abstract:In mathematics, class field theory is a major branch of algebraic number theory that studies abelian extensions of number fields and function fields of curves over finite fields and arithmetic properties of such abelian extensions. A general name for such fields is global fields, or one-dimensional global fields.
Moreover, this paper holds that the constructionismteachingtheory is fit toclass-teachingfield, anddiscusses the idea, method, organization of constructionism teaching.
