For instance, a number of routine skills regarding arithmetic, spelling, and grammar certainly need development. Among the many agendas of education, surely understanding must rank far up on the short list of high priorities. It would encourage them to give even more attention to understanding than they already do and help them with strategies for doing so. Good answers are not at all obvious. To draw a contrast, we all have a reasonable conception of what knowing is.
Understanding is a subtler matter, which goes beyond knowing.
To answer this question, we have formulated a view of understanding consonant with both common sense and a number of sources in contemporary cognitive science. But suppose the student could find examples in everyday experience. Suppose the student could make predictions that would illustrate the theory. The better the student could handle a variety of thought-demanding tasks concerning Newton's theory, the readier we would be to say that the student understood. By no means.
