Methods of Memorising

As much as I (and I am sure many of us) hate memorising, it is inevitable in school that we need to reserve part of our brain for memory work. At a young age, we need to memorise how to spell words. As we grow older, we need to memorise F=ma, p=mv etc etc... Now let's ask ourselves, are these so-called memorising really memorising? Many times, certain things just come to us and I doubt that we will ever forget them cleanly. In this post, I am going to share how I commit knowledge to memory (in addition to using mind maps or time lines), because I hate memorising!

Form words and short sentences of meanings to you.
When it comes to really memorising, there are many methods taught. One of which is to use short forms or abbreviations. In marketing, we learn the 4P. We then recall it stands for product, price, place, promotion. Isn't this easier than to purely memorise each of them? In electrical engineering, we tend to forget the relative phase lead/lag of capacitor or inductor. But we have "CIVIL" to help us! Form your own sentences, use them!

Practice more, use more.
One way of memorising is to practice. You may not remember how to integrate log(x). Try doing it 3 times. I'm sure it just comes to you the next time you are asked. You may not know how to use the product rule to do differentiation. Use the technique on 5 different questions. You will just use it naturally when you reach the sixth question.

Write
This is a trick taught to me by my cousin Linda. I remember I was in secondary 3 when I needed to memorise facts about the Cold War. I had a hard time doing that because I was simply lazy to memorise and my memory was (is now too) very bad. She came to me with this trick. Here, she meant writing using pen and paper. Do not type, do not read and form the image in your mind. Write! I found that it works. As I write, I think. As I write, I see my own paragraphs. When I need the information, I just have to close my eyes and the image of what I have written appears. Sounds magical? Try it.


Memorise only when needed, as a last resort

I only memorise stuff when I don't understand them, because that's the only way I can get past examination without getting zero. Hence, I always seek to understand the topic, seek to understand the equations, understand how each concept is being used. And here I repeat again, understanding the basics is very important. When we understand, there is no need to memorise. If you forget the formula for acceleration, think of what is acceleration. If you understand acceleration as the rate of change of velocity, the formula will come to you naturally. When we understand what is nation building, there is no need to memorise how Singapore grows from practically nothing to what we are today; and hard facts like economy, social, politics. These will naturally come to us.

There are many well known methods to do memory work. However, it is up to us on whether we just want to memorise, which most of the time we will definitely forget right after the examination, or we want to understand the topic proper. The latter does not only allow us to understand what we are studying, it also allows us to store the knowledge in our brain for a longer period of time. My personal opinion is to try our best to know the topic, because knowledge is king.

My Way of Learning: Understand And Master The Basics

How many of us forget how to do integration the moment we step out of the exam hall? How many of us give back at least 50% of what we have learned to the teacher the moment the chief invigilator announces "Pen Down!"? I realise that this is the case with many of my friends, myself included. Why does this happen to us, including those who can score well in the paper?

Understand The Theory

understand the basics

From what I observe, this problem arises from the way we learn, from the way we go about picking up a new knowledge. I understand from my tutees that in school, they are being taught a new topic via examples. For example, instead of learning what is integration, or just a simple explanation of it, they are just told to memorise the basic formulae of integration and apply them accordingly. This greatly restricts a person's ability to apply the knowledge on the same question phrased differently.
My take is to learn the basics, learn why it happens this way. If the theory behind a particular knowledge is too high level for students of, say, 15 years old, talk simple. You may want to refer to my post on Effective TeachingFor learners, please do not get too involved in solving one question and feel lousy if you can't solve it. Go back, read the theory and understand why things happen this way, then come back to tackle the problem again.

Practise Practise And Practise

Practice Makes Perfect


Yes we know this. We have been following this ritual. This is very important. Lectures teach you, tutorials test you. It is only through practising that we are able to gauge how much do we understand. I remember my cousin Sis HC forced me (she needed to force because I was plain lazy) to finish up all the calculus questions in my secondary school Additional Mathematics textbook. I grumbled but listened. She wanted me to put into use what I have learned. From there, she was able to gauge my weaknesses and went through with me again on the areas I was not sure.
So, do more practices and test yourself before the real test from your school!

1 Tip on Practising
Ask any of my tutees and you will know that I always tell them to do multiple-choice questions (MCQs). My instruction is "finish all MCQs you can find!". My reason is very simple. MCQs, in my opinion, test at least 90%, if not 100%, of the theories. If you are able to score full marks for MCQs, without guessing of course, I dare to say that you have a good grasp of what you need to know.

Finally, I got a phrase from this video http://www.youtube.com/watch?v=_uQjGz6jp2E
If I was doing what everyone else was doing, I was probably doing it wrong
So, do something different now! Try this method if you find that yours doesn't work well. No harm giving it a try. You never know if you never try!
