Important info - Relevant Implications - Accessibility
This week has been about improving our Google Learning Sites. Apart from content and structure, Teachers, as part of UDL (Universal Design for Learning), need to understand web accessibility standards, for example having info / text inside images / banners without readable text / ALT tags. It is a NZ legal requirement for public buildings and webs sites to be accessible (e.g. ramps / lifts for wheelchair users in schools), however, we are blocking low vision users if text cannot be read aloud be screen readers.
As a web designer, we stopped creating web buttons in Photoshop when we started using CSS 2.0. Apart from being less efficient, graphical text buttons hurt a website. This is due to the issue of SEO (search engine optimisation). Web spiders cannot crawl and parse text inside images.
Teachers could be ignorant of the needs of low vision users perhaps thinking that they know their class students, however, we are trying to have visible learning for whanau - and so we need to accommodate the needs of elderly or vision impaired.
This is an NCEA requirement for Digital Technologies Levels 1-3. I've made a learning site page with Relevant Implications posters: https://sites.google.com/westlandhigh.school.nz/technology/new-dtec/12-13-dthm/implications

Positives of Today
Lots of Good advice shared in the slideshow resources. Nice tip for teachers to use Google Drawing because I would have used Photoshop or Pixlr.com/e/ but using G. Drawing is more accessible for staff.
I was happy to share my site and resources because we all stand on the shoulders of others.
Today's Take Away
Personally thought it was a great tip to create Learning Site banners at W1000 x H 250 px. Learning Sites are responsive so the banner will sometimes crop when bigger. I tend to use them as a texture and then add text over the top. Setting them as 2000 x 500px produces a better non-pixelated result.
I also worked on improving the new topics. Since we are in lockdown I have had to change my plan from teaching Computational Thinking with Tello https://www.droneblocks.io to using Minecraft Edu on students Chromebooks.
