Science Daily—American teens are confident they can invent solutions to some of the world's pressing challenges，such as protecting and restoring the natural environment，but more than half feel unprepared for careers in Technology and engineering，the Lemelson-MIT Invention Index has found this Lemelson-MIT Invention Index，which assesses Americans' attitudes toward invention and innovation，also found there is an important need for more project-based learning in high schools．

Nearly three out of four American teens believe technological inventions or innovations can solve some of our pressing environmental issues within the next decade，including global warming，water pollution and fossil fuel depletion（消耗）．Nearly two-thirds of teens are confident they could invent some of these solutions．This contrasts with only 38 percent of adults who believe they could invent something to help protect and restore the natural environment．Of those adults，more than half are 18-24 years old．

“Today's teens are inheriting our society's environmental challenges，so their confidence and optimism that the problems are solvable is promising and exciting，” said Josh Schuler，executive director of the Lemelson-MIT Program，a non-profit organization at the Massachusetts Institute of Technology whose mission is to recognize outstanding inventors，encourage sustainable new solutions to real-world problems，and enable and inspire young people to pursue creative lives and careers through invention．“However，we owe our youth the tools they will need to solve these challenges．”

The Lemelson-MIT Invention Index found that more than half of American teens do not believe their high school is preparing them adequately for a career in technology and engineering．“Learning to invent is really no different than learning to swim or play the trombone（长号），” said Schuler，“It takes practice．Students need the opportunity to get their hands dirty and invent．Generally speaking，there’s not enough ‘learning by doing’ taking place in today's high schools，and our survey found that students recognize this．”
