The document discusses the need for teachers to expand their strategies for helping students comprehend visual images and multimodal texts. It presents three perspectives for analyzing these types of texts: (1) art theory and criticism, which involves analyzing visual elements based on established artistic conventions; (2) grammar of visual design, which examines how meaning is constructed through visual composition; and (3) media literacies, which considers how different media forms convey meaning. The document argues that these additional perspectives can help teachers develop students' interpretive skills for the complex multimodal texts they increasingly encounter.
