Introduction to Computing/IT
IT lessons have moved away from traditional IT topics; such as creating spreadsheets, posters, presentations and websites, to computing based topics. Students learn about how computers work, how they can be connected to networks and computers communicate with each other. Students are required to learn about why the internet was created, how the internet works and how to write code to create a multiple page website. Students develop their understanding of computers from being basic users of computers to how they function and what is going on behind the scenes.
IT at KS4
At Key-Stage-Four students can opt to study GCSE Computer Science. The students complete the Edexcel GCSE, which consists of three units (two exams and one controlled assessment unit). Students develop the knowledge that they have developed at Key-Stage-Three to a much deeper level. For example, students go from knowing the purpose of a processor to understanding what a processor is made up from and how the individual components work. Students look at how computers communicate using binary code and are able to convert binary numbers into denary, hexadecimal, twos compliment, and addition. Computer Science is a very enjoyable and challenging subject as there are lots of new topics to learn throughout the course.
Unit One is a 1 hour 40-minute exam on ‘The Principles of Computer Science’. This is a multiple choice and short answer paper. In the exam students will be questioned on; Hardware/Software, Data Representation, HTML&CSS, Encryption, Compression, Relational Databases and Algorithms. The Computer Science qualification teaches students how computers, software and the internet work.
Unit Two is a second exam lasting 2-hours on the Application of Computational Thinking’. This is an open and extended answer question paper. In the exam students will be questioned on; Creating and Interpreting Algorithms, Data Types, Program Code and Operators.
Unit Three is a controlled assessment task that is worth 20% of the qualification. Students will learn about the Python programming language and how to write computer programs. The controlled assessment requires students to; diagnose a problem, create algorithms, write a program and test their solution.
