國中生正處於青春發育期，特別是國中男生正經歷變聲期。教師透過教導學生認識不同的類型的人聲，讓學生理解並接納自己的聲音特色，進而能夠欣賞不同的人聲類型。期待學生透過本堂課程，對於聲音比較特別的男生或是女生，能夠不要產生性別刻板印象或是歧視。此外，教師透過講述不同時代的聲樂角色，帶入兩性平等的概念。 Junior high school students are in the stage of puberty, especially boys who are experiencing voice changes. Through teaching students about different types of voices, teachers help them understand and accept the unique characteristics of their own voices, enabling them to appreciate various voice types. This lesson aims to prevent students from developing gender stereotypes or discrimination against individuals with unique voices, whether male or female. Additionally, by discussing vocal roles from different historical periods, the teacher introduces the concept of gender equality.
