     Called "The School of the Future" and created with help from software giant Microsoft, a recently-

opened public school in Philadelphia, US, is believed to be the first in the world to combine innovation

teaching methods with the latest technology. At this school, students work on wireless laptops, teachers

eschew traditional subjects for real-world topics and parents can track their children's work on the Internet.

     The school, which costs the school district $63 million to build, is free and has no entrance exams.

The 170 ninth-grade students were selected at random from l,500 applicants.

     Philadelphia School District Chief Executive Paul Vallas told students they would be observed by other

schools around the world. "You have become instant role models," Vallas said. "People are going to be

watching you."

     Students still sit in classrooms, but lessons rely heavily on information found on the Internet and on

interactive software. Students will be allowed to learn at their own pace. Homework is done on the computer

and sent to the teacher for grading and parents can access to the school's network to read the teacher's

feedback on their children's progress.

     Traditional education fails to teach students the skills of problem-solving, critical thinking and effective

communication, which they need to succeed in the 21st century, Principal Shirley Grover said in an interview.

"It's not about memorizing certain algebraic equations (代数方程式) and then presenting them in 8 test,"

Grover said. "It's about thinking how maths might be used to solve a quality of water problem or how it

might be used to determine whether or not we are safe in Philadelphia from the bird flu."

     David Terry, 14, said he was hoping to "turn over a new leaf" after discipline problems in his previous

school left him with an "average to really bad" academic record. "This is a great opportunity for me," he said.

"In other schools, I would not _____."
