Separating students into homogeneous groups is a common instructional practice used by elementary teachers during reading instruction. Although researchers have been studying the effects of homogeneous grouping for many decades, there is little consensus on whether grouping is an effective or equitable instructional practice. The central challenge…

This explanatory sequential quasi-experimental study investigated the impact of differentiated instruction on reading comprehension attainment in mixed-ability classrooms. Fifty-four tenth grade students from two classes in two different schools took part in the study. They were randomly distributed into an experimental group (n = 27) and control…

Among comprehension instructions that encourage collaborative learning, Collaborative Strategic Reading (CSR) and Questioning the Author (QtA) were known for their effectiveness. Both help students on improved comprehension of text and building a positive relationship among themselves. Similarly, Ability Grouping and Self-efficacy were factors…

Gifted education programs are diverse with respect to their structure and foci. This diversity is reflective of the field itself. With this large, multi-state study, we surveyed practices employed in elementary schools (N = 1,548). Differences were observed in the implementation mechanics of English and mathematics curriculum. Interrelationships…

Defining causal effects as comparisons between marginal population means, this article introduces marginal mean weighting through stratification (MMW-S) to adjust for selection bias in multilevel educational data. The article formally shows the inherent connections among the MMW-S method, propensity score stratification, and…

The purpose of this study was to investigate the effects of homogeneous versus heterogeneous reading-style grouping on EFL students' non-preferred reading style and reading comprehension. The study used a pretest-posttest experimental design. The original subjects of the study (N=86) were Egyptian English major senior students during the 2005/2006…

A kindergartner's opportunities to develop reading and language arts skills are constrained by the amount of time allocated to reading instruction. In the meantime, the student's engagement in learning tasks may increase if the instruction has been adapted to his or her prior ability through homogeneous grouping. This study investigates whether…

This article investigates the practice of heterogeneous grouping for reading and literacy instruction through a detailed interactional analysis focused on the least proficient readers in two mixed-ability group contexts. The resulting analysis suggests that struggling readers in heterogeneous groups may encounter the same problems often associated…

Implementing a qualitative case study, the researcher explored how a sixth-grade English language learner participated in literature discussions of various groupings in a classroom setting, and how she perceived these interactions about reading and text in the process of learning to read. The participant was struggling with reading in a…

Success for All (SFA)[R] is a whole-school reform model that includes a reading, writing, and oral language development program for students in prekindergarten through eighth grade. Classroom reading instruction is delivered in daily 90-minute blocks to students grouped by reading ability. Immediate intervention with tutors who are certified…

A survey conducted among approximately 1,400 students at 63 primary schools showed that learning gains for initial reading varied significantly for students in the last 6 months of Year 3. Learning gains turned out to be much higher in classes where students had received explicit or direct instruction, where instruction had been organized…

Examines the literature concerning the positive and negative effects of ability grouping, reporting on eighteen reading research studies. (RB)

Twenty-one studies of the effectiveness of various grouping plans for elementary reading instruction are reviewed in this paper. Following the review, the studies are summarized according to the grade level with which they dealt, and conclusions are drawn regarding the most effective grouping plans. Among the conclusions reported are: (1) no one…

Suggests practical ways for grouping students for reading instruction. (VJ)

The attitudes, feelings, and self-concept of 30 sixth-grade children from high reading groups and 30 from low reading groups as related to ability grouping in the teaching of reading were examined in this study. The Piers-Harris Children's Self Concept Scale, the San Diego County Inventory of Reading Attitude, and an interview schedule developed…
