A network learning system includes a host being coupled to a first user end and a second user end. A processor of the host end is configured to perform the following steps of: storing original lesson information being sent from the first user end in which the original lesson information has a plurality of content sections; selecting the content sections to form adaptive lesson information based on a learning condition of the second user end; sending the adaptive lesson information to the second user end so that an output device of the second user end outputs the adaptive lesson information based on a view of a simulated space; when the output device of the second user end outputs the adaptive lesson information, recording a value from an input device of the second user end.
