The NY Times, LA Times and many others criticized Heartland’s inept plan to hire David Wojick to create an alternate-reality K-12 climate science curriculum. But Heartland's school ground attack on science is nothing new, as is evident in the organization's own commentary: “Heartland has tried to make material available to teachers, but has had only limited success. Principals and teachers are heavily biased toward the alarmist perspective.”
One of the best known Heartland incursions into the schoolyard occurred in 2008, when the institute mailed teaching materials to 11,250 schools in Canada. In 2009, Science derided Heartland for sending copies of The Skeptic’s Handbook to 14,000 US school board officials. Heartland's Environment and Climate New mocked one school board president for his refusal to use it.
But Heartland began its classroom misinformation campaign much earlier. During 2002-2003, E&CN ran ads exhorting readers to “discuss an E&CN article with your school-age child… and his or her teacher.” I hope parents avoided the common “Smoker’s Lounge” ads in those issues.
