The four layer TCP/IP model

This resource consists of a lesson plan from Cybersecurity Challenge UK on the topic of the TCP/IP model of networking. It would be useful as a topic introduction.

Compression and encryption theory

This resource consists of two documents. One is a theory sheet and the other a structured workbook for students to complete. This would form a useful independent learning resource so could be issued as a homework task.

Database Management Systems (DBMS) and distributed databases

Two topics that support the database topic are covered in this presentation. The emphasis at A level is investigating the technical architecture rather than application. These are two important topics often tricky to find resources for. 

Relational databases

It is often very helpful to reiterate vocabulary and definitions associated with database technology. This resource can be used as a starter or a plenary activity to reinforce key terminology.

Python and SQL

Databases are a fundamental part of modern organisations. This resource consists of an activity sheet, answer sheet and a highly usable utility for using SQLite with Python. The activities enable students to produce implement what they have learned from the theoretical content.

 

Algorithm efficiency

From a more mathematical perspective this time, this document covers the derivation of algorithm complexity. It could be used in the classroom as extension reading  or as a homework. 

Big O Notation

This presentation covers algorithms and their complexity expressed as Big O notation. This could be used by students as a revision aid or as a basic introduction to the topic.

Computational thinking: Puzzling tours

This is a very comprehensive resource covering a range of pathfinding algorithm activities using graphs. It includes the Knight’s Tour puzzle as well as other examples. This is a highly readable resource that could be used for smaller activities including homework.

Create a Face

This unplugged activity uses a large model of a face, operated by several children working together, to teach how ‘emotion’ can be expressed by robots following simple rules. These rules are expressed as IF, THEN, ELSE, statements which, when combined, show the complex movement of a whole face in reaction to...

Boolean algebra exploration

This set of resources provides comprehensive coverage of the topic of logic, Boolean algebra and simplifying expressions using Karnaugh maps. There are a series of student activities involving deriving expressions from logic gate combinations, rules of Boolean algebra and building logic expressions.
