📋Grading Rules
By default, Rameau applies a match grading rule to each answer box. For example, if the desired answer is the letter A, type A into the Value field in the grade panel when building the assignment and Rameau will automatically look for a match when grading.
In some cases (e.g., roman numeral analysis with figured bass symbols) the teacher may want to give partial credit to a student that correctly identifies either the roman numeral or the inversion. Without grading rules, the default match rule would give zero credit if the student incorrectly answered either the main box answer or the inversion box answer.
Creating a Grading Rule
To create a grading rule, select an answer box and click the Add Custom Grading Rule button.
The Add Grading Rule window displays the Match rule (which is applied to all boxes by default) and any added rules. In this dialoque, you can:
Use an existing rule
Edit an existing rule
Add a new rule
Applying a Grading Rule
Click Use Rule to apply the rule the selected box. The Grading Rule will appear in the right-side panel. In the example below, the "Inverted Chord" rule has been selected.
The options available for Grading Rules in the right-side panel are:
Edit the rule
Delete the rule from this answer box (the rule itself is not deleted from Rameau)
Disclose information about the rule
Add another grading rule
Editing a Grading Rule
In the Add Grading Rule dialogue window, click Edit Rule to open a detailed view of a rule. The "Inverted Chord" rule is displayed below.
A grading rule uses evaluations to calculate correct answers. The three elements of an evaluation are:
Properties
The Operator
Points
In the example pictured above, two evaluations have been added.
The first evaluation has three properties: the top inversion box, the middle inversion box, and the bottom inversion box. The operator is set to equals and the points are set to one.
This means that if the student matches the top and middle inversion boxes, but does not match the main answer box, they will receive 1 point total for the entire answer box.
The second evaluation has one property: the value. The operator is set to equals and the points are set to two.
This means that if the student matches the value of the main answer box, but does not match the answers in the inversion boxes, they will receive 2 points total for this answer box. If the student matches all possible answers, the default match rule will take effect and the total point value, in this case 3 points, will be awarded.
