Another 2004 study of the "Eddie Eagle" program, published by North Dakota State University's Department of Psychology, found that children were able to verbally repeat the program's message, but when they encountered a gun in a role-playing scenario, they were unable to put the skills to use.
The North Dakota study said one shortcoming of programs like "Eddie Eagle" was the absence of active learning approaches.
"Information-based programs are less successful because they do not actively allow the children the opportunity to practice the skills being taught," the study said.
Former police investigator and gun safety expert Steve Albrecht said "kids don't have the emotional maturity at that age."
Albrecht is a security consultant for schools and workplaces and is also a parent. He said schools have to play a bigger role in the gun safety discussion but "in concert with the parents."
"Part of the issue has to be educating the parents to keep the guns secure first. Because it doesn't matter if the kids have been to a gun safety program or not," said Albrecht.
Patton agrees. She said the responsibility behind gun safety lies with parents and not with teachers.
But LaPierre told the Senate in January that "teaching safe and responsible gun ownership works" and stressed that firearms accidents are at their lowest levels in more than 100 years because of safety programs like "Eddie Eagle."
Brown said first-graders shouldn't be doing experiential learning with guns and felt the "Eddie Eagle" video would be enough.
