The interactive learning resources this time are simple but comprehensive, and fully meet the part of normal economics that needs to be learned. After learning, it will not affect the subsequent learning of economics. If there is a pandemic, then this interactive learning resource can be transferred to the Internet for learning. The courseware can be uploaded to the learning website, and the teaching videos can be recorded in advance. Students may have problems with jet lag, and we can solve them by recording videos. For example, an activity I designed is to give students the same amount of money to allow students to buy different things. This activity allows students to intuitively feel that consumer preferences can affect consumer choices. Then I can change this activity to a questionnaire on the Internet to list the products that students can choose, but only give limited choices. Later feedback can be conducted in the form of online group discussions, and students can share their choices.
