Teaching & Mentoring Approach

I am an international scientist.

I finished my studies in France and then embarked on a PhD between the Netherlands and Slovenia, where I graduated as a doctor. I ended up in Berlin to work at the Freie Universität Berlin on a research project. I got the chance to teach in Japan last year through an Erasmus grant, and since then, I want to include teaching in my schedule.

I believe teaching is also about compatibility, especially in a face-to-face setting. My vision of personal teaching is that I can solve your comprehension problems and deepen your knowledge in the subject you seek. Everyone has a way to learn; what matters is that in the end, you understood what you came to understand.

I give the first lesson for free since I believe teaching is also about compatibility, especially in a face-to-face setting. Price also depends on your level and your needs and should be an open discussion.

The math, physics, chemistry, and SVT courses of the French or Swiss program of maturity or university are done by either in-depth explanations or by a quick course and summary of essential needs according to the case of each student supported by exercises from the book or evaluations and exams from other high schools.
A special follow-up program to better prepare for the Terminales session.
So that I can give support courses for the 1st year of university in Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Mechanics - Electricity - Chemistry - Organic Chemistry - Biology, Geology.
My experience is too long and for years I have learned methods for each case and for each student to fill in their gaps with the best results of Excellent, Very Good, and Good as mentioned by my students.
I can also help students to better prepare for courses and support them to better prepare for the duties of CNED in science subjects.
Guaranteed response within minutes up to 10 hours maximum.

Chemistry, Physics and Mathematics are usually not the favorite subjects of students. But, believe me - these subjects are so interesting and can be so joyful. If you join my class I will teach you science and how to learn science, so that you can study it by yourself very soon. You will see that Chemistry and Physics are always all around and inside us and that Mathematics is the beautiful and helpful tool we use to just describe and predict them properly.

Depending on your level and the goal that you want to achieve, I will prepare individual customized lessons, will give you guidance on how to learn and to view things - and especially how to think scientifically.

I studied Chemistry at the Technical University of Berlin and graduated there. During and after completing my PhD in Physical Chemistry I worked in Neutron Science and published numerous papers in Physical Sciences. Then I decided to leave science and started working as a freelance teacher in the subjects given above with high enthusiasm in 2011.

Besides that I have prepared many Chemistry and Physics Tutorials on School as well as University level and also published two books with Multiple Choice questions for premed courses.

I am Mavi, a physics engineer working at an aerospace company.
I have been teaching private lessons at the primary, secondary, high school, and university preparatory levels for 9 years. I teach mathematics, physics, chemistry, and science. I have a good command of the curricula of IB, IGCSE, American, Hong Kong, and international schools.

Additionally, I hold the position of president at the Astronomy Society, where I foster my students' interest in astronomy and science beyond the lessons. I prepare the learning environment by incorporating experiments and exploration, moving away from rote education. I often bring experimental materials to class, aiming to make learning memorable through hands-on experiments.

As an educational mentor, I approach my students as if they were my siblings, valuing creativity. I have a deep passion for mathematics, physics, and science. I am dedicated to helping students understand and learn because life encompasses both SCIENCE and ART. The more people I can inspire to know, understand, and love mathematics, physics, and chemistry, the more proud I am.

Become independent and confident in your abilities?
Over the last 5 years, I have had the privilege of supporting more than 30 French students, from middle school (sixth, fifth, fourth, third) to high school (second, first, terminale), towards academic success. My students obtained good averages, passed the certificate, the baccalaureate and the preparatory classes, while strengthening their self-confidence.

My teaching method in 3 steps:

Short term: Immediate improvement in average by assimilating the course and preparing for assessments. This includes assimilating the course, taking notes, practicing standard exercises, anticipating teachers' expectations and test questions, as well as acquiring writing methods.

Medium term: Integration of reasoning and working methods. Your child will learn to work regularly in this order: assimilation, training exercises, preparation for assessments and analysis of results.

Long term: Establishing clear goals, building the steps to achieve them, realizing the SIMPLICITY of mathematics, building confidence in your abilities and unlocking your child's potential.

Details of the formula:

One to two sessions of 1h30/2h per week to assimilate the course and prepare for the evaluations.
Classes delivered via Google Meet for effective online learning.

If you don't like algebra or science scares you then I can tell you the secret of learning these topics with ease. I curate my teaching style to the individual student's needs, such as by giving real life examples or doing small experiments to help understand the topics better.
With multiple examples during the class, daily revision, weekly tests and regular feedback I help students to achieve their desired goals. I can guarantee great results.

This course is aimed at French learners of all levels.

In class, I suggest :
- Interactive learning: conduct conversations, practice pronunciation, improve listening comprehension
- Written skills: Grammar and vocabulary rules. I try to delve into the etymological reasons and connections between different languages to better understand the rules, which helps memorize them!
- Cultural insights: Learn the above points through typical French examples of culture and phrases that will (hopefully) make you dream.

Ideally, lessons would be held in French, because practice makes perfect!
However, we can switch to English or German if necessary.

I can also help with science (chemistry, physics and mathematics), for example with homework.

I look forward to supporting you on your journey to mastering French :)

Hello,
I am currently in my fourth year of higher education, specializing in medical biology research. I speak only French and English, but my academic background allows me to teach a wide range of subjects within biology.

This course is broad and diverse, primarily designed for middle school, high school, and undergraduate students in human biology. I can teach core subjects such as mathematics, physics, and chemistry as they apply to biology. Additionally, I can provide instruction in more specialized fields, including physiology, enzymology, microbiology, molecular biology, and many more.

Feel free to request a specific subject!
