I liked how you used the spatial contiguity principle in your blog, attaching an image of lesson planning directly after discussing this topic. This was a great way of helping the audience learn from words and images presented close to one another.
I thought the point from description of principles that directly relate to videos with popup text and embedded questions was a refreshing way of delivering clear information. This use of the coherence principle eliminated all extraneous information so people could easily identify the key points.
I wonder if, along with your excellent, straight-forward points on the principles, an example incorporating each of the principles discussed could be used? I believe this use of the worked examples principle could help the audience personally apply each principle.
Overall, this was an engaging, coherent post which helped me strengthen my knowledge of the concepts.
