A question on this site deals with health aspects related to the posture while delivering a lecture.
My question is about the statistics regarding the same practice and its effect on students.
In general, the success of a lecture may depends on several factors like lecture notes, interactivity etc. Is standing/sitting (of an instructor) in classroom one among them? Does it effect teaching success in any way? Are there any stats related to it?
I know about some institutes having an explicit rule that an instructor should not sit while delivering a lecture and they provide neither chairs nor tables. Is this rule implemented in the institutes of many countries?
Note that sitting or standing by an instructor in this question refers to the instructor who either sits or stands throughout the lecture or at least 90% of the lecture.
