Questioning praise; where's the wise stance in regards kudos?

An excess of praise may be doing kids more harm than good, says the NY Times:

A cover story in this month’s Scholastic Instructor magazine asks whether kids today are “overpraised.'’ The concern is that by focusing on self-esteem and confidence building, parents and teachers may be giving real goals and achievement short shrift. The article cites a recent study in which eighth graders in Korea and the United States were asked whether they were good at math. Among the American students, 39 percent said they were excellent at math, compared to just 6 percent of the Korean eighth graders. But the reality was somewhat different. The Korean kids scored far better in math than the over-confident American students.

The notion that you can praise a kid too much is heresy to parents and teachers who have long believed that building self-esteem should be the cornerstone of education. If kids believe in themselves, the thinking goes, achievement will naturally follow. But confidence doesn’t always produce better students.
