You can find details on all the features for exercises involving physical units here. For example on how to create them yourselves or which physical units are currently supported.

This article helps you get started with some example exercises. You can use these exercises to play around with how different check-methods work and how this help you create exercises with specific feedback.

Secondly, you can use these exercises as a starting point for your own exercises or to explore how you can build your own exercises.

You can find all the example exercises here, in on of our community repository. You need to have an Teacher account in Grasple to access these. If you don't know how to create this, please go to www.grasple.com or contact support via the chat icon in the bottom (right).

This exercise checks whether the unit and value are equivalent, but the precision of the answer is ignored. This would be a typical exercise to use for entry level questions to make sure students learn to give answers with value and units and not just values.

This example exercise focuses on providing specific feedback on common mistakes a students make. For example, they forget to provide the unit, use the wrong unit, or have the correct unit but wrong value.

Go to the exercise to see a more detailed explanation, check out the configured answer rules (via the edit view) and play around by giving answers.

This exercise checks whether the unit and value are exact, but the precision of the answer is ignored. This is a specialization of the previous example exercise, with a focus on ensuring students use a specific unit to answer. For example, you want them to use the unit "N" (i.e. Newton) and not "kN" or "kg * m/s^2".

This example exercise focuses on illustrating how you can use the "exact" check and provide feedback on using the "wrong" unit. For more detailed specific feedback, see the previous or next exercises.

This exercise checks whether the unit, value and precision are equivalent. This would be a typical exercise to use for engineering degrees where you want to make sure students learn both to use values and units, but also take into account precision of their answer.

This example exercise focuses on providing specific feedback on common mistakes a students make. For example, they use the wrong precision, they forget to provide the unit, use the wrong unit, or have the correct unit but wrong value.

For an even more elaborate specific feedback see the next example exercise.

This exercise is the extended version of the one above. It also checks whether the unit, value and precision are equivalent, but provides even more specific feedback.

In addition to the specific feedback from the previous example exercises, it also provides specific feedback like "No unit, right value with wrong precision" and "wrong unit, right value with correct precision".
