Play itWhat does this lesson cover?
Students often think a page that looks right on their screen works for everyone. This lesson teaches them to test for display, functionality and web accessibility, and to catch problems like broken links and missing alt text. It also teaches students to give specific, kind feedback and to decide which suggestions to use on their own page.
The lab on Day 2 has an online version that uses Web Lab, our online game, in the Launch Check level. It practices testing pages before they're published and fixing what the checks find. Every online version comes with a paper version, so no internet is needed. Our game is free, with no accounts or sign-ins.
Launch Check
Students test four pages and write what failed, the kind of test and the fix, on paper or in the Web Lab.
