I am a school teacher , and my feedback is based on school background upto sr. secondary course. The introduction, learning objective, key terms explanation at the beginning, reflection , asking questions, giving assignments, encouraging students to watch reference materials, school specific activities, board based activities, ( eg CBSE) like joyful learning, activities in the text book, practicals result and discussion or interpretation , art integration, learning by doing, extended learning,Formative assignments like some part of course in which teacher to students interaction and familiarity are required should be recorded by the instructor,
The main body of course in the various forms are available in website as like videos , ppt, animations etc should be curated by the instructor.Because majority of teachers are not professional video recorders and editors. Not have much infrastructural facilities like camera,lighting computer with high ram, editing softwares etc. professionally made videos and such materials can be combined by a teacher depend on the course flow. example lecture by a good presenter and and activities / practicals recorded in good laboratories,real life videos etc. can be curated. as these are difficult for teachers to make.Gliches can make a best best teacher in face to face class as reputed worst teacher among parents and in online world.
Where ever a familiarity with instructor and learner is required, their only recording demands.
