Description
This study explores how physics teachers from undergraduate colleges in India develop sense-making abilities while using a photogate to measure the period of a bar pendulum's oscillation. Thirty-five participants arranged experimental setup and analyzed data to overcome challenges like measurement discrepancies caused by asymmetry. Teachers initially struggled to interpret observations but later recognized the importance of symmetric configurations and full oscillation setups for accurate measurements. Discussions highlighted the advantages of multiple oscillations and the superior repeatability of photogate results over manual stopwatch readings. The findings underscore the need for careful experimental design to enhance systematic thinking and reduce errors.
