Primary Computing – A Teacher Guide for Mozilla Thimble

Mozilla Thimble

Create and share your own webpages with Mozilla Thimble

As part of my role as a primary computer science master teacher, I train teachers on how to teach the new primary computing curriculum.

When covering networks, the internet and the world wide web, I can’t wait to introduce teachers to the delights of Mozilla X-Ray Goggles (which everyone loves!) and basic web page creation using Mozilla Thimble: an online HTML editor.

I use these tools with Key Stage 2 children as part of iCompute‘s iWeb and iNetwork 6 week units for Years 5 and 6 respectively.  They are excellent for introducing children to how web content is constructed using HTML (Hyper Text Markup Language) and styled with CSS (Cascading Style Sheets).

Mozilla Thimble allows children to work together in remixing and creating their own web pages.  It provides a wonderful opportunity for children to become digital creators themselves; with huge cross-curricular potential as it offers an exciting new way for children to communicate, collaborate, create and express themselves online using digital technologies – one of the aims of the digital literacy aspects of the new primary computing curriculum.

Teachers have asked me to provide a guide as to how children can use the collaborate facility of Mozilla Thimble to work together on the same project – communicating and collaborating – thereby addressing one of the Key Stage 2 objectives of the new National Curriculum for Computing at KS1 and KS2.

It is provided as one of a number of teacher guides within iCompute’s primary computing scheme of work and I offer it here, along with a cheat-sheet resource, for everyone to use to help get their pupils started on an exciting path towards becoming the next generation of Super Star Web Masters!
