Using a mobile device, there is no way to adjust the pane sizes so more of the actual lesson can be viewed, and less of the menu options. Not very user friendly when, on a mobile device, one has to continuously toggle between sections or when directed to a another link (to verify credentials, register, or sign up for something). It would be helpful if both the credentials used for PSEA and/or NEA would transfer to the app automatically, or only ask for verification once and not multiple times. There are interactive parts during the lesson, one in particular will ask to sort cards. On a mobile device, the cards don’t “drop” into the area when released, they pop back to the starting point. Or, you have to figure out a way to immobilize the screen and double tap to “drop” the card in the area. It took too much time to try to figure out how to make this work, and even caused me to get an answer incorrect, which I was not happy about. Also, you cannot zoom in to read smaller printed texts, or turn the orientation of the phone to see more screen. There are some things to work out. After the course is completed, I will update with more information.
