This guide, designed for teachers and other workers in adult basic education, includes a variety of articles about teaching; counseling, and advocacy approaches; curriculum planning and evaluation, assessment; and program design based on personal experience. All focus on critical thinking as a teaching and learning skill. Article topics include: (1) an overview of the Critical Thinking Project from which the publication emerged; (2) theory of critical thinking as it underlies practice; (3) descriptions of specific curriculum projects, including curricula on beauty, weight, and nutrition, students' real life dramas, oral history and community art, immigration, and Acquired Immune Deficiency Syndrome (AIDS) awareness; (4) the process of analyzing and solving problems; and (5) assessing Spanish literacy. Also included are interviews with a teacher and a student in a program for women, rooted in the black community, that examine critical thinking as an educational priority and how critical thinking is interpreted, taught, learned, and practiced.
