This document provides an overview of the lesson development process. It discusses determining language structures and functions, types of lesson plans, and using questioning strategies. The key steps in lesson development are to formulate objectives, determine how to teach the content using strategies and materials, and evaluate whether students are learning with assignments. Language functions are specific uses of language like apologizing or explaining, while structures refer to grammar elements. Lesson plans can vary in detail from skeletal to detailed formats. Questioning can be used to develop lessons through five stages of language acquisition from pre-production to advanced fluency. Developing lessons should integrate multiple intelligences and learning styles.
