Final answer:
The outcomes of expanding public education in the early 20th century included the establishment of public high schools, rise in literacy rates, and founding of kindergartens. Growth in integrated schools occurred much later due to segregationist practices. These educational expansions were critical in creating a more educated society.
Step-by-step explanation:
The outcomes of expanding public education in the early 20th century include the establishment of public high schools, a significant rise in the literacy rate, and the founding of kindergartens. The growth of integrated schools, while an ideal, was slower to occur due to the segregationist policies of the time, which were not widely challenged until the mid-20th century.
The establishment of public high schools resulted from a recognition of the need for more advanced education to prepare students for a rapidly industrializing society. Public high school enrollment grew from one hundred schools nationally in 1860 to over six thousand by 1900. In conjunction with the development of high schools, early childhood education also expanded through the founding of kindergartens, which became more common in public school systems.
The expansion of public education had a hugely positive impact on literacy rates. By making basic education widely accessible, the percentage of literate individuals in society surged, thereby promoting a better-educated citizenry. Education reforms in the 19th and early 20th centuries were critical in shaping the modern educational landscape.
