President Barack Obama's plans for a televised back-to-school address to students next week are drawing fire from some conservatives, who say he's just trying to indoctrinate them to his political beliefs.

In the Sept. 8 speech, Obama will challenge students to work hard, set goals for their education and take responsibility for their learning, Education Secretary Arne Duncan said in a letter to principals.

The Education Department is encouraging teachers to create lesson plans around the speech, using materials provided on the department website that urge students to learn about Obama and other presidents.

"He will also call for a shared responsibility and commitment on the part of students, parents and educators to ensure that every child in every school receives the best education possible so they can compete in the global economy for good jobs and live rewarding and productive lives as American citizens," Duncan said in a press release.

But already, some conservatives are crying foul. The chairman of the Florida Republican Party is condemning Obama's speech as an attempt to "indoctrinate America's children to his socialist agenda."

"The idea that school children across our nation will be forced to watch the President justify his plans for government-run health care, banks, and automobile companies, increasing taxes on those who create jobs, and racking up more debt than any other President, is not only infuriating, but goes against beliefs of the majority of Americans, while bypassing American parents through an invasive abuse of power," Chairman Jim Greer said in a press release.

Added conservative talk show host Tammy Bruce, in a Twitter feed: "Make September 8 Parentally Approved Skip Day. You are your child's moral tutor, not that shady lawyer from Chicago." And conservative author Michelle Malkin said the lesson plans have a "heavy activist bent."

Texas school districts are discussing whether the president's speech will be shown — some districts are leaving it up to individual teachers with an opt out for parents who don't want their children to view the speech, according to the Houston Chronicle.

In his letter to principals, Duncan said viewing of the speech is encouraged, not mandatory. It's the first time a president has ever given a speech addressed directly to students.
