Author an organic chemistry question

An organic chemistry question involves students using drawing tools from the Ketcher sketch area to draw chemical structures.

Organic chemistry sketch questions are helpful if you want the student to draw a chemical diagram without having to leave Möbius, or without using a document upload question.

A read-only static rendering of the student's response is shown for both students and instructors, in the Gradebook and in feedback after the assignment submission.

Organic chemistry questions can allow for automatic or manual grading (check out Grading details for organic chemistry questions).

TIP: All questions are authored using the Question Editor. Check out Author a question to learn how to access the Question Editor.

To author an organic chemistry question

To author an organic chemistry question from the Question Editor:

1. Enter the question statement in the Question Text pane of the Question Editor.

1. Click Möbius componentto select the type of student response for this part of the question.

NOTE: A question can have multiple parts, with each question part using a different type of component. Example — A question could contain two components; the first part using a document upload student response, and the second part a multiple choice student response component.

1.  Click Organic Chemistry from the list of student response components.

1.  Assign a weight to the response. The default weighting is 1.

TIP: The weight of the component can be any integer greater than 0, and is calculated proportionate to the total of all weights across the question. Example — A question with two components could have the first weighted as 2, and the second weighted as 4. This means that the second component will be worth twice as much as the first when calculating the total grade for the question.

1. Enter the desired width and height of the drawing area on the students device.

TIP: The size of the drawing area in the question will be fixed. The minimum width and height is 500 pixels, and the maximum width and height is 1000 pixels.

1. (Optional) If automated grading is desired, use the Editor to provide optional correct answer to draw the correct answer that the student will be expected to replicate.

TIP: Check out Grading details for organic chemistry questions for the instructions and limitations of automated grading for this component.

1. Click Insert to add this student response component to the question.

1. The component is inserted into your question.

1. Click Preview to trial your new question to ensure that it behaves as expected.

TIP: You first have to click the save iconif you're creating this question from within an Activity Editor. After the question has been saved, you can then click the preview iconto ensure that your new question behaves as expected.

1. Click Save to save your new question. Your new question is now stored in the Questions pane of the Content Repository.

TIP: Click the save iconif you're creating this question from within an Activity Editor. This saves your question to the activity and the Content Repository.

Grading details for organic chemistry questions

Organic chemistry questions must be manually graded if the Editor to provide optional correct answer isn't filled in.

TIP: Check out Manually grade an organic chemistry question for more details.

The question is automatically graded if a chemical structure is provided in the Editor to provide optional correct answer.

Grading is performed by storing the answer and response in the InChI text format, and then comparing the two strings.
