This unit of study for high-ability language arts students in grades 2-3 uses an inquiry-based approach to investigate literature in an interdisciplinary curriculum. The guiding theme of the unit is the recognition of change as a concept that affects people and their relationships as well as the world around them. The unit provides the vehicle for student participation in activities that elicit examination of physical and behavioral changes in individuals and in relationships. An open-ended approach to the discussion process emphasizes the search for meaning in literature. Vocabulary and grammar development supports the readings as well. Students consider the role of memory in their lives, through writing about memories and through research on the role of technology in preserving memories. The unit is designed to improve students' critical reasoning related to comprehension of the main idea of a selection, understanding of the concept of change, and supporting an answer with valid reasons. This guide presents goals and outcomes, a list of student readings, an assessment model, a paper analyzing the concept of change, teaching models, 21 lesson plans, assessment forms, a list of almost 100 works taught in the unit and resource materials used in its development, an annotated bibliography of 28 items on the concept of change, and a list of 41 computer software resources.
