Designed as part of a 40-hour course on adult residential care homes (ARCH's), this lesson plan was developed to explain the importance of and correct procedures for charting (i.e., keeping a written record of observations and care of ARCH residents). The objectives of the 50-minute lesson are to enable students to: (1) list reasons why the charting of residents' behavior and client care is important in ARCH functions; (2) describe the Problem Oriented Recording System; (3) explain the SOAP (Subjective Objective Assessment Plan) format for recording client progress; and (4) demonstrate the charting technique for a given situation. The lesson plan includes information on the course for which the lesson was designed; equipment and audiovisual aids needed; requirements for student materials; lesson objectives; bibliographic references; and special remarks for the instructor. Next, a step-by-step outline of the instructor's presentation is provided in a format indicating the length of time and the equipment or other aids necessary for each step of the lesson. Handouts and flip chart and transparency masters are included. (PAA)
