This handbook provides valuable information for educators to use in developing a one-semester high school course on economics. The volume includes activity outlines, a model for assessment, and a list of resources to enhance instruction in economics. The handbook identifies methods to enrich instruction using the state-mandated economic component of the California high school curriculum. Chapter 1 reviews the basic components of microeconomics, macroeconomics, economic systems, and international trade as part of the course content. Chapter 2 describes issues-oriented activities to enliven economic concepts. Ten modules provide opportunities to encourage students to study economics through the application of basic concepts. Chapter 3 identifies the conceptual, semantic, and attitudinal hurdles that can interfere with a student's learning of economics. Chapter 4 illustrates a model for the assessment of student learning in a high school economics course. An appendix identifies 53 resources and addresses for further information to enhance high school economics instruction. (CK)
