This manual consists of lesson plans developed to train data collectors in the use of the Teacher Performance Assessment Instruments (TPAI). Each set of plans was designed for one of three purposes. Lesson plans developed for the Teaching Plans and Materials Instrument (TPM) simulate a portfolio prepared by the teacher. One-day plans developed for use in conjunction with videotapes for rating the Classroom Procedures and Interpersonal Skills Instruments (CP/IS) represent the classroom activities depicted in videotapes. Lesson plans developed for use with the TPM and CP/IS represent a portfolio prepared by the teacher and are accompanied by a videotaped lesson taught from the plans. The TPM and CP/IS plans were designed to simulate an actual teacher assessment as closely as possible. The plans were created for health, reading, mathematics, science, history, geography, language arts, social science, consumer economics, and English lessons and encompass kindergarten through grade language arts lesson. In addition to the actual lesson plan, simulated decisions involve several classroom factors, including the age and ability range of the class, socioeconomic distribution, demeanor, interest and involvement of students, and prior relevant material studied. For a guide to interpreting the TPAI, see TM 008 013. (Author/JAC)
