Pros
I have never had the pleasure of being in the presence of so many people dedicated to the delivery of well-researched, creative science curriculum. The developers leave nothing to chance, and work diligently to create a comprehensive, effective science curriculum
Cons
Delta Education was acquired by School Specialty, a struggling company. With the advent of technology, web-based instruction, and personal communication devices, their core business of agenda books and planners disappeared. They took a profitable, forward-thinking organization and dismantled it.
