Goals

The basic goal is to foster problem solving skills that can be applied throughout the college experience and the rest of life.

Expectations:

First, you are expected to come to class. I will not be doing much lecturing - you will be working on problems. You are responsible for everything that happens in class. If you miss a class, you are expected to find out what happened, either from me or one of your classmates. Second, you should expect to do much of your learning outside the classroom. Problem Solving, like most subjects, is learned by doing. Most of all, it is expected that you will get excited about what you are learning and take delight in your own, perhaps unexpected, ability to solve intriguing problems.

Grading & Exams:

Teamwork/Classwork		70%
Exam : (June 21)	(1 hour)	10%
Final Exam: (July 5)	(2 hours)	20%

Teamwork

Teamwork assignments will be made in class and posted on the class web page.

Each team consists of three or four members with each member assigned an important role. These roles - scribe, the clarifier, the reporter, and manager - are to be rotated each week so that everyone samples each role. When a team has only three members or one member is absent, the manager takes on one of the other roles.

Scribe: The scribe is responsible for writing up the single final version of the work to be handed in. This is the only set of solutions which will be accepted or graded. Each member of the group will receive the same grade. Whenever possible, your solutions should include symbolic, graphical and verbal explanations or interpretations. Diagrams and pictures should also be provided if possible.

Clarifier: During the team meeting the clarifier assists the group by paraphrasing the ideas presented by other group members, e.g. "Let me make sure I understand, the graph goes up ...". The clarifier is responsible for making sure that everyone in the group understands the solutions to the problems and is prepared to present the problems to the class if the team is called on.

Reporter: The reporter writes a record of how the work sessions went, how long the team met, what difficulties or successes the team may have had (with math or otherwise). If there is disagreement about the solution of a problem, the reporter should present sketches of alternate solutions and explain the difference of opinion. The report should list the members of the team who attended the session and their roles. The report should be on the form Team Cover Sheet and be attached as the first page of the team's solutions.

Manager: The manager is responsible for arranging and running the meetings. If the team has only three members, or if one of the four members cannot attend, the manager should also take one of the other roles. When the home work is returned, the manager sees that it is photocopied and distributed so that each team member's portfolio contains a copy of the corrected problems.

Class Work:

You are expected to come to class. 35% of your grade will be based on work you do and present in class.

Final Exam Study Problems: Three Blindfolded Women, Forty Thieves, Judge, all Bean Games, Planetary Voyage, Jumping Frogs, Cryptarithmetic. Note: Study not only the solutions but also include a careful examination of the logic behind the solutions and be able to explain it clearly.

Three Blindfolded Women: While a red mark was placed on the forehead of each of three blindfolded women seated facing each other in a circle, they were told that the mark might be either red or white. Upon removal of the blindfolds, each was to raise her hand if she saw at least one red mark, and then to take it down if she could logically deduce the color of her own mark. All three hands were quickly raised, but then one of them lowered her hand. How did she know? Carefully explain your answer.
