Introduction and story behind the emergence of this learning activity. What was the need, what issue/problem was the teacher facing and wanted to resolve? 

For this course, due to corona, the exam had to be transformed from a written exam to a digital exam. This is the same as for many other courses. However, for this course, the written exam consisted mainly of equations; exercises and physics problems.  

• Python
• ANS (code editor in ANS)

What has been learned after this lesson/activity has been executed ?

After successful completion of this course students are expected to be able to:  

- Describe simplifications that make thermodynamics quantitative; 

- Identify thermodynamic concepts in real life applications; 

- Perform calculations of thermodynamic properties (e.g. heat, work, energy, entropy, molar Gibbs energy) for ideal gases, pure substances, (non-) ideal mixtures and electrochemical systems;  

- Understand and work with functions of several variables (regarding total derivatives and partial derivatives).

Specific description and demonstration of the lesson idea/learning activity.

When we had to change the written exam to an online exam, we were limited in terms of time available. After a while, we had some more time to think it through. Also, we realised that ANS offered a lot of possibilities. In all, we decided to figure out ways in which the tool could help us.  

In this case we were looking for a way to automatically create different exercises for different occurrences of the exam. This example can also be used within the exam, to create a variable with a changing value per student, making sure that all students have a slightly different exam. The equations for this exam contained different variables and for these variables we indicated a range of possible values; in this way, all exercises differ from each other. In this video it is showed how this was done. 

Mentions tips lecturer has for colleagues based on their experience.

- You can do lots of other things with the help of the editor of ANS. Please also take a look at this showcase: Making partial scores for equations possible in online exams 

- You can create randomized variables with the help of the editor in a Numeric, Order, Multiple-choice and Open question. 

- You cannot use the code editor for ANS Written Assignment (print&scan). 

- You can make use of python libraries in the ANS editor
