Four Types of W-goals Four Types of W-goals We classify the W-goals into three kinds of W-goals and an exceptional W-goal: M-PR, M-SR, PR=SR, and CW. The following classification of the W-goals depends on the number of the components PR and SR. M-PR The W-goals of M-PR type can have plural PR-members and single SR-member. M-SR The W-goals of M-SR type can have plural SR-members and single PR-member. PR=SR The W-goals of PR=SR type have only one role for members. In this type W-goal, each member joins in a collaborative learning session on an equal footing: they have the same I-goal, and the same Y<=I-goal is expected for among the members. So we can regard each member as either PR-member or SR-member. The members solve problems and perform assigned tasks in the collaborative learning session. They are expected to get a few educational benefits as secondary effects through the session. For example, a member could develop his/her cognitive skills (i.e., educational benefit), while he/she solves a problem in physics (i.e., assigned task) with other members. In the M-PR type W-goal, the SR-member mainly solves a problem with the PR-member's help. The PR-member is expected to gain an educational benefit from the experience of helping other member. On the other hand, the PR-member mainly solves a problem with the SR-member's help in the M-SR type W-goal. The role of main problem-solver should be assigned to single member, and the role of helper can be assigned to multiple members. A W-goal(Wi) can have a group, which has another W-goal(Wj), as the component SR of the W-goal(Wi). We call the W-goal(Wi) ``CW-goal'' which means a composite W-goal.
