Interactions and perceptions of distributed groups interacting in an asynchronous computer conference Mary Annette Rose Ball State University 30 May 2003
Have you ever wondered… ? … if the way you organize groups influences the quality of their interactions, thinking, and learning? … how much of the students’ resources were used to “engage learning issues” as opposed to “coordinate” group work? Faculty ROLE
Research Questions • Are there differences in the dialogue (functions, cognitive skills, and levels of processing) between cooperative and collaborative learning approaches? • What are the patterns of productive interactions over time? How do they differ under the two approaches? • What are the group’s perceptions of interdependence and intersubjectivity? Do they differ under these two approaches? Faculty ROLE

Model of Research Study Web-based Course Faculty ROLE
Research Context Technology: Use & Assessment • First offering of a Web-based course • Fall 2000 • Graduate level, 3-credit • Goal “Students will develop the abilities to assess the impact of products and systems.” ITEA, 2000, p.133 Faculty ROLE
Research Participants: Students • 20 of 26 students returned informed consent forms • Off-campus & on-campus (all online) • Degree Sought • Health and wellness (N=14) • Audiology (N=3) • Technology education (N=3) • Relevant Experience • 5% had previously taken an online class • 80% had little to no experience with Blackboard • 67% had formal training with group process/dynamics • 100% reported moderate to high levels of proficiency with group process skills Faculty ROLE
Six Heterogeneous Groups • Individuals assigned to 6 groups controlling for: • Group process skill • Major • Sex • Location • Groups randomly assigned to treatment • Cooperative groups (N=3) • Roles & close monitoring (2 to 3 days) • Schools Specialist • Health & Wellness Specialist • Economics Specialist • Web Specialist • Lead Editor • Collaborative groups (N=3) • Group process is negotiated, no roles assigned • Monitored every 4 to 6 days Faculty ROLE
Problem-based Learning (PBL) Conduct a technology assessment of the health and wellness implications of computer use by children (as if for the U.S. Department of Education.) Deliver a formal online report that makes recommendations for school districts to promote lifelong wellness. Faculty ROLE
Distribution of Messages Study Total = 783 Messages No Difference Significant Differences Faculty ROLE
Distribution of Messages 5.2 messages per student per week Faculty ROLE
Study Comparisons: Messages Face to Face …………………66 to 70% Hillman, 1999 Faculty ROLE
Content Analyses of Messages • Unitized the Message • First, into paragraphs • Then, by single variable (i.e., function or skill) • No smaller than a sentence • Coders Trained and Tested • Developed rater expertise • Reliability analysis (Cronbach alpha) • Ranged from .74 to .89 • Cognitive skill Units coded by at least two coders • Disagreements judged by consensus or third coder Faculty ROLE
Function Variable Cognitive • Learning process • Learning content, issues, and goals Organization • Coordinating joint activity • Management and logistics Metacognitive • General knowledge and skills Social • Off-task statements Henri, F., & Rigault, C.R.

Limitations • Case study, generalize to similar others • Picture not perfect reflection • Only 20 of 26 students participated • Communication occurs in other modes • Thanksgiving holiday at week 4 • Statistical analyses are exploratory and liberal • Hawthorne effect, students aware of observation Faculty ROLE
Implications for Facilitators PBL requiring the delivery of a group product • Promotes learning among distributed learners • groups had high perceptions of interdependence • groups were task driven • Demands learner resources to coordinate group interaction • Only 41% of dialogue was about learning and learning issues • Over time groups’ perceptions of intersubjectivity increased Faculty ROLE
Implications for Facilitators Assignroles because… • May establish common understandings about • group process and • individual responsibility • learning issues • Alleviate learners’ concerns about coordinating joint learning activity • May provide the catalyst on which others can interconnect messages Faculty ROLE
Implications for Facilitators Initially explain and model substantive communication • Define types of dialogue • Examples and nonexamples • Interrelate or weave postings Faculty ROLE
Implications for Facilitators Use interventions that encourage critical thinking: • Identify and question assumptions • Entertain possibilities and defer judgment • Justify assertions and conclusions • Provide elaborate explanations • Detect and classify relationships • Interrelate information Faculty ROLE

Conclusions: Overall Regardless of group structure, PBL conferences were student-driven • students contributed 90% of messages • an average of 5.2 messages/student/week • groups had high perceptions of interdependence • groups were task driven • perceptions of intersubjectivity increased over time Faculty ROLE
Are there differences between cooperative and collaborative learning approaches? • Global differences in function, cognitive skill, and levels of processing could NOT be attributed to group structure. • Cohesion of messages higher in cooperative structure Faculty ROLE
What are the patterns of productive interactions over time?How do they differ under the two approaches? Functions and cognitive skills changed over time • Cognitive dialogue more prominent during mid activity • Organization dialogue more prominent during final week • Inferencing increases, strategies decrease Cooperative structure offered advantages during the initial weeks as evidenced by: • Higher levels of deep processing • Higher levels of cohesive messages Faculty ROLE
What are the group’s perceptions of interdependence and intersubjectivity? Do they differ under these two approaches? Interdependence was high • At mid and final • Across group structure Intersubjectivity • Higher in cooperative structure at mid activity • Increased over time in both structures Faculty ROLE
