This video is on direct instruction, in which vivid pictures and video effects are added to help students understand knowledge. This video requires students to understand and write down most of the basic knowledge. The student council may watch the video repeatedly and take notes. There are no very interactive activities in the video, although for the subject of our learning resources, designing an interesting activity is not a very effective way to learn knowledge. And we did not add appropriate activities to increase the fun in the final learning resources. But I still want to mention the activities I designed before. In the chapter on rational consumption of consumers, students need to learn those factors that affect consumers’ choices. So I designed an activity to give students the same amount of money, Students go to buy different things. This activity allows students to intuitively feel that consumer preferences can affect consumer choices. If face-to-face courses are not possible, then this activity can be conducted in the form of a questionnaire, listing the products that students can choose but only giving limited choices. Subsequent feedback can be conducted in the form of online group discussions. Students can share their choices, which can just help students understand theoretical knowledge. In order for this activity to be effective, I need to design at least a questionnaire, and perhaps learn how to design a questionnaire on the Internet. I think it is worth spending this time if only learning the content of the unit of rational consumption by consumers. If you need to learn more about economics, then this activity is not worth it, because it is a waste of time and the content of this part is not that difficult.
