Youtube helps students to do maths

I read with interest on this article (taken from Digital Life Singapore).

Nicole, the student mentioned that she can learn at her own pace anytime, anywhere. And if there are any concepts she wasn't clear, she was able to rewind and replay till she understood what they were all about.

With the advancement of technology, learning can be so accessible and it's all for free and most importantly, learning is only through medium which is likeable and popular with the students.

singaporeolevelmaths.com has been using videos for teaching tools as well and I am going to introduce more videos in 2009 as part of adding value to all our readers. So keep a lookout for these videos which will absolutely help you in your Mastery of your 'O' level Math. Here are some of the previous videos:

2009 Ultimate Leap Programme : Weekly Ongoing Coaching Classes for 'O' level A-Math

See Results EVERY Lesson!

Thank for being my reader and for always reading my blog post.

It means a lot to me and I hope I have been useful in one way or

another towards the mastery of your Math.

As we move towards 2009, I look forward in providing more

value to you.

For Singapore students, here's a surprise for you:

I will be personally coaching a group of students

(Sec 3 & 4 students) to help them achieve the results they

truly deserve for 2009.

But there's a problem...

My training room cannot sit many,so I can take in only

a handful and out of these, some seats have already

been taken up by my workshop participants.

So, if you are really committed to achieve your 'O'

level A-Math distinctions, read about how you can

get what you want HERE

Cheers,

Work Hard, Play Hard

I made a trip to Genting Highland last week as a short getaway from the hot weather in Singapore. Here are some of the highlights. Personally I think that the power tower is well taken, don't you think so?

I guess many of you have also travelled overseas during this holiday to recharge and be ready for year 2009! Another exciting year ahead!

Share with me in the comments section where you travelled to and perhaps a photo or so to sum up the highlight of your trip would be awesome!

O level A-Math Essential Concepts Workshop Student's Feedback [Including Parent's Comment]

Dear Ms. Ling,
Thank you so much for the photos and looking forward to the work she has done for the past 4 days.
I'm very contented that she has learnt alot from this workshop and my money is worth it. Appreciate you help in motivating and making A-Maths a joyful and interesting workshop for my kid.
Tks, Shoba (Parent of Devyaah)

“I have benefitted a lot from this workshop. Ai Ling has put across alot of different and creative ways to make us understand the complex concepts in A-Maths and make it easier to remember the various formulas. I haven't been getting good results in my school exams but through this workshop, I had learnt the common mistakes I always make and had understood the concepts better. I will really recommend the workshop to my classmates as I think it has been really beneficial for me. Thank You (=”

“Very good, I understand the concepts better and know how to apply the formulae. I have improved and am happy about it. This programme focuses on the key concepts.”
Bryanesh Balu, Yuan Ching Sec Sch

“I like this workshop very much, I really learnt alot!! I like the way you teach I can understand easily, the story makes us remember the most and all the different types of methods you used to teach us I love them. I will remember it forever. The music make me feel like the environment is good for learning and it prevented me from getting too stressed up. I like the way you help me to recap yesterday's things and your method of teaching us is so special. Thank you!!"

Jonas Tan, Regent Sec Sch

“I came into this course thinking that I wouldn't learn much but I was wrong. I've learnt alot more than I imagined I could in four days. I would definitely recommend this to others. I have learnt a great deal and it definitely has helped me a lot. I've not been for other programmes so I wouldn't know how to compare but this definitely is one to remember. Thank you for the assistance you have given me for the past 4 days. I'll continue to look at A-Math in a new perspective. Thank you for your 100% attention towards us to improve our A-Math”

O level A-Math: Fatal Mistake In Logarithm Equation You Must Aviod

This is a common mistake I notice in my O level A-Math essential concepts revision workshop.

Solve the following equation:

First, you must identify the type of question since different types of question require different strategies.
It's a different log-log question.
Strategy required: Change base.

Change base formula used.
Reason for changing to base 2: Between changing to base 2 or x, we choose base 2 as x is an unknown, we choose not to work with THE unknown most of the time, don't we?

Since we observe that there is a common term (log2 x),

Did you observe the fatal mistake (It's #7 Common mistake in Logarithm?

The correct way to do the substitution would be:

Solve the quadratic equation for y. Substitute the value back to find x.

Remember to check for validity of answers.

O Level A-Math: Fatal Mistake In Quadratic Equations You Must Avoid [Includes the 'trap' & How to avoid it]

This was one of the tricky questions included in quadratic questions pre review (I begin every A-Math lesson with pre review so that students can 'show off' their level of understanding in the concepts we're going to discuss. And as I guess it, everyone falls into the 'trap'

Reasons for students falling into the 'trap'

" .... is always positive, oh b^2 - 4ac >0"
" for all real values of x, so it further supports the fact that b^2 - 4ac >0"

How to avoid falling into the trap

Understand the question clearly

" It is THE quadratic graph which is always positive "
For all real values of x is NOT equal to real roots, it just means for all values of x. (No much significance in our solution)

Structure your solution carefully

Draw (A picture says a thousand words)
Write down the 2 conclusions
List your a,b and c
Solve the inequality
