Two column problem solving strategy is a very effective way in solving challenging mathematical problem. In my past learning experience, I did have a similar approach but not as informative and critical as the two column one. In my high school and undergraduate years, I like to analyse the given information, then see whether there is a connection between the given information and the question, furthermore, I also like to divide the problem into multiple smaller and simpler problems. So I can attack each of the smaller and simpler part of the problem, and then put them together.
I don’t have a name for the strategy that I have been used , however, after trying the two column, I was so surprised about that how much instant feedback I got by constantly write down and looking back my own thought. I also was amazed by the way I was constantly been pulling back to the right track. From the experience of solving the Jacobean Locks, I recognise that how powerful this method can be in solving mathematical problem. I will certainly introduce it to my future mathematic classroom.
