My name is Chiu Tuen Ming Dicky and I am a secondary teacher in a catholic boy’s school. I teach F3-5 mathematics and A. Maths.. Actually, I love my teaching very much and I think that teaching is meaningful. I not only teach students knowledge but also influence their growth positively. Meanwhile, I can develop the friendship with students and this kind of satisfaction can’t be got in many other professions.

My feeling about the final assignment

First, I am not familiar with the software Flash and I found it's really difficult to get started. Bit by bit, we could finish the program at the end.
Second, though I am a mathematics teacher, I find the program very interactive and it can arouse the students' learning motivation.
I think I will pass my final assignment to my colleagues to try it....

My final assignment

Most S.4 Chemistry Students do not know why the end point of an acid-base titration (e.g. colour change of the indicator) can roughly match the equivalence point of the titration. From the following learning object, it shows when various amount of hydrochloric acid(acid) is added into sodium hydroxide solution (base), the pH of the reaction mixture (indicated by the titration curve) and colour of the indicator (in this case : methyl orange) at each particular moment. The visual representation can make the case explicitly visualize to the students.
