Sec 4 Physics Reflections 03/02/13 – Current Electricity

Posted on February 5, 2013February 24, 2016 by admin

Today, I asked them a few questions to improve their conceptual understanding of electricity:

(1) What is the difference between e.m.f and potential difference?

(2) What is the difference between resistance and resistivity?

(3) How do you derive the unit for resistivity?

(4) Why does the resistance of a metallic conductor increase when its temperature increases?

(5) Why is the ammeter connected in series to a resistor but the voltmeter is connected in parallel?

Some points to note:

(1) Resistance is NOT the gradient of the V-I graph.

(2) The I-V and V-I graphs of a conductor may be different and you’ll need to understand why and explain the difference.

Sec 4 A. Math Reflections 02/02/13 – Higher Derivative

Posted on February 5, 2013February 24, 2016 by admin

Today I taught them the Higher Derivatives, using displacement, velocity and acceleration as real-life examples. I chose not to introduce the 2nd derivative as a means to test whether a turning point is a maximum or minimum, as I preferred to do that when teaching the application of differentiation in tangents and normals at a point in a curve.

Points to note:

(1) students must not write the 2nd derivative as dy^2/dx^2;

(2) d^2y/dx^2 is not the same as (dy/dx)^2;

(3) d^2y/dx^2 is the same as f”(x) or f^2(x);

(4) there may be product rule, quotient rule or chain rule involved when finding the higher derivatives.

Ilyasa, M.Ed, PGDE, ex-MOE Math and Physics teacher (hp: 97860411)

Sec 4 Physics Reflections 27/01/13 – Applications of Electrostatics

Posted on January 29, 2013February 22, 2016 by admin

I wanted to proceed to Current Electricity, but the students wanted more discussion on how to answer application questions on electrostatics.

So I supplied them with quite a number of such application questions, often with confusing diagrams. The key to answering such questions is to first draw the distribution of charges on the items in the diagram, and identify which objects are conductors and which are non-conductors. For the conductors, check whether they are insulated from the surroundings.

Key points to note:

(1) Only non-conductors can be charged by rubbing (why?)

(2) Electrons can flow into and out of only conductors, and only when the conductors are in contact with other conductors (why?)

(3) A charged object can attract a neutral conductor (why?) and a charged object can also attract a neutral non-conductor (why?)

(4) Upon contact with a highly charged object, a conductor behaves differently from a non-conductor (why?)

Sec 4 Physics Reflections sun1415 20/01/2013 – Electrostatics

Posted on January 21, 2013February 22, 2016 by admin

I completed the teaching of Electrostatics to this class of 6 eager boys from a top school. First I showed a video of how a home-made electroscope is used to determine the kind of charge on a rubbed insulator.

I like to link topics to real life, so I described to them one of my roles while serving NS – to attach cargo to the bottom of a helicopter in what is commonly known as “underslung” operations. But we have to discharge the helicopter first, which is flying above our heads, using a long earth wire, else we may get an electric shock.

We covered definitions, procedures and concepts such as electric field and electric field lines. I even taught them an A-Level formula, F = Qq/kr^2, so that they understand that the electric force between two charged particles is the same for both charges even though the sizes of the charge on them are different.

We also discussed answers to a challenging worksheet and true enough, the students have certain misconceptions about charges and their movement.

Next week, we’ll start on Current Electricity. It’ll be fun.

Sec 4 A. Math Reflections sat1415 19/01/2013 – Differentiation

Posted on January 21, 2013February 22, 2016 by admin

This was our third lesson in Jan. We did the Product Rule for Differentiation after spending the last two sessions doing the Basic Rule and the Power Rule (a subset of the chain rule).

I told students to differentiate directly, in line, and not use the “let u = f(x) and v = g(x)” which is longer, more confusing and can cause more careless mistakes.

Now they are able to perform dy/dx = f(x)g'(x) + g(x)f'(x) quite quickly without introducing new variables such u and v which can be quite clumsy. Most of the time, finding dy/dx is part of a larger question, so it is unwise to make this part too long.

I ended the lesson with an intro to the Quotient Rule. Again, I don’t recommend the use of u’s and v’s and instead differentiate directly in line. We’ll be practising the Quotient Rule in the next session.

Again I tell students that Calculus is almost one-third of the A. Math syllabus, so if you want to get A1 you have to master Differentiation and Integration, which, in my opinion (and students hate it every time I say it), are amongst the easiest of topics in A.Math.

However, Integration at the A-Levels (H2 Math) can be quite difficult. But we’ll cross the bridge when we come to it. : )

Just finished Sec 4 IP Math and Physics tuition…

Posted on February 26, 2012February 13, 2016 by admin

Sunday mornings are very tiring for me – 2 hrs of Sec 4 IP Math followed by 1.5 hrs of Sec 4 Pure Physics tutoring. The topics we are doing now are Trigonometry, Differentiation and DC Circuits.

Apparently, some schools are slower than others. Sec 4 students should now already be doing Differentiation and DC Circuits, but some are still at graphs of trigonometrical functions and electrostatics or even sound!

Every year, my tuition students who are weak in Math come from two ‘very good’ schools in the west. I shall not name the schools but I think the lower sec Math teachers in these schools need to get closer supervision from their superiors. This is what I have been trying to tell parents – ‘good’ schools do not necessarily have good teachers. Some of these schools attain good results because their students are academically good in the first place, not because they have outstanding teachers. If you enter a ‘good’ school, chances are, the teachers there think you are already very smart, so they teach fast and make you do a lot of ‘independent’ learning, and justifying these actions using the ‘Teach Less Learn More’ philosophy.

Last but not least, I’ve said this before and I’ll say it again: SEC 2 MATH IS VERY IMPORTANT, ESPECIALLY THE ALGEBRA PART.
