It differs from individual-rotation model. Lab-rotation model: The student rotates to a brick and mortar computer lab for online learning station. Flipped-classroom model: In this, the students rotate on a fixed schedule or at a teacher's discretion across the classroom learning and online learning after the school hours.
Rotating wheel space station. Wernher von Braun 1952 concept. A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Konstantin Tsiolkovsky in 1903, [1] the idea was expanded by Herman Potočnik in 1929, [2] and popularized by Wernher von Braun in 1952. [3]
The middle and high-étage types are depicted above the sky cover circle of the station model, while the main low-étage cloud type is indicated below the circle. [5] Since the station model has limited room, it makes no special provision for vertical or multi-level clouds that can occupy more than one étage at a particular time. [13]
In that model, however, issues arise in the size of the spacecraft. As expressed by John Page and Matthew Francis, the smaller a spacecraft (the shorter the radius of rotation), the more rapid the rotation that is required. As such, to simulate gravity, it would be better to utilize a larger spacecraft that rotates slowly.
The experiment has also been carried out at the South Pole, where it was assumed that the rotation of the Earth would have maximum effect. [34] [35] A pendulum was installed in a six-story staircase of a new station under construction at the Amundsen-Scott South Pole Station. It had a length of 33 m (108 ft) and the bob weighed 25 kg (55 lb).
A Bishop Ring [1] is a type of hypothetical rotating wheel space station originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering. [2] The concept is a smaller scale version of the Banks Orbital , which itself is a smaller version of the Niven ring . [ 3 ]

Older CMG models like the ones launched with Skylab in 1973 had limited gimbal travel between fixed mechanical stops. On the Skylab CMGs the limits were plus or minus 80 degrees from zero for the inner gimbals, and from plus 220 degrees to minus 130 degrees for the outer ones (so zero was offset by 45 degrees from the centre of travel).
