Hypothesis is a social annotation tool that is fully integrated with Canvas. Using Hypothesis, instructors can make PDFs and websites annotatable. Students can annotate course readings collaboratively, sharing comments and replying to peer’s comments. Instructors can also create annotation assignments. Through Hypothesis-enabled assignments, students submit their annotations for feedback and grading in Canvas. This short video demonstrates how to use Hypothesis in Canvas. 

This article provides additional information on Hypothesis use at UWM.

Hypothesis has been enabled for use in all UWM credit-bearing (SIS) courses. There are two ways to use Hypothesis, graded and ungraded. When creating a Hypothesis-enabled Assignment in Canvas, instructors can evaluate and grade student annotations using the SpeedGrader and grades will automatically flow into the Canvas Gradebook.

In contrast to a graded assignment, you can provide an annotatable document or website link directly in the Modules area. This type of Hypothesis-enabled material cannot be graded. Normally, this would be used for readings in which Hypothesis annotation was an optional assignment. This tutorial explains using Hypothesis within Modules in Canvas.

Clearly articulating your expectations for how students should use Hypothesis will go a long way in preparing students for success. Many instructors demonstrate using the tool during a face-to-face class, in a synchronous class meeting (using Collaborate Ultra), or in a screen recorded video (using Kaltura Capture) posted to Canvas. 

Hypothesis provides a guide that serves as an introduction to the Hypothesis LMS App for students. This guide can be linked on Canvas to help orient your students and and support them through out the semester.

Hypothesis also created a video tutorial showing student how to annotate Hypothesis documents in Canvas. You can embed this video in a Page in Canvas and share the tutorial with your students. This tutorial will show you how to embed a video in a Page. This tutorial show how to add a Page to Modules in Canvas.

In general, group size for Hypothesis follows similar recommendations for discussion group size. In-depth, threaded conversations should have smaller groups, ideally between 5-10 students. Groups smaller than 5 may suffer from a lack of new ideas and groups larger than 10-15 may become too overwhelming to follow. In comparison, if you want students to add questions/comments without replying to peers, groups can be larger -- 15-20 students.

Hypothesis integrate with the Canvas Groups feature. Check out this article from Hypothesis.

How can images be included in Hypothesis posts?

• Images that are included in posts must “live” on a website. The image has to be publicly available on the web to add to the annotation post. Images can’t be uploaded to Hypothesis. 
• Once you find an image on the web, right click and select “Copy Image Address” and then paste this address into the image icon in the text editor within a post. Here’s a tutorial from Hypothesis on adding images to posts.
• Google Arts and Culture can be used to annotate images.
• If there’s an image included in a document, you can add annotations to text around an image, but not on the image itself.

You need to have Adobe Acrobat Professional installed on your computer through Creative Cloud. If you don’t have this software, as an UWM employee, you can procure a free license from UITS Software Asset Management. 

Open the PDF and determine if it need to be OCRed. To do this, attempt to select the text. If you can select the text, like the image below, the PDF is OCRed. 

If you can’t select the text, but instead draw a box on the document, like the screenshot below, you will need to perform optical character recognition. 

If you need to perform OCR, click the Tools tab from inside Adobe Acrobat Professional, then select the Scan & OCR button. 

Click the Recognize Text menu and select In this File. 

Then select the Recognize Text button.

A progress bar will appear on the bottom right side of the window. Once completed, save the PDF and upload to Canvas Files using this tutorial.

Here’s a video that Hypothes.is produced on this process:

In rare cases, Acrobat detects that the beginning of the document has been OCRed, but doesn’t continue recognizing the rest of the document. Fortunately, there is a less sensitive, free software tool that usually doesn’t have this problem. After using the OCR detection in OCR Space, Hypothesis recognizes all the characters in the document.

Hypothesis has been seamlessly integrated with the SpeedGrader in Canvas, making it easier to assess student annotations. The integration singles out each student’s contributions to a conversation on a document and enables instructors to enter a grade and written feedback for an annotated reading assignment. This tutorial explains how to use the SpeedGrader to assess student annotations.

When assessing student annotations in the SpeedGrader, you may notice that the submission is shown with a “Dec 31, 2000 at 6pm” date.

This date is a deliberate attempt by Hypothesis developers to allow the tool to work within the constraints of the Canvas SpeedGrader. Because students might visit an assignment, annotate on that reading, leave Canvas, and come back to annotate again, Hypothesis-enabled assignments do not have a “Submit” button, which is required for the SpeedGrader to register an accurate date and time for the submission. As a work-around, Hypothesis uses a hard-coded submission time stamp of “Dec 31, 2000 at 6pm” because this date is far enough in the past to not be mistaken for a real submission date. With that said, each student annotation contains a date/time stamp for the annotation and any edits. As a result, you’ll find the date and time listed on the individual annotation within the Hypothesis tool to be accurate.

Start by creating an Assignment that is an Online submission type. This tutorial will explain the process. If you have not already done so, create the rubric using this tutorial. Attach the rubric to the assignment using these instructions. After the rubric is attached to the assignment, change the submission type to an "External Tool" submission type and setup your Hypothesis reading. Use this tutorial and be sure to select Hypothesis in the "Configure External Tool" step.

Create a PDF of the rubric and then add this to a Canvas Page that describes the assignment and includes the rubric. Here’s an article with some addition information on this option. In your browser, you can "Print to PDF" and then change the settings to allow the rubric to fit on a single page. Then upload the PDF and attach it to the Page as a File. Here’s a screenshot of the settings I used to create a PDF of the rubric in Canvas. This is using Chrome on a Mac, but you could likely adapt the settings to your browser and OS.

How do I make Hypothesis-enabled assignments available in future semesters?

With normal Canvas assignments, you can copy your course to future semesters using the Course Import tool. When this type of copy is performed, Canvas will make a copy of the Hypothesis-enabled assignment or module item, and it will create a copy the PDF file. 

However, there is a known issue in which Hypothesis integration does not update the assignment or module item to refer to the new file. As a result, the new Hypothesis-enabled assignment or module item will continue to look for the old version of the file that resides in the old course. When this happen, Hypothesis shows students and instructors an "Authorize Hypothesis: Hypothesis needs your authorization to launch this assignment" error message. 

 

To fix this issue, you need to re-link the Hypothesis-anabled assignment to the newly copied PDF file. Here is a great tutorial from Hypothesis which explains the process of fixing a broken Canvas File link.
