Getting your head around while loop - ITERATION for beginners.

(0)
Understanding variables and loops are the most significant aspects of coding. It is important for students in early stages to grasp the concept of how loops work if the are to be successful candidates for computer science. This power point presentation is a scaffold building fundamental steps required in understanding and applying loops using python. Students must already know how to use basic input and output functions in python. The language and terminology used is simple enough for a non specialist to use and teach a coder at beginner level. The python idle software is available to download for free at https://www.python.org/downloads/. After students have fully grasp the concept of loops and how they work, they extension task will provide a challenge for them to apply their knowledge, using computational thinking to improve their code.

A sound understanding of computing concepts will help students to see how to get the best from systems they use and how to solve problems when things go wrong. This series of lessons will empower students with fundamental computer coding skills to become potential creators of technology, and not limited to users. In addition, they will prepare potential computer science students who would like to study the subject at GCSE level with secure knowledge and computational thinking ability in key stage 2 and 3. This is the introductory lesson, structured in a flexible format to accommodate students with different abilities. It is advisable for students to be taught algorithms in scratch series before moving on to python. There adequate opportunity for students to practise and apply their skills whilst demonstrating/ documenting knowledge and understanding in attached evidence sheets. The lesson structure is simple to follow or teach even if you are not an experienced computer science teacher. This lesson covers the languages, algorithms and computation aspect from the national curriculum for computer science in England and Wales. Students will design, debug, test and discuss and document their own programs.

The significance of Testing (Computer Science GCSE A453 Project)

(0)
Testing is one of the most important processes when working on the computer science GCSE A453 project. Without testing a new system (project) thoroughly students may loose vital marks. This Power Point demonstrates how complex and difficult it is to test every possible outcome and teaches students to understand even the most rigorous of testing may not catch every error in the program. There are example case studies of situations where new computer systems or software upgrades have caused major problems because they have not been tested properly. Students/Testers are encouraged actively try to break the system, pushing it to extremes to test its strength and resilience. Students will also learn to write and demonstrate use of test plan.
