教学有法,而无定法。在如今的课堂教学中,同课异构作为提高教师教研水平的重要形式已被广泛应用,并取得了很好的教研效果。同时,这种教研形式也道出了一个深刻的哲理:在“同课”的主题探究上,表现出“教学有法”;在“异构”的课堂设计上表现出“教无定法”。本文以人民音乐出版社高中《音乐鉴赏》第16单元第28节《聂耳》同课异构为例,试探讨其中所蕴含的“教学有法,而无定法”的深刻哲理。 Teaching law, but no fixed method. In today’s classroom teaching, the heterogeneous structure of the same class has been widely used as an important form to improve the teaching and research level of teachers, and has achieved good teaching and research results. At the same time, this form of teaching and research also revealed a profound philosophy: in “the same lesson” on the theme of inquiry, showing that “teaching is legal”; in the “heterogeneous” classroom design showed “Teaching no law ”. This paper takes the example of the same lesson “Helena” in Section 28 of “Unit 16 of Music Appreciation” of People’s Music Publishing House as an example to probe into the profound philosophy of “teaching with law and not finalization” contained in it.
