统编高一化学课本第四章《氮族》是学生学完第三章《物质结构、元素周期律》之后所学到的第一个元素及化合物内容。从统编教材的“原、周、分”体系来看,讲授一个新的元素族,就应当充分运用结构理论的基本观点,结合已学过的元素族与周期律,努力提高和加深学生对元素和化合物知识的理解。尽管统编教材在这方面做了一定的努力,但总的看来还是不够的。我认为,作为学完第三章《物质结构,元素周期律》后的第一个元素及化合物的教材内容,在教学中应把物质结构作为主线,鲜明地体现出来。因此,对本章教材内容来说,用结构理论解释元素及化合物的某些性质的内容,应尽量叙述得细致和具体一些,以作为学生遇到类似问题时解题的示范;同时,也可以使学生认识到,只有用结构理论作为统帅,才能更好地学好元素及化合物的知识。下面我就谈谈对这章教材在教学中几个具体处理意见,不当之处,请批评指正。
The compilation of the first year chemistry textbook Chapter IV “Nitrogen family” is the first element and compound content learned after the third chapter of “material structure, periodic law of the elements”. From the system of “original, week and minute” of the textbook, if we teach a new elemental family, we should make full use of the basic theory of structural theory, try our best to improve and deepen the students’ Understanding of elements and compounds. Although the compilation of teaching materials in this area has made some efforts, but in general it is not enough. In my opinion, as the first element after the completion of Chapter III, “Material Structure, Periodicity of Elements,” and the contents of the teaching materials of the compounds, the material structure should be the main line in teaching, clearly reflected. Therefore, for the content of this textbook, structural elements that explain certain properties of the elements and compounds should be described as detailed and specific as a solution to problems encountered when students encounter similar problems; at the same time, Students recognize that knowledge of elements and compounds can be better learned only by using structure theory as commander. Here I will talk about this chapter teaching materials in the teaching of several specific views, inappropriate, please criticism.
