Please read Miseducation: Preschoolers At Risk by David Elkind. Early childhood education should be a combination of what we know preschoolers should be exposed to at a developmentally appropriate level. Science, math, language arts, social studies should all be part of the early childhood curriculum, however in a way that is developmentally appropriate. The curriculum should be well designed and child centered. Art (not craft) should be a focus as preschoolers display their understanding of the world through art work - 2 dimensional and 3-dimensional. The program should be play orientated and adults should extend children's understandings through play. In the USA we focus too much on preparation for kindergarten which is now termed the new 1st grade. This is a huge mistake as more and more children are moving through the school system lacking in basic skills - socially, emotionally and academically. The early childhood years, 0-8 years, are the foundation of education in the later years. My heart breaks when I see so much developmentally inappropriate practice occurring in preschool through 2nd grade. As an intermediate teacher with solid early childhood training (outside of the US) I see the fallout for not paying enough attention to developmentally appropriate practice in all levels of education. Research Reggio Emilio in Italy, canvass and pressure our politicians to eliminate No Child Left Behind, which leaves most children behind. If the US education system does not wake up to what is going on, we will be left behind as a nation in the worldwide economy.
