Personal Description:
I work as a practicing artist, lecturer and illustrator I feel extremely lucky have been able throughout my working life to combine two of my favourite things, art & nature.

My award winning work has sold widely across the UK and in the USA. Careful study, thoughtful composition, and atmosphere are the key elements that go into my personal work.

I have been an external examiner for several programmes and I am currently a certfied moderator for Access to HE Art, Design & Media Diplomas through Ascentis.

Teaching Experience:

dI have over 25 years experience teaching degree level, HND and ND levels of illustration, drawing and illustration industrial placement. More recently I have collaborated to design workshops and short courses in art and illustration, working with organisations and individuals. My private 1:1 tutoring often involves preparing students for 'A' Level, college and university or building portfolios for further education.

Many of my university students have gone on to be leading professionals in the creative industries, but you may wish to have lessons to improve your technique of a media or drawing application, as a leisure painter.

Tutoring Approach:

My background is in natural history illustration and wildlife art, working in a variety of media including; watercolour, acrylics, graphite and oils. However I can plan engaging lessons that will help you develop an understanding and skills to convey tone, form colour and light for whatever subject you are interested in.

Through patience, understanding, and working together I will help you achieve your artistic goals. I create wildlife art in a variety of media but teach across a wide range of subject areas in art & design from landscapes to still life.

I have a special interest in teaching the principles of observational drawing, covering skills that can be applied to all visual mediums in art.

Personal Description:
Highly motivated physics Tutor.
Teaching experience accumulated by preparing more than 40 students for A-Level exams.

Teaching Experience:

My name is Anton. I have master`s degree in Physics from University of New Hampshire. Besides my background as researcher I have four years of experience as a London based tutor. I primary teach A-level physics and most of my students were taking OCR, AQA, or Edexcel exams. I occasionally teach GCSE and University level subjects, such as Mechanics, Electrodynamics, and Quantum Mechanics. Currently I teach part-time in a private school.

Tutoring Approach:

My approach to teaching is flexible. Usually I easy detect weak spots in students understanding and this gives me chance to focus on the most relevant topics for a particular student. I carefully prepare myself for each session, and my goal is to make the student involved in the lesson not just leaving him to listen to me. In my opinion the Math involved in A-Level physics is not hard at all, and many students that are good in Math think they can handle physics relatively easy, but this is most of the time not true. I apply extra effort, in my lessons to make sure that student understands the physics concepts not just memorizing facts. My observation is that if the student goal is to achieve an A grade it requires at least two hours of tutoring per week throughout the academic year, of course sometimes one hour is Okay, and some ambitious student ask for more than two hours per week. In any case it will give me great pleasure to help you improve your knowledge and make you feel the beauty of PHYSICS.

If you have any questions please let me know.
Good luck,
Anton

Personal Description:
Although I now have a PGCE in mathematics I have been lucky enough to get the chance to apply my skills in maths and physics whilst working as an engineer in the automotive and white goods industries. It gave me the opportunity to travel abroad and to get involved with companies such as Dyson, Jaguar, Austin Martin and then even allowed me to watch rockets being built in Russia.
I trained engineers and factory workers in the use of mathematical and physics based subjects. Some of those I taught had jobs which involved predominantly manual skills and so they were a little rusty when applying mathematical techniques. This makes me appreciate the nervousness some adults have when presented with a subject they may not have touched since leaving school.
After leaving the engineering world I had a brief spell working as a trainer in the insurance arena and then finally ended up teaching mathematics in secondary schools.

Teaching Experience:

I worked as a manufacturing engineer for 8 years and then I taught engineers and factory workers for 10 years in the use of techniques involving mathematics and physics. After leaving the engineering world I trained adults to use a mainframe software program and then I went on to become a secondary school mathematics teacher. Finally I started tutoring from home working with various types of pupils. Some pupils have special needs, whilst others are working towards an A grade in their A levels.

Tutoring Approach:

I like to know why the tutee wishes to study. It may be to improve their confidence or to pass an exam. This will then shape the nature of the tutoring sessions. My focus is to provide people with the knowledge that is most useful to them and their aspirations.

Personal Description:
Hiya
My name is Kathryn and I'm currently studying Maths and Physics at Durham University. I am back in Guernsey over the holidays and am available to tutor various subjects at various levels.

Teaching Experience:

I have previously tutored Maths and Physics at AS/A2 level and GCSE level and I have tutored in preparation for 11+ exams. Whilst at Durham I have also attended workshops about tutoring skills held by TeachFirst.

Tutoring Approach:

My approach to tutoring is to be friendly and open so that tutees feel comfortable to ask questions so that the tuition can help to tackle individual issues or difficulties. Also, since I have recently been completed school education I feel I have a good knowledge of current teaching and examination styles.

Personal Description:
I'm a qualified teacher with experience in tutoring students from GCSE to undergraduate level. I received a Physics degree from Cardiff University, before getting married and moving to Sheffield to do my teacher training and a PhD.

Throughout this time I have been involved in teaching and tutoring, whether more formally in schools and at Sheffield University, or more informal private tuition to GCSE students and an engineering undergraduate.

My teaching seeks to develop understanding, whilst being enjoyable, and generally includes practical activities as well as written and oral work. In this respect I have spent many sessions in primary schools, secondary schools and public spaces (including the Winter Gardens, Sheffield) doing public Science teaching, demonstrations and promotions. This has helped me learn how to help everyone understand various aspects of Maths and Science, regardless of background or age.

Outside of teaching and tutoring I enjoy cycling and getting out into the Peak district.

Teaching Experience:

Whilst completing my teacher training I taught students from 12-18 and across the ability spectrum in all three Sciences.

Since then I have been involved in delivering tutorials and lectures at Sheffield University to undergraduate students in Physics and Maths. During this time I have privately tutored both undergraduate and GCSE students.

Tutoring Approach:

I vary my approach to tutoring depending on the needs, ability and age of the student, but in all cases I'm patient, friendly and encouraging.

When there is sufficient time, students are encouraged to complete some diagnostic work to establish both their ability and confidence across the curriculum. This allows the tutorials to be planned appropriately for each specific student.

Just before the exam, exam technique help and troubleshooting can make a significant difference to the students performance and confidence, even with just one or two sessions.

Personal Description:
Hello there!
I am a Mothertongue Italian teacher and actor. I have studied Linguistics and taught English and Spanish in Rome and Italian in the UK. I've also acted for many years on stage & cinema. Acting and teaching are surely what I enjoy the most in life.

Teaching Experience:

I have studied Linguistics at Tor Vergata University in Rome and I've been teaching English and Spanish in Italy and Italian in England for three years now.
Being also an actor and enjoying teaching, I am an acting coach and teacher as well.

Tutoring Approach:

FREE TRIAL! THE FIRST HOUR OF LESSON IS FREE!

First of all, I check my students' level and goals. Starting from there, I am an intense teacher and coach and I give the best that I can at all times, keeping the time we spend together useful and enjoyable for my students.
I have always been very satisfied at the general success of my students, that's probably because I am quite empathic and I always chose my teaching method basing it on my student's personality and will-to-learn.

I am based in Streatham Hill and I tutor at my place or I can travel in the London area.

Personal Description:
Currently i run a small business in which i deliver foot health care services to the community. Recently i graduated from the University of Glasgow with a Masters in Biotechnology (2015) and i have a BSc (Hons) in Natural Sciences from the Open University (2013)

Teaching Experience:

While studying for my degrees I tutored high school students in Biology/Human Biology, with some input from myself and hard work from them they achieved great results and got into the university and course of their choice. Have also been tutoring my own son who struggles with maths skills. While employed by the NHS i worked with semi- pro and amateur athletes who often got injured, part of the treatment plan was to explain why certain exercises aggravated their condition and provide sources for alternatives and give further health education when needed, this mentor/teaching experience was tailored to each individual need.

Tutoring Approach:

Each lesson is tailored to the needs of the individual, will ask questions of the tutee to ensure they have grasped the concept being taught. In subsequent lessons will have a brief revision time to again check that the concepts have been fully understood.

Personal Description:
I am currently training to be a doctor at the University of Manchester. Before embarking on my current endeavour, I completed a BSc (Hons) in Chemistry with Medicinal Chemistry, graduating with a 1st class (I graduated 3rd in the year group).

Teaching Experience:

I have experience of presenting information to others during my degree, which involved presenting complex scientific information in a simple and succinct manner.

Tutoring Approach:

I believe in thorough preparation so I am happy to be sent material/questions that I can review before each session. I believe tuition is the foundation for better study so I aim to read around the topics that I teach in order to be ready to help the student apply their knowledge to academic problems and real-life situations. Getting the highest grade possible involves mastering topics that are difficult which is where I can help. I aim to make learning interesting while helping the tutee get to grips with challenging topics such as hydrogen NMR, redox reactions, Born-Haber cycles, organic reaction mechanisms and pH/pKa calculations, to name a few.

I continue to study chemistry informally in order to keep my knowledge up to date. Currently, I am studying the commercial applications of inorganic chemistry. I have extensive experience in studying all the major branches of chemistry: physical, organic and inorganic chemistry.

Personal Description:
I hold a full-scholarship academic PhD in English Drama and an MFA with Distinction in Shakespeare from the University of Exeter, as well as a first Class BA in Theatre from the University of British Columbia. I have published scholarly articles. Additionally, I have received relevant certifications in Teaching English as a Second Language and in radio presenting (and a slightly less relevant one in stage combat!).

I am a professional actor with experience in all media including the West End, and am a founding member of Hotspur Theatre Company. Additionally, I have professional experience as a playwright, theatre director, and teacher.

Teaching Experience:

From nursery school students to 16-18-year-olds, and undergraduates at the Universities of Exeter, Bath Spa, and Cumbria to postgraduates at the LAMDA drama school, I have taught students at almost every level. I have also coached adult professionals.

My key tutoring subjects are English, Drama, Shakespeare, English as a Foreign Language, Elocution, Voice and Speech, Public Speaking, Acting, and Research and Academic Writing. I look forward to helping you to achieve your best results!

Tutoring Approach:

All students are different, and therefore I vary my approach student-to-student. That said, my core approach includes my experience in drama, and I will often use play scripts as texts to analyse, or for language-building exercises and conversational scenarios. I have a substantial research and essay-writing background as well, so can offer useful insights into students' written work.

Personal Description:
I am an enthusiastic Spanish Tutor with a passion for teaching at all levels and I am committed to safeguarding and promoting the welfare of children and young people. As a native Spanish speaker, I am oriented to cultural diversity, world history, high professional standards and good planning.

Teaching Experience:

Currently, I am working part-time at Scarborough Sixth Form College as a Spanish Language Assistant (AS/A2) and Spanish Tutor (Lifelong Learning/Beginners) since 2015. Through this, I have gained valuable experience of working with young people and adults by employing strategies for differentiation in teaching and learning, as well as by adopting a creative and imaginative approach to developing resources.

In addition, during this period of time, I have been building up my experience in Private Spanish Tuition since 2014 by working with students towards basic, intermediate and advanced proficiency in the Spanish Language, including the use of the GCSE framework.

Tutoring Approach:

During lessons and conversation sessions I employ strategies that help to improve students confidence in communication by encouraging them to speak naturally and using body language (facial gestures) as well as tone of voice properly, as this is an important part of the culture in Spanish speaking countries; Also I always motivate them to continue studying languages by remarking the advantages of this for their professional and personal future. I do believe that the key to being successful in this is to reinforce the strengths of students rather than just focus on their weaknesses and the fact that every student deserves attention as well as a fair treatment according to their needs.
