With a background in Civil Engineering, I offer private tutoring in mathematics and science for all primary and secondary school levels. Each student has specific needs, which is why I adopt a flexible and supportive approach. My goal is to help students understand concepts in depth, build confidence, and progress effectively. During the lesson, we begin with a discussion to identify difficulties and define appropriate objectives together. Next, a theoretical review consolidates the foundations before moving on to progressive exercises, encouraging the practical application of the concepts covered. Throughout the session, I encourage students to rephrase concepts and place them in a logical context to solidify their learning. Finally, we take a few minutes to review the session and write a summary of the key points to facilitate revision and memorization. I offer online courses and emphasize the value of online teaching by using interactive tools, screen sharing, and adapted materials to ensure the same clear and effective support as in face-to-face sessions. In addition to the lessons, I offer personalized follow-up with the option of reviewing exercises remotely between classes. Whether you need regular support or occasional help before an exam, I would be delighted to help you progress in a motivating and supportive environment!

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.

This course is aimed at all audiences, children, teenagers and adults, in Switzerland, regardless of age, level or objectives.
It covers a very broad range of disciplines: life and earth sciences, mathematics, physics, chemistry, technology, engineering, arts, foreign languages, literature and humanities.

🧠 A pedagogy designed for the brain
The approach is based on cognitive science and multimodal learning to promote deep understanding, lasting memorization, and autonomy:

- Visual notes (mind maps, diagrams, clear slides)

- Audio notes (oral explanations, mini-podcasts, stories)

- 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.

Each course is fully personalized, evolving and adapted to the individual's pace, interests and learning style.

Clases que transforman la curiosidad científica en comprensión y buenos resultados académicos.

Curso de Biología y Geología dirigido a alumnado de ESO y Bachillerato, preparación de Biología de la PAU, Anatomía Aplicada de Bachillerato y Ciencias para personas adultas.

El curso se basa en una metodología personalizada, adaptada al nivel y a los objetivos de cada estudiante, con explicaciones claras, esquemas, ejercicios prácticos y recursos tecnológicos, como presentaciones digitales, vídeos y materiales interactivos que hacen más atractivas las sesiones y permiten el acceso a una realidad natural que, de otro modo, no sería posible.

En la preparación para la PAU se refuerzan los contenidos clave del currículo oficial y se trabajan preguntas tipo examen y estrategias para obtener la máxima calificación.

En el caso del alumnado adulto, el enfoque es flexible y orientado tanto a la obtención de titulaciones como al aprendizaje por interés personal. El curso está diseñado para quienes sienten curiosidad por la ciencia y quieren descubrir lo apasionante que puede ser entender la vida (Anatomía y Fisiología humana, Citología e Histología, Genética, Zoología, Botánica, Microbiología, Inmunología, Nutrición, etc.)

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.
