In a sixth-grade unit, students learned about people's facial expressions through careful observation, recording, reporting, and generalizing. The students studied the faces of people of various ages; explored "masks" that people wear in different situations; learned about the use of ritual masks; made case studies of individuals to show facial changes that occur with mood changes; studied different facial expressions that people use as one way of manipulating others; related facial expressions to the ego states described in transactional analysis; and studied the relationships between facial type and ancestral background. Throughout the unit the children were encouraged to verbalize about their findings. In addition to expressing their findings in journals, letters, essays, descriptions, plays, poems, and a class booklet, the children employed fabric collages, a slide presentation, charts, pantomime, and plaster-of-paris masks in reporting their conclusions to others. The teacher, as facilitator, poser of questions, and resource person, performed as a catalyst to enhance such interacting forces as the environment, books, and other people. (GW)
