I am miss Patricia, I am native, French-speaking (🇫🇷) having as an activity outside of my studies tutoring. I teach the French language (FLE) and the English language (ESL). I also have skills to teach learners to repeat in math (📐📏✏🔢), chemistry (👩‍🔬🧑‍🔬🧪📗), biology 🫁🫀🦷🥼🔬 (and/or natural sciences 🌏🍀🪰🪱🦠 🥽), French (🇫🇷) and English (🇬🇧).
If you are a parent and you are actively looking for a tutor to supervise your children (help with homework or rehearsals), I am at your disposal. Having a great experience that I acquired by babysitting and serving in youth groups, I was able to immerse myself in the psychology of young people and children and I have this ability to touch their difficulties. . Learning is not the army or a chore, in addition to being an excellent tutor for them, I can also be this benevolent company that will allow them to unleash their potential.
My announcement concerns learners of the French-speaking system (French, Belgian, Canadian) and the bilingual system (French, English).
Through the first course, I would highlight my skills mentioned above and if you are won over, we can continue together.

Level concerned by my ad:

- primary level (any subject)

- middle school level (English, French, mathematics), biology (and/or natural sciences), chemistry

- high school level (English, biology)

If you are interested in this ad, comment with a plus, or write me a private message and together let's make your children better at school.

Miss Patricia,

Javier

Ingénieur diplômé de l’École Nationale Supérieure d’Arts et Métiers (ENSAM), je propose des cours particuliers et du soutien académique en mathématiques, physique, chimie et sciences de l’ingénieur.

J’accompagne des élèves de collège, lycée et enseignement supérieur (licence, BUT, école d’ingénieur), avec une approche pédagogique claire, structurée et adaptée au niveau de chacun.

Les cours peuvent porter aussi bien sur la compréhension du cours, la résolution d’exercices, la préparation aux examens que sur des matières plus avancées telles que la mécanique, la thermodynamique ou la mécanique des fluides.

Mon objectif est d’aider l’élève à progresser durablement, à gagner en méthode et en confiance, en expliquant les notions de manière simple et concrète.

Les cours peuvent se dérouler à mon domicile, en visioconférence (webcam), ou avec possibilité de déplacement au domicile de l’élève selon les besoins.

This class is designed for students in Primary Education and ESO following the Spanish curriculum for Ciencias Naturales and Biología. Lessons support students in understanding key concepts, improving study skills, and building confidence in science from an early age.

We cover topics such as living things, the human body, ecosystems, environment, health, and basic scientific reasoning. Lessons focus on clear explanations, visual examples, and age-appropriate activities that help students truly understand the material rather than memorise it.

My teaching approach is patient, structured, and adapted to each student’s level and learning pace. I aim to create a positive and encouraging environment where students feel comfortable asking questions and developing curiosity about science.

Having graduated with a Master's degree in biology and having worked with students in the French system abroad, I offer support in Life and Earth Sciences as well as help with homework and methodology from middle school to high school.

My goal is to adapt to each individual profile:
– for students experiencing difficulties: review the basics, restore confidence and methodology;
– for more advanced students: to delve deeper, to practice as if for the exam and to aim for excellence.

In Life and Earth Sciences, I work on understanding concepts, scientific reasoning, and preparation for assessments (brevet/bac). I emphasize the scientific method: understanding documents, reasoning, writing a structured answer, and using the expected vocabulary.
In homework help, I support the student in all subjects: work organization, learning lessons, preparing for assessments and time management.

Each session is tailored to the student's needs. I begin by reviewing the difficulties encountered (lessons, exercises, tests), then we work progressively:
– clear explanations of the course with diagrams and concrete examples
– guided exercises to check understanding
– test/certificate/baccalaureate-style training
– summary sheet and revision tips

Patient and caring, I strive to create an environment where students feel comfortable asking questions and progressing at their own pace. I design sessions tailored to each student's specific needs, with regular follow-up between lessons.

I am French, with a Master's degree in Biology, and experience working with students in the French education system in Medellín. I am familiar with the demands of primary and secondary school, as well as the difficulties students may encounter in SVT (natural sciences), French, or with work organization.

I speak Spanish and English, which allows me to easily adapt to Colombian or bilingual students and communicate clearly with families.

I like to teach patiently and pedagogically, respecting each student's pace. My approach combines course understanding, study methods, and practice, so that the student gains confidence and independence.

Each tutoring session is tailored to the student's needs. We begin by identifying difficulties (homework, course comprehension, test preparation) and then work progressively:

– clear explanation with examples and diagrams
– practice with guided exercises
– support with schoolwork
– organization and study method
– exam preparation

For students of the French system, I follow the official programs of the college and lycée.

My goal is for the student to gain confidence, improve their results, and become more independent in their learning.

Modalities:
– Online classes (Visio)
– In-person classes in Medellín and nearby municipalities (Envigado, Sabaneta, Itagüí, La Estrella)

It supports both students in difficulty and those who wish to delve deeper and reach a level of excellence.

- Multimedia resources (flashcards, multiple-choice questions, interactive exercises)

🎯 Learning through experience and immersion
Depending on the subject matter and the learner's profile, courses may include:

Guided question-and-answer session and active training
Concrete examples and real-life situations (science, economics, technology)

Role-playing games and simulations to develop problem-solving, argumentation and critical thinking.

Language immersion: dialogues, storytelling, story creation, comics or manga to learn languages naturally
Creating content (stories, narratives, creative projects) to enhance expression and understanding.

🚀 Learning objectives
Quickly understand complex concepts
Juggling concepts and disciplines to:

- Develop critical thinking, curiosity and autonomy

- Learn to reason, not just to memorize

- Adapt learning to the natural functioning of the brain.

Mis clases están enfocadas en que entiendas la ciencia y no tengas que memorizarla. Partimos de tus dudas reales y de los temas que ves en clase, y los explico paso a paso con ejemplos claros y visuales.

Trabajo con presentaciones dinámicas, esquemas y mapas mentales para organizar ideas clave. Durante la clase relacionamos conceptos, resolvemos ejercicios y aclaramos lo que suele generar confusión en exámenes.

Al final, te llevas material de repaso (flashcards, resúmenes o esquemas) y estrategias de estudio para que puedas recordar lo aprendido y rendir mejor en tus evaluaciones.

Las clases se adaptan a tu nivel (secundaria o universidad) y a tus objetivos: reforzar temas, prepararte para un examen o mejorar tus notas.
