When I input the learning resources I want to design, which is the rational consumption of consumers, lots of the videos appeared, and I don’t even need to choose one of them because they are all very similar. They all use direct-instruction. These videos can be said to force students to remember the knowledge in the video. Although there are no tests and exams in the video. But if you are not familiar with the content contained in the video, then you may not understand the following advanced instructional video on this topic. As a student, I think most students will choose to take notes to help them remember the knowledge they need to master. Taking notes can help us remember knowledge very effectively, so it is highly effective for direct-instruction teaching methods. For the activities after watching the video, I think about the learning resources I want to design, go to the Internet to find exercises. They can use some learning web pages to do exercises, like learning web pages like quizlet. If you let me design an activity, I think it is very necessary to design the exam. Although it is very boring, it can help students understand related theories and calculations. And the feedback that students get is exactly accurate, that is their exam results. If it is normal, paper-based face-to-face exams are quite common. If you consider the current epidemic, then open-book exams on the Internet are also acceptable. After the exam, you can open a network-taught test paper that must be resolved, which is the final term Prepare for the exam. Setting up an exam is relatively simple but time-consuming for me. The exams on the Internet can be corrected directly by the computer, but face-to-face exams require me to correct them, and then there will be statistical scores, although it is not difficult but It is a waste of time.
