Wrong-headed attempt to practice “brain research” and all that. This looks like the same “research” that lead to some childrens’ shows changing to quick, jumpy sequences that do not let the child concentrate. Quite opposed to what Montessori teaches and does!! It appears that the class in the video is functioning on the premise that we learn best when we learn in a “multi-sensory” fashion. Not necessarily the case. That idea has to be put in context (like the ancient Greeks, we should engage in full analysis and synthesis of the idea); it should not be taken and run with like a wild animal running scared from the wind.
