教师的教学是以教材内容为依据的。所以,作为一名化学教师,首先应当吃透化学教材。只有真正掌握了教材,吃透了教材,才能在教学当中起到“导航者”的作用。所渭吃透教材:首先是完整系统地掌握教材内容、深刻理解其基本精神,同时,正确运用化学用语也是重要的一环。如果不注重这一点,必将事倍功半。比如,一九八五年某地高中招生化学试题中,有这样一道判断改错题:“硫酸分子是由氢、硫、氧三种元素组成的。”
The teaching of teachers is based on the content of teaching materials. Therefore, as a chemistry teacher, you should first get a thorough understanding of chemistry. Only by truly mastering the teaching materials and getting through the teaching materials can we play a role as a navigator in teaching. The textbooks thoroughly understand: First of all, it is a systematic and systematic grasp of the content of the teaching materials and a profound understanding of its basic spirit. At the same time, the correct use of chemical terms is also an important part. If you do not pay attention to this, you must do less than half the effort. For example, in the high school enrollment chemistry test in 1985, there was such a mistake: “The sulfuric acid molecule consists of three elements: hydrogen, sulfur, and oxygen.”
