By PROFESSOR & PROFESSIONAL COACH

Hello,

First and foremost, I would like to wish you a warm welcome back to school and a peaceful year ahead as you work towards your goals. I am aware that the economic situation can sometimes be challenging, which is why I offer my services to accompany your child throughout their academic journey with ease and serenity.

Throughout my career as a Graduate Teacher and Graduate Professional Coach, I have worked in various contexts. Until last year, I taught in front of whole classes as well as in private lessons. Since this year, I have been providing face-to-face private lessons at home and also via video conferencing, a mode of teaching that I have practiced with university students for the past ten years.

My teaching environment has undergone significant changes, especially with the emergence of the Covid pandemic. This shift has led our secondary school students to adapt to the new mode of learning and communication, namely video conferencing. Despite the success of this transition, it is important to acknowledge that our younger students still require attention and a psycho-emotional connection in order to develop their autonomy peacefully.

Over the past two decades, I have implemented proven methodological approaches, some of which are borrowed from theater techniques, such as the Davis method (mind mappings/colors), and my specialty, professional coaching, which aims to enhance your child's motivation. My main goal is to foster agility in your child across all subjects, not only for the present but also for their future when I will no longer be by their side.

Ultimately, my objective goes beyond simply focusing on gaining points in a subject. I firmly believe in this approach due to my experience as a Mental Coach working with young athletes between Nice and Cannes, as well as throughout Europe via video conferencing, as part of their preparation for the French Tennis Championships. It has reinforced my conviction that working on a subject should be a nurtured objective that encompasses personal growth and development.

As a Professor in General Education, specializing mainly in scientific subjects, I suggest supporting your child in gaining agility in constructing their academic path during this unique period that is filled with both opportunities and challenges.

Looking forward to meeting you soon,
Corinne.

Welcome to my Foundation Course in Science and Maths, specially designed for primary, secondary, and high school students in Amsterdam. This course aims to build a strong foundation in these critical subjects, ensuring students excel academically and develop a genuine love for learning.

My teaching approach is focused on making learning enjoyable and engaging. I incorporate interactive activities and hands-on experiments to bring Science and Maths concepts to life. By involving students in these dynamic learning experiences, I aim to transform abstract concepts into tangible understanding. Each session is thoughtfully designed to keep students interested and motivated, minimizing fatigue and maximizing retention.

I believe in simplifying complex topics, breaking them down into easy-to-understand segments. This approach helps students grasp and retain challenging concepts with ease. Techniques such as mnemonic devices, visual aids, and real-life examples are integral to my method, ensuring that formulas and concepts are not just memorized, but truly understood.

Regular assessments are conducted to track student progress and identify areas needing improvement. These tests also prepare students for their school exams, ultimately boosting their confidence. I understand the importance of keeping parents informed and involved in their child’s academic journey. That's why I provide weekly reports detailing their child’s progress, strengths, and areas for improvement. This continuous feedback loop ensures that parents are aware of their child’s development and can support their learning at home.

Encouraging words and positive feedback are integral to my teaching method. I strive to build students' self-confidence and to instill a love for learning through positive reinforcement. Setting achievable goals for each student, I celebrate their successes and motivate them to strive for excellence. This goal-setting approach not only drives academic success but also fosters a sense of accomplishment and self-worth.

Chemistry is concerned with the physical and chemical properties of substances and the interaction of
energy and matter. The study of Chemistry involves an investigation into chemical reactions and
processes. The discipline seeks to explain and predict events at the atomic and molecular level.
Through the principles of Chemistry, students will understand everyday life, nature and technology, and
the significance of the well-being of man and the environment.

Biology is the discipline in science which seeks to understand the organisation of the organic world
through an exploration of the structure and function of life forms at the molecular, cellular, organismal
and ecosystem levels, as well as the complex interactions and interdependencies which occur at each
of these levels. This knowledge provides the foundation for understanding the opportunities for
promoting the well-being of humans and other living organisms in the environment. It generates an
awareness of the importance of our biodiversity and the unique role of humans in conserving,
protecting and improving the quality of the biological environment for future generations.

A typical lesson includes:

A short review of previous knowledge
A clear explanation of the main concept
Diagrams, examples and everyday applications
Guided practice questions
Independent questions to check understanding
Correction of mistakes
A brief summary and revision task

I do not simply provide answers. I help students understand why an answer is correct and how to solve similar questions independently.

Revising difficult chapters
Practising multiple-choice questions
Solving science calculations
Preparing short and long answers
Reading and interpreting diagrams
Understanding scientific experiments
