This conclusion summarizes answers to questions about the role of grammar in language arts and English classrooms. It states that grammar can support learning in all language skills when taught as a metalanguage to discuss words and sentences. It suggests eliciting grammar points from students by asking them to provide examples, identify patterns, and form rules and definitions. It also argues that all languages and varieties have grammar, and teachers should respond to students' language as demonstrating richness in patterns rather than focusing only on errors.
