Educational Trends

• Distributed Learning via the Internet– aka: online, e-learning, web-based

• Collaborative Learning– aka: cooperative, peer-to-peer, group

• Combination = Computer-Supported Collaborative Learning (CSCL)

3

What is Collaborative Learning?

• Peer-to-Peer Interaction & Guidance– Small (2-5) group learning activities– e.g., Discussion (of predefined tasks)

• Cooperative Learning (Johnson & Johnson)– Positive interdependence (shared goals)– Individual accountability– Promotive interaction– Group social skills– Group processing (self-assessment)

4

What is CSCL Discussion?

• Text only versus A/V conferencing• Synchronous (chat) versus asynchronous

(forums)• Instructor guidance via task specification and

discussion moderation• Software application characteristics– Hierarchies and threads

5

Small Group Discussion Task

• Is online discussion for learning a good or bad idea?

• Are there any advantages?• What are some of the disadvantages?

6

Online Discussion Issues

• Variable online technology skills• Mediation of communication (“filtering”) and

its effect on social presence(Short et al., 1976)

• Discussion divergence/convergence• Effects of writing on discussion• Scheduling issues

7

Online Skills & Tool Issues

• Variation in online skills: age, gender, SES

8

Online Skills & Tool Issues

• Variation in online skills: age, gender, SES

• Becoming less of a problem over time • Effect of application functions and interface– Graphic representations, labeling, anchored discussion

• Recommendations: – Provide training and help and start slowly – Consider needs and goal when choosing an application

9

Filtering & Social Presence

• Lack of cues (inflection, body language, etc.) may hinder communication and social presence

10

Filtering & Social Presence

• Lack of cues (inflection, body language, etc.) may hinder communication and social presence

• Compensation: emoticons, chat speak, creative punctuation

• Social presence can and does occur in online discussion (e.g., Clark, 2000; Gunawardena, 1997; Ubon & Kimble, 2004)

• Recommendations: provide for self disclosure and humor (Rourke et. al, 1999)

11

Divergence / Convergence

• Discussion goal: divergence, then convergence – First, maximize competing ideas and argumentation (constructive

conflict)– Then, converge on a group consensus after processing

• Lack of diversity of ideas (lack of constructive conflict)– Some groups diverge spontaneously, but not on task– Rush to agreement, no divergence, premature convergence

• Groups do not spontaneously converge Andreissen, 2006; Andreissen et al., 2003

12

Divergence / Convergence

Recommendations:

• Increase constructive conflict (e.g., with academic controversies) (Smith, Johnson & Johnson, 1984)

• Promote convergence via task and scripts (“reach consensus”)

13

Small Group Discussion Task

What are advantages and disadvantages of communicating only via asynchronous text?

14

Asynchronous Discussion Issues

What are advantages and disadvantages?• Access, non-native English speakers• Interaction is slowed allowing better reflection and

review (Garrison, et. al, 2000; Meyer, 2003)

• Writing has cognitive benefits: increased organization & deeper processing (Lapadat, 2002)

• Recommendations: – Chat for affective goals and brainstorming– Asynchronous for deeper, more thoughtful processing

15

Scheduling Issues

• Discussion must be scheduled and coordinated
