Electronic post-exam review for Take Home Exams conducted with RWTHmoodle
If you have done a distance exam (Take Home Exam) by means of the activity "Assignment" in RWTHmoodle, you can use the same Assignment for providing the corrected exam file. For this, use the option to provide a feedback file for the submission made via the assignment. Students will only see their own submission and the feedback file assigned to you.
The feedback file with the corrected exam can be provided for each student via the submission view of the assignment. There are three options:
- Upload files individually via the web interface
- Upload and assign files for all students at once via a suitably prepared ZIP archive
- Partial automation of the steps using the "exam-scan" scripts
In the following instructions, we assume that the submissions of the exam documents have already been downloaded as a ZIP file and corrected offline.
1. Configure feedback type for the assignment
2. Provide feedback files individually
3. Provide feedback files via ZIP file
4. Provide feedback files via script
5. Student view
6. Limit the time and access for reviewing
The steps described below are almost identical for all variants of providing the feedback/review files.
- Open the course room where you want to provide the review files.
- Switch the course page to editing mode by clicking the "Turn editing on" button in the upper right corner.
- On the assignment settings page, go to the "Feedback types" section. Select the "Feedback files" option there. If you want to use the script described below (see below 4. Providing feedback files via script), also select "Offline grading worksheet".
- Under "Notifications", set the "Default setting for "Notify students"" option to "No". This will prevent students from being automatically notified when setting and saving the feedback file (= correcting the exam). Leave "Notify graders about submissions" and "Notify graders about late submissions" also set to "No".
- In the "Common module settings" section, set the "Availability" option to "Hide from students". This will prevent the activity from being displayed to students after it is saved. This way you ensure that students will not see the review file to be provided until you have uploaded all files and manually changed the availability to "show".
- Save the new settings with "Save and display". You will then be taken directly to the submission overview.
In small exams you can upload the feedback files with the corrected exam individually. However, in general and especially in large lectures, providing them via ZIP file (see below 3. Provide feedback files via ZIP file) is easier and faster.
- In the "Grading summary" click on "View all submissions". Now you can see all exam participants and their submissions in one list.
- Click on "Grade" at the persons who should get review to their exam. This will take you to the grading page.
- Upload the appropriate review file in the upload field for feedback files.
- Save the feedback with "Save changes". Alternatively, you can go directly to the next person by clicking "Save and show next".
- Once all files are uploaded, make the assignment visible to students on the course page via "Edit" > "Show".
- Finally, compose a notification or quickmail to inform students that the exam files can now be viewed.
Easier and faster than using the grading view is to provide the feedback files via a ZIP archive. Here, the option to download the submissions as a ZIP archive is used. The feedback files are placed in the submission folders contained therein and then uploaded again in a new ZIP archive. IDs in the folder names are used to correctly assign feedback files to students.
First, perform the assignment configuration steps described above (see above 1. Configure feedback type for the assignment).
- Open the assignment and click on "View all submissions" in the "Grading summary". You are now in the submission list.
- You can skip the following steps 4-6 if you have already downloaded the exam files for correction. You can then proceed directly to step 7.
Scroll down to the bottom of the list and select the option "Download submission in folders" in the "Options" section.
- Next, above the list, click in the "Grading action" field and select "Download all submissions".
- The submissions will now be downloaded as a ZIP archive. Based on the settings made in step 3, the ZIP file with the submissions contains a folder for each student with the name of the person and a submission ID, which contains the documents of the respective person (in the screenshot for student 'Mustermann, Studenta').
- Now place the review files in the appropriate folders. You can name the files freely, but the folder names with the IDs must remain unchanged! Only the parent folder may be renamed, in the screenshot e.g. to "Exam correction".
- Create a new ZIP archive from the folder with the review files.
- In the submission list, click above the list in the "Grading action" field and select "Upload multiple feedback files in a zip".
- Load the file into the upload field and click "Import feedback file(s)".
- On the following page "Confirm zip upload" check the correctness of the data. Click "Confirm" to accept the files. If the information in the zip file is incorrect, for example due to wrong IDs, wrong name spellings or wrong separators, RWTHmoodle will automatically display the message "No changes" after the upload. In this case, check the contents of the zip file.
- RWTHmoodle first shows you an overview of how many feedbacks have been added or updated. Clicking on "Continue" will take you back to the submission list.
- There, the files are assigned to students based on the IDs in the folder names (in the screenshot, the columns with the plus signs are collapsed for space reasons).
- Then make the assignment visible to students on the course page via "Edit" > "Show".
- Finally, compose a notification or quickmail to inform students that the review files can now be viewed.
The steps outlined above in 3. Provide feedback files via ZIP file can be partially automated with the "exam-scan" scripts. This is especially helpful for large exam sessions. Currently they allow the following steps:
- Embed watermark into PDF
- Encrypt PDF
- Create folder structure for upload to RWTHmoodle and place PDFs in the appropriate folders
The scripts "exam-scan" were developed by the IENT of RWTH Aachen University and are further developed and maintained by the IT Center. They work platform independent for Windows, macOS and Linux. Please use the scripts only if you have the required IT knowledge.
First, perform the assignment configuration steps described above (see above 1. Configure feedback type for the assignment). In particular, select the offline grading worksheet in step 3.
- Open the assignment and click on "View all submissions" in the "Grading summary". Now you will see all the submissions in a list.
- Above the list, in the "Grading action" drop-down menu, select "Download grading worksheet".
- The downloaded CSV file contains the assignment-specific grading table with a number of columns. Relevant are the columns "Identifier" (column A: Participant123), the "Full Name" (column B: last name, first name) as well as "Registration number" (column C: 123456).
Please note: The Identifier of the participants from this list is not identical to the registration number, but represents an assignment-specific ID! The file does not need to be open for further use. One of the scripts only extracts the data from the Identifier column. With this procedure, it is also not necessary to download the submissions specifically as a ZIP file, since the script creates the required folder structure on its own. So the script does not use the existing folders with the students' exams, but rebuilds the folder structure for the upload.
- Now follow the steps to use the scripts in the GitLab of RWTH Aachen University. The usage is described in the README.md file. At the end of the process, you will also receive a ZIP file here, which you can upload to RWTHmoodle as described above from step 7 of 3. Provide feedback files via ZIP file.
Once you have made the assignment visible, students can see the feedback file with the corrected exam. You can also download and save the provided feedback file.
Without the following steps the exam files remain permanently available! Therefore, if you want to block access to them, you have to use one of the two options.
6.1. Limit period manually
The easiest way to limit the period for reviewing is to hide the assignment manually.
- Call up the course page and turn it to editing mode by clicking on "Turn editing on" in the upper right corner.
- Click "Edit" > "Hide" behind the assignment to hide the assignment from students.
Once the assignment has been hidden, it can no longer be accessed. If students still have the assignment page with the feedback file open, the feedback file can still be clicked on, but it will no longer be displayed. It will also no longer be possible to download it. Instead, when clicking on the file, the message "Sorry, this activity is currently hidden" appears.
6.2. Limit period and access automatically
To automatically limit access to the insight, use the "Restrict access" section in the assignment settings. Here you can limit access to specific groups available in the course and/or to a specific time window. To restrict access to a specific time window, add a restriction of type "Date" with the start date of the review and a second restriction with the end date. Set the mode of the prerequisites to "must" and "all", which means both restrictions must be fulfilled by the students.
If access should additionally be restricted to a group, add a third condition via "Add restriction", which must also be fulfilled.
With these restrictions, you can ensure that only a smaller group of students can view large reviews and ask questions directly afterwards.
Please refer to the Restrict Access tutorial for details on the setting options.
