Python programming constructs: sequencing, selection & iteration for AQA specification CB423B / E02

Start date
22 Jul 24
6 Hours
Learning Method
Remote Delivered CPD


Take your first steps to becoming a competent teacher of Python programming; this CPD will develop your foundational knowledge around the Python language. This course references the AQA 8525 9-1 GCSE Computer Science specification and the pseudocode representation that will be used in exams.

You’ll learn how to write code to input, process and output data, and how to manipulate data stored in variables. Using the building blocks of sequence, selection and iteration you’ll begin to understand how programs are constructed to perform a multitude of simple and more complex tasks.

You’ll gain confidence with lots of hands-on experience under the guidance of highly successful teachers of computer science.

Mapped closely to the specifications of GCSE computer science, the course will provide you with essential knowledge leading to expertise in teaching programming

References of exam boards:

This course has been developed to reference the AQA 8525 9-1 GCSE Computer Science specification, if you’re not teaching the AQA specification you may wish to consider booking the equivalent OCR or Pearson version of the course. Alternatively, you may wish to book the agnostic remote or face-to-face version of the course.

Who is it for?

You’ll benefit from having some experience of basic programming, perhaps using a block-based language, to access this GCSE-level subject

knowledge enhancement. You should have some understanding of the AQA 8525 GCSE 9-1 Computer Science specification.

If you are entirely new to computer science, we recommend first participating in our one-day course: An Introduction to algorithms, programming and data in computer science.  

What topics are covered?

•01 | Inputs, outputs & variables – explore how to utilise inputs and outputs in Python, including the use of variables and efficient use of simple data types.

•02 | Building a working program –create a working Python program using inputs, outputs and variables based upon a set of user requirements.

•03 | Selection – learn how to write branching programs using selection. Understand how to apply operators and use nested selection within a program.

•04 | Working with selection – create a working Python program using selection and other programming techniques learnt.

•05 | Iteration – this session will help you create code that repeats using count and condition controlled loops in Python.

How will you learn?

Scheduled live, interactive online sessions led by an experienced practitioner. Flexible Professional Development Leader-supported, participant-led sessions, involving deep exploration of the subject content. The course will model teaching approaches that can be taken back to the classroom.

How long is this course?

This course is approximately 5 hours in duration, split across several days.

Who is the course leader?


● Become familiar with the Python programming language

● Develop some basic program constructs using variables, handling user input and output to the screen

● Use mathematical and logical operators to build functionality into programs

● Follow the flow of a program, identifying values held in variables at different stages of execution

● Create and control indefinite loop structures in programs

● Begin to evaluate programs and suggest improvements
