- Twelve primary teacher were observed by trained observers during their assignment and supervision of students' seatwork tasks for a minimum of seven scheduled reading periods. Data were collected during each observation by recording what the teacher did in assigning seatwork and what the students did in completing the assignment. Observation data for each teacher were summarized over the seven observations. Teachers' behaviors were then compared to recent recommendations found in the teacher effectiveness and directinstruction literature. The results indicated that teachers failed to follow the majority of recommendations found in the literature and did not assume a central role in students' learning. The use of modeling, guided practice and feedback were lacking in these teachers' assignment and supervision of students' reading seatwork. 1986 Taylor & Francis Group, LLC.
