DAY 1: 25 May

Type a 100-word reflection for today's lesson.


Although tedious and challenging, I find this lesson quite interesting. As we explore deeper into this topic, we have moved on from finding equation of lines and quadratic graphs to finding the distance and mid-point through Pythagoras Theorem, which will then be followed by Trigonometry. This topic is very important as it encompasses many other important concepts that are vital in the future. Having a strong foundation in these concepts is crucial to score well in the later years as we will find it easy to move on to more difficult and challenging questions. However, I must admit I feel that the whole of this topic is quite challenging as compared to others. Although finding the distance and mid-points of lines is relatively easy now, I believe these concepts will be needed to be applied in other areas too. This is another great experience for me as I am able to learn the topic at my own pace and at a totally different environment from school. This change is indeed refreshing and conducive for learning. In all, I feel that finding the distance and mid-points of lines is relatively easy if you are able to grasp the concept behind it, but I believe harder things which require these concepts will come out again in the near future.


DAY 2: 26 May

Type a 100-word reflection for today's lesson and comment on your work.

It was quite time consuming and challenging as I had to spend time to familiarize myself with the different functions of the graphic calculator to obtain the desired picture. I made many mistakes when using the calculator to draw circles and had to research to find out more about it. However, I felt a sense of accomplishment after completing the picture. I feel that this is a very enriching learning experience for me as I can work at my own pace and figure out and discover new things by my own, thus making me more independent in my learning. In all, I feel that today’s lesson was interesting as I learnt how to find the equation of circles. However, I am still not very confident in this topic and need more time to learn and practice.
