This lesson will describe the various Settings available for use when scanning with GradeCam.

Where to start
Go to Assessments > List Assessments and select an assessment from the list. Once in the assessment, select to Scan Student Responses. This will load the GradeCam scanning page and scanning window. Under the scanning window, click Tools > Settings.
1. Selected Camera
Allows you to pick a particular camera connected to your system that you wish to use to scan. Be sure to plug the camera in before opening your web browser.
2. Flip Image
Allows you to flip your camera image 180 degrees. The sheets should be right side up (not upside down) when viewed in the GradeCam window. Adjust accordingly.
3. Prompt me for unexpected blanks and/or multiples
Allows you to control whether or not GradeCam will pop-up unexpected answers (blanks and multiples). Unchecking this setting will decrease the number of times this pop-up will appear, since it will no longer prompt you for unexpected blanks or multiples.
This setting is useful when scanning results for younger students who may not have filled out every question and for test where students have bubbled in answers using pen (since erroneously marked answer cannot be removed). With this setting on, GradeCam will look at your answer key to determine the number of filled in bubbles for each correct answer and compare to the selected answers on the student's answer sheet. If the answer is blank or if the multiplicity is higher than expected, GradeCam will prompt you. For example, if the correct answer is A, but a student as marked AE, the multiplicity of the correct answer is 1 and the student marked answer is 2. Since the multiplicity is higher than expected, the GradeCam prompt will appear.
1. GradeCam should "think" about marks for no more than
This controls the maximum time GradeCam will spend trying solve problems it encounters. When GradeCam suspects there could be an issue with bubbling, it will try to improve the accuracy for no longer than the set amount of seconds. If after this amount of time GradeCam cannot confidently and accurately read the form, it will pop up the dialog box, prompting you to intervene and "help" it figure out the questionable bubbles. If GradeCam is able to read all bubbled answers within this amount of time, it will scan as soon as possible and no pop-up prompt will appear. If you want to use standard/default time, select 3 Seconds.
2. My trust level in GradeCam's ability to resolve issues is
This controls the maximum predicted error probability with which GradeCam will determine which answers are bubbled (in other words, its sensitivity to error). This impacts the frequency with which the pop-up window can appear (prompting you to indicate which answers to use when GradeCam can't determine 1 or more bubbled answers). Thus, the smaller the chance of error, the more frequently the pop-up prompt can appear. If you want to use standard/default sensitivity, select .001 - Moderate - Normal Popup Activity
TIP: Once you are assured of GradeCam's accuracy, you can adjust the default settings to help improve scanning speed.
