Kids with ADHD, dyslexia and other learning difficulties along with their families and teachers are gathering at AT&T Park this month for one of the largest learning fairs of its kind in the country.

On April 16, approximately 2,500 people are expected to attend the third annual Education Revolution 2011 in a day of inspiration for the children who face these often misunderstood conditions.

A highlight for the kids will be a chance to play baseball at the park, home of the World Champion Giants. But many other activities are planned as well, including skating, art projects, a contest, a creative career fair and opportunities to meet professionals who share their challenges.

The adults, meanwhile, can hear speakers on many topics, including research and assistive technology, and attend a fair with some 100 resources for people with learning difficulties.

“We aim to empower them through community building and education, and let them know that differences can be a source of great strength,” says EdRev’s founder, Dewey Rosetti.

Featuring a theme of “Stand Up, Speak Out!,” this year’s event intends to help kids express what they are to others, says Laura Maloney, executive director of the Parents Education Network (PEN), which puts on the event.

PEN is a nonprofit that empowers students who have learning and attention difficulties, and helps them achieve academic success.

The event’s keynote speaker is Dr. Todd Rose, co-chair of Harvard University’s Mind, Brain and Education Institute. Rose, who himself has ADHD, dropped out of school with a .9 GPA and became a teenage dad before turning his life around.

Other speakers include high school and college students who will share their stories and give a peek into the challenging lives of students with learning differences. Some 600 kids from around the region and U.S. are expected to participate.

Spanish translation will be available through the San Francisco Unified School District and Support for Families of Children with Disabilities. Bay Area Parent is also among the event’s sponsors.

EdRev happens from 9 a.m. to 5 p.m. at the park, 801 Third St., San Francisco. Entrance is FREE for students and teachers, and $60 for other adults. Scholarships are available. For details, call 415-751-2237, visit parentseducationnetwork.org or register at edrevsf.org.
