# My teaching activities¶

Note

I am *Lilian Besson*, a former student in Mathematics and Computer Science at l’ENS de Cachan. I am a passionate programmer, open-source enthusiast and young researcher in machine learning, learning theory and cognitive radio. I also love to cook and meet people, to travel and exchange, to bike or hike.
Welcome to my website.

## In 2017/2018 and 2018/2019¶

I continued to teach, about 64 h / year, for 2017/2018 and 2018/2019, during my PhD in Rennes (France), at ENS de Rennes (for the « agrégation » national exam) and ENSAI (complexity and computability).

I gave oral exams and programming practical sessions (for OCaml) at ENS de Rennes (about 20 times 2h, level M2), and I was a teaching assistant (TA) at ENSAI (4 times 3h, for two groups, level L3).

- For more details on the oral exams I am giving for the « Computer Science option for agrégation » at ENS de Rennes, see this page (2017/2018 and 2018/2019).
- For more details on the TAing I am doing for the course « Complexity and Computability » at ENSAI, see this page (only 2017/2018).
- I helped for some practical sessions theoretical computer science using OCaml, for students in prep” school (MPSI), at the Lycée Chateaubriand, in Rennes (not paid).
- I gave again some training sessions for the exam in Computer Science for students in prep” school for the CentraleSupélec national entrance exam (PSI), at the Lycée Joliot Curie, in Rennes. See the solutions of the problems we covered.

Note

I also evaluate research internship reports for students finishing their first year of Masters degree in theoretical Computer Science, at ENS de Rennes, as well as oral exam for students finishing the Bachelor degree and defending the thesis they wrote during their summer internship (September 2017 and 2018).

## In 2016/2017¶

I had a teaching load of ~ 64 h / year, for 2016/2017, during my PhD in Rennes (France), at ENS de Rennes (for the « agrégation » national exam) and ENSAI (complexity and computability).

I was giving oral exams at ENS de Rennes (about 20 times 2h; level M2), and I was a teaching assistant (TA) at ENSAI (4 times 3h, for two groups; level L3).

- I also gave some training sessions for the exam in Computer Science for students in prep” school for the CentraleSupélec national entrance exam (prep” school PSI), at the Lycée Joliot Curie in Rennes. See the solutions of the problems we covered (not paid).

Note

Extras :

I was also in charge of evaluating research internship reports for students finishing their first year of Masters degree in theoretical Computer Science, at ENS de Rennes, in last September 2016. I gave a few practical sessions in programming and maths for students in Rennes training for the national competitive exam for CentraleSupélec engineering schools in June 2017. And I went to Lycée Pasteur in Lille in July 2017 to attend a lot of oral exams for the national « agrégation de mathématiques » competitive exam (maths, modeling and CS).

## In 2015¶

### Second semester of 2015 (in France)¶

Between September 2015 and June 2016, I was teaching, on a weekly basis, at Lycée Lakanal (at Sceaux, near Paris) in a preparatory class (MP), as:

- a teaching assistant for regular oral exams in Mathematics (2 hours a week). My references for the course content and the tutorial problems are these (
*French*) websites: mp.cpgedupuydelome.fr (mainly), these exercises by Nicolas Martin and by Loïc Devilliers, and « Le Frido », and this True/False by Roger Mansuy (and Wikipedia, of course). - and as a Teaching Assistant for the common Computer Science course (based on this good book), with Python 3k and the open-source Pyzo environement (2 hours every 2 weeks). My references for the course content and the tutorial problems are Python’s documentation, introtopython.org and these problems written by Jill-Jênn Vie.

Complete solutions for the *Computer Science* course:

Hey, you can have a look to my solutions: to some algorithmic problems (written), to some written exams about algorithms and data structures, as well as some programming problems (implementation, on a computer, during a practical session) and exercises for the oral exams. I was doing my best to provide full solutions for every week, and keep them up-to-date. Feel free to explore them!

The solutions (Python files) are all in open access (→ infoMP/ folder), in French, and also open-source (on bitbucket.org/lbesson/info-mp-2015-2016).

Note

Replacement in BCPST-2A (2nd year biology prep” school)

Between November 2015 and February 2016, I also gave one weekly hour of oral exam (in maths) for a class of BCPST 2 prep school.

Total: | For the scholar year 2015-16, I evaluate my teaching load to be about 106 hours (number of hours teaching to a group of students, or in charge of a practical session or an oral exam). |

### First semester of 2015 (in India)¶

CS101 @ MEC: in charge of the CS labs (practical sessions) and in charge of certain lectures! It was about 4 hours a week of CS labs, during 17 weeks, and 4 hours a week of lectures for 5 weeks (lectures were in an amphitheater of 115 students!). The slides for some of my lectures are here:

*« About data-structures in Python (lists, sets, dictionaries) »*: slides_CS101_part3.pdf,*« Then, about the use of files in Python (open, read from and write to a file) »*: slides_CS101_part5_1.pdf,*« And finally an introduction to scientific plotting in Python with MatPlotLib »*: slides_CS101_part5_2..

More resources are available:

- Exams (CS101): exam papers and complete solutions,
- Labs (CS101): assignments and complete solutions for the practical sessions (labs),
- Solutions (CS101): solutions to various website or books about learning Python.

Projects: In April 2015, we gave to our students a programming project, and my teams had two projects: one about matrices and linear algebra operations (→ mec-cs101-matrices.rtfd.io) and one about numerical integration techniques (→ mec-cs101-integrals.rtfd.io). I wrote the complete solutions for these two projects, in Python, and they are hosted on ReadTheDocs.org. Examples: This new git repository (python-demos) now hosts about 60 examples of Python programs, involving various domains (such as image processing, scientific plotting, numerical or symbolical calculus, machine learning, linear algebra etc). These examples were and are here to illustrate what I covered during my lectures, in March and April 2015. Hackhathon: For Pi day 2015 (3.14.15), I organized a huge hackhathon about *pi*(the number, but also*pie charts*). The written exam paper for the hackhathon is available here (publis/hackhathon). About 50 students worked on it and had fun together on that day!MA102 @ MEC: in charge of one group for Maths tutorials (linear algebra and multi-variable calculus).

More resources are available:

- Exams (MA102): exam papers and complete solutions,
- Assignments (MA102): assignments and some solutions for the practical sessions (tutorial),
- Techniques (MA102): some small documents summing up useful techniques of computations and proofs,
- Quiz (MA102): small quiz exam papers and solutions.

I am also at the origin of an initiative to help our MEC students by giving them lists of things to read or work on during the 2015 summer (

*work in progress*).

Total 2: | For the first semester of 2015, I evaluate my teaching load to be about 140 hours (number of hours teaching in front of a group or an amphitheater of students). |

## In 2014¶

### Second semester of 2014 (in India)¶

MA101 @ MEC (July – December 2014). In charge of 3 groups (out of 8) for Maths tutorials (introduction to calculus and logical thinking). 6 hours weekly, during 17 weeks (~ 102 hours).

More resources are available:

- Assignments (MA101): assignments and some solutions for the practical sessions (tutorial),
- Techniques (MA101): some small documents summing up useful techniques of computations and proofs,
- Quiz (MA101): small quiz exam papers and solutions.

Total 1: | For the second semester of 2014, I evaluated my teaching load to be about 110 hours (number of hours teaching in front of a group or an amphitheater of students). |
---|---|

Examens: | During the whole year, I was also in charge of the exam papers for Maths and CS: conceive them, merge the ideas from the colleagues, then write everything (in \(\LaTeX2e{}\) of course), and write a complete and detailed solution, grade myself some of the papers and also overlook the grading done by my colleagues… With a total number of 9 exams (3 for MA101, 3 for CS101, 3 for MA102: 1st and 2nd Mid-Term, and Final), and about a dozen of quiz papers and lab exams, I became quite skilled at this kind of things. |

### First semester of 2014 (in France)¶

- Regularly grading exam answer scripts @ corrections-rue-ulm (exam answer scripts of high-school students, in mathematics).
- Occasionally helping high-school students and in charge of oral exams (at the level of Baccalauréat), with the « Cours Thalès » organization.

Note

In 2014, I also got admitted to the French national competitive exam for becoming a prep” school professor (*« agrégation »*) in mathematics (with a major in maths, minor in CS).

Here are a lot of resources for preparing the exam (in French).

For the two scholar years 2014-15 and 2015-16, I asked to postpone the beginning of my carrier as a professor in the French secondary education, in order to properly conclude my training at École Normale Supérieure de Cachan (ENS of Cachan) (thanks to the choice *« fin de scolarité normalienne »*).
From 2016-17, I am teaching 64 hours / year, to validate the internship require to become a full-track professor (« professeur agrégé »).

## Between 2009 and 2013¶

Nothing serious, but I used to regularly help my friends for Chemistry, Engineering, Physics (2009-2011), and Maths and Computer Science of course (2009-2014).

## Before 2009 (high-school and before)¶

I used to regularly help my friends for Maths, Chemistry, Biology, Physics… but alsotheater.
