The results of an earlier experimental study of the effectiveness of a set of principles for small group instruction in first grade reading groups called for a revision of the list of principles. Revised principles were written for (1) group organization (seating, transitions, starting the lesson); (2) the introduction of lessons and activities (overviews, new words, and work assignments); (3) student participation (asking questions, taking turns, calling on students, and monitoring individuals); (4) teacher questions and student answers (academic focus, word attack questions, waiting for answers, giving needed help, offering explanations); (5) correct student reponses (acknowledging correct answers, explaining the answer when necessary, and follow-up questions); and (6) praise and criticism (praise in moderation, correction rather than criticism, and specificity in praise).
