If you’re looking for some good explanations of computing-related concepts, or simply interesting ideas to discuss in your classroom, you should fins something here.

This list is part of an article I wrote for Sec-Ed in 2018.

BBC Bitesize (GCSE Computer Science): Good for class tips – the videos are very short and accessible and it’s designed for use with students: http://bit.ly/SecEdBBC

Code.org: This has a nice series on how computers work, plus very short lessons aimed at students, such as “what is the internet?”: http://bit.ly/SecEdCode

Computerphile: The Computerphile videos are short and updated frequently. They are very geeky, with topics such as meta-programming, and the history of the byte. Good if you want to delve more deeply into the subject, even if some of the subjects won’t be directly relevant to your teaching: http://bit.ly/SecEdComp

Computing At School: CAS is a well-known brand. The videos are a little sporadic, and don’t appear to have a set frequency. The subjects covered are wide-ranging. The good thing is that the videos are aimed at teachers of the computing national curriculum: www.youtube.com/user/computingatschool

CraignDave: The CraignDave video channel features two teachers of computer science, and covers the OCR AS level, A level and GCSE specifications, although to some extent the subject matter is generic. The videos are very short at under 10 minutes, and are on very specific topics, like the Fetch-Decode-Execute cycle, or performance of the cpu. Useful for teachers, and also for introducing a topic in class: http://bit.ly/SecEdCraig

CS Unplugged: CS Unplugged’s existing range of videos are very useful for getting students to understand concepts:

MIT Open Courseware: Features lectures from around 40 to 60 minutes long. There are playlists on topics such as programming for the puzzled. The lectures are both interesting and accessible. They are probably useful for teachers who lack subject knowledge: http://bit.ly/SecEdMIT

MyCodeSchool: Unfortunately, this is no longer updated. However, the existing videos are very short and on very specific topics, such as binary search, sorting algorithms, and a series on data structures. They could be useful for students’ private study, as they include accessible examples: http://bit.ly/SecEdCodeSchool

Telusko Learnings: Telusko Learnings videos are short – under 10 minutes – and aimed at computing enthusiasts. Topics include: How to improve your programming skills, What is blockchain?, What is servlet?, and Working with JSP. The presenter speaks very fast so they are probably not useful for classroom teaching as a matter of course, although some topics may be of interest: http://bit.ly/SecEdTelusko

TheNewBoston: The New Boston channel comprises short tutorial videos (under 10 minutes) on topics such as how to create apps in Android, javascript programming, html and python. It’s American, so not directly aligned to the UK curriculums. Nevertheless, it may be useful as a go-to resource should students be having difficulties: http://bit.ly/SecEdBoston
