This study investigates how evolution versus intelligent design is handled in the public, private Christian, private Jewish, and Christian Home-school K-12 settings through a review of the current literature and by interviewing teachers in these educational venues. Fourteen public, private, and homeschool educators responded to an interview protocol regarding how they incorporate critical thinking into the education of their students as it applies to the evolution versus intelligent design debate. Results indicated that there was actually more discussion about the debate happening in the private and homeschool setting, rather than in the public schools. However, public school teachers agreed that students should discuss these ideas within the social studies rather than in the science curriculum. There was a consensus among interviewees that students' critical thinking is lacking in regards to evolution versus intelligent design because today's curriculum leaves little time for student reflection and discussion. K-12 students in the United States could be presented with a balanced treatment of evolution and intelligent design in order to foster critical thinking in all educational settings -- public, private, and homeschool. The "Debate of Evolution v. Intelligent Design: Is Critical Thinking Occurring among K-12 Students?" interview and Informed Consent Form are appended.
