Term 2 - Sexual Reproduction in Humans

Issues in teaching and Learning Science
This was one of the most memorable topic we learnt this year. Sexual reproduction at home was mostly taboo, and what our primary school taught us did not answer all of our questions. Plus, the teacher still felt that we are not mature enough or something, and did not allow us to discuss too much. The discussion with Ms Nada was one of the most active one, and I can see that everyone was very focused and asked many of their burning questions which they previously had to bury into their hearts. We laughed a lot at all of the funny things about sex, because they were very absurd, like how once in a blue moon a baby may be born with both male and female sexual organs, and how sometimes during sexual intercourse a woman's vagina may contract so much that the male's penis cannot be taken out and they have to go to see a doctor to resolve the issue. These kind of funny facts were the kind of things that made the lesson very memorable, not really what the curriculum wants us to learn. But in another sense, that is learning out of the book, isn't it?


Reflections on termly personal performance and growth development in Science


I have always had an impression that the sexual education was hidden in this chapter. We were taught that having sex below the age of consent will lead to many undesirable consequences such as abortion, humiliation, a sense of guilt etc. We also learnt about the menstrual cycle, something very alien to us, but yet very useful too because we will be able to track when a woman is most fertile.
Reflections on science experiences, laboratory sessions,  field work and excursions
My class was joking that we might have practicals for this. Turned out disappointed. We had to research and learn on sexual transmitted diseases on our own, and I realised that it was extremely easy for sexual transmitted diseases to infect the whole community, if we don't practice safe sex. How did our ancestors then, survive? Condoms were not invented until recently, and since everyone a long time ago did not practice safe sex with condoms or diaphragms, how come a large percentage of our population is not infected by AIDS? I researched and found out that AIDS only started spreading from animals to humans in the 1940s. It was fortunate that by then, that technological advances made it possible for condoms to be invented.


Self directed and independent research learning – critical reviews of contemporary science issues

For this module, our independent online learning is on sexually transmitted diseases. Being infected by a sexually transmitted disease just takes a moment of mistake, but the consequences that you must bear you will need to carry it for a lifetime. It is sad how many teenager's lives were destroyed because they were not informed of sexually transmitted diseases or just because they cannot control themselves.
