Formal grammar pedagogy, the traditional method of teaching grammar, has received largely negative feedback from students and teachers because of its mundane subject matter and presentation. While rhetorical grammar is an alternative to formal grammar, my thesis utilizes both of these pedagogies' strengths: formal grammar's focus on grammatical knowledge and rhetorical grammar's focus on grammatical ability. My project is a classroom lesson that combines formal and rhetorical grammar to show that these two pedagogies must work together to be the best means of improving students' grammar. Specifically, the lesson is a music and punctuation exercise that allows students to experiment with different types of punctuation by translating musical sounds into punctuation marks on lyric sheets. The exercise is followed by a small group and then class discussion in which I teach students the grammar rules for each punctuation mark they use, emphasizing that these rules are specific to a formal context. By incorporating formal and rhetorical grammar in the lesson, my project successfully shows students the differences in writing contexts and how punctuation changes based on that context.
