Developed by the Special Education Supervisor Training (SEST) Project at the University of Texas at Austin, the document examines two instruments and basic procedures for observing and analyzing individualized instruction. Guidelines are provided for self training and training others in the use of the Individualization of Instruction Inventory (III) and the Descriptive Observation Record for Individualization of Instruction (DORII). The DORII is said to be composed of five sections concerning intraclass grouping, materials, pupil autonomy, student assignments, and tutoring. Intended to be used as a supplement to the DORII, the III is a rating scale which permits quantification of observed behavior. Ten procedures for using the two instruments are listed, problems in recording and scaling responses are discussed, and feedback practices are considered. Training aspects are examined in terms of preliminary activities (with three sample sessions described), and in-classroom observation training. Additional information is provided on inter-observer reliability, data storage, retrieval and display for feedback. Among nine appendixes are sample DORII and III forms, and a profile for individualization. (CL)
