Instead of sitting in playing tests scrawling your notes onto a paper rubric and then transferring the data to your grade book, you can complete the grading via a Google Form either on a computer or handheld device (iPad/iPhone).
1. Create your rubric as a Google Form
I have a general template that I use for every playing test. If there is something I want to emphasize in a particular playing test, I create a copy of the form and make the necessary changes. All categories are graded on a scale of 1-4, where 1=Needs Improvement, 2=Developing, 3=Fair, and 4=Excellent. Each category has a question for the grading scale and a short-answer question for specific comments. At the end of the form I have a question for "Areas of Strength" and "Areas that need attention" where I can write more lengthy comments.
2. Create your response Sheet
Link your form to a Google Sheet, and add an extra column at the end where you can use the "sum" formula to add up the numbers in all of the columns with your grading scale numbers.
3. Create a Merge Template
I play around with the formatting to make sure that all of the information will fit on 1 page. Place <<merge tags>> wherever you would like the merge program to insert data from your spreadsheet
4. Load the AutoCrat extension onto your Google Sheet and MERGE!
