National Salvation

From Science Popularization to Shanhai Work-Study Union

（1931——1936）

In 1931，Tao returned in secret from Japan to Shanghai and devoted himself to the composition of his treatises，seeking new approaches for Chinese education at the time of national crisis. He developed his ideology of life education and constructed a broader view of the theory of “life education”.

 China was plunged into national crisis after the outbreaks of the “September Eighteenth Incident” and the “January Twenty-Eighteenth Incident”. In order to relieve China and its people from the crisis, Tao carried out the most large-scaled and multi-leveled Science Popularization Movement in the history of modern Chinese education, launching the Work-Study-Union Movement that integrated workshops, schools and society, the Mass Education Movement in which “little teachers” were learners as well as teachers, and the National Crisis Education Movement and Wartime Education Movement which meant to resist the invasion of Japanese. The Movement of Life Education was promoted to a new phase.
