Electromagnetic induction notes

Ok, this is the last I'm sharing for today. This one is quite an important bit for physics. It's the pesky last chapter for the current physics syllabus - electromagnetic induction. I did this years ago, and thought that it's still very useful for present usage. Damn, should have issued this instead of having to write ALL of them out during my class. What a splendid time saver...zzz...

Here it is -
electromagnetic induction notes.

Pure physics checklist

Since i'm at the mood of sharing my worksheets / notes, here's another one I did years ago, when I was more free to do such things.

This one is the physics checklist for O'lvls. I included all the things that you need to know about physics pure syllabus. This is a bit old, so parts of 23 (those logic gates) and the entire chapters for 24 and 25 are out of syllabus.

How to use this checklist?

1. First, read the checklist

2. Read the textbooks/notes, paying close attention to those that are listed in the checklist

3. After finishing one chapter, read the checklist and ask yourself if you can answer those checklist. You really need to know those stuff in the checklist.

4. If there are some knowledge gaps, go and read up those specific parts again.

5. Repeat 2 to 4 until you know all the stuff then move on to the next chapter and repeat.

Quadratic equation worksheet

I typed out some worksheets on quadratic equation problem sums from an old assessment book that I bought years ago. It's those problems sums where you have to form your own equation, and then solve the equation in terms of x. My student had some problems forming the equations (which is basically the hardest part of the problem - solving them is easily done), hence I set this up to help her.

Here's the link for those interested.

Mother Tongue results out

Yesterday, my students got their mother tongue (MT) results. Most didn't do very well, and I wonder why. Are we no longer focused on MT? I guess I'm slightly different, as I speak MT at home, rather than English, hence English is more acquired for me than my second language.

I pity those who had to retake again, it's just a bloody waste of time. I can imagine how painful it is. Though last time in my O'lvls, I managed to do it in one trial (A2 - dun play a fool with me), I did tried two times in my A'lvl. That took up a lot of time and I could have spent it on better things.

Come to think of it, not a lot of my students can make it in MT. I can only vaguely remember a handful (less than 10) whose MT is as good as their English. Most are just passing standard only. So much to say about Singapore's bilingual system - it seems that it made that effectively single language only.

H1N1

The recent outbreak of H1N1 is causing a lot of problems in Singapore. Me, especially. When the last pandemic of such scale happened, it was during the SARS period while I was in NUS. I wasn't acutely aware of the implications, just that I must not go around crowded places and so on. Basically, I couldn't care less.

But for this current pandemic, my job was affected. As Singapore nears the peak of cases reported with H1N1 (coupled with 5 deaths so far), there are many many students reporting fever and even 1 confirmed case of H1N1. Quite a few cancelled because of flu-like symptons coupled with fever. What can I say? Of course they had to rest and cancel the tuition.

It's been pretty disruptive to my job and schedule. Hopefully all these will clear up soon and things will get back to normal.

Going to meet my H1N1 student this afternoon. Wish me luck!

Wordle

This is such a nice picture, I have to share this! There is this website where you can create wordle. Don't know what a wordle is? You just have to try it to see it, amazing!

Progress on my book

Here's the update for my new book. I've began writing since last week and making some good progress. Already, I've had 160 questions under my wings, and it's only 50% done. Looks like I should be able to finish a chapter at long last!

I plan to finish a chapter every week, so I should be able to finish in around 6 months or so, provided I keep to my schedule. It's a bit hard to think of questions but the worst is actually having to type it out as it takes up a lot of time. No choice lah, have to do it anyway.

For the sake of my students, I must persevere!!
