Abstract:

This presentation introduces your students to the rules of comma usage, including placement in compound sentences, after introductory elements, with dependent phrases and clauses, around non-essential elements, in a series, and with adjectives. This presentation also covers methods for avoiding a common comma error--the comma splice. This presentation is ideal for the beginning of a composition course, the assignment of a writing project, or as a refresher presentation for grammar usage.
