Concerning Paula Costis' letter (May 3), this is what I believe she really meant to write: "Teachers actually attempt to inform and educate students" ... of their own personal agendas regarding global warming.
As a teacher, if I had permission to show Al Gore's controversial movie, I would make sure to present both sides of the argument so students could make up their own impressionable minds. Isn't that education's goal, to help students learn to think for themselves?
I would show Gore's movie, followed by classroom discussion. The next day, I would show the British documentary, "The Great Global Warming Swindle," followed by a compare-and-contrast discussion. Then I would separate the class into "agree" and "disagree" groups, allow them to research further, followed by a presentation of their findings in debate format with an unbiased teacher as moderator. This would be a true learning experience, not some regurgitated rant of what a teacher "believes."
Having a child in elementary school, I would consider only this method of presenting the subject of global warming as acceptable. Any other method I would consider as bordering on teacher malpractice, promoting, as writer Michael Chrichton alleges, a false "State of Fear."
