Course: PCC23303 Introductory thermodynamics B

Period: Period 5 & 6

Short Introduction and background

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.

Relevant tools / apps (software) or hardware used

  • Python
  • ANS (code editor in ANS)

Learning outcome(s)

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).

Lesson idea / Learning activity

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 automate the scoring of the outcome of equations, as partial correct answers should also result in obtaining a part of the points per question.

Lessons learned / Tips

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: Easily creating different but similar exam questions with equations in online exams

- You can create partial scoring with the help of the editor in a Fill-in, Order, Statement, 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
