تدريس الكيمياء والرياضيات في المرحلة الثانوية يهدف إلى بناء أساس علمي متين وتنمية التفكير التحليلي من خلال الربط بين المفاهيم المشتركة، حيث يشمل محتوى الكيمياء topics مثل التركيب الذري والتفاعلات والعضوية، بينما تغطي الرياضيات الجبر والاقترانات والتفاضل والتكامل، ويتجلى التكامل في استخدام المعادلات الجبرية لموازنة التفاعلات واللوغاريتمات لحساب pH والتفاضل لدراسة سرعة التفاعل. تعتمد طرق التدريس الفعالة على التعلم بالاكتشاف والمحاكاة الحاسوبية والمشاريع العملية التي تجمع المادتين، مع مواجهة تحديات مثل صعوبة التجريد والفروق الفردية وضيق الوقت، مما يستدعي من المعلم تخطيطاً متكاملاً وتنويعاً في التقييم وتحفيز الفضول العلمي مع التطوير المهني المستمر.

My name is Fawzi, and I am a French language teacher. Since 2012, I have been giving private lessons online. My objective is to support learners towards success in the DELF (Diploma of Studies in French Language) or the DALF (Advanced Diploma in French Language), as well as the TCF (French Knowledge Test). I have had the pleasure of helping many students of different nationalities through my online courses. For me, helping enthusiasts practice the French language is an enriching experience, because I understand the importance of success in the lives of ambitious people.

I speak Arabic, French, Spanish, a little English and a little Turkish. During my classes, I explain concepts in French, Arabic or Spanish, depending on your preference. At the end of each session, I offer exercises to do as homework, in order to identify your gaps and monitor your progress.

Here are some essential points to know about the DELF and DALF:
- The DELF (Diploma in French Language Studies) and the DALF (Advanced Diploma in French Language) are two high-quality official diplomas. They are aligned with the levels of the Common European Framework of Reference for Languages and cover the following six levels, from the most basic to the most advanced: A1, A2, B1, B2, C1, C2. These diplomas are suitable for all ages and all audiences.
- The DELF B2 and, increasingly, the DALF C1, provide access to French, European or French-speaking universities, as well as certain Grandes Ecoles.

If you plan to take DELF or DALF exams, or if you want to improve your level, do not hesitate to book your sessions with me to start preparation. I am available !

Hi! Welcome! I am a Ph.D. researcher in Physics at the University of Cologne, Germany. Recently, I graduated from the University of Groningen in the Netherlands with a Master's degree in Nanoscience (w/ cum Laude). I offer private tutoring (for high school and/or university-level students) so you can understand the fundamental concepts and excel in your studies. I have teaching experience of 5+ years in Physics and Mathematics to both high school and university-level students.

This class aims to provide an overview of calculus and linear algebra and focuses on the fundamental mathematical tools and concepts, such as limits, differentiation, and integration. Building on these basic concepts, we will review methods for solving problems related to optimization, linear differential equations, and matrix algebra.

Outline of the course:
1. Calculus:
1.1 Limits of functions
1.2 Continuity, types of discontinuities, intermediate value theorem
1.3 Differentiation (or derivative), slope, secant, tangent
1.4 Rules and theorems for differentiation, power rule, product rule, chain rule
1.5 Derivatives of exp, log, and trigonometric functions
1.6 Implicit differentiation and derivative of inverse functions
1.7 Rolle's theorem, mean value theorem, critical point, maximum/minimum of a function
1.8 First and second derivative tests, inflection points
1.9 Anti-derivative, indefinite integral, integration by substitution, integration by parts
1.10 Definite integral and its application (area between curves, application in physics)\
1.11 Optimization and linear differential equations

2. Linear Algebra:
2.1 Vectors and scalars in Euclidean space, vector arithmetic, scalar product, cross product
2.2 Equations for lines and planes, vector spaces, linear independence, span, basis, dimension
2.3 Linear transformations, coordinates, and representation of linear transformations by matrices
2.4 Matrix operations: matrix multiplication, transpose, determinant, inverse, and Hermitian conjugate
2.5 Systems of linear equations, Gaussian elimination
2.6 Eigenvalues and eigenvectors
2.7 Range, kernel, and rank-nullity theorem

and many more...

*Note that the sessions will be held online (via Discord/Zoom/Microsoft Teams).

Welcome to my Maths, Physics and Science tutoring class, crafted especially for young minds preparing for IB MYP, IGCSE, and GCSE exams. As a passionate learner and dedicated tutor, I am committed to helping students not only comprehend but also develop a love for these captivating subjects. Here's what you can anticipate from my tutoring sessions

Personalised Learning: Every learner is unique, and I believe in tailoring my teaching methods to suit each student's individual needs. I don't judge; instead, I concentrate on understanding their strengths and areas for improvement to create a supportive and encouraging learning environment.

Concept Breakdown: I dissect complex topics into simpler, more manageable parts, making it easier for students to grasp challenging concepts and build a strong foundation in Physics and Science.

Student-Centred Approach: I enjoy teaching students and continually strive to ignite their curiosity and passion for learning. I aim to make each lesson engaging and enjoyable, helping students recognise the real-world applications of what they learn.

Shared Strategies: As a student who has successfully qualified for the Engineering Entrance exam test and is currently studying abroad on a fully funded scholarship, I bring my own learning strategies and study techniques to the table. These proven methods will help students achieve their academic goals.

Continuous Improvement: I am always learning and growing, just like my students. This continuous improvement mindset, which I actively promote, inspires and motivates students to strive for their best. It enables me to stay updated with the latest educational trends and techniques, ensuring that my students receive the best possible guidance.

Supportive Environment: I encourage students to ask questions, no matter how trivial they might seem. By creating a friendly and comfortable atmosphere, I ensure that students feel comfortable and open to express their doubts and curiosities, leading to a deeper understanding of the subjects.

Refresher training, consolidation and in-depth study, training for exams, certifications and competitions or personal projects.

Here is a non-exhaustive sample of the services that I offer:
- skills assessments,
- training for the baccalaureate exam, BTS exams
- practice exams and oral exams for CPGE (Mines Ponts - Mines Télécom - CCINP - etc.),
- training for certifications (Cambridge, TOEFL, TOEIC, IELTS, etc.),
- review and re-explanation of lessons,
- themed conversation, coaching on professional situations...

Prior to the service, we will be able to...
- define needs and potential problems
- carry out a skills assessment based on the CEFR
- co-develop a remediation or progress procedure,
- take into account the learner's courses/documents/learning materials,
- check understanding of the frameworks and expectations of programs, exams, or competitions, etc.

The session is intended to be a linguistic and cultural immersion in English, based on a communication approach.

The approach is multimodal, based on authentic and current resources and uses all language activities to progress (oral and written expression, oral and written comprehension and mediation).

During the sessions, if necessary, learning resources will be provided to expand the vocabulary, recall certain language fundamentals or remind people of a point of methodology.

For certain services (such as oral exams), working documents may be provided in advance.

Education can be complex if it isn't explained well. That's why I've designed my classes as practical and personalized support, intended to help students understand the subjects, gain confidence, and improve their academic performance.
I have a degree in Economics and offer tutoring for all primary and secondary school levels, as well as Economics for higher levels (high school and early university years). I love teaching and supporting my students in their learning process, adapting my explanations to their level, pace, and learning style.
In my classes, I use innovative learning methodologies, combining clear explanations, practical examples, and techniques that foster understanding rather than rote memorization. My goal is for students to grasp the reasons behind concepts, gain confidence, and progress steadily with close and dedicated support.
