Suitable for students of computing and digital media in secondary school, this in-depth reference resource covers many aspects of image data storage and compression.

A brief introduction includes how images are perceived by the human eye and how they are captured and stored by digital devices. Also:

These resources, written in 2011 and provided by the Joint Mathematical Council (JMC), discuss the role that digital technologies might and should have in mathematics education. Consideration is given to the types of experiences students encounter and how best to develop the curriculum to engage students in using...

This set of three mini-interactive online games from Siemens explore a variety of digital industries:

• Cybersecurity
• Internet of Things
• Digital Twins

This resource from Jonny Griffiths contains a range of puzzles designed for 14 to 17 year old maths students. In each puzzle, the digits one to six have been rubbed out and replaced with six squares labelled a to f. The task is to put the digits back in again correctly to make each statement true...

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

This resource contains eight instant maths ideas designed to provide the opportunity for students to explore conversion graphs, compare imperial and metric units, estimate everyday measurements and explore the nature of different dimensions. The student resource sheet requires students to convert between different...

Mendeleev's invention of the periodic table of the elements showed how to predict and create further elements, something which scientists are still doing today.
