The first part of this manuscript relates the initial efforts of a teacher who attempted to apply the value clarification approach in an eighth grade social studies class. The approach is based on Louis Rath's seven-part approach to values clarification which encourages children to choose and to prize one's beliefs and behaviors, and to act on one's beliefs. Value clarification techniques used in the classroom take place in a broad methodological framework that begins with readings on Africa and Asia, and continues with discussion of universal topics and short thought papers to instill a particular set of values through the Rath technique. In Part II, the author discusses his concern for the need to develop evaluation tools to assess the effectiveness of the value clarification approach, and the steps he takes to design such formative and summative evaluation instruments. In one case, the author analyzes the data he compiles and then modifies his teaching strategies to increase the effectiveness of the value clarification approach. (Author/JR)
