Computer Science at Deira International School

Computer Science is a rapidly evolving discipline that combines a multitude of skills, including programming, problem-solving, mathematics, linguists and engineering. The DIS Computing and ICT curriculum provides students with a complete set of skills to become creative problem solvers. Computing has deep links with mathematics, science, and design and technology, and provides insights into both natural and artificial systems. The core of computing is computer science, in which students are taught the principles of information and computation, how digital systems work, and how to put this knowledge to use through programming. These competencies enable students to respond to familiar and unfamiliar situations by using computational and algorithmic thinking strategies to make educated decisions and resolve problems efficiently. Building on this knowledge and understanding; the spiral curriculum at DIS equips students to use information technology to create programs, systems and a range of content. The Computing curriculum also ensures that students become digitally literate – able to use, and express themselves and develop their ideas through, information and communication technology at a level suitable for the future workplace and as active participants in a digital world. The curriculum aim is to create an environment where there is a desire to learn new skills, develop creativity, foster independence and appreciate reflection. Within this framework, underpinning the KS3 curriculum are key enquiry-based questions which are focused around preparing students for IGCSE and IB course further up in the school. We aim to inspire and excite all students within a demanding academic environment.

Curriculum Intention  

1. Students will understand a range of ways to use technology safely, respectfully, responsibly, and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct and know how to report concerns.

2. Students will understand the hardware and software components that make up computer systems, and how they communicate with one another and with other systems.

3. Students will understand how instructions are stored and executed within a computer system.

Curriculum Implementation  

A mix of enquiry based, and guided learning projects are used to deliver both computing & ICT topics. This enables students to become familiar with the concept of combining software tools to solve problems as well as understand the theory to unpin the understanding of the technologies in preparation for KS4 and KS5.    

The variety of software used is constantly changing as our philosophy in the department is to encourage exploration and creativity. Whilst students are introduced to the common functions within mainstream software the focus is on developing their independent problem solving skills. We take care to ensure that through the KS3 ICT curriculum students not only learn important ICT skills which will help them with future studies but to also open their eyes to the wider world of ICT and computing such as creating animations, basic programming, flow diagrams & computer control and designing & writing web-pages in HTML. We also ensure that our students have a thorough understanding of how to stay safe online by introducing the topic at the start of every year with more advancing issues as they develop as young people.    

As a department, we encourage students to become independent in their learning by showing them how to use software but giving them the confidence to explore further both individually and through collaboration.  Providing students with core computer science skills helps prepare them for the technical challenges of the future, but also teaches them a wide range of transferable skills such as problem solving, logical reasoning and computational thinking.   

These skills provide a great base for students’ future careers where digital jobs and activity are becoming ever more important in traditionally non-digital areas of the economy, from retail to financial services and the public sector. It is estimated that the digital tech economy currently provides 1.56m jobs in the UK and moreover, that job growth in the digital tech economy is 2.8 times faster than the rest of the economy with the three biggest areas being in app development, data management and analytics and hardware, devices and open-source hardware.   

Assessment  

Students are assessed using a range of summative and formative assessments across all units. ONENOTE and student E Portfolio form a basis for assessment. These along with end of unit assessments, combined with class based work are used to determine current work at grades.
