The methodologies employed in the communication/language objectives-based system (C/LOBS), which supports the front-end analysis efforts of the Defense Language Institute Foreign Language Center, are examined. The C/LOBS project, which is described in 13 volumes and an executive summary, functions as a subsystem of the instructional systems development approach currently in use in the TRADOC school system. C/LOBS was designed to develop a systematic set of procedures for determining terminal skill objectives and their supporting enabling objectives for foreign language training. Five job/duty positions and three languages were selected for field testing and system validation. Part one of this volume presents the rationale and methods used in the statistical computer analysis of the language use data supplied by jobholders in a post-interview survey. It discusses calculation by hand and by computer, describes the circumstances in which each is most appropriate, and gives directions for each approach. Part two of the volume presents samples of the instruments used in the collection of data on language requirements of jobholders. (SW)
