Phases and patterns of group development in virtual learning teams

With the advancement of Internet communication technologies, distributed work groups have great potential for remote collaboration and use of collective knowledge. Adopting the Complex Adaptive System (CAS) perspective (McGrath, Arrow, & Berdhal, Personal Soc Psychol Rev 4 (2000) 95), which views virtual learning teams as an adaptive and self-organizing entity, this study examined group development processes of seven intact virtual learning teams over 12 weeks using the multiple case study design. Content analysis revealed seven temporal group development phases: orientation, scheduling, exploration, work and decision, progress check and evaluation, refinement and formatting, and termination. The development pattern of each virtual learning team could be described as either Linear Progression, a straight movement through those phases, or Adaptive Progression, a backward movement to a previous phase for adaptation before proceeding. We also identify the factors that caused each team to develop in one way or the other and conclude with the implications of conceptualizing virtual teams as a CAS.     

Peer teaching and higher level cognitive learning outcomes in problem-based learning

Law education at the University of Limburg (Maastricht, The Netherlands) features small-group tutorials alternating with periods of independent study. Every group of 10 students was tutored by a staff member or an undergraduate student from the third or fourth year. Students guided by a staff member scored significantly higher on a test designed to measure higher order cognitive skills than students guided by a student tutor. Student tutors were rated no differently from staff tutors with respect to the way they stimulated learning processes, directed the discussion content and monitored the discussion process. It seems that in a quantitative way, staff tutors and student tutors behave more or less the same. Qualitatively, however, there may be differences in their behavior which the tutor functioning questionnaire is unable to tap. Interventions of staff tutors may be more to the point than those of student tutors due to the fact that they are experts in their fields.     

Peer group interaction of physically abused children

The aim of this research study was to test the assumption that physically abused children differ significantly from their non-abused peers along dimensions which characterize abusing adults and other social deviants. Nineteen 5-10 year-old physically abused children and 38 non-abused peers were assessed by video-taped behavioral observations during free-flowing social interaction in a playroom. The dimensions tapped were: aggression, warmth, fear, pleasure, concentration, imagination and social participation. The dimension social participation was split into three variables: total social participation, negative participation and positive participation. The data from these nine dimensions was subject to a Pearson's correlation. Given the high correlation amongst these variables the data was subject to a principal components analysis with varimax rotation. From this analysis two components emerged which explained 76.9% of the total variance. These components were designated "social interaction" (component 1) and "hostility" (component 2) and were then subject to analyses of variance. A significant difference was found between the two groups on the "social interaction" component. The implications of these findings were explored and treatment possibilities examined.     

Peer collaboration and discourse patterns in learning from incompatible information

This study investigated the effects of peer collaboration anddiscourse patterns on conceptual change in the context of high-schoolstudents learning from incompatible scientific information. The domainof investigation was biological evolution. Participants included 108students from Grades 9 and 12 randomly assigned to four conditions: (1)peer-conflict; (2) individual-conflict; (3) peer-assimilationand (4) individual-assimilation. Students were asked to think aloud ordiscuss with their peers eight statements consisting of scientificinformation ordered in ways that either maximized or minimized conflict.Several measures of prior knowledge and conceptual change were obtained.Peer collaboration resulted in some mixed findings suggesting that peereffects may vary depending on collaborative interactions. In-depthanalyses of collaborative interactions indicated two discourse patterns:surface moves included rating, ignoring, rejecting, and patching toeliminate differences; problem-centred moves involved problemrecognition, formulation of questions, and construction of explanations.Comparisons between successful and unsuccessful learners showedsignificant differences in their proportional use of surface andproblem-centred moves. External conflict did not lead to deeperdiscourse and more conceptual change; students may need toexperience meaningful conflict. These findings suggest why peercollaboration only works sometimes and indicate the importance ofhelping students to engage in productive discourse.     

Using student learning and development outcomes to evaluate a first-year undergraduate group video project

Students in an interdisciplinary undergraduate introductory course were required to complete a group video project focused on nutrition and healthy eating. A mixed-methods approach to data collection involved observing and rating video footage of group work sessions and individual and focus group interviews. These data were analyzed and used to evaluate the effectiveness of the assignment in light of two student learning outcomes and two student development outcomes at the University of Minnesota. Positive results support the continued inclusion of the project within the course, and recommend the assignment to other programs as a viable means of promoting both content learning and affective behavioral objectives.     

Peer group socialization of homophobic attitudes and behavior during adolescence

A social developmental framework was applied to test for the socialization of homophobic attitudes and behavior within adolescent peer groups (Grades 7-11; aged 12-17 years). Substantial similarity within and differences across groups were documented. Multilevel models identified a group socializing contextual effect, predicting homophobic attitudes and behavior of individuals within the group 8 months later, even after controlling for the predictive effect of individuals' own previously reported attitudes and behavior. Several group characteristics moderated the extent to which individuals' previously reported attitudes predicted later attitudes. Findings indicate the need to integrate the concurrent assessment of individual and social factors to inform the construction of more comprehensive models of how prejudiced attitudes and behaviors develop and are perpetuated.     

Peer assessment as a learning tool for enhancing student teachers' preparation

This study investigates how peer assessment contributes to enhancing student teachers' preparation during field experience. A semi-structured interview was conducted with 72 student teachers. The findings showed that the student teachers have positive beliefs about peer assessment. They think that it can be beneficial if some changes are made in the way it is employed in teacher education programs. In light of the study findings, the researchers put forth a number of suggestions and recommendations for employing peer assessment in teacher education programs in Jordan.     

Toward effective group formation in computer-supported collaborative learning

Group formation task as a starting point for computer-supported collaborative learning plays a key role in achieving pedagogical goals. Various approaches have been reported in the literature to address this problem, but none have offered an optimal solution. In this research, an online learning environment was modeled as a weighted undirected complete graph in which each learner was implied as a node and the relationship between them was denoted as a weighted arc. The weight of each link indicated the similarity degree between the corresponding individuals. The similarity between two students was measured as the mean of their absolute interest levels. The graph was also represented through a symmetric adjacency matrix. Then, a novel binary integer programming formulation was proposed to model the group formation problem and optimally assign each learner to the most appropriate group. The method was utilized to divide an online class of 32 learners into 8 groups of size 4. Findings indicated that the suggested model was successful in optimally solving the problem in 20.53 seconds, on average. The performance of the method was also compared with a modified version of K-means clustering algorithm. Although, the running time of the suggested technique was not as good as the clustering algorithm, it generated better outcomes in theory and in practice.     

Peer collaboration: accommodating students with mild learning and behavior problems

This study examined the effectiveness of a structured problem-solving process, peer collaboration, as a means of assisting classroom teachers in developing and implementing alternative interventions for students with mild learning and behavior problems. The study included 48 elementary and junior high school teachers in the intervention group and 43 elementary school teachers in a comparison group. Results indicate that teachers in the intervention group increased their tolerance for the range of students' cognitive abilities. These teachers reconceptualized their understandings of classroom problems and successfully implemented interventions for 86% of the 70 problems they attempted to solve.

Peer interaction and the learning of critical thinking skills in further education students

A teaching programme is reported in which criticalthinking skills (in the sense of reasonedjustification of arguments; see Kuhn, 1991, 1993) weretaught. The principal aims of the study were todevelop, implement and evaluate a programme forteaching evidence-based justification to vocationaleducation students in Further Education colleges. Teaching was via modelling and peer-based critiquingexercises in the context of the students' projectwork. Eighty-four Further Education college studentsunderwent a 10-session teaching intervention whichdovetailed with their Additional Assessmentintegrative project work. Students took part inpeer-based exercises in which they learned to critiqueimaginary examples of project outlines and plans,followed by similar peer-based critiquing of eachothers' proposed projects. Analysis of the students'dialogues with each other indicated that they hadlearned the importance of justifying arguments, andcontent analysis of their written work indicated thatthey engaged in justification of their arguments to asignificantly greater degree than control groups. Several key variables in the dialogues correlatedpositively with justification in the written work,suggesting that the dialogue had impacted on thewritten work. However, justification tended to be ofa weak kind (using anecdotes or experience-basedgeneralisations), and strong (i.e. formalresearch-based) evidence remained relativelyinfrequent and sometimes inappropriately used. Apsychometric test of general critical thinking skillsshowed no evidence of transfer of learning.     

Peer collaboration: the relation of regulatory behaviors to learning with hypermedia

Peer collaboration is a pedagogical method currently used to facilitate learning in classrooms. Similarly, computer-learning environments (CLEs) are often used to promote student learning in science classrooms, in particular. However, students often have difficulty utilizing these environments effectively. Does peer collaboration help students learn with these environments? Little research looking closely at face-to-face peer collaboration with computer learning environments exists. Utilizing a social-cognitive theoretical framework, this study investigated the relation between the conceptual-knowledge learning and the collaborative regulatory behaviors of students working with a peer as they studied about the human circulatory system using a hypermedia CLE. Fifty-four high-school students from the East Coast of the United States were audiotaped to identify the collaborative regulatory behaviors they evidenced as they studied. Results revealed significant correlations among students’ proportion of categories of regulatory behaviors and their learning gains (from pretest to posttest). Moreover, qualitative analyses revealed particular behaviors that larger-gain collaborative pairs engaged in to a greater extent than smaller-gain pairs as they learned with the hypermedia environment.     

Social conversation and effective discussion in online group learning

This paper studies the social talk of high school students in online discussion forums. On-task talk has generally been assessed as valuable discussion because it contributes directly to productive learning. Off-task conversation, on the other hand, is often regarded as useless and a waste of time. Should this social talk indeed be regarded as an off-task activity? Is social talk such as greeting, excusing, comforting and sharing personal feelings irrelevant to learning? This study analyzes threads and argues that social talk is interwoven with on-task talk. It is interesting to note that a substantial quantity of off-task messages served the latent function of guiding group discussion toward making progress in solving collaborative problems in a subtle and indirect manner. The power of “soft talk” embedded in off-task social conversation is explored and fully discussed.
