Designed to study individual use of time spent in reading during regularly scheduled language arts instruction in a natural classroom setting, this coding sheet consists of nine categories: (1) engagement, (2) area of language arts, (3) instructional setting, (4) partner (teacher or pupil(s)), (5) source of content, (6) type of unit, (7) assigned or chosen task, (8) rate of success, and (9) other activities. Students are observed for 30-second intervals on a rotation basis, and the behavior noted is coded in the appropriate column on the coding sheet. Validity, reliability, and normative data are included. (This document is one of those reviewed in The Research Instruments Project (TRIP) monograph "Measures for Research and Evaluation in the English Language Arts, Volume 2," published by the Committee on Research of the National Council of Teachers of English in cooperation with the ERIC Clearinghouse on Reading and Communication Skills. The TRIP review, included here as an introduction to the instrument, describes the instrument's category (language arts), title, author, date, age range (applicable to any instructional situation), purpose, and characteristics.)
