Experience

Parents and students
Hi

One to one tuition is conveniently held at students own home at a mutually agreed time and day (weekends and weekdays are available)so parents avoid spending the time and hassle of driving and delivering student to and from tuition held at coaching centre...often after hard day at work.

For year 7 - 12 students fee based on $60/ hour at students home or public library
The first lesson only is discounted to half the above rates....($30/hour ) ..but this is only if you mention this
this site.

Advance payments not required.

No contracts to sign and therefore parents not locked into paying for unsatisfactory tuition for months in advance

Students should prepare a list of questions and concepts causing difficulty to be discussed during
tuition...this will enable me to determine the students academic level and plan an appropriate program of learning.

Tuition is more effective in terms of learning and obtaining maximium improvement at minimum cost if done on a one to one basis rather then tutoring several students of differing abilities and different ages and school years at same time in a group.Student does not have to wait for question to be answered.

One and half hours tuition for a group of three students at a time implies that each student receives approximately 30 minutes of one to one tuition .This is in general insufficient to cover background and understand the scope and depth of various topics.My group size consists of one student only...this has obvious advantages.

My tuition is personal as possible as there is only one person in the group and the style of tuition is tailored to suit the learning style of the student ,to explain how to obtain correct answer to school and exam problems and other relevent questions.

As there are no other students present , the student need not feel embarassed asking questions. By the way if a students asks many questions there is no increase in fees...if a students asks very few questions there is no decrease in fees. Students often feel inhibited and embarassed about asking question....in my view the only bad question is the
one which is not asked.

My emphasis is to explain the fundamental concepts in mathematics and physics in simple terms and ideas and whenever reasonably possible use existing fundamental laws to deduce more laws equations and rules.When students understand they begin to learn and enjoy the subject. It is difficult if not impossible to enjoy a subject which is only partially understood.It is more interesting and challenging to derive an equation rather then receive it without background explanation and derivations.

I have also prepared some Mathematics / Physics experiments and there is excellent agreement between measured and predicted value.

Experiments in Mathematics help students bridge the gap between theory and practise and better able to understand the more abstract theories eg Simpsons rule...integration and Simpsons and Trapezoidal rule to find area...Newtons law of cooling...maximum and minimum turning points.

For physics the following experiments are available:
potential and kinetic energy...parabolic motion...period of normal pendulum and conical pendulum.measurement of earths gravity...conservation of momentum for elastic and inelastic experiments
. ..Galileos experiment. etc..how to calculate
radius and mass of earth using three simple measurements and Newtons Law of Universal Gravitation, Lenzs Law . A good quality accurate experiment is a very effective learning tool and a means to better understand fundamental concepts.

Please note that Year 11 students will follow the new revised Physics syllabus starting this year (2018)
which is far more difficult and of higher standard then the previous syllabus. It is far more appropriate in terms of scope depth and choice of subject matter.for students wishing to study Engineering/ Science at University. .


Homework is given at the end of each tuition session and is based on what has been taught in tuition and at school.
All steps needed to find solution should be written legibly in clear logical order.
Students should study written examples and explanations given in tuition before attempting homework which should be attempted as soon as possible after tuiition This should preferably be completed no later then 4 days after tuition ( while concepts taught in tuition are still fresh in the mind of student)
Students should not spend too much time correcting a solution if the answer is wrong as this can be frustrating and demoralizing The attempted incorrect solution should not be rubbed out.. It is better to let me find the source of error which in many cases is a very simple mistake.

All homework should be written into an A4 sized notebooks . These must be kept as a record of topics covered and the
scope and depth of coverage.A summary book will be developed by the student which will incude formulas examples and an index of topics.
A seprate smaller note book containing index and summary of topics as written by student immeditely after successfully answering homework questions.These contain formula and examples and a list of common mistakes to avoid.It also contains a section of common mistakes to be avoided.

_____________________________________________

22/9/17
The following questions are both unusual
and more difficult then those found in a
normal textbook.

1) How to find the value of e from first principles

Must first understand the concept of e

given that f(x)= B ( power x)

Does there exist a value of B such that

df/dx = B (power x)

(Unchanged by differentiation) and if so find its value

Using the fundamental definition of differentiation

(f(x+h) - f(x))/h= ( B (power (x+h)) - B (power x))/h


B (power x)= B(power x)(B (power h) -1)/h

1 =( B(power h ) -1) / h
Rearranging

h + 1 = B (power h)


Log (h+1) = h Log B (must use base 10 ..why)

B = 10 power(Log(h+1)/h )

Let h equal a very small number eg 0.000001


B = 10 (power( (Log 1.000001)/0.000001)

B = 10 power 0.4329

B= 2.718 (approximately value of e)

I would appreciate any feedback on this derivation...whether you agree or disagree
