In "The Three Rs and an S," a recent op-ed in The Baltimore Sun, you and Norman Augustine write that the Next Generation Science Standards will teach students how to take on a scientific manner of thinking. Why is there a greater emphasis now on this approach to learning than in years past? The future jobs for this millennial generation will not look like the jobs of the last 40 or 50 years. They're not going to be large segments of people working in factories. Really, what's happened is that the business community itself has sort of shifted where it sees efficiency and productivity occurring and, because of this shift, the jobs are going to shift.
