Python programming constructs: sequencing, selection & iteration CA423 / F01

Start date
29 Apr 20
5 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. 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.


Who is it for?

This course is for current or prospective teachers of GCSE computer science with some understanding of computer science fundamentals.


Prior knowledge

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

If you are entirely new to computer science, we recommend first participating in our one-day course an introduction to .


What does it cost?

This course is fully funded for participants from maintained schools in England. If you are from an independent school or from an organisation outside England, then the course fee is £220.


Course units

  • 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 facilitator-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 the course?

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




Learning outcomes

  • 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
