Advanced Programming with LiveCode

This series of lessons and exercises covers more advanced programming concepts and techniques. Pseudocode is used within the full development cycle to aid understanding of event-driven programs. Variables are covered in-depth, and a range of loops and selection statements are used for flow of control. Complex array...

Data Representation: Bitmap Images

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

Sweet Learning Computer

To play a simple game called Hexapawn, an ‘artificially intelligent’ computer is created made entirely from sweets. The game is like a mini version of chess; the rules are explained fully, and a playing board drawn. The ‘machine’ then ‘learns’ how to improve its playing of the game by trial and error and by ‘...

Teleporting Robot

This CS4FN activity from the team at Queen Mary University of London highlights some issues encountered during the design of human-computer interfaces (HCI). It acts as an introduction to HCI, introducing the need to translate problems and to understand how people behave.

The activities include a robot...

Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...
