Jupyter Notebooks are used in innovative ways to present computational content to students in the field of geosciences. The offerings range from presentation of interactive content, where students require little or no programming experience, to highly complex geoscientific computations. Digital documents in Python were developed for undergraduate students covering concepts such as: stress tensor, strain ellipse, or the mohr circle.

Students can interactively change parameters, for example by using sliders and see the results immediately. Furthermore, they can experiment and extend the notebook by writing their own code within the notebook. Since Jupyter Notebooks for teaching purposes can be provided ready-to-use via online services, students do not need to install additional software on their devices in order to work with the notebooks.

Jupyter Notebooks were used for automatic grading of programming assignments in multiple lectures. The implemented workflow facilitates the generation, distribution of assignments and final grading. Compared to previous grading methods with a high percentage of repetitive manual grading, the implemented workflow was much more time efficient.

 

PetroScan – Development and Use of Virtual Microscopy in the Geosciences

In this application, the functionality of a polarization microscope is simulated. As part of this ETS project, scans of thin sections of different materials in high magnifications and under different light polarization and exposures were collected, combined to form complete data sets, stored and visualized using the virtual microscope. Annotations were included on the images to help students who used the program for self-study. In the lectures, both the virtual microscope as well as polarization microscopes were used. The virtual microscope was well received by both students and lecturers and its ease of use allowed more time to be spent on discussion.

There are a wide range of potential applications using virtual microscopy techniques in the hydrocarbon and mineral industry, and for new developments in geoscience education.
