Dual Coding Theory
What makes students easily understand and remember knowledge? Graph, picture, and voice. There are dual coding theory methods when we use visual and verbal information to deepen understanding and associate things. For example, students prepare their presentations. They may make PowerPoint with graphic analysis to help their classmates to remember and understand topics.

Concept of Flow
There are several important points to pay attention to when students learn new things. The first is the student’s attention, the second is the degree of participation in the course, and the last is the student’s degree of understanding of knowledge. Multimedia learning can often attract students’ attention more, and instructors can also set up various discussions through the Internet so that students have a deeper understanding of the knowledge they learn every week.
The concept of learning flow allows us to understand the impact of concentration on learning. More engaged learning can often maintain a sense of excitement and explore learning content and knowledge.
Hypothesis
Hypothesis is a tool that gives students a platform to communicate and discuss. Especially, many students may be confused about the same problems. Students can highlight the same parts of the content in the file.
Potential benefits: Higher degree of participation. Students may not need to email instructors or TA.
Potential drawbacks: Waste time, cannot get answer directly.
However, the disadvantage of online learning is unavoidable. How to ensure that students are willing to participate in activities? To solve this problem, students can only rely on the students themselves.
