The effects of group composition on achievement,interaction, and learning efficiency during computer-based cooperative instruction

This study investigated the effects of cooperative group composition, student ability, and learning accountability on achievement, interaction, and instructional efficiency during computer-based instruction. A total of 125 sixth- and seventh-grade students were randomly assigned to heterogeneous or homogeneous dyads. Groups were designated as having either group or individual account-ability for mastery of lesson content. Cooperative dyads completed a tutorial on a novel symbolic mathematics topic, featuring basic symbol learning and application of the symbols. Indicators of ongoing cooperation were collected during instruction. Five days later, students completed a posttest. Low-ability students interacted more and completed the instruction more efficiently in heterogeneous than in homogeneous groups. High-ability students completed the instruction more efficiently in homogeneous than in heterogeneous groups. Cooperation was significantly related to achievement for heterogeneous ability groups, but not for either homogeneous high- or low-ability students.     

The effect of grouping of laboratory students on selected educational outcomes

The purpose of this study was to discover if grouping students in the laboratory on the basis of their formal reasoning ability affected (1) their science content achievement, (2) their formal reasoning ability, (3) the learning environment in the laboratory, and (4) the relationships between individuals in a particular group. The laboratory groups for three physical science classes for preservice elementary teachers were arranged as follows: (1) one class with students of unequal reasoning ability grouped together, i.e., one highly developed formal reasoner per group (the heterogeneous group), (2) one class with students of similar reasoning ability grouped together (the homogeneous group), and (3) one class arranged in groups according to the desires of the class members (the student choice group). The three classes were compared using pre-and post-scores on content and formal reasoning instruments and scores for classroom environment and social relationships. Results indicated that the groupings as described had significantly different effects on science content achievement but not on any of the other questions posed above. The students in the class with laboratory teams grouped by student choice had significantly lower science content scores than the students in the classes with teams formed using either the heterogeneous or homogeneous grouping procedures. The difference between the heterogeneously and homogeneously grouped classes was not significant at the 0.05 level.     

The Effects of Ability Grouping upon Achievement in Eleventh Grade American History

The basic assumption which nurtures the controversial practice of homogeneous ability grouping is that grouping students by some measure of ability reduces the range of learning differences, when compared with heterogeneous (random) grouping, and this narrowing of range aids the teaching and learning process. To test this assumption two cooperating high schools, one homogenously grouped and the other heterogeneously grouped, provided 120 matched pairs of Ss. The basic assumption was not upheld; heterogeneous students showed significantly greater achievement gain in 11th grade American history (q > .05), at all four levels of ability.     

Aptitude treatment effects of laboratory grouping method for students of differing reasoning ability

This study examines aptitude treatment effects in an inquiry/learning cycle based physical science class for elementary education majors. The aptitude was formal reasoning ability and the students were arranged into three groups: high, middle, and low ability reasoners. The treatment was method of forming groups to work in the laboratory. Students in each of three classes were grouped according to reasoning ability. In one class the laboratory groups were homogeneous, i.e., students of similar reasoning ability were grouped together. In the second class the students were grouped heterogeneously, i.e., students of different reasoning ability were grouped together. In the third class, the student choice pattern, the students chose their own partners. The findings were that there were no aptitude treatment interaction for achievement or for gain in formal reasoning ability, that grouping students of similar cognitive ability together for laboratory work in the class was more effective in terms of science achievement than grouping students of differing cognitive ability together or than allowing students to choose their own partners, and that students at different levels of reasoning ability experienced differential gains in that ability over the semester.     

Exploring the influence of homogeneous versus heterogeneous grouping on students’ text-based discussions and comprehension

Small-group, text-based discussions are a prominent and effective instructional practice, but the literature on the effects of different group composition methods (i.e., homogeneous vs. heterogeneous ability grouping) has been inconclusive with few direct comparisons of the two grouping methods. A yearlong classroom-based intervention was conducted to examine the ways in which group composition influenced students’ discourse and comprehension. Fourth- and fifth-grade students (N = 62) were randomly assigned to either a homogeneous or heterogeneous ability small-group discussion. All students engaged in Quality Talk, a theoretically- and empirically-supported intervention using small-group discussion to promote high-level comprehension. Multilevel modeling revealed that, on average, students displayed positive, statistically and practically significant gains in both basic and high-level comprehension performance over the course of Quality Talk. Further, our findings indicated heterogeneous ability grouping was more beneficial than homogeneous ability grouping for high-level comprehension, on average, with low-ability students struggling more in homogeneous grouping. With respect to student discourse, additional quantitative and qualitative analyses revealed group composition differences in terms of the frequency, duration, and quality of student questions and responses, as well as the types of discourse low-ability students enacted in homogeneous groups. This study expands upon the extant literature and informs future research and practice on group composition methods.

The Effects of Within-Class Ability Grouping on Academic Achievement in Early Elementary Years

Abstract

By incorporating two theoretical frameworks this study examines how school characteristics shape first-grade reading ability-grouping practices, and how this, in turn, affects students’ reading achievement. The author uses the data from the Early Childhood Longitudinal Study and applies the propensity-score method to examine whether first-grade ability grouping improves student achievement, whether ability grouping increases achievement inequalities, and whether its effects vary by student initial abilities and/or school contexts. Findings support an argument that ability grouping is an organizational response to problems of diversity in the student body. Schools that use ability grouping are likely to have heterogeneous ability compositions. They are also public, low-performing, low socioeconomic status, and high-minority schools. In these schools, ability grouping has no effects or negative effects, particularly for low-ability students. In contrast, ability grouping may improve achievement for all students in schools with advantageous characteristics, mostly private schools, and may reduce achievement inequalities, because low-ability students benefit the most from this practice.     

Small-group composition and peer effects

This paper reviews research on grouping of students within classes and its effects on learning. Primary consideration is given to grouping and mixing students by ability, though consideration is also given to grouping and mixing students by ethnicity and gender as well as to research on the effects of group size. Results of meta-analyses of grouping show a small but meaningful advantage of forming students into groups for instruction as compared to using whole-class instruction. In teacher-led, homogeneous ability groups, peer effects result from the normative environment to the extent that peers contribute to norms for behavior, constructed through cycles of reciprocal teacher–student interaction. In peer-led, heterogeneous ability groups, peer effects stem directly from group interactions and discourse among students that lead to cognitive restructuring, cognitive rehearsal, problem solving, and other forms of higher-level thinking. Similarly, in groups of different ethnic and gender composition, peer effects stem from interactions among students according to their perceived status and relative influence within the groups. We argue that these peer influences interact with instructional processes to mediate the effects of group composition on students’ learning.     

Public schools,private schools,and the common school ideal

According to the ethos of the nineteenth century common school, all students are assigned the same tasks, and in all the same powers developed. Twentieth century innovations such as ability grouping are foreign to the common school's egalitarian ideal. Such innovations may reinforce connections between students' ascribed background characteristics and school achievement. Proponents of the common school sought to sever these connections. Coleman, Hoffer, and Kilgore, inHigh School Achievement (1982), argue that private schools are more in keeping with the common school tradition than public schools. In their view, private schools offer greater meritocratic justice than public schools; this is due to the fact that private schools minimize the impact of students' background characteristics, such as race and family income, on achievement. Our findings, however, are inconsistent with those of Coleman et al. We use a data set provided by the Educational Testing Service in which public and private subgroups are approximately equal with respect to measured background factors, and we employ a more adequate complement of independent variables, along with outcome measures which appear to be more curriculum sensitive than those employed by Coleman et al. Our regression results indicate that private secondary schools are no more effective than public schools at severing the connections between background characteristics and measured achievement in English, math, and American history.     

The effects of cued interaction and ability grouping during cooperative computer-based science instruction

The purpose of this study was to investigate the effects of verbal interaction cues and ability grouping within a cooperative learning computer-based program. We blocked 231 eighth graders in a required science class by ability and randomly assigned them to homogeneous lower-ability, homogeneous higher-ability, or heterogeneous mixed-ability dyads. Each dyad was randomly assigned to a computer program that either did or did not contain verbal interaction cues designed to facilitate summarizing and explaining between partners. Results indicated that students using the cued version of the program performed significantly better on the posttest than students using the noncued version. Direct observation of student interaction indicated that students in cued dyads exhibited significantly more summarizing and helping behaviors than noncued students. Furthermore, higher-ability dyads exhibited significantly less off-task behavior than the other dyads. Implications for designing computer-based instruction for cooperative settings are provided.     

Academic Outcomes of Ability Grouping Among Junior High School Students in Hong Kong

Abstract

Ability grouping is supposedly undesirable because it leads to deficits in academic self-concept and academic achievement. However, it appears to be justifiable for its improvement of teaching and learning in schools, perhaps more so in a collectivist culture. In view of the paucity of data examining the controversy in Hong Kong, the authors collected data from 2,720 junior high school students with a random sampling procedure and obtained teachers' reports about the students' subsequent academic achievement, ability grouping, and the ability level of the class. The authors maintained students' past academic achievement as a control variable in predicting their subsequent academic achievement and self-concepts. Results revealed no significant detrimental effect caused by the ability-grouped class and the ability level of the ability-grouped class. Rather, students in classes that were more homogeneous according to past academic achievement tended to have significantly higher subsequent academic achievement and self-esteem. Results revealed no variation attributable to each student's gender and IQ in the effects of ability grouping.     

Effects of cooperative incentives and heterogeneous arrangement on achievement and interaction of cooperative learning groups in a college life science course

The purpose of this study was to examine the importance of cooperative incentives and heterogeneous grouping as elements of cooperative learning in a college life science course. Cooperative learning may be defined as a classroom learning environment in which students work together in heterogeneous groups toward completion of some task. Cooperative incentive structures provide some type of group reward based on group products or individual learning. In heterogeneous grouping, students are arranged in order to maximize variety within groups. A 2 × 2 design was utilized in this study. The independent variables considered included (a) use of cooperative incentives in learning groups, and (b) use of heterogeneous grouping in cooperative learning groups. Dependent variables for all treatment groups were scores from a multiple-choice instrument developed for an earlier, related study, along with direct observational data on frequency of cooperative interactions. Analysis of covariance (ANCOVA) was used as the data analysis procedure for the achievement portion of the study, and analysis of variance (ANOVA) was used for analysis of the cooperative interaction portion of the study. No significant differences were found between the treatment groups.     

Academic self-concepts in adolescence: Relations with achievement and ability grouping in schools

The effects of ability grouping in schools on students' self-concept were examined in a sample of 23 secondary schools with a range of structured ability groupings. Measures of general self-concept, academic self-concept, and achievement were collected from over 1600 students aged 14–15 years and again two years later. Students' academic self-concept, but not their general self-concept, was related to the extent of ability grouping in the school attended. Subject-specific facets of academic self-concept were not related to the number of years of ability grouping students had experienced in English, mathematics and science; however, they were related to students' position in the grouping hierarchy, with students in high-ability groups having significantly higher self-concepts in all three subjects than students in low-ability groups. Students' intentions to learn in future were more strongly affected by self-concept than by achievement.     

Research Implications for Difficult to Teach Students

The relationship of academic learning time to student achievement has been demonstrated, but primarily with mainstream students. Brophy presents arguments that generalize these findings to special populations. Although it appears that academic learning time and active engagement may have similar effects on achievement for all students, the ability of teachers to successfully implement these instructional strategies for students with special needs within current administrative arrangements is questioned. The manner in which teachers allocate their resources and the problems created by attempting to teach large groups of students with heterogeneous needs is discussed.     

Behavior of College Students under an Unlimited Cut System

The effects of six classroom motivational treatments on 112 fifth and sixth grade students were measured using a difference score on a substitution task. Individual goal setting and competitive treatments, under reward and non-reward conditions, are analyzed by means of planned comparisons. Results indicate a significant interaction which suggests caution against an oversimplified interpretation of main effects. A S’s performance in a competitive treatment is shown to be dependent upon three factors: his initial ability relative to that of his classmates; the presence or absence of a reward; the homogeneous or heterogeneous nature of the group in competition. The evaluation of this significant 3-way interaction ( i. e., ability x reward x grouping) and comparisons of means suggest several tentative hypotheses and raise highly relevant questions regarding the use of classroom motivational techniques which are competitive in nature.     

The effects of cooperative learning and learner control on high- and average-ability students

The effects of studying alone or in cooperative learning groups on high- and average-ability students were investigated. Also examined were the effects of completing computer-based instruction using either a learner- or program-control version of a lesson. A total of 175 fourth-grade students were classified as being of high or average ability and randomly assigned to paired or individual treatments stratified by ability. Students completed training to enhance small-group interaction before completing a computer-based tutorial and a posttest. Following cooperative learning, students demonstrated increased achievement and efficiency as well as better attitudes toward both the computer lesson and grouping. Students completed more practice items and examples in program-control treatments than in learner-control treatments. However, the form of lesson control did not affect students' achievement or attitudes.     

Gender,ethnicity, science achievement,and attitudes

Science achievement and attitudes were assessed for a series of students in Grades 3–12 representing the four major ethnic groups in Hawai'i (USA). It was found that more differences were accounted for by ethnicity and even grade than by gender; in addition, there was little interaction between ethnicity and gender. With respect to ethnicity, Caucasian and Japanese-American students outscored Hawaiians and Filipino Americans at all grade levels. Caucasians also expressed the most positive attitudes toward science and Japanese expressed the most positive perceptions of scientists; Hawaiians generally expressed the least positive perceptions. Younger students generally expressed more positive attitudes toward science but less positive perceptions of scientists compared to older students. Caucasians expressed the most positive perceptions of their own science ability and achievement. With respect to gender, there were no consistent differences in science achievement and very few in science attitudes and perceptions. The major differences were that males reported more experiences with physical science activities and also expressed a more male-stereotyped view of science than females, with some variation by ethnicity and grade. There were differences in enrollment in advanced science and mathematics classes in that females were more likely than males to enroll in many, but for both genders the major reason was college admission: Japanese students were most likely and Hawaiians least likely to indicate science interest as a reason. Findings are discussed within the context of cultural ecology and feminist social theory. © 1996 John Wiley & Sons, Inc.     

Design of technology-based information-referenced grouping systems for use in large urban schools

There are many subtle but extremely important differences between grouping students and tracking students for purposes of designing appropriate instructional interventions. Unfortunately, in many inner-city urban settings, the policy of grouping students eventually becomes a policy ofde facto tracking of students. While grouping students seems to be an educationally justifiable policy in many school situations, tracking students raises serious concerns with regard to its educational value, social desirability, and complicity with the legal notions of due process and equal protection. This study examines the use of a specific form ofshort-term grouping of students that is based on an information-referenced criterion for selection. Using a large sample of ninth- and eleventh-grade students, an information-referenced grouping procedure was designed for the areas of language arts and mathematics. The study finds that grouping selections, using an information-referenced criterion, are strongly associated with teachers perceptions of these students' actual educational and information needs. In addition, the information-referenced grouping design provides important specific educational feedback to both students and teachers to help low-attaining students move to mainstream classes. Finally, many of the due process concerns raised by educational researchers with regard to abuses and shortcomings of presently used ability or standardized test-driven grouping efforts are addressed.     

Relationship between ability-paired interactions and the development of fifth graders' concepts of balance

This study describes the effects of ability-paired student interactions on achievement as fifth graders (10-year-olds) worked on laboratory activities relating to balance. Achievement gains were assessed (n = 83) by analysis of pretest–posttest differences on the lever concept test. Audio recordings and field notes (n = 30) were analyzed for the following laboratory behaviors: number of words spoken, tinkering, block moving, turns speaking, incidence of helping and distracting behavior. Results revealed that: (1) low-ability student achievement is greater when students are paired with high-ability partners; (2) low-ability students speak more words, exhibit less distracting behavior, and move blocks on the lever less when they are paired with a partner of high ability; (3) high-ability students speak more words, take more turns speaking, and exhibit more helping behaviors when they are paired with low-ability students rather than with other high ability students; and (4) there are no achievement differences for high-ability students regardless of the ability level of their partner. These findings suggest that heterogeneous grouping of students in science can be beneficial to low-ability students partnered with high-ability students, without being detrimental to the high-ability partners.     

Effects of collaborative group composition and inquiry instruction on reasoning gains and achievement in undergraduate biology

This study compared the effectiveness of collaborative group composition and instructional method on reasoning gains and achievement in college biology. Based on initial student reasoning ability (i.e., low, medium, or high), students were assigned to either homogeneous or heterogeneous collaborative groups within either inquiry or didactic instruction. Achievement and reasoning gains were assessed at the end of the semester. Inquiry instruction, as a whole, led to significantly greater gains in reasoning ability and achievement. Inquiry instruction also led to greater confidence and more positive attitudes toward collaboration. Low-reasoning students made significantly greater reasoning gains within inquiry instruction when grouped with other low reasoners than when grouped with either medium or high reasoners. Results are consistent with equilibration theory, supporting the idea that students benefit from the opportunity for self-regulation without the guidance or direction of a more capable peer.
