Reflection : This activity of making a digital book was the most fun of all the activities so far. It didn't have much technical difficulty in producing, and it didn't take long to produce. The best part was that I was able to express what I wanted to convey without any burden. In other words, creating such a digital book could be a universal educational tool that even beginners like me can easily use. I would like to use this class material in my class to help students access the subject of the lecture more easily and familiarly. Therefore, the main character of this activity was a cat, and the contents were organized so that children could think of creative solutions. Also, I think this activity could be an indicator of an extended class that can continue to present the opinions of individuals or teams using English.
