See the Requirement Guidelines for In-Class Exercise (ICE) assignments.
This is an in-class group assignment. Fill in the names and email PIDs of the group members in the space provided below so that each group member knows who is in the group. Submit one copy of this to your instructor before you leave class.
| Group member name | Role | VT Email PID |
Pick a solver and a scribe for your group; the remaining members will play the role of listeners. Identify the role taken by each group member in the table above.
Follow the Solver/Listener paradigm to analyze and attempt to solve the given problem. It is important that you manage the discussions in a disciplined manner so that the scribe can take adequate notes to prepare a transcript of your session.
When you believe you have a solution to the problem, work together to prepare an outline to help the solver present your results to the class.
After the class, and by the announced deadline, prepare a written presentation of your session, including the interactions between the solver and the listeners and a detailed explanation of how you arrived at your solution. You may include diagrams and mathematical work if you used those as part of your process.
Only one group member, the scribe/recorder, must submit that to the Web-CAT System via the collection point for ICE01. The scribe must select the partners on the Web-CAT at the time of the submission.
Remember that the evaluation of your solution will depend primarily on the completeness and clarity of your explanation.
