This is an OER course on instruction design that, appropriately, is a reasonably good example of instructional design. I say reasonably because it could be better in terms of visual design and wayfinding.
Designing and Teaching for Impact in Online Courses
This course could be a more visually effective, but on balance it's a decent example of ID principles like chunking content, checking for knowledge, and accessibility. BONUS: Lots of good ID info in the course itself.
As a website, this is a little annoying (you have to click on all the items before you can proceed). But there are some good ideas for learning design.
Why it's good: (1) The time and location text is large, making this an easy design to scan. (2) The white background clearly segments these blocks of text and helps lighten the right side of the design. (3) The different colors on the presenters help keep the text box from becoming a non-descript blob.
Why it's good: (1) The text colors alternate in a way that makes sense – you could just read the red text (or vice a versa) and get the gist of what this poster is about. (2) The most important information (when and where) is located at the top, in black text (easier to read than red), and with decent spacing and differentiation in text size.
Why it's good: (1) The semi-transparent overlays on the left help the text stand out. And since the overlays are colored to match the background, they don’t look too stark. (2) The colors in the design match the logo, which helps tie the two pieces together. (3) Artfully-done gradient adds some perspective to this flat design.
The X factor: The Secret to Better Content Marketing
These slides "break" some of the rules I generally recommend. For example, there's a lot of text on each slide, multiple (and fancy) font types, and patterned backgrounds. But it more or less works. Proof that there's an exception to every rule...
