  2. Using video distribution systems or Video conferencing systems Di ff

    i culty Detailed instruction, communication, physical learning Flexibility Easy to attend (distance, time) Easy to share information
 Di ffi cult to simply apply the previous methods used…? “I miss being able to discuss with other students.” “It would have been helpful to have chats and shared sheets.” “I liked having 
 the materials and reference information readily available.” Student Impressions in University Classes (partially modi fi ed) 2 Education under COVID-19 pandemic
  3. Use of video conferencing system (Zoom, etc.) In the beginning,

    the previous class method was simply applied. Example fo lesson fl ow Show the reference choreography Repeat Provide detailed guidance on how to move the part of choreography Practice Dance the whole part of choreography Dance education/lessons under COVID-19 pandemic Di ffi culty Di ff i cult to understand the complexity of instruction and choreography Di ff i cult to teach and communicate at the same time
  4. Di ff i cult to teach basic movements Network delay

    Timing of teacher's movements/sounds and students' movements/sounds are out of sync
 Di ffi cult to communicate each other Di ffi cult to give instructions to the whole group Di ffi cult to follow up with individual students Timing of movement and sound are out of sync. Di ffi cult to ask the instructor about 
 the parts that are hard to understand 4 Problem in Online Lesson
  5. Conventional: focus on real-time lesson Demerit Di ffi cult to

    understand the complexity of instruction and choreography Di ffi cult to teach and communicate at the same time Merit Easy to access (from anywhere) Easy to review interactions through recording videos Easy to see the interaction between the instructor and other students Instructor Student Zoom etc. Proposed: On-demand AI Dance Scoring Allows each student to learn in detail at their own pace Applying Flipped Classroom Scoring/Video feedback Instructor Student Zoom etc. Real-time Sharing craft language and perspectives 5 Dance lessons suitable for online environment
  6. A teaching style that replaces traditional classroom teaching (learning) 


    with homework (development and practice).ʢLage, Platt & Treglia, 2000ʣ Class ʢBasic learningʣ Homework ʢDevelopment) Class ʢDevelopmentʣ Homework ʢBasic learningʣ Traditional Classroom Flipped Classroom 6 Flipped classroom
  7. Problem in Online Lesson Di ff i cult to teach

    basic movements Network delay Timing of teacher's movements/sounds and students' movements/sounds are out of sync Di ffi cult to communicate each other Di ffi cult to give instructions to the whole group Di ffi cult to follow up with individual students 7 How can fl ipped classroom work? Solution Flipped Classroom Taking the basic movement practice o ff l ine Avoid timing deviations Allow students to make detailed corrections by themselves by repeatedly watching the video. (although communication is not possible).

  23. 23 Comments Instructor The students have been re fi ning

    the basic steps, 
 so I was able to implement real time smoothly. 
 Usually I have to teach from scratch, but I was able to focus on the application part. It feels like you are actually with the instructor. 
 And I can repeat the course as many times as I want. The advantage is that the student's anxiety is gone, 
 they are a little more familiar with the instructor, 
 and they can communicate with an open mind. Student The immersion is a lot of fun. 
 It's unusual, so that alone makes me want to do it. I felt like I was in a room by myself and could work on it comfortably and happily.
 I had no experience and thought I would never be able to participate in an environment where so many people were dancing around me, 
 but I was able to participate without feeling that way. In the real-time lessons, they picked up on my weak points right away with comments and such. 
 It was nice that they were fl exible and quick to respond to that, 
 like "let's take it slow.
