Let us make an assumption of students must study at home under the situation of pandemic. In addition to this, I would like to make the additional assumption that my students include a few with color blindness or loss of hearing. My group interactive learning resource is about the history of Chinese dynasties. Under such a situation of pandemic, I will do online teaching. I will provide weekly asynchronous lecture videos and some videos from the Internet that can be used as teaching material to students. The reason for asynchronous video is that students may not be able to keep their attention on the online course due to the lack of learning atmosphere or other factors, so the recorded videos is easy for students to study again and again after class and make up for the knowledge gaps. Of course, any video-based instruction must include synchronous captioning to help the students with loss of hearing learn. When it comes to the need for some pictures to deliver teaching content, I will choose some pictures where color does not play an important role. In other words, students with color blindness can learn and understand through pictures just like normal students. In addition to the videos, I will also provide some relevant articles for students to read and learn. Of course, assessments are also essential. Students will also have to pass quizzes and give presentations to reflect their knowledge, but these will all be online. Quizzes may be administered on a multiple choice and short answer basis. Office Hour will also be set up as usual. In addition, I will also set up an online forum for students to discuss and ask me questions. In fact, some students may not communicate with instructors or classmates in person because of shyness and other reasons, so online forums may be a good place for them to communicate and ask or answer questions.
