Mention at least two major contributors

Two major contributors to the field of Comparative Education are:

1. Marc-Antoine Jullien de Paris: Often considered the "father of comparative education," he proposed in 1817 a systematic approach to studying foreign education systems, advocating for the collection of detailed information on curricula, teaching methods, and school organization to inform national educational reforms.

2. Michael Sadler: A British educationist, Sadler argued in the early 20th century that education systems could not be understood in isolation. He emphasized the importance of studying the social, cultural, and historical contexts of a nation when comparing its educational practices, shifting the focus from simply "borrowing" ideas to deeper analysis.
