In a pilot with 29 introductory radiation physics students, students reported that the pinch-and-spread gesture helped them feel wavelength and amplitude, with amplitude receiving the highest mean rating of 4.59¶

q2 · i? · design · r2

Pilot attitude survey in a class of 29 second-year medical imaging majors in an introductory radiation physics course in 2026, on a 1-to-5 scale. The article reports "the pinch-and-spread motion of the fingers helped them \"feel\" what wavelength is (mean 4.52)" and a 4.59 mean for amplitude; the survey measured perceptions, not understanding or achievement.

"All 29 students agreed that the pinch-and-spread motion of the fingers helped them "feel" what wavelength is (mean 4.52). The statement about feeling the amplitude received the highest mean of all, 4.59."

• The article argues that for quantities represented spatially, such as amplitude and wavelength, the hand itself moving in space may be a more natural control than a slider or input box — a broader claim this one bears on
• In the pilot, 93% of students found controlling the wave in the air natural and 86% reported feeling more engaged and focused than in regular learning — related
• Mentored inquiry with staged mechanistic sensemaking supports the transition from intuitive to formal equation reasoning — related
