Develop grading criteria for two assignments, one from each category. Each grading criteria must have some point scale and an explanation for the distribution based on the assignment description provided. The deliverable should consist of two sets of grading criteria with explanations for each. The criteria and explanations of the criteria must be clear enough for another TA to use. Grading of this assignment will be based on the following:
Implementation: 20%
Style: 35%
Explanation: 55%
Implementation will be determined by how clearly the assignment criteria
was designed and stated.
Style covers issues of granularity (level of detail, number of points),
and fairness as well as transferability and consistency. Does the
grading criteria support reducing variability in grading? Does it
have sufficient information to help with consistency across students?
Explanations will be graded by how well it justified the design of
the criteria.
The proportions are balanced the way they are because of the variability of the assignments that you will be developing criteria for. Implementation is fairly straightforward as long as you can state it clearly. On a 2 question quiz, you could just assign 50 points to each question and make it a 100 point quiz. Style is a little more important. Given the last example, it might make more sense to assign a smaller amount to each question for the purposes of significance and ease of grading. Plus, depending on the difficulty of the question, you may have trouble figuring out the difference between a score of 46 and a score of 47 if the granularity is incorrect. These are general style issues but some styles are better than others. Explanation is weighted the most because I'm more interested in learning why you assigned values the way that you did instead of how you chose to do it.
These will be used to motivate the discussion on Friday.
