A comprehensive guide for observers using the Pupil Activities Record--Revised (PAR-R), this manual covers procedures followed in systematic observation of a student's classroom activities for the period of one instructional day. The manual provides general information about the purpose and design of the PAR and explains the revisions, which were made in order to collect additional data including the amount of language arts instruction received, mode of instruction, and characteristics of the teacher's questioning strategy. Guidelines are included for recording each of the twelve variables observed: place of instruction, activities during no instruction, basic skills instruction, instruction other than basic skills, adult contact and group size during basic skills instruction, time spend on- and off-task, teachers' use of verbal and nonverbal signal systems, language of instruction, mode and content of instruction, and types of instructional questions used by the teacher. Appendices contain the PAR-R observation form, interrater reliability correlations, and a sample computer printout giving time spent on classroom activities by students observed in Title I, Non-Title I, Title I Migrant, and LESA (Limited English Speaking Ability) programs.
