Think about your product. How long will it take to get the development done? Is it feasible in a reasonable timeframe?
The development took longer because I went over each step of the lesson and took a screenshot of it. But I think the screenshots is very helpful for learners who need to see it to learn. It was beneficial for me to, because I got better doing it one more time.
It won’t take too long for learners to go thru the lesson. The assessments will probably take a little longer. The first time I worked with Photoshop, I had a hard time, to change the color of an object, but I know that some high school students can learn stuff much faster than I can. But since it is posted online, they can also take a break and go back to it later. It is one of the advantages of e-learning.
