Related Claims¶

• Asking questions is a valued scientific practice: all 23 experts agreed it is a key aspect of scientific research — related
• Descriptive expert-like response percentages on the CLASS survey were lower for the experimental group than the control group at post-test, despite the significant ANCOVA result — related
• Distinguishing classroom and research contexts in survey questions was a key outcome of student validation interviews — related
• Students show a large epistemological split between classroom and research contexts on thinking up their own questions
• Survey participation was low in about half of administered classes, with only 20 of 45 classes exceeding 40% matched pre/post response
