Thirty-one year old, Bobby Cramer, won his big league debut by pitching the Oakland Athletics over the Kansas City Royals 3-1. The ESPN SportsCenter hosts jumped all over this story because Cramer is a former math teacher. They showed math equations of two of his pitches using distance and time to calculate the speed of the pitch, which was an effective real-world math application.

Sadly, the anchors managed to pluck defeat from the jaws of victory. They simply could not leave well enough alone. Even though well-intentioned, they managed to completely undo the good they were doing for math teachers around the country.

In between their calculations the SportsCenter anchors made comments like “I was in remedial math” implying that theses simple equations were above their ability. One implied that it was a good thing that he had good writing skills, because high-level math like that would have kept him from graduating from college.

Several years ago, I was appearing on a PBS program with then Assistant Secretary of Education, Henry L. Johnson. The program was focused on how to encourage more students to take more math and science courses. At the wrap-up, the moderator asked me if I could make one recommendation to parents what would it be? I looked at the camera and said, “Never tell your child that you were good or bad at math and science! Anyone can be good at math and science if they are willing to work hard enough. Parents ruin their child’s math and science self-esteem by too often telling them that they were bad at math.”

According to Carol Dweck’s must read book for school leaders and parents, Mindset, what I had learned from years of practice, as a school leader, was spot on. Telling students that they are good or bad at a particular subject or skill is the wrong message because it ruins motivation. The message that our students need to hear is that work and effort create ability. “Your success or failure is the result of work, effort and deliberate practice.”

The message that the SportsCenter folks should have conveyed was that ‘Bobby Cramer’s years of hard work and practice paid off. He made it to the show, and in his first start, he beat the Kansas City Royals 3-1.’
