Dr. Halamka is the chief information officer at the Harvard Medical School, a practicing emergency-ward physician and an adviser to the Obama administration on electronic health records.

Hybrid careers like Dr. Halamka’s that combine computing with other fields will increasingly be the new American jobs of the future, labor experts say. In other words, the nation’s economy is going to need more cool nerds. But not enough young people are embracing computing — often because they are leery of being branded nerds.

Educators and technologists say two things need to change: the image of computing work, and computer science education in high schools. Teacher groups, professional organizations like the Association for Computing Machinery and the National Science Foundation are pushing for these changes, but so are major technology companies including Google, Microsoft and Intel. One step in their campaign came the week of Dec. 7, National Computer Science Education Week, which was celebrated with events in schools and online.

Today, introductory courses in computer science are too often focused merely on teaching students to use software like word processing and spreadsheet programs, said Janice C. Cuny, a program director at the National Science Foundation. The Advanced Placement curriculum, she added, concentrates narrowly on programming. “We’re not showing and teaching kids the magic of computing,” Ms. Cuny said.
