化学教学是一个多要素的复杂的系统过程,要想将这一复杂过程在具体教学活动中灵活多样地运用,在课堂教学之前,教师必须对课堂教学进行很好的设计,保证教学取得较好的效果。《物质的量》这一章是整个高中化学的重点也是难点,它使得化学在量的研究上产生了质的飞跃,因而对它的教学设计显得尤为重要。 Chemistry teaching is a multi-factor complex system process. If we want to use this complicated process flexibly and flexibly in specific teaching activities, teachers must design classroom teaching well before class teaching to ensure better teaching Effect. The chapter “The Quantity of Matter” is a key and difficult point in the chemistry of the entire high school. It has made a qualitative leap in the amount of chemistry that makes it particularly important for its instructional design.
