Describe progressive education and its impact on the kindergarten movement

Historians have debated whether a unified progressive reform movement existed during the decades surrounding the turn of the twentieth century. While some scholars have doubted the development of a cohesive progressive project, others have argued that while Progressive Era reformers did not march in lockstep, they did draw from a common reform discourse that connected their separate agendas in spirit, if not in kind. Despite these scholarly debates, historians of education have reached a consensus on the central importance of the Progressive Era and the educational reformers who shaped it during the early twentieth century. This is not to say that historians of education do not disagree-in fact, they disagree intensely-on the legacy of Progressive educational experiments. What they do agree on is that during the Progressive Era (1890-1919) the philosophical, pedagogical, and administrative underpinnings of what is, in the early twenty-first century, associated with modern schooling, coalesced and transformed, for better or worse, the trajectory of twentieth-century American education.
