As children head back to school savvy teachers are looking for the best ways to help students maximise their learning potential.

Laptops are replacing traditional notebooks and educators are using technology to provide individualised instruction and online tutoring, which can add variety and help students to learn better.

"It's an exciting time to be in education because we are no longer looking for one method," Kris Enright, executive director of the Professional Association of Colorado Educators, said.

"Now, with the opportunity to meet individual needs, schools are becoming more diverse."

Mr Enright added that the ability to address student needs with a variety of tools is key to good instruction and effective learning.

Tutor.com, a company based in New York City, served 750,000 online students last year. This year it expects to help more than a million, George Cigale, founder of the site said.

Tutor.com has a network of 1,800 certified teachers, college professors, undergraduates and graduate students in the US and Canada from accredited universities.

"The vision from the early days eight years ago was to make it possible for a student to connect ... whenever they are stuck, and every time they need help overcoming an educational challenge," Mr Cigale said.

The use of online tutors who meet government-approved academic standards is supported by the US Department of Education for supplemental educational services under its No Child Left Behind Act.

"The department believes that online tutoring is an important option for students eligible for supplemental educational services that live in rural areas or have other challenges accessing a traditional tutoring programme," Morgan Brown, assistant deputy secretary in the Department of Education's Office of Innovation and Improvement, said in an e-mail.

President George W. Bush signed the No Child Left Behind Act in 2002 in an effort to improve educational standards throughout the US.

Parents are always looking for additional ways to supplement their child's learning, according to Enright.

"If the student is actually learning and it's authentic, then it's effective," he added.
