Template for self-assessment questions

Here is a template that I might use to generate questions for students’ self-assessment in future. Based on a query that one of the participants in a GeoGebra online tutorial asked about generating random questions for simple multiplication for lower… Continue Reading

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
