User Story
As a researcher, I want to have online tests so that I can have pre-test and post-test data associated with my study.
Notes/Comments
- It would be good if DataShop provided the ability to facilitate grading of test data. -- Alida 16:09, 3 August 2010 (EDT) -- From email thread with Bruce McLaren and Vincent Aleven.
- Vincent suggested that DataShop simply put a new field in the transaction export to indicate which transaction is the last transaction for a given step. The researcher would still need to do some work in Excel to produce the actual grades for the students. But this seems relatively simple for DataShop to do.
- Bruce suggested that DataShop take this one step further. Bruce, can you elaborate here more? Do you want a new report?
- Alida wants to throw another idea into the mix.
- DataShop can identify all problems where the tutor_flag field equals, 'test', 'pre-test' or 'post-test'. Then for each step in that problem, find the last transaction for that step and the outcome (CORRECT vs. INCORRECT) and then put two new columns in the student-step rollup export. One column indicating whether the step is part of a test problem. One column indicating whether the student was right or wrong on the last transaction.
- The difficult thing would be actually producing a grade. How would DataShop know how many steps are part of each problem and how many problems are part of a test? If a student skips a step, and there are no logs for that step, then that student would have less steps than another student.

- Last Attempts - Test Items
As a researcher (or educator), I want to see data for last attempts only so I can determine correctness on test items. -- Ruth Wylie, July 3, 2008
