Beste student

Ik ben, een jonge, gemotiveerde en enthousiaste leerkracht wiskunde-informatica.

Studenten kunnen soms niet altijd goed meevolgen in bepaalde lessen omdat het soms wat snel gaat en hebben soms gewoon wat meer tijd nodig om bepaalde zaken te begrijpen. Het begrijpen van de leerstof is zeer belangrijk. Ik bied daarom bijlessen aan op maat van iedere student! Elke student is anders, leert anders. Door de lerarenopleiding die ik gevolgd heb en de jaren ervaring met bijles geven, ken ik heel veel (online) tools waarmee leerlingen efficiënt en beter zaken kunnen stockeren in het geheugen. De student zal inzien dat leren op die manier ook véél leuker is!

Vakken waarin ik bijlesen geef:
- Wiskunde
- Informatica (Excel, Word, Access, Programmeren...)
- Studiemethode

Contacteer me gerust als je nog vragen hebt. :)

Experienced and patient teacher of logic for computer science.

I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills.

Logic
The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof.
Topics include:
Propositional and Predicate Logic
Syntax and semantics
Semantic Tableaux
Natural deduction
Correctness and soundness
Completeness

Formal languages and automata
A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language.

Topics include:
Regular languages, context-free languages
Finite automata, pushdown automata, Turing machines
Regular expressions
Regular grammar, context-sensitive grammar
Pumping lemmas for regular and context-free languages

Donne cours particuliers sur l’utilisation de l’ordinateur et du smartphone pour débutants à Bruxelles (Kraainem et Wezembeek compris).
Cours en français et en anglais.

• À votre domicile, à mon domicile ou en ligne.
• Possibilité de poser des questions entre les cours par message.

*Pour qui ?
• Débutants ou personnes qui n’ont pas grandi avec les smartphones.
• Ceux qui souhaitent enfin savoir utiliser les fonctions de base de leur ordinateur ou smartphone (Exemples : envoi de mails, utilisation de Word, organisation des dossiers, installation de programmes, utilisation d’un agenda en ligne, recherche sur Internet, etc.).
• Résolution de petits problèmes : boîte mail qui ne fonctionne pas, mise à jour à effectuer, assistance pour contacter un service technique et expliquer dans un langage technique le problème par téléphone.

Disponibilités de 9h à 23h tout les jours chez vous, chez moi ou par webcam.

Pourquoi moi ?
Bachelière Bio-ingénieur 3ème année.
Par le passé, j’ai appris à ma grand-mère de 93 ans maintenant comment utiliser WhatsApp (ce qui lui a permis de nous faire des appels vidéos pendant la période de confinement) et d'utiliser d’autres applications de sa tablette. J’ai appris à ma mère, née dans les années 60, à utilisé les fonctionnalités de base de son PC. J'ai également donné cours à 2 autres grand-mères de mon quartier notamment sur l'utilisation de l'app de la STIB. Très attentive à la personnalisation, je simplifie la matière en fonction de chaque besoin. Je partage des astuces, j'apporte de la motivation et des techniques d’organisation sur PC ou smartphone. Passionnée par le partage de connaissances, je décortique les outils numériques pour les rendre compréhensibles.

Tired of doing the same tedious task over and over again? What if a small Python script could save you hours—every week? Whether it’s organizing files, renaming batches of documents, equalizing the volume of your MP3s, or auto-filling forms, automation is the silent superpower of the tech-savvy.

I build personalized scripts that do exactly what you need, no more, no less. These are not generic tools, but lightweight, purpose-built solutions designed to run on your system and make your workflow smoother.

If you’ve ever said, “There must be a better way to do this,” there probably is. Let me build it for you. Smart code for smart people.

For complex problems you need mathematics, statistics and computer skills to be able to manage it. Once you can describe a problem in terms of numbers then the solution will follow naturally. Get in touch and I will use real life problems to teach you mathematics, statistics and computer science in a very easy way. These subjects are only difficult if the teacher murders it.
