I think using math programs over the summer is a good idea and could be really helpful. The programs using USA today articles could also be helpful but not as a replacement for reading books.
Again, I think technology has a place in schools but there needs to be a balance and more thoughtful approach guided by common sense and research. Lots of programs, including Utah's new on line preschool, seem to be designed to achieve limited academic goals.
Another recent article from NYT talked about txting behavior in girls and how compulsive texting appears to linked to lower grades. Preliminary research, but the researcher suggested having tech free zones and times, which seems reasonable to ensure kids learn to communicate in many different ways. I know current DCI parents have cited similar concerns.
