I want to know the answer to the following question:
Whos educatgion approach was introduced in Germany in the 19th century and is used in most Kindergartens?
All the background I'm provided with is that "In time, some ideas from these experiments and paradigm challenges may be adopted as the norm in education, just as Friedrich Fröbel's approach to early childhood education in 19th-century Germany has been incorporated into contemporary kindergarten classrooms.". Is that enough to answer the question?
Answer: yes
