Mobilizing Minds: Teaching Math and Science in the Age of Sputnik
Beginning in 1958 with funds from the National Science Foundation, the Biological Sciences Curriculum Study (BSCS) developed three new high school curricula for that science. One (the green version) took an ecological approach, one (the blue version) emphasized the molecular basis of biological activity, and the third (the yellow version) focused on traditional systematic biology. All three approaches used apparatus like that found in research laboratories, but in a less expensive form. Teachers, some of whom had developed classroom material at their own schools, received training in the new curricula and continued to shape biology education.
