Subclaims¶

q2 i? Over 80% of students were able to predict and explain why the frequency of the gravitational wave increases with time during inspiral, while only about half deduced that the amplitude also increases. → Farr 2012

q2 · i? · design · r2

Classroom implementation across 8 mixed junior/senior, honors and non-honors classes of about 25 students. The authors report that "over 80% of students were able to predict and explain" the increasing frequency after the demonstration and guided inquiry worksheet; no statistical test is reported.

"We found that through the demonstration and the guided inquiry worksheet, over 80% of students were able to predict and explain why the frequency of the gravitational wave will increase with time as the binary system inspira ls."

Discussion¶

Related Claims¶

• Guidance during inquiry learning improves post-inquiry learning outcomes (d = 0.50) — the general claim this finding bears on, with the studies behind it

• Conflict-based instruction improves science conceptual learning, though staged contradictions helped only learners who reported being confused, and no study isolates disequilibrium as the mechanism — the general claim this finding bears on, with the studies behind it

• Instruction that confronts science misconceptions (conceptual-conflict interventions, refutation text) produces conceptual change more often than standard exposition — the general claim this finding bears on, with the studies behind it

• Mentored inquiry with staged mechanistic sensemaking supports the transition from intuitive to formal equation reasoning — related
• Adding prediction and discussion to lecture demonstrations significantly improves students' ability to explain the outcomes compared with merely observing — related
