Here are some screenshots of our new feature. After the review period is concluded, students can compare the reviews they wrote, with the reviews written by other students for the same homework submissions. In this way, students can see if they were accurate in their reviews, and they can see how helpful they were compared to the other reviewers.
We are considering letting students compare reviews even before the review period is concluded -- the idea would be to let this be at the discretion of the instructor, rather than forced for all assignments. Technically, this is an easy feature to add. The pro is that this would allow a real discussion to take place on homework submissions. The cons is that some lazy students could decide to enter blank reviews, and wait until their fellow students do their reviews to copy the gist from them, with a bit of cosmetic modification. Perhaps saving both the initial review, and the final one, would be deterrent enough.
In the meantime, here are some screenshots of the new feature.
In a continuing effort to make the use of CrowdGrader as secure as possible, and to better protect your data, we are now making CrowdGrader accessible over https.
We encourage everybody to access CrowdGrader over HTTPS, rather than HTTP, to protect your data and your identity. The benefits of HTTPS are:
For the being, we are still allowing unencrypted connections over HTTP, but we are considering making the use of HTTPS compulsory.
CrowdGrader prides itself in offering top security and top reliability to its users.
We have developed a new, simplified UI for CrowdGrader, and we are in the process of gradually rolling it out to all users. The new UI gives you a single list of all assignments in which you are participating, right at the home page, for maximum convenience. That list acts as a global control panel: from that list, you can easily see where you have to submit, and where you have instead to review.
We hope this new UI will make CrowdGrader simpler and faster to use! We would love to hear any feedback.
Assignment managers (both instructors, and TAs listed as observers) can now download all assignment data!
There are two steps required.
First, you need to download a Json file that contains a description of the assignment.
You can do so by going to the assignment, and selecting Download Assignment Data.
Second, you need to get the Python CrowdGrader assignment downloader from GitHub.
You can then run the downloader via:
This will produce a directory in <destination_directory>, and it will create one sub-directory for each submission. In the sub-directory for each submission, you will find the submission metadata, the submission text, the reviews if any, and the files that have been uploaded. The format should be self-explanatory.
The reason you have to go through this two-step process is that an assignment can consist of a very large amount of data (up to several GB for some assignments, depending on the files that have been uploaded). Therefore, downloading an entire assignment can take a long time, and cannot be performed as a single download.
The downloader code is supplied with a MIT license, so please feel free to improve it and to share back your improvements.
We have integrated in CrowdGrader a powerful new editor, which supports math, code, and more. In this way, students can write complex literature, math, computer science, and other assignments directly into the editor used by CrowdGrader, without requiring the use of external programs. As a plus, writing math in CrowdGrader is much easier than in tools such as Word or Google Documents, since CrowdGrader now supports LaTeX/TeX syntax directly!
Here is how the editor looks like:
