How general answer comments fit into Canvas quizzes

Adding general answer comments to Canvas quiz questions helps students learn from their mistakes right after they submit a response. A good comment tells them why the correct answer is right and names the misconception behind the most common wrong choice.

Keep each comment to one to three sentences that state the reasoning, not just the letter.
Name the misconception behind a wrong option so students can correct their thinking.
Tie the explanation back to the wording in your lecture or reading so students can find the source.
Check that the comment still makes sense once the quiz is imported into Canvas.

Example feedback comments for Canvas quiz questions

Which best describes general feedback on a quiz question? A) Shown only when one wrong option is chosen B) Shown after any response C) Shown only to instructorsB, because general feedback appears after any submitted response, so it suits explaining the concept behind the question.

True or false: a per-answer comment appears only when that specific answer is selected.True, so use per-answer comments to address a common misconception tied to one distractor.

Why should feedback explain the reasoning instead of only naming the correct letter?Students who missed the question need the reasoning to fix their understanding, and a letter alone does not show why an answer is right.

What should a feedback comment for a wrong answer include?The reason that choice is incorrect and the correct reasoning, in one or two sentences tied to the source material.

How many feedback comments should one quiz question have?Usually one general explanation plus a short note on the most likely wrong answers, which corrects common mistakes without overloading the student.

Generate the full set

Feedback for every answer

Each generated multiple-choice, true/false or short answer question includes an explanation you can use as general feedback.

Built from your material

Comments are based on the PDF, DOCX, PPTX, notes or photos you upload, so the feedback matches what your students actually studied.

Export for Canvas

The Pro plan exports QTI 2.1 files, which Canvas can import, so your questions and comments move over without retyping.

How it works

Upload your source

Add a lecture deck, chapter PDF or typed notes. Photos of printed pages are read with text recognition.

Review the questions and comments

Check each question, its correct answer and the explanation. Edit any comment that needs your own wording.

Add feedback in Canvas

Copy the comments into Canvas, or export a QTI 2.1 file on Pro to import the questions.

Writing these comments for every question takes time, especially when a quiz covers a full unit. DeckOwl reads your course material and drafts a question with an explanation for each one, so you can review and edit instead of starting from a blank page.
