Abstract
Physics demonstrations are celebrated for enlivening lectures and anchoring understanding, yet remarkably little is known about how the choice of demonstration materials, namely, familiar household objects versus specialized laboratory equipment, may shape students’ affective evaluations. A total of 288 secondary and college students observed two resonance demonstrations—one using wine glasses as everyday focal objects and one using tuning forks as laboratory focal objects—and completed a survey requesting an overall preference (household/lab/no preference) and Likert ratings on seven perception items for each demonstration. Demonstration order was counterbalanced across class sessions to guard against sequence effects. Overall, students far more often preferred the wine-glass demonstration (58.3%) over the tuning-fork demonstration (14.9%), with 26.7% reporting no strong preference; this preference pattern was consistent across both secondary and college students and did not differ significantly between male and female students. Preference distributions were also independent of presentation order. Paired comparisons showed that the household demonstration was rated significantly higher in interestingness, novelty, relevance to daily life, and its ability to stimulate interest in science. Importantly, clarity of the phenomenon and self-reported support for understanding resonance did not differ significantly between the two demonstrations, supporting the interpretation that the preference for the household condition is not attributable to the phenomenon being easier to observe or the concept easier to grasp. The results are theoretically grounded in cognitive load and situated cognition frameworks to explain how material-based contextualization may enhance student engagement without increasing perceived cognitive burden. These findings suggest that a seemingly simple instructional design choice, i.e., using a recognizable household object as the focal material in a physics demonstration, can meaningfully enhance student engagement and perceived relevance without sacrificing conceptual clarity.
