I examine the levels of educational emphases that science teachers in Evangelical Protestant (EP) schools place on (i) teaching basic content knowledge, (ii) improving scientific reasoning skills, and (iii) presenting real-world applications of science. Using a nationally representative sample of US ninth-graders, I find differences in these educational emphases between science teachers in EP schools and science teachers in secular private, Catholic, and public schools. I also find suggestive evidence that differences in STEM-related student outcomes across school sectors, which have been demonstrated in prior research, are associated with cross-sector differences in the emphases of science teachers.
