  13. Exploring How People Collaborate • So far we did some experiments to get a feeling for this • Face-to-face • Fall ‘03: In a middle school classroom, we observed a face-to-face lesson • Winter ‘04: Taxicab Geometry session in Gerry’s class (university level) • Online • Winter ‘04: 3 online sessions in Gerry’s class • Winter – Spring ‘04: 20 PoW-wow! sessions

  14. What Factors Affect Collaboration?

  15. F2F Experiment I - Sharswoodgroup formation • In the middle school classroom, we observed a face-to-face lesson in which students were grouped by their classroom teacher. • Students were asked to self-assign typical cooperative learning roles (reporter, facilitator, recorder). • Results: They did not continue to use the roles as they worked together.

  16. F2F Experiment II – TaxiCab Geometry Sessions • Student surveys were used to form groups • Decisions were mainly based on availability of students for synchronous communication. • Students were not highly motivated • Depending on their math knowledge and problem solving skills, each group followed very different approaches.

  17. F2F Collaboration in General • + Easy to coordinate discussion, taking turns etc. • + Effective communication channels, can benefit from gestures, body lang. etc. • - Resource limitation, discussed ideas are volatile, could be forgotten etc. • - Access to information resources is limited

  18. Our Experience with Online Experiments – In Class • Groups were initially grouped randomly for the first online session. • For the second two virtual problems groups were the same as in taxicab sessions. (longevity) • Groups used Blackboard software (shared whiteboard, synch chat, equation editor) • Groups did better as they became familiar with the software and their group members • Facilitation instructions • Inscribed-CircleTangent-SquareDucks-in-a-row

  19. Collected information Age Grade Gender Math class Knowledge about math Knowledge about technology How often they join a Pow-wow Our Experience with Online Experiments – PoW-Wow! • Group size • Original goal of 3-4 students • Later goal of 3-5 • With small numbers of registrants, groups were usually small

  20. PoW-Wow! - Facilitation • In initial Pow-wows, instructions were given within the chat room. Later general instructions were printed only on the problem page. • Goal: basic, clear information • Script: Facilitator Information

  21. PoW-Wow! - Recruitment • We have promoted the Pow-wows on the Math Forum site • Problem of the Week index page • Algebra and Geometry problem pages • Instant Messages from MFpowwow to see if registrants are serious and if past participants are coming back • We contacted some active PoW submitters

  22. PoW-Wow! - Statistics • 20 Pow-wows • 37 different participants • 7 repeating participants (2, 3, 3, 4, 4, 6, 11) • 64 never-shows (some registered more than once; some participants were no-shows at times) • VMT facilitators joined 4 chats to fill space

  23. PoW-Wow! - Getting Return Visitors • Problems • Time zones, home schedules, other homework • Kids who register don’t show up • A few rude participants • Software? • Purpose not clear? • What’s in it for the participant? • Socializing, chatting • Math help

  24. Online Collaboration in General • - Coordination is difficult (taking turns, following ideas etc.) • - Limited communication channels • Hard to share your work (e.g. diagram) • Typing issue • + Resources, easy keep a log of the discussion for future reference • + Math resources: Can benefit from online searches to retrieve necessary math info

  25. What Factors Affect Collaboration?

  26. Some Desirable Outcomes of Small Group Collaboration in Our Context • Mastering problem solving (logical reasoning) skills • Mastering communication skills, becoming better collaborators • Developing mathematical thinking; logically linking topics learned in class to solve a problem • Asking insightful questions • Raising different viewpoints, perspectives • Paying attention to other members’ thoughts and needs; providing feedback, help • Critiquing other members’ ideas in a constructive way • Learning from mistakes, making corrections/refinements with the help of other members • Intertwining of perspectives through a process of negotiation; collectively constructing a solution to the problem

  27. To get to the desirable situation… • We need to find out how we should set the parameters effecting the collaboration. • I.e. we need to answer questions like: • How we should form our groups? • What sort of software tools do we need to provide scaffolding? • What sort of facilitation/help features can we build into the system? • What sort of problems should we use?

  28. Approximating Parameters • Answering previous questions requires us to approximate the values of key parameters (especially those regarding skills of group members) • Possible data sources: • Self-assessment data obtained from surveys • Observed performance in previous sessions (if such historical info is available)

  29. Automation Issues • We expect to serve 100s of users around the globe • Due to the projected scale of the system we need • a reasonable group formation scheme • an automated facilitator agent (handle group formation, providing feedback etc.) • a scheme for forming/updating user profiles • updating user profiles according to observed performance
