Small classes in the elementary grades have been shown to boost students’ academic performance. However, researchers continue to seek a consistent, integrated explanation of “why” small classes have positive effects. This article forwards the hypothesis that when class sizes are reduced, major changes occur in students’ engagement in the classroom. Engagement is composed of “learning behavior” and pro- and antisocial behavior. Both are highly related to academic performance. We first review research on the relationship between class size and student engagement. Second, we review sociological and psychological theory about the behavior of individuals in groups to explain how student behavior can be affected by changes in class size. Both theory and empirical findings support our hypothesis, although additional research is required. High-priority questions needing further research are identified in the conclusion.
After years of debate, speculation, and research, Tennessee's Project STAR produced clear answers to the question, “Do small classes result in improved academic achievement in the elementary grades?” This article describes the features that made STAR unique and summarizes the findings with regard to pupil performance and behavior. New analyses show the magnitudes of the “small-class advantage” during and after the 4-year experimental period. The positive findings of STAR have been greeted with enthusiasm by the education community and are providing impetus for class size reduction (CSR) efforts in many districts. At the same time, some detractors continue to oppose the idea. Although they usually do not take issue with the strength of the STAR design, they disagree that the findings warrant CSR initiatives in most cases. This article examines those arguments critically. Finally recommendations are offered for policymakers, education practitioners, and researchers for using the information learned to date about the relationship of class size with students' academic achievement.
The purpose of this investigation was to extend our knowledge of the effects of small classes in the primary grades on pupils’ academic achievement. Three questions were addressed that have not been answered in previous research: (1) How large are the effects of small classes relative to the number of years students participate in those classes? (2) How much does any participation in small classes in K–3 affect performance in later grades when all classes are full-size? (3) How much does the duration of participation in small classes in K–3 affect the magnitude of the benefits in later grades (4, 6, and 8)? Rationales for expecting the continuing impacts of small classes were derived in the context of other educational interventions (for example, Head Start, Perry Preschool Project). The questions were answered using data from Tennessee's Project STAR, a statewide controlled experiment in which pupils were assigned at random to small classes, full-size classes, or classes with a full-time teaching assistant. Hierarchical linear models (HLMs) were employed because of the multilevel nature of the data; the magnitude of the small-class effect was expressed on several scales including “months of schooling.” The results for question (1) indicate that both the year in which a student first enters a small class and the number of years (s)he participates in a small class are important mediators of the benefits gained. The results for questions (2) and (3) indicate that starting early and continuing in small classes for at least three years are necessary to assure long-term carryover effects. Few immediate effects of participation in a class with a full-time teacher aide, and no long-term benefits, were found. The results are discussed in terms of implications for class-size reduction initiatives and further research questions.
A large-scale experiment is described in which kindergarten students and teachers were randomly assigned to small and large classes within each participating school. Students remained in these classes for 2 years. At the end of each grade they were measured in reading and mathematics by standardized and curriculum-based tests. The results are definitive: (a) a significant benefit accrues to students in reduced-size classes in both subject areas and (b) there is evidence that minority students in particular benefit from the smaller class environment, especially when curriculum-based tests are used as the learning criteria. A longitudinal analysis of a portion of the sample indicated that students in small classes outperform their peers in kindergarten classes of regular size and also gain more in reading outcomes during the second year. The question of why these effects are realized remains largely unanswered, but in light of these findings, is particularly important to pursue.

Despite more than 600,000 teacher aides in American schools today, research provides little information about their classroom activities, their qualifications for carrying out their duties, or their impact on student achievement and behavior. This investigation asked whether the presence of a teacher aide in the classroom has any noticeable impact on pupils' learning. Three primary questions were addressed: (1) In Grades K through 3, does the presence of a full-time teacher aide in the classroom affect students' academic achievement? (2) If teacher aides have a positive effect on students' performance, does the effect depend on the number of years the student attends classes with a teacher aide? (3) Do some functions of aides (i.e., clerical tasks, instructional tasks, noninstructional tasks) have a greater impact on student achievement than others? This investigation showed that the teacher aide movement in the United States has created a state of affairs that requires many aides to perform tasks for which they are ill-prepared. In addition, teacher aide data were analyzed from Tennessee's Project STAR, a longitudinal experiment in which students were assigned at random to small classes, regular-size classes without an aide, or regular-size classes with a full-time teacher aide. The analyses reported here extend previous investigations, examining the functions and effects of teacher aides in depth. The results showed that teacher aides have little, if any, positive effect on students' academic achievement. The only positive effect was an improvement in reading scores for students who attended a class with a teacher aide for 2 or 3 years. These results were the only exceptions to a plethora of negative findings. The study also showed that the types of duties aides performed had no bearing on student achievement. Because teacher aides are called upon increasingly to provide instruction to pupils, policies and research must help us select and prepare aides to perform effectively.
