Mrs. Christie should break down the rubric on how it specifically applies to the student's grade. It is unethical to negatively affect another student's grade based on another student's performance, and thus, makes the assessment invalid. If Mrs. Christie can show data on why the percentage of content mastered was what it was, then the grade should stand (and Mrs. Christie should identify areas in which mastery can be obtained in future assignments). It is also important to use this situation as a teachable lesson for later in life... There is nothing wrong with B's and C's if the person gives everything they have. Too often, American society has redefined success as an A and attending a big college. Success is trying your best and being proud of what you EARN. If data doesn't support validity, Mrs. Christie should throw out the assignment completely for the whole class... Completion grades are not assessments. Poor teaching. Has to have immediate impact or it's a waste of time.

Mrs. Christie should provide the group with a rating rubric. This rubric should be used to discuss each members responsibility, and if it was fulfilled. The student should also understand that in regards to everyone completing their work, she needs to inform the teacher of this immediately, not when grades are published. Mrs. Christie should also meet with the group, and try and identify what work was not equally done, and base the grade after she discusses possible problems and solutions.

If there is proof that the student did most of the work, allow her to finish it on her own. Have the others also finish on their own and receive their individual grade. This will prevent the students from not working well during group work again.

Mrs. Christie should explain to the student that it is too late to complain about group members effort during a project after it has been submitted and graded. If there is a problem with the group and effort of group members, this should be brought to the teachers attention prior to the project being submitted. A separate rubric could be created for each portion of the project and students could be assigned or chose different portions to complete based on their skills and abilities. Once groups have been chosen, each group could elect a leader that would oversee the project portions being chosen, and make sure that all members are completing their portion. At the end of the project, each group member could peer assess the others as part of the final grade to ensure that all members worked equally.
