Maths for A Level Computer Science CP518
An introduction to databases for A-level teachers. Gain confidence in teaching the databases content in the A-level specification including attempting and marking exam questions.
Summary
Enhance your A-level CS teaching with a deep focus on number representation. This course covers binary/denary conversions, floating point numbers, normalisation, and related mathematical operations, boosting your confidence in teaching maths-related content.
We want to help support your journey into the A Level classroom and a key step for many teachers teaching A Level is getting to grips with floating point representation of numbers. We will show you the steps to then pass on to your students to give them the very best chances in their learning.
In this three-hour CPD session, you will strengthen your theoretical understanding and practical skills in number representation. You'll learn to perform conversions, handle floating point numbers, and normalise data. Through interactive discussions and hands-on activities, you will explore effective pedagogical approaches and become equipped to teach these concepts with confidence. Collaborate with peers and gain valuable insights to integrate these topics seamlessly into your curriculum.
Who is it for?
This course is aimed at teachers delivering A Level computer science. Since this content is not covered in most GCSE specifications we will take you right from the very basics to the more advanced topics.
