I teach both IGCSE and A/AS Levels CS, and these slides are incredibly helpful in my teaching. Honestly, it's quite challenging to find high-quality teaching materials for computer science. Not only is this product very informative, but it also has a visually appealing design that captures my students' attention in class. Each chapter of the course goes along with past paper questions and mark schemes. Thanks to these slides, I can save a lot of time on lesson planning and assessment preparation.

    I’ve used these PowerPoint presentations for IGCSE 0478 and A-Level 9618 for two years without fault. They’re clear, detailed, and align perfectly with the syllabus. My teaching feels more professional, and students love them. I trust them 100%—a fantastic resource for any Computer Science teacher.

    As a Computer Science teacher with years of experience teaching both IGCSE and A-Level curricula, I am delighted to share how James Gan’s slides have become an invaluable asset in my daily teaching practice. These materials have not only streamlined my lesson preparation but also significantly enhanced student engagement and understanding across key stages of their learning journey.

  • Daniel Spear

    These resources are great and good to use as a start or even to help cover the whole course. They are nice and clear and also simple to follow along with.

  • The Computer Science package has helped me tremendously - saving me time and inspiring how I teach sections. My classes aren't really geared towards powerpoints per se, but I sometimes do use the chapter powerpoints as is in class - it's just a great way of explaining. Other times, I use the powerpoints as inspiration and direction in terms of how to teach a specific area. Very grateful to have found this resource and can highly recommend it.

    Jeanne-Marie Loveday - Newberry School

  • This is a very thoughtfully created resource. It closely follows the syllabus specifications and is organised in an exceptionally clear and easy-to-navigate manner. The explanations are concise yet detailed, making complex concepts accessible for students. Overall, it’s evident that a lot of care and expertise has gone into putting this together.

     FAQs

    • Absolutely! You'll receive two versions of the slides: editable and non-editable. This flexibility allows you to tailor the design to perfectly align with your unique teaching style and preferences.

    • The reason I decide to make 2 different editions is because some of the beautiful font and image cannot be preserved once it is converted from Canva to PowerPoint. To ensure you are receiving highest quality slides, I downloaded all my design as .png file and put them into the slides. This is why some of the beautiful slides are not editable as they are all in .png format. However, if you wish to add your own elements into the slide, you can still use the editable version.

    • Certainly! Explore our YouTube channel for comprehensive tutorials showcasing how to leverage our slides to explain various concepts effectively. These videos serve as valuable resources to guide you through the process and maximize the impact of our materials in your classroom.
