Luca Chiodini

About

Hi! I'm a PhD candidate at USI (Lugano, 🇨🇭), where I work at the LuCE research group under the supervision of Matthias Hauswirth. I also spent a semester abroad at Aalto University (🇫🇮) under the supervision of Juha Sorva. My interests in Computer Science are broad, but my heart lies in teaching. This curriculum describes my path, in case you are interested.

Research

I have been working on improving programming education from several angles. I investigated misconceptions about programming languages, the role of expressions while learning Java, and methodological issues with ad hoc instruments for computing education research. My current main project is PyTamaro, an approach to teach programming using the domain of graphics in an engaging and conceptually deep way. I created an open-source Python library and a web platform which hosts hundreds of activities and dozens of curricula currently used by teachers at multiple educational levels.

Current and past activities

• I have been part of the technical team behind the Italian and the International Informatics Olympiad in Teams.
• I organized six editions of ABC, an Olympiad-style online programming contest held each year in May.
• In 2017, I participated in the first Italian training program in cybersecurity for students. I placed second in a local final challenge and competed with a team in the national final, held in Rome, ranking second.
• In 2014, I won a bronze medal at the Italian Olympiad in Informatics.

Technical blog posts

• What the global statement really means in Python
• Tutorial on how to create images and GIFs with Asymptote

Resources

Over the years I've created and freely shared a number of resources (partially in Italian), which some have found useful:

• Slides of my presentations to train high school students competing in Olympiad in Informatics: regional selection (years 2019, 2018, 2017, 2016) and school selection (years 2019, 2018, 2017).
• My Master's degree thesis, done at LuCE Research Lab to better understand misconceptions when learning to program (related slides).
• My Bachelor's degree thesis, done at Information Retrieval Laboratory to work towards an automatic approach to identify potential binge drinkers on Twitter (related slides).
• My high school thesis, which consisted in developing an automated spelling correction system (related slides).
• Theory of computation class notes.
• Calculus 1 class notes.
• Some solved exercises about signal processing.
• An introductory reading about competitive programming for young students.
• A guide for moving the first steps with JFlex, a lexical analyzer generator.
