This study examined the effects of teacher aides on students' academic achievement, addressing: whether the presence of a full-time aide in K-3 classrooms would affect student achievement; whether the presence of an aide in the primary grades would affect students' later academic achievement (grades 4, 6, and 8); and whether the nature of aide…

Small classes in grades K-3 boost student academic performance in all subjects and in prosocial behavior. Results are both short- and long-term. One study explored the theory that a major cause behind improved academic achievement involves improved student behavior, which increases student engagement in the classroom. Two other studies provide…

The education reform movement has fostered renewed interest in class size. Tennessee and Indiana experiments with smaller class size in primary grades have yielded improved student behavior and achievement scores. Tennessee's new Student-Teacher Achievement Ratio Project (STAR) is a longitudinal study furthering research on small class benefits.…

The Lasting Benefits Study is following up the effects of small class size on the achievement of elementary school students in Tennessee's Student/Teacher Achievement Ratio Project (Project STAR). Results show improved achievement for participants in small classes up through grade 3 that last at least through grades 4 and 5. (SLD)

Landmark studies in the late 1970s and 1980s, including Tennessee's Project STAR (Student Teacher Achievement Ratio), raised the nation's awareness that reduced class size does have a positive impact on students' academic achievement. This report provides a sketch of class-size reduction's history in a prefatory overview. Chapter 1 describes…

Class size in elementary grades has taken on added importance recently. Research on the topic is finally getting some attention. Legislative and administrative actions to reduce deficits are pushing for larger class sizes, in addition to eliminating nonessential curricular activities, such as music, drama, and art. In Florida, various institutions…

Most research on the positive effects of class-size reduction (CSR) has occurred in the elementary level (Word, Johnston, Bain, Fulton, Zaharias, Lintz, Achilles, Folger, & Breda, 1990; Molnar, Smith, Zahorik, Palmer, Halbach, & Ehrle, 1999). Is CSR an important variable in improving education in the middle grades? Can small classes be…

This paper summarizes class size research conducted primarily since 1970. The paper discusses various relevant issues for use in policy, in schools, and in additional research. Several studies over the years have focused on: the issue of small being better and less being more and emphasized the STAR (Student Teacher Achievement Ratio) education…

Beginning in 1991-92, a local school district undertook a concerted effort to reduce class size in grades 1 through 3 to 1:15, the Student/Teacher Achievement Ratio (STAR) Project. Achievement gains and research indicated that class size caused increased achievement and facilitated improved instruction. (SLD)

Using research to develop a solid educational foundation can accommodate diverse forces confronting educators, initiate systemic change, and help solve the pupil-teacher ratio (PTR)/class-size puzzle. Small K-3 classes are effective and can be efficient if changes are research-based and exploit class-size and PTR differences. (25 references) (MLH)

This testimonial presents evidence that reduced class size (CSR) has positive effects on student learning in grades K-3. Student achievement is improved in the areas of academics, behavior and discipline, citizenship and participation in and outside school, and development into competent and productive adults. The paper emphasizes that class size…

Confusion over the concepts of class size and pupil-teacher ratio (PTR) creates a conundrum for researchers, policy makers, and practitioners. An examination of how these two concepts are different is presented in this paper. A review of the literature suggests that class-size reduction makes a positive overall difference in student achievement,…

Summarizes a major longitudinal study (Project STAR) conducted in Tennessee between 1985 and 1989, provides some results updating STAR findings through 1992, and suggests research-based courses of action. Class-size research in primary grades is showing the efficacy of small classes of 1:15. Application of early experimental results in 17 poor…

Discussion and research concerning class size can be traced back at least to the 12th century. An overview of recent research on the subject is provided in this report. The paper, which serves as an introduction to a symposium on class size, examines research that has appeared in the past 20 years, but it concentrates on the results of a…

This paper presents findings of a study that examined the relationship between the performance (as measured by test results) of pupils in classrooms with full-time teacher aides. The Student Teacher Achievement Ratio project (STAR) was implemented in Tennessee from 1985 through 1989 to study the effects of class size on student achievement and…
