Social Loafing01:37

Social Loafing

34.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.1K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Groupthink

44.3K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Group Therapy01:26

Group Therapy

31
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

In- and Out-Groups

39.0K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Group Polarization01:01

Group Polarization

34.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Summary

Problem-Based Learning (PBL) group function develops in three patterns: slow growth, abrupt shifts, or plateaus. Experienced groups often face challenges like abrupt changes or plateaus, requiring novelty to foster development.

Area of Science:

  • Medical Education
  • Group Dynamics
  • Learning Sciences

Background:

  • Problem-Based Learning (PBL) effectiveness is linked to group function.
  • Development of PBL group function over time and influencing factors are not well understood.
  • Understanding group function is key to optimizing PBL.

Purpose of the Study:

  • To explore the development of PBL group function over time.
  • To identify factors contributing to high-functioning PBL groups.
  • To characterize patterns of group function development in PBL.

Main Methods:

  • Qualitative analysis of time-function graphs and focus group discussions with medical students.
  • Students created graphs to depict group function over 8-12 weeks.
  • Analysis guided by Tuckman's Stages of Group Development and PBL Group Function Dimensions.

Main Results:

  • Three archetypes of group function development identified: Slow Shifters, Fast Flippers, and Coasters.
  • Slow Shifters showed gradual growth (Tuckman's model), common in inexperienced groups.
  • Fast Flippers experienced abrupt changes; Coasters faced plateaus, more frequent in experienced groups.

Conclusions:

  • PBL group function exhibits three distinct developmental patterns over time.
  • Tuckman's stages apply to new groups/tasks; experienced groups face disruptions/plateaus.
  • Educators should introduce novelty to stimulate growth in experienced PBL groups.
