This curriculum guide is one of nine such guides developed for an Alberta high school business education program. Its content covers the main subject area or strand of law. Subject to the constraints outlined in the guide, the modules are to be formatted into three- or four-credit courses within each strand. Introductory materials include a business education program philosophy, a list of learning principles applied to business education, a list of program objectives, a schematic overview of a business education high school program, course sequences, guidelines for structuring business education courses, and a business education matrix. The materials specifically for Law 20-30 follow: an introduction, objectives, and a flowchart of modules. These components are provided for each of the 10 modules: purpose and a chart that correlates topics with learning tasks and teaching notes. Module topics are the nature of law and civil law system, contract law, family law, basic rights and responsibilities, labor law, property law, criminal justice system, consumer law, tort law, and controversial issues. The guide also contains guidelines for student evaluation, lists of basic and recommended learning resources, and a correlation of course content with learning resources. (YLB)
