As an instructional designer, I can see the benefits of microlearning platforms. These tools help reduce long, painful training experiences into engaging, multimodal snippets of learning. I could see using these to increase user participation in a course, or as a tool for blended learning. I don't think I would necessarily rely on some of them for deeper learning, as many of them focus on simple quizzes and other quick memorization tools. After digging into this topic, there are several platforms which I would love to work with- where I feel like there is room for creativity in the design, look and feel of the lessons delivered, as well as options to create lots of different styles of lessons. There are a lot of platforms out there, and all of them claim to be the best in the industry, so before investing in any of these companies, I would need to see that they are coming up with new ideas, are backed by a great team and show customer testimonies that prove good performance. If I had to narrow down my choice to one frontrunner, my current choice based on this criteria would be Arist, as it would be interesting to add text-based lessons to a course, and this is a different offering than many of the other platforms available.
