JuliaCon 2022 (Times are UTC)

Teaching with Julia (my experience)
07-27, 12:40–12:50 (UTC), Green

I am tenure at the University and I teach several courses of Computer Science. In this talk of 10 minutes I will teach how I will my use of Julia as a useful resource for teaching. In this talk I will introduce how I have used Pluto/PlutoSliderServer to explain concept and to allow students to check some implementations. Also, I show an online web for creating easily online quiz for Moodle. Finally, I have used it to prototype some algorithms that later the students should implement.

I am tenure at the University and I teach several courses of Computer Science. Some time ago I started to use Julia in my research, and more recently I have started to use it as a teaboth ching resource. In this talk I do not refer Julia as the programming language for students (they are last courses in which students can use whatever programming language they want), but as a resource to create tools to help me in the teaching.

In this regards, I have used Julia in three different approach, that I will quickly cover:

  • For explaining concepts, I have used Pluto notebooks to visualize them. Also, recently I have used PlutoSliderServer (as Pluto but without editing option) to allow students to check some calculations they have to do during their exercises. An example is https://mh.danimolina.net/ (in Spanish).

  • Due to the pandemic period, the use of online tests in Moodle has increased a lot. There are several formats to create them, but they are not intuitive enough for non-technical people. In order to solve that, I have created an online web to create easily the online quiz for Moodle (https://pradofacil.danimolina.net/, in Spanish), with a simple syntax that people from different background can easily use it.

  • Finally, in some courses student must implement several algorithms. In order to identify the best parameter values, and to identify the best approaches to implements them, I previously solve them in Julia. Also, it has serve me to predict how much computational time they will require. In my experience, although some specific implementation in C++ is faster, the average implementations takes similar time than using Julia. Many implementations are slower than my Julia implementation, due to some developing decisions.

I consider this talk could be interesting for audience due to the following reasons:

  • It gives a very general view of the possibilities of Julia as a teaching resource.

  • It can be useful for other teachers giving ideas of integrating Julia in their portfolio.

  • It shows my personal experience, and the feedback obtained.

I will be able to prepare the talk both in English and in Spanish. If it is accepted I will create an English version of the shown resources.

I am tenure in Computer Science at the University of Granada, Spain. I strongly support free software in my life and use it daily in my teaching. I learned Julia more than a year ago, mainly for research, in Machine Learning and Optimization, but also for teaching.
