This handbook is designed to help educators improve the effectiveness of daily lessons. The need for flexibility and the ability to develop meaningful variety are emphasized. Suggestions and guidelines are provided for writing objectives, planning lessons, and selecting instructional methods. Three major categories of teaching/learning strategies--presentation, action, and interaction techniques--selected because of their resemblance to natural ways of interacting with the environment outside the classroom, are considered in detail. Specific examples and sample lesson plans are provided for lectures, guided observations, demonstrations, audiovisuals, field trips, projects, experiments, exercises, questioning, discussions, brainstorming, seminars, interviewing, role-playing, committees, and debates. The lesson plan format includes lesson objectives, teacher and student activities, equipment and materials, and an outline of the content and procedures for the lesson. (Author/JD)
