The literature on the use of problem-based learning in K-12 settings has traditionally focused on gifted and average students. However, mainstreaming is placing increasing numbers of students with special needs in general education classrooms. This case study examined how members of a small group in a mainstreamed seventh grade science class…

Although estimations typically possess correct answers, these answers may be difficult to demonstrate to others. However, providing external information may increase their demonstrability. In this experiment, individuals (N = 60) and 6-person groups (N = 360) generated estimations with or without frames of reference. We hypothesized that…

A look at two areas of research in group dynamics: Individual behavior conformity to certain pressures of group processes, and the "risky shift phenomenon," which theorizes that the group tends to be a more dynamic and venturesome unit than does the individual acting alone. (Author/HB)

Operational definitions of two key variables in group communication can provide a theoretical perspective for considering communication behavior in group research: "risk taking," the tendency to prefer long shots with higher payoffs over sure things with lower payoffs; and the "risky-shift" phenomenon, the finding that after…

Reviews group behavioral issues from past space missions and simulations such as the Skylab Medical Experiments Altitude Test, Skylab missions, and Shuttle Spacelab I mission. Makes recommendations for future flights concerning commandership, crew selection, and ground-crew communications. Pre- and in-flight behavioral countermeasures are…

Describes a model for sequential stages of group development based on yogic chakra system. Compares chakra-based model with other models of group developmental stages. Using context of chakra system, specifies basic dynamic issues and leader interventions for each stage and discusses relationship of individual development to group process. (Author)

A common challenge in many situations of computer-supported collaborative learning is increasing the willingness of those involved to share their knowledge with other group members. As a prototypical situation of computer-supported information exchange, a shared-database setting was chosen for the current study. This information-exchange situation…

Individuals organize their behaviors in light of the social groups of which they consider themselves a part. Risks shared between individuals take on symbolic significance and become cultural meanings for those involved. In other words, risks provide content for creating shared knowledge significant for group relations. This study examined the…

Examines the proposition that members of a group unconsciously displace the shadow of the group onto other groups to reduce feelings of internal conflict and threat within the group. Characteristics of the group shadow, as well as its psychodynamic function within and between groups are described. (Author/BL)

Reviews literature concerning newcomers in groups in different settings. Presents a general model examining factors felt to be important for successful assimilation in group psychotherapy, i.e., overcoming resistance to join group, clarifying group process, examining client's in-group behavior, and confirming client's expectations. (BH)

The results of these experiments strongly suggest that the occurrence of behavioral contagion depended on the relative advantage an initiator's action establishes over the other members of the group. (SD)

Analyzed structure of social interaction within four therapy groups in terms of conditional responding of participants. Proposed that groups' interactions would show increasing structure across sessions. Findings showed no consistent pattern of group development, that frequency with which members spoke was inversely related to dominance in group,…

Examined relationship between group members' (N=36) approach to group sessions and group session climate and relationship between length of time in group and agenda quality. Found average ratings of interpersonal and here-and-now dimensions of agendas were significantly related to average perception of group climate as more engaged and less…
