The primary focus of this module, one of five to be integrated into an 11th grade American history course, is on the question: Is law necessary? Understandings, or objectives, deal with the use of the law as a necessary means of social control over antisocial behavior and dispute resolution; treat the social guidance function of law; examine the use of law to provide necessary social benefits through public and private means; and give students an opportunity to philosophize about the theoretical neccessity for law. In the module, an explanation for the teacher follows the statement of each understanding. Related objective and general questions are listed. Most of the double-columed pages detail descriptions of classroom strategies with notes to explain a strategy's validity and to indicate points to observe while using the strategies. Resources used with these strategies are grouped together and are cross-reference by case name, statute, and by page in a detailed description of the teaching procedure. A resource listing for each case includes a description or excerpt from the decision. A bibliography includes written source materials as well as films, filmstrips, and simulations. A teacher's guide is SO 007 674. (Author/KSM)
