The National Science Foundation (NSF) funded a report from the National Academies' National Research Council (NRC) that concludes that high school students have shoddy science lab experiences. The study suggested that labs needed to be 'included in science education, designed with clear learning outcomes in mind, be interactive, and include learning about the scientific process.' The study adds fodder to the call for US schools to step up efforts to increase competiveness and understanding in math and science.
"In an increasingly complex, high-tech society, U.S. high school graduates need a basic understanding of science and technology to lead productive lives, the report says. To improve their understanding, most science laboratory experiences must be reformed."
Of course improving science education is complicated by school funding challenges, and confusion about which science curricula to teach.
You have to consider the liability issue. With colleges cranking out lawyers faster than pillsbury makes doughbouys, there are going to be plenty of them ready to hit any HS that spills hydogen dioxide on a kid. I'm suprised that schools let the them do any labs at all. Even disection runs the risk of offending vegans
