Two papers are presented--a summary and a lengthier description of an interdisciplinary college-level liberal arts course. Both papers are intended for use by humanities and social science teachers as they develop and implement interdisciplinary and competency-based curricula. Five areas of academic competency serve as course objectives. These are that students should: (1) be acquainted with purposes, methods, and nature of evidence in humanities and social sciences; (2) have practice in critical thinking; (3) be able to use resources in humanities and social sciences; (4) be aware of the history, major findings, current state, and directions of inquiry in the two fields; and (5) be able to conduct independent inquiry and communicate effectively in oral, written, and visual forms. Course activities involve students in a social science research project, a humanities research project, and a mastery project which involves methods of inquiry from both the social sciences and the humanities. In the social science project, students are directed to answer a question about classroom learning using behavioral observation, survey, statistical analysis, and cultural analysis. In the humanities project, students are directed to use introspection, comparison, and logical analysis in a study of human imagination and creativity. For each project, information is presented on instructional strategies, evaluation methods, and possible research topics. (Author/DB)
