The Department of Education was also criticized for proposed lesson plans distributed to accompany the speech, including a section — later changed — that asked students to write about how they could help the president.

Schools were not required to show the speech, and the White House posted an advance transcript on its Web site on Monday. After they got a look at the text, many critics, including Greer, backed off, and some schools agreed to show the speech after all.

Still, others were glad they kept their kids out of class.

"They don't need to be told by the president what their responsibilities are. It's the parents' responsibility to teach them that, not the government," said Ryan Christensen, a carpet cleaner who asked that his 10-year-old daughter be pulled from a fifth-grade class watching the speech in Caldwell, Idaho.

In Marietta, Ga., the elementary school that Mollie Cushing's two daughters attend chose not to air the president's address. And that was just fine with Cushing.

The uproar followed Obama to Wakefield High School in Arlington, Va., where he delivered the speech. A small band of protesters greeted his motorcade when it arrived at the school outside the nation's capital. One carried a sign reading: "Mr. President, stay away from our kids."

Karen Miller, a former PTA official and a longtime education activist in the Houston area, said she initially had concerns about the speech and accompanying lesson plans. "Whenever a political figure goes to a public school, one has to be very cautious," she said.

After hearing the speech, however, Miller said she found it inspiring.

"The message he gave to children was so appropriate, that you shape your destiny no matter the hand you're dealt," she said. "The message was absolutely on target. I had chills."

All schools in the 163,000-student Philadelphia district were encouraged to show the speech, which coincided with the first day of school.

Missouri Lt. Governor Peter Kinder, a Republican, had originally criticized the speech and its suggested lesson plans as "steps never before seen by any presidency in the realm of government intervention." But he said his concerns eased after some of the lesson plans were changed.

"It was perfectly innocuous and a praiseworthy message," he said Tuesday.

At Thomas Jefferson High School in Auburn, Wash., a racially and economically diverse district outside Seattle, sophomores listened attentively to the address. Fifteen-year-old Ariana Steele said the message connected with her.

"When you see someone of such power saying what your parents say or your teachers have said, like all your life, it really makes it more powerful to you and it really makes you want to try more," she said.

And William Geist, a San Francisco fifth-grader who likes to sleep late, listened closely to Obama's story of studying with his mother at 4:30 a.m.

"Now since I heard this speech, I'm like, 'Man, I've got to get up early in the morning. I've got to get ready for school. I've got to do this,'" William said.
