The Scratch patch - bubble sort algorithm

This short practical guide shows how to implement a bubble sort algorithm in Scratch. The procedure is easy to follow, and can be used in conjunction with theory or unplugged activities to aid understanding.

The Scratch patch - the Julia set

This visual mathematics project focuses on the beautiful images known as Julia Sets (named after French mathematician Gaston Julia). Students use a repeated iterations to explore the world of complex numbers, writing and amending a relatively complicated Scratch program. 

The Scratch patch - king of the heap (sort)

Suitable for students throughout secondary computing, including those studying at an advanced level, this exercise introduces the Heap Sort and explores why it is more efficient than the Bubble Sort in another Scratch Patch article. Students learn about tree data structures, including the correct terminology for...

The Scratch patch - crash, bang, wallop! Create a simple racing car game

This simple game is an engaging way to extend learning in Scratch. It uses fairly simple scripts running in parallel to detect collisions and move sprites, which have been designed in the Scratch environment. It could be used a basis for other similar ‘scrolling’ games. 

The Scratch patch - physics of a cannon ball

Combining some fundamental physics with trigonometry and computer programming, this guide helps students to create a simulation of the projectile motion of a cannon ball. The concepts are all briefly explained, and the program introduces some clever mathematics as well as game elements, such as collision detection...

CS4FN issue 20

2015 is the 200th anniversary of Ada Lovelace’s birth. Famous as ‘the first programmer’ her vision of computer science was far wider. To celebrate, issue 20 of CS4FN magazine explores her life, her ideas and where modern research has taken some of those ideas. Women’s research is also still at the...

STEM Learning Magazine: Post-16 and FE - Spring 2016

Under the banner of Building a successful network, Dr Katherine Forsey and Sue Churm consider how to create a technical network and how to get the most from it, Jenny Phillips explores the challenges FE practitioners face and Ed Walsh explains what the teacher recognition scheme...
