Java programming with Greenfoot: class methods versus instance methods

This video tutorial explains clearly the differences and uses of internal method calls (a method called from the same class or inherited from the superclass), external method calls (when a method is called from an external source, such as a different class, mouse or keys) and static or instance methods (where...

Java programming with Greenfoot: image manipulation 2

In this video tutorial students are shown how to change an image by either drawing their own or inputting an image file.  They are then guided through using random numbers to change the colour, transparency, direction of movement and speed of the bouncing balls in their game using constructors.

Java programming with Greenfoot: refactoring for good style

This video explains good coding behaviour.  This includes an emphasis on refactoring (changing code to make its structure better so that it can later be easily changed or understood) and cohesion (ensuring that each method does only one thing).  It also explains that private methods will only apply to objects in...

Java programming with Greenfoot: smoke and mirrors (visual effects)

In this video tutorial students are shown how to add a visual effect to the animation in their bouncing ball game.  Balls will appear to leave a diminishing smoke trail behind them as they move.  This is achieved by leaving an object in the path the ball has followed that shrinks over time.  This is a simple but...

My Stem Ambassdor Spotlight

Data-logging with BBC micro:bits and MakeCode for modelling with Excel and GeoGebra.

Recent developments in MakeCode now make data-capture from micro:bits very simple via the USB cable.  The data can be graphed in real time in MakeCode and exproted as CSV files.  Using tools such as Excel and GeoGebra's Spreadsheet View, the data can be manipulated, analysed and modelled.  With a pair of...

People like me guidance

The two-and-a-half-hour People Like Me training for STEM Ambassadors covers the...
