体积与摩尔浓度又在重复已知教材。现在注意抓住了摩尔概念这个重点,突破难点,并解决好有关计算。因此仅用三周时间授完本章,省下较多时间复习提高。同时注意全章的贯通、综合分析,有利于学生能力的培养。
First of all, we should seize the “double base” to handle the textbooks and pay attention to the ability to cultivate. How to solve difficulties, highlight key points, and pay attention to ability training? For example, Moore’s chapter, the molar concentration is the key point, we must make reasonable arrangements for time, careful budgeting, and cannot use average force. According to the original plan of teaching, it must be completed in four weeks. In the past, the teaching of the Moore concept has always been repeated monotonously. And when it comes to molar volume and molarity, it repeats known textbooks. Now pay attention to the key concept of Moore, break through the difficulties, and solve the relevant calculations. Therefore, this chapter is only completed in three weeks and saves more time for review and improvement. At the same time, attention should be paid to the thoroughness and comprehensive analysis of the whole chapter, which is conducive to the cultivation of students’ abilities.
