GradeChum Mobile Scanner

Introduction

After giving a printed activity, you can scan your students' answer sheets with GradeChum Scanner, our phone app for teachers. You do not need a school scanner: your phone's camera finds each answer sheet, and the app uploads the papers to the activity you choose so GradeChum can check them.

In this section, let's explore how to install GradeChum Scanner, scan your students' papers, and upload them to GradeChum.

Steps

Note: You need a GradeChum teacher account, and a class with a printed activity created on the GradeChum website. Student accounts cannot sign in to GradeChum Scanner.

To scan your students' papers with GradeChum Scanner, follow these steps:

  1. Open the activity in GradeChum. Under Here's what to do next:, click the Play Store or App Store badge to go straight to the app. You can also open the Play Store on an Android phone or the App Store on an iPhone and search for it yourself.
  1. If you are searching, type GradeChum Scanner in the store's search bar and tap the app that is displayed.
  1. Tap Install to install GradeChum Scanner on your phone.
  1. Open the app and log in with the same email and password you use on the GradeChum website: fill in Email and Password, then tap Sign in. The app keeps you logged in the next time you open it.

Note: If you see Invalid email or password, check your details and try again. The app has no reset password link, so reset a forgotten password on the website (see Sign up and log in). No account yet? Tap Create an account to open the GradeChum sign-up page in your phone's browser. If the app later shows Session expired, tap OK and log in again.

  1. You land on My classes. It lists your active classes that have at least one printed activity, including classes another teacher shared with you (marked Shared by: and their name) and mock board classes (marked Mock board). Tap the class whose papers you are scanning.
  1. If you see No classes with activities yet. instead, you have no class with a printed activity to scan. Tap the web address in the message to open GradeChum in your phone's browser, already logged in, and create your class and activity there. Then come back and pull down on the screen to refresh the list.

Note: If the browser says the sign-in link has expired or was already used, log in on the website as usual, or tap the web address in GradeChum Scanner again for a new link.

  1. The class opens on My activities, with each printed activity and its Activity code:. A badge such as 2 sets means the activity has more than one set: tap it to see the set letters. A Linked to 2 classes badge means the activity is shared with other classes: tap it to see which ones.
  1. Tap Scan on the activity whose papers you are scanning. If the class shows No activities to scan yet., it has no printed activity: create one on the GradeChum website first.

Note: Papers you scanned for another activity and have not uploaded yet stay on your phone. Tapping Scan on a different activity asks Discard previous papers?. Tap Cancel and upload those papers first to keep them, or tap Discard & Scan to delete them and scan this activity. Scanning the same activity again adds to the papers you already have.

  1. The first time you scan, your phone asks to let GradeChum Scanner use the camera. Allow it. If you see Camera Access Required, tap Open Settings, turn on camera access for GradeChum Scanner, and come back to the app.
  1. At the top of the scanner, choose Auto or Manual. In both modes the app captures each answer sheet on its own, with no shutter button. Manual waits for you to tap Next after each paper, while Auto moves on to the next paper by itself. The app remembers your choice.

Note: Tap the flash button beside the mode to turn your phone's light on in a dim room. Tap the X at the top left to close the scanner: the papers you scanned so far stay on your phone.

  1. Hold your phone over an answer sheet so the whole page, with its four corner markers, is inside the frame. Keep the phone steady and parallel to the paper. When the page is captured, your phone vibrates and the app shows Successfully scanned! with the paper's number. In Manual mode, tap Next and scan the next paper.

Note: The text on the camera view tells you what to fix before the app can capture the page, for example Position answer sheet within frame, Hold steady - image is blurry, or Adjust angle - hold phone parallel to paper. The wording differs a little on an iPhone. Move the whole page into the frame, avoid glare, and hold still until it reads Capturing....

  1. After scanning all your students' papers, tap Review at the bottom. The button counts your scanned papers against the limit of 100 papers per upload, for example Review (12/100).

Note: One upload holds at most 100 papers. When you reach 100, the app takes you to the papers screen and shows Maximum Reached. Tap Got it, then upload those papers before you scan more.

  1. Check your scanned papers on the Papers screen. To remove a bad scan, tap the paper to select it, tap Delete, and confirm with Delete. To start over, tap Clear all and confirm with Delete All. Tap Back to return to the scanner and scan more. If no papers are left, the screen shows No images to upload: tap Go to Scanner to scan again.
  1. Finally, tap Upload images to upload the scanned papers to GradeChum. When Upload Complete! shows, tap Finish to clear the papers from your phone. Wait until GradeChum has finished checking the answer sheets, then review the results of the activity on the website.

Note: While the file is uploading you can tap Cancel upload: your papers stay on your phone to upload later. If the upload fails, the reason shows under the status. Move to a stronger signal or Wi-Fi when the connection is too slow, remove some papers when the batch is too large, or log in again when your session expired. Then tap Retry upload.

Switch accounts or request account deletion

To see which account you are using, log out, or ask us to delete your account, follow these steps:

  1. On My classes, tap the menu button at the top left. The side menu shows your name and email. Tap Logout to log out right away, or tap Settings.
  1. Settings shows the email you are Logged in as. Tap Sign out to log out and log in with another account.
  1. To delete your GradeChum account, tap Request account deletion. Type why you want to delete your account, then tap Submit Request. A reason is required. Your account is not deleted right away: we review your request and get back to you.

Note: If you already sent a request, the app tells you that you have already submitted a request to delete your account and to wait for our review, instead of sending another one.

And that's how you download and use GradeChum Scanner! Next, let's view the activity results once GradeChum has checked your students' papers.
