Let's see if we can generate a consensus definition of "progressive education."

Progressive education is an approach to the educational process that acknowledges developmental and cognitive factors in the learner and which encourages the design of learning experiences designed to maximize engagement. Progressive education is built around the idea that students learn best when they are intellectually challenged, socially engaged, physically involved, and creatively stimulated. Embedded within the definition of progressive education is the idea that all students are capable of learning and that social and cultural factors in the learning environment must also be acknowledged as part of the learning experience. In addition to promoting individual learning and development academically, aesthetically, socially and physically, progressive education is explicitly intended to further social progress in a democratic society.
