4) OPINION: Do we need more or less emphasis of either Core Knowledge or 21st Century Learning Skills? How would we go about it?

I think for my position and working with student with special needs, we need more core knowledge. In that I would like to supply all of my students with the basic knowledge they need in order to succeed and move higher up on the educational skills. That requires getting rid of grade and core curriculum for students who are in 4^th grade but are operating at a kinder level. How am I able to teach core curriculum to students who do not have the core knowledge to begin with?
