“Tell me and I forget. Show me and I remember. Involve me and I understand” – Chinese Proverb

The secret in the mastery of ANY subject is for Understand + Involve.

It is called experiential learning :-)

It was reported recently that there are more and more kids who are being home schooled by parents.

Home Schooling has been a concept which is widely prevalent in US and now the trend is catching up fast with Singapore. With higher education level of parents, parents are fully equipped to coach their children at home with their own curriculum.

In my own opinions, these are the advantages of home-schooling

  • Children can learn at their own pace and their own style instead of following the general speed of the education system and the classroom-whiteboard teaching style. By allowing learning at own pace, they tend to enjoy more and learn more effectively in the process.
  • There is total freedom & creativity in the way parents or coaches can carry out the way they teach. For example, a science lesson can be carried out in the park in the form of a treasure hunt. Environment plays an important role in the learning process. If it is fun, children will love it and this helps them to build their learning thirst and the desire to explore more.
  • Stronger Parents-Children bonding is established through fun and play instead of the conventional sense of authoritative figure. This is especially crucial with society moving into the information technology where things are porgressing at such fast pace that we overlook important aspects of life like relationship. Home Schooling allows the time for close interaction between parents and children which definitely is beneficial in the growing up phase for children. (more…)

[Mathematical Proof] Girls Are Evil

Now I am showing this in the name of fun.

Girls take no offence ;-).

This example illustrates the use of equation, squaring, taking squaring roots and the interpretation of English to Mathematics. All important components of Mathematics.

Hope you have fun.

What is Linear Law?

It is a tool which will allow you to transform non-straight line equation to straight line equation so that you can plot a straight line. Most of the time, the axis will consist of x and/or y

One of the techniques involving taking lg (log base 10) on both sides of the given equation.

Common Mistake! STOP
y=Ax^b=>lgy=blgAx=>blgA+blgx

This is one of the common mistakes I have highlighted in Top 7 Commonly Made Mistakes in Logarithm

How To Counter This Mistake

Very simple. Just add in a bracket on the right hand side of the equation.
y=(Ax^b)<br>  =>lgy=lg(Ax^b)<br>  => lgy=lgA+lgx^b<br>  => lgy=lgA+blgx<br>

Now, your y-axis will be lg y and x-axis will be lg x. Gradient = b and y-intercept = lg A
