Teaching Double-slit Experiment with Modular Optical Experimental Instruments

The Modular Optical Experimental Instruments (MOEI) are newly-designed laboratory demonstration tools which integrate a whole set of optical devices on single board. instructors can easily bring the MOEI to classrooms and demonstrate phenomena projector screens. In order investigate impact instruction double-slit experiment, we investigated 134 undergraduate students with an open-ended experiment designing task. Primary Trait Analysis (PTA) score suggested that learning experiments had better performance in selecting equipment understanding nature science showed more engineering thinking. results also common misconception about width interference fringes, was helpful avoid it.
