## Angular velocity

This GeoGebra app shows how angular velocity ω is the rate of change of angular displacement (i.e. $\omega=\dfrac{\theta}{t}$) and is dependent on the speed and radius of the object in circular motion (i.e. $v=r\omega$). Students can explore the relationships by… Continue Reading

## Angular displacement

This GeoGebra app shows the relationship s = rθ. One activity I get students can do is to look at the value of θ when the arc length s is equal to the radius r. This would give the definition… Continue Reading

## Creating a simple interactive using GeoGebra

While preparing to share with some fellow teachers in Singapore about the use of GeoGebra in Physics, I came up with a set of simple instructions to create an interactive, while introducing tools such as sliders, checkboxes (along with boolean… Continue Reading

## Forces on a ladder on a wall

A ladder rests on rough ground and leans against a rough wall. Its weight W acts through the centre of gravity G. Forces also act on the ladder at P and Q. These forces are P and Q respectively. Which… Continue Reading

## Using Loom and GeoGebra to explain a tutorial question

It’s Day 1 of the full home-based learning month in Singapore! As teachers all over Singapore scramble to understand the use of the myriad EdTech tools, I have finally come to settle on a few: Google Meet to do video… Continue Reading

## Home-Based Learning Using Google Meet

I conducted an online lecture this morning using Google Meet for the students who had to stay home due to the Leave of Absence mandated by the Ministry since they had recently returned from another country during this period of… Continue Reading

## Prepopulated Free-Response Question in SLS

Now that the newest release of the Student Learning Space (SLS) is live, I was keen to try out the new features. Having heard that there is an option for prepopulated free response questions where students can draw on prefilled… Continue Reading

## Measuring Difference in Drop Time Using PhyPhox

In a recent class on Kinematics, I prepared a string of 4 pendulum balls, each separated about 20 cm apart and dropped them from a height. Before that, I got students to predict whether the intervals in time between drops… Continue Reading

## Embedding GeoGebra Apps into SLS

Teachers in Singapore have been provided with the Student Learning Space (SLS) – an online platform meant for students’ self-directed learning using MOE’s curriculum-aligned resources as well as for teachers to create engaging technology-assisted learning experiences for their charges. One of… Continue Reading
