This literature review focuses on the effects of class size on styles of teaching practice, and on pupil behavior and attainment. Most of the literature is from the United States. Evidence from previous reviews, correlational studies, meta-analyses, and experimental interventions are presented in this document. Much of the existing evidence is at…

Estimated the impact of class size on instructional practices and the use of time in high school mathematics and science courses using data from the National Education Longitudinal Study. Findings reveal that class size has an impact on the use of class time, both instructional and noninstructional. (SLD)

Interviews with teachers of 17 small first-grade classes at 10 Edmonton (Alberta) schools found that teachers drew on the contextual benefits of small classes to support students' skill development in a creative and integrated curriculum. Teachers used individualization; active learning; integration of reading, writing, and speaking; and a variety…

ClassWide Peer Tutoring (CWPT) is an evidence-based instructional strategy effective with students with and without disabilities. The evidence for efficacy is strong with respect to students in elementary schools learning basic academic skills in classrooms with large teacher-pupil ratios, and relatively less strong for students in secondary…

Using a pretest-posttest comparison-group design, this 16-week study investigated the effects of 2 instructional approaches on the phonological awareness, alphabetic knowledge, and early reading of kindergarten children. The primary goal was to compare a form of contextualized instruction based on an adapted interactive writing program with a…

Given the failure of previous research to find consistent effects of class size on students' achievement, this study examined whether teachers in British elementary schools changed their behavior in ways conducive to learning when they worked with classes significantly smaller than average. Seven pairs of elementary school teachers judged as…

Reducing class size is an important step in promoting effective learning, but reducing a class from 35 to 15 students alone will not produce the desired results if faculty do not alter their teaching styles. Students must be empowered through teaching techniques that utilize writing, recitation, reaction papers, case studies, peer group pressure,…

Examines second and third grade data from Project STAR, a reduced class size study. Observers viewed teachers, some of whom received inservice training on effective teaching and class type. Observers' narratives and ratings of class activities and interaction indicated little change in teaching practices regardless of class type or training. (SM)

A survey examined the perceptions of 404 mothers on the availability and importance of various resources for their children (ages 4-17) with Asperger syndrome or nonverbal learning disorder. A significant number (20-30%) reported that pragmatics training, social skills training, smaller classes, or a trained aide were not made available. (Contains…

It is widely assumed that increasing the number of teaching assistants (TAs) in the classroom will be beneficial to children, and this is one important aim of the recently implemented Workforce Agreement. But there are still significant gaps in knowledge about many aspects of their deployment and impact. The Class Size and Pupil-Adult Ratios…

Although experimental results indicate that smaller classes promote higher achievement in early elementary school, the broader literature on class-size effects is inconclusive. This seeming contradiction raises questions about the generalizability of experimental evidence, an issue that this article addresses by examining the effects of class size…

Innovations which were incorporated into large, introductory, educational psychology lecture classes are described and compared to smaller classes that did not make use of the innovations. Four innovative pedagogical techniques are used: (1) a mastery approach, (2) formative evaluation, (3) a modified pyramid-like structure using small group…

The comparative effects of large and traditional-sized remedial mathematics classes on college student aptitude and attitude were studied. Two large pre-algebra classes of 129 and 121 students and traditional-sized classes ranging in size from 30 to 40 students were assessed by informal observations and two instruments: a department-developed…

This practitioner brief focuses on the question: What happens when beginner-level English-as-a-Second-Language (ESL) students work in small groups? This question was pursued because the ESL teacher wanted to make use of small self-directed groups during class time. She found that the students needed a lot of structure from the teacher to make…
