Twine story uses The Signaling Principle and The Segmenting Principle.
The Signaling Principle: In each segment, you can use bold font and underline to highlight the key points. Learners can quickly know the key points of learning and deepen their memory. This is also used to signal the end of the section and the beginning of the new section when switching topics.
The Segmenting Principle: The entire story is told one by one with a few connecting words, instead of a large text that can be very boring to students. It is much better when information is presented in segments rather than in succession. Students have the freedom to control the pace of learning, which is beneficial to their learning efficiency.
Twine story is a very interesting multimedia tool. I think it would be more convenient than PPT if it is used as a learning tool. For example, in a history class, you can use chronological order to explain the development of history to the students. Twine story is the most important point for me is that each new segment can be related to the previous one. It is easy to see the step by step process and the sequence of development. It is not confusing for the students to watch.
