Designed to assist the observer in the understanding of the Group Reading Interaction Pattern Observation Instrument (GRIP) training manual, this programmed review contains a series of coding activities provided for the purpose of determining if each observer can differentiate between the categories and subcategories of the instrument as well as understand how behaviors are coded using the instrument. Coding exercises are provided for the following categories: (1) the activity/material grid; (2) context; (3) time and context; (4) sets purpose; (5) vocabulary; (6) engagement; (7) past learning; (8) introduction of lesson; (9) question and answering; and (10) feedback, command, social comments, and practice/application. Appendixes include answers to the scripts as well as blank interaction charts. An abridged version of the programmed review is also included. (HOD)
