This resource book was developed to help home economics teachers reinforce academic principles in mathematics; science, and language arts while teaching essential home economics content. Separate sections of the book are written for each academic area. Each section begins with an overview and update of the academic area based on a review of literature and input from experts. A rationale is given for designating certain skills as fundamental for success and productivity in society, and current instructional trends in each area are discussed. Following this overview, principles are identified that are considered essential to competence in each academic area; they are explained, defined, and elaborated with specific examples. A section on learning and evaluation experiences contains suggestions for applying principles of mathematics, science, and language arts to specific home economics content areas. Suggestions are intended to provide usable activities for classroom implementation, and adaptations for exceptional students are suggested. Educational trends involving integrated instructional approaches, critical and higher-level thinking skills, and cooperative learning are addressed in the final section of the book. Eleven teaching aids (handouts or transparency masters) and 20 references are included. The book is indexed. (KC)
