The Purbeck School Computing Curriculum 

The Purbeck School delivers the aims of the National Curriculum and Computing at School (CAS) computing curriculum, which is endorsed by both Microsoft, Google and BCS for KS3 and KS4: 


Rationale and Ambition for the Purbeck School Computing Curriculum: 

“Computer Science and Information Technology are complementary subjects.  Computer science teaches a pupil how to be an effective author of computational tools (i.e. software), while IT teaches how to be a thoughtful user of those tools.” 

Computer Science: A Curriculum for Schools 

  • The Purbeck School Computing curriculum is taught to KS3, to enable students to gain a better understanding of the subject content, should they choose opt to learn the subject at GCSE.   
  • The Purbeck School Computing curriculum at KS3 introduces computing concepts and disciplines at an earlier stage, thus making the transition from KS3 to KS4 easier for the students. 



The Purbeck School Computing Curriculum aims to teach disciplines with long term value, rather than with short-term usefulness, although being able to use computers, is obviously useful.  The disciplines we aim to teach:- 

  • A body of knowledge, including widely-applicable ideas and concepts, and a theoretical framework into which ideas and concepts fit. 
  • A set of techniques and methods that may be applied in the solution of problems, and in the advancement of knowledge. 
  • A way of thinking and working that provides a perspective of the world that is distinct from other disciplines. 
  • Longevity: a discipline does not “date” quickly, although the subject advances. 
  • Independence from specific technologies, especially those that have a short shelf life. 

The Computing Curriculum is centred on the development of the above concepts from year seven through to year eleven. Progression within these concepts can only be achieved through the development of secure knowledge and understanding; once students are fluent in knowledge, such as the knowledge of computational thinking or programming concepts, they can then apply this knowledge as skills. It is, therefore, through the development of knowledge that that students become more confident and demonstrate higher levels of understanding in the discipline of Computing. The core knowledge that supports progression in these concepts is planned in lessons and supported through knowledge organiser home learning tasks for KS3, and at KS4, students are taught through a ‘Flipped Learning’ approach, where they come to the lesson prepared, and are then able to explore the content further.
