Möbius Exercises

Möbius Exercises

Ans has won the digital assessment tender and will be TUDelfts’ assessment system for all basic assessments the coming years. The implementation project team will organise the copy of questions from Möbius to Ans which is planned at the end of 2022. Most question types will be copied automatically and some manually. For specific Möbius question types and functionalities, options will be investigated. Möbius will remain available in Q1 and Q2 for formative and summative testing.
We advise lecturers who for the first time in their course create a digital open-book exam or paper-based exam (either closed-book or open-book) to already create these in Ans. Closed–book digital Ans exams cannot yet be administered in the secure digital exam environment (on TU Delft computers) due to technical issues. As soon as this is fixed, this message will be updated.

If you have any questions or concerns, please contact us. For more information, please also visit the Intranet page for the Ans implementation.

Möbius is a web-based system for creating exams, tests, quizzes and assignments. It automatically assesses student responses. Möbius can be used  for summative testing (exams) and for formative testing (exercises). This page elaborates on creating exercises and using Möbius for formative testing. For more information about summative testing using Möbius, please follow this link.

For exercise purposes a special server was installed: the so-called Exercise server of Möbius. This server is linked to your Brightspace course and is used for formative testing. Students are automatically logged in to Möbius when they click on a Möbius link in Brightspace. Their scores are synced with Brightspace Grades.

Why use Möbius instead of Brightspace Quizzes?

  • Möbius has some question types that are not available in the Quizzes tool in Brightspace.
  • Möbius can handle very complex questions, Brightspace Quizzes can’t.
  • If you are planning to use Möbius in your exam (now or in the future) it’s better to start creating questions in Möbius as you can reuse them and your students will familiarise themselves with the system.
  • Questions made in Brightspace Quizzes can’t be imported in Möbius (and vice versa).

Teaching & Learning Support (teaching-support@tudelft.nl) can help you with:

  • Setting up new Mobius classes and place them in your Brightspace course.
  • Setting up the Grades section in Brightspace.
  • Answering questions when using Mobius.

Möbius is only supported in Chrome and Safari. If you have trouble using Möbius, please make sure you are using one of the supported browsers before contacting Teaching & Learning Support.

Firefox, for example, is no longer used for testing and development. This means Möbius will still work with Firefox for now but it is not guaranteed to stay that way going forward.

Setting up Möbius for exercises (formative testing)

If you want to use Möbius, please contact Teaching & Learning Support at Teaching-Support@tudelft.nl. Our team can help with setting up Möbius classes and place the links to the Möbius classes in your course.

When Möbius is added to your Brighspace Course, you will have 2 Möbius classes in your course content:

  1. Question Bank (parent class):
    e.g. ‘IO2070-18 Design for Sustainability – Question Bank’ )
  2. Year Class (child class):
    e.g. ‘IO2070 Design for Sustainability – 2019-2020’)

To keep it organized we advise you to create and manage your Questions in the Question Bank (parent class) and create and manage the Assignments in the Year Class (child class).

The questions you create in the Question Bank will then automatically appear the Year Class of this year but also in the Year classes of the coming years. This way you can reuse questions each year. By creating the Assignment in the Year class, the results of the students will only be visible in this class and not in classes of coming years.

  1. Click on the Question Bank link to Möbius in Content of you Course.
  2. A new tab opens showing the Homepage of the Mobius Class
  3. Click on content Content Repository in the top-menu.
  4. Click on Questions.
  5. Click on Create New followed by Question/text to create a new question.
    Tip: You can organize your questions in groups (these work like folders).
  6. Now can create your question. The Question Name is not visible to Students. On this page you can find short videos of all question types in Möbius.
  7. Click on Save & Close to make  more questions.

Always use Notepad if you want to paste text into Möbius while creating questions. Notepad removes all unnecessary codes.

  • After moving, importing or adding questions. Click on F5 to refresh the screen. This applies to more actions in Möbius.
  • It is not possible to delete a Grade item with Möbius results in Brightspace. So, once you have placed a Möbius link to an assignment on your Brightspace page, never delete it but adjust it.
  • It is not possible to copy/paste an image from a word document. You will need to upload the image via the image button in the edit menu of the question.

  • Do not open Möbius in multiple tabs. Because you can be logged out of one tab (timeout for inactivity), while the other tab looks fine – but then when you save work in the other tab, it doesn’t get saved because your global session is logged out. Information can also get crossed over and the data can get corrupted between tabs/ sessions.

Question settings checklist:

  • Are the number of points per question correctly assigned?
    Check sub questions as well!
  • Do all questions have an option to answer the question?
    E.g. a text box in case of open questions and options in case of multiple choice questions?

A compilation of various questions is called an assignment in Möbius. Follow the steps below to create an Assignment.

  1. Click on the Year Class link to Möbius in Content of you Course.
  2. A new tab opens showing the Homepage of the Möbius Class.
  3. Click on Content Repository in the top-menu.
  4. Click on Assignments.

  5. Click on Default Unit the name of the root folder (you can change this name or create more folders).
  6. Click on Create New > Assignment.

Once you’ve clicked on New Assignment you have to go through a 3-step process:

  1. In step 1 Choose Name give your assignment a name. Don’t fill in the Short name section.
  2. Click on 2. Select Questions, and:
    1. Click on Import Questions.
    2. Click on Questions in the Current Class column.
    3. You will see an overview of the questions you have made (questions with the green icon are questions made in the Parent class).
    4. Select the questions you want by ticking the boxes.
    5. Click on Import.
    6. Change the Points per question (1 point is default).
    7. Change the order of questions by dragging & dropping.
    8. Optionally delete questions from this assignment by clicking the Trash-can icon.
    9. Optionally add questions to the list using the Add-button.
  3. On the tabs in the navigation bar, click on 3. Properties.
    Here there are 5 sections to consider: Type of Assignment, Policy set, General Properties, Scheduling & Visibility and Feedback (after). The settings depend on the sort of homework you want to give in regard to your lectures and teaching activities:
    1. Choose the Type of Assignment, for most exercises: select Homework or Quiz.
    2. Go through the options of General Properties, Scheduling & Visibility and Feedback (after) and select set the settings that are applicable for you test.
      Contact Brightspace support in case you need any help.
    3. Click on Save & Close.
    4. You will see a Summary of all the settings of your Assignment.
    5. If you agree, click on Save & Close again.

Now you will see the assignment in the Content Repository(1) in the Default Unit(2). If you want to edit the assignment: Click on Edit(3).

Assignment Settings checklist:

  • Did you set the number of attempts to the correct value? (mostly set to 1).
    You can find this in the Properties of the assignment?
  • Did you set the Time Limit to the correct value? (Differs per assignment.)

Exam quality checklist:

  • Are all questions suitable for Möbius? E.g. no design questions?
  • If possible, refrain from using multiple select questions.
    Students are punished harder for incorrectly not checking a box, than for incorrectly checking a box.
  • Did you check for asking the same question twice in a single exam?
  • In case of a resit: are the question types the same as in the regular exam?

Fraud prevention checklist:

  • Did you implement parameterization in order to give students unique exams?
  • In case of multiple-choice questions, is Möbius set to present each student with a random question from a question pool of similar questions?
  1. Go to the page in Brightspace where you want to add a Möbius test.
  2. Click on Existing Activities.
  3. Select Möbius Assessment.
  4. A new window appears. Select the Year Class from the list.
  5. Select the Assignment you created from the list.
  6. Click on the button Link to Assignment. 
  7. The assignment is placed on your page as a link.
  8. Click on the Arrow on the right of the link and select Edit Properties In-place
  9. Click on Add dates and restrictions to add the Start date, End date and Due date.
    Adding a time restriction in Brightspace might not be enough. In Brightspace the time duration is leading, not the starting time. Hence, a student can start an assignment 5 minutes before the end and still use his/her full time. To avoid this, it’s advised to add a time restriction in Mobius as well, to ensure a hard deadline. This can be done using the assignment settings in Möbius from this step.
  10. Check Open as External Resource so the assignment is offered in a new tab.
  11. You are all set up.
You can also create a link to the gradebook. To do this instead of Link to Assignment you select Create a link to the Gradebook. This is especially useful when you want students to review their assigment after grading. For more information see this FAQ.

In Möbius it’s possible to Regrade your exam when you have made a mistake in the answering model. There are however some limitations:

  • You can only change the response area. Changing what is asked in the question or swapping out images will not work.
  • When changing answers in Matching, Multiple Choice, Sorting and Clickable image questions, you can only change which answer is the correct answer. It does not work to change the content of the answers.
    Example: If a Multiple Choice question with options a,b,c where b is correct is changed to a,c,b where now c is correct. The students that originally answered b (index 2) will still be considered as having the correct answer when regraded.
  • You cannot change existing algorithm variables. Changes in existing algorithm variables will not be recognized. The original state of the algorithm is used upon Regrading.

Follow the steps below to Regrade a question:

  1. Login to Möbius and go to the Question Bank Class.
  2. Click on content Content Repository in the top-menu.
  3. Click on Questions and open the question that you want to change.
  4. Change the response area in your question.
