Task 1
In most text books or reference books, the explanation for radioactive decay is : caused by its unstable nucleus. After the nucleus emits radiation, a stable nucleus is formed. What actually causes a nucleus to be unstable is not explained in these books.
In my lesson, I served the internet to get information about why a nucleus is unstable before it emits radiation. Then, the information is presented using PowerPoint.
It is actually caused by the attractive force and repulsive force acted on the protons and neutrons in a nucleus. These 2 forces reveal a tug-of-war in the nucleus. When the term tug-of-war is used, ‘wows and ohs’ are heard which means the students understood and they found it interesting – something which they can’t get from books.
From this lesson, I realized that teachers can actually prepare something extra than what the students should learn to help them to understand more and sometimes to make the lesson more interesting. Usually teachers do not teach what is not in the syllabus, because they feel is unnecessary and is a waste of time.
To improve this lesson, I can call a few students to act as the protons and neutrons. Besides that, they experience the forces of tug-of-war and the situation will be more alive and hands-on.
Task 2
That was the second year of my teaching life. I was given a Form 4 arts stream class as their science teacher. This girl wasn’t paying attention and didn’t do her homework to pass up. I told her to stand but she refused, after a few times, she stood up with a leg on the floor and the other on her chair and shouted at me because I bother her. Of course, my lesson was not carried out. She was brought to the discipline teacher and also the counseling teacher. At last, her mum was called to the school, she actually came from a broken family. The girl was sitting on a chair and the mum stood behind her when they were talking to the PK HEM (She dared to raise her voice when she talked to her mum and the mum has to do what she says). At last, the girl was expelled from school. From this experience, I feel home education is more important than school education.

Hi Evelyn,
Am very glad to read your interesting story! Thanks Evelyn! It's good to know how proactive you were in your teaching .. especially knowing that your curiosity has drawn you to make your own 'research' in order to find information that was not explained in the text book.
Task 2 -> I believe that almost everywhere, teachers are facing with such kind of situation (rebellious students, problematic etc). The case that you brought here was one of thousands of other stories.
Would you share with us, what was your unpleasant experience that you underwent during your teaching years - the lesson that did not turn out well as what you planned before and what were the factors that you think made it unsuccessful?
Looking forward to read more about it :)
Thanks!
Yes, Evelyn has shared an interesting experience in her career. What about the others.... you may share your experiences too
Hi all, Have been a silent observer. Interesting story Evelyn about the rebelious child. Guess home upbringing is very important. Anybody has a similar experience and more effective way of handling it?
Hi group members
Can you please send a photo to Fariza so she can put it up. Would be nice to see some faces : )sm
Evelyn, a very creative way of simplifying a complex structure which I guess met the objectives of the lesson judging from the excited response of your students. Congratulations! You must be a great teacher that students admire. Keep up the good work.
Hi Evelyn,
It is interesting. Your suggestion to do the simulation ( the force of tug-of war )interesting too. I can use the idea to teach my students.
Congratulation! You succeeded to teach your students very well.
For Task 2:
I am facing that problem too. Some of my students ( especially boys ) always make trouble. We have to use different methods to handle the different students.
Sometimes, they have problems at home. It is good if we can study their background. It will help us to know and handle them better.
Hopefully, you can tolerate with them.
....I remember teaching a very weak class way, way back and i remember spending so much time shouting at them that I had hardly any time to teach... so does anyone have any ideas on how to handle naughty boys? : )
