高中新教材中的元素化合物知识虽然比旧教材精简,但由于这方面知识的感性成分较多,免不了给人以散乱感,学生不易记忆,更不易灵活运用。为了更好地使学生学好和灵活运用元素化合物知识,抓住转化关系图及“位-构-性”和“结构-性质-用途-制备-保存”两条主线,开展模式化教学,促进化学知识的整体建构,以反思教学模式(如编题作业和问题兴趣小组活动)促进知识的有效建构。
Although the knowledge of elemental compounds in new high school teaching materials is more streamlined than the old teaching materials, because of the more sensory components of knowledge in this aspect, students are inevitably given a sense of casualness, students are hard to remember and less flexible to use. In order to better enable students to learn and flexibly use the knowledge of elemental compounds, we should grasp the transformation diagram and the two main lines of “structure - property - use - preparation - preservation” Teaching and promoting the overall construction of chemical knowledge so as to promote the effective construction of knowledge through reflection on teaching modes (such as editing and assignment interest group activities).
