S1 (Viva Voce) Part A Question 1




S1 (Viva Voce) Part B Reflection

Challenges and Learning Points:
I realised that being a "teacher" was not easy, i struggled to find the appropriate phrase or terminology. It was easy to solve the question but explaining was a different story. I found out i knew how to do it but not why. In my mind it said it's just this, it's right. I couldn't find a proper explanation until i thought deeper and pondered why was it like that. In the end, i managed to come out with a rough explanation to why was it like that and provided some examples. The main challenges i faced was why to change the sign of the term when u shift it over to the other side and the conversion from cm^2 to m^2. Through this activity, i have learned not just how to solve the problem, but also why is it like that, its not just memorising the formula but also to understand it. Another challenge would be how to actually present the working of the Viva Voce clearly as if i had wrote on paper it would have been hard to see, in the end i decided to do a screen-recording of the solution on keynote, as it would show the working clearly and also be able to hear my voice explanation at the same time.

  2. Part (i): You have explained clearly how the equation is derived (opposite sides are equal). In the solving of equation, you've not quite explain "how" and "why" you "moved" the terms (i.e. balancing).

    Part (ii): You have described clearly how you would substitute the value of x to find the numerical values into the respective expressions.

    Instead of "centimetre square", "cm^2" should be read as "square centimetre".

    Part (iii): The conversion, with the basis that 100cm=1cm, is clearly explained.
