Chemistry and Mathematics: Balancing Oxidation-Reduction Reactions

Translated by GoogleSee original

From 13 € /h

Teaching chemistry and mathematics at the secondary level aims to build a solid scientific foundation and develop analytical thinking by connecting shared concepts. Chemistry content includes topics such as atomic structure, reactions, and organic chemistry, while mathematics covers algebra, functions, and calculus. Integration is demonstrated by using algebraic equations to balance reactions, logarithms to calculate pH, and differential calculus to study reaction rates. Effective teaching methods rely on discovery learning, computer simulations, and practical projects that integrate the two subjects. Challenges such as the difficulty of abstraction, individual differences, and time constraints necessitate comprehensive planning by the teacher, varied assessment methods, the stimulation of scientific curiosity, and continuous professional development.

Hi! 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 they can understand the fundamental concepts and excel in their studies. I have teaching experience of 5+ years in Physics and Mathematics to both high school and university-level students.

I have expertise in the following courses:
0. All high school topics

1. Classical Physics (Newtonian mechanics, linear motion, rotational motion, collision theory, angular momentum, and many more)

2. Modern Physics (Electrostatics, Maxwell's law, motion of electrons in electric and magnetic fields, Quantum theory of light, Compton scattering, photoelectric effect, and many more)

3. Optics (Ray optics, wave mechanics, reflection and refraction, Fresnel's law, polarizer, matrix optics, interference, diffraction, and many more)

4. Quantum Mechanics (Schrödinger equation, Heisenberg uncertainty principle, commutation relation, the addition of angular momentum, matrix representation, density matrix, and many more)

5. Solid-state Physics (Crystal structure, wave diffraction, and the reciprocal lattice, crystal vibrations (phonons), the density of states, semiconductor physics, pn junction, transistors, and many more)

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

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 !

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.

Do you want to improve your math skills? Whether for school, exam preparation, or simply as a leisure activity.

I've been teaching math for about 15 years. Over the years, I've met a wide variety of people, including students of all ages and from all over the DACH region (Germany, Austria, Switzerland), as well as students from German schools abroad. My youngest student was 4 years old and my oldest was 56!

During the final stages of my studies, I increasingly focused on teaching until I started working full-time as a tutor about four years ago. Now I tutor students of all ages in Math, Biology, German, and English.

I want my students to enjoy learning. Accordingly, my teaching style is very relaxed. No two lessons are the same, as each one is tailored to the individual student. What I've learned over the years is that every student thinks and learns differently.

I haven't obtained a formal certification in dyscalculia, but I have occasionally tutored children with mild dyscalculia. Depending on the severity of the dyscalculia, I would prefer to refer you to a specialist.
