摘要：Editorial note Alexander Fyodorovich Lazurskiy (1874–1917), known by his devotion to the experiment as a main method of scientific data obtaining, gave his talk on the 1st Congress for Experimental Pedagogics in December, 1910. His report was about "natural experiment". This term was proposed by the author to denote such methods that lay between external, objective observation and laboratory experiment.
