Dalam kegiatan ini, demonstrasi sistem PVD 3D dilaksanakan di Ming Chi University of Technology (MCUT) dengan melibatkan 10 peserta (n = 10) untuk meningkatkan pemahaman mereka mengenai teknologi pelapisan vakum. Melalui kegiatan praktik langsung, peserta memperoleh pengetahuan mengenai komponen sistem, persyaratan instalasi, sistem vakum, prosedur keselamatan, dan keseluruhan proses pengaturan sistem. Survei terstruktur untuk menilai pemahaman yang dilaporkan oleh peserta sendiri (self-reported understanding) dilakukan segera sebelum dan setelah demonstrasi. Rata-rata pemahaman yang dilaporkan sendiri meningkat dari 16,7% pada survei sebelum demonstrasi menjadi 93,3% pada survei setelah demonstrasi, yang menunjukkan peningkatan (knowledge gain) sebesar 76,6 poin persentase. Lebih dari 80% peserta melaporkan pemahaman yang komprehensif terhadap seluruh topik yang dievaluasi setelah kegiatan. Hasil ini menunjukkan bahwa demonstrasi tersebut berkaitan dengan peningkatan yang signifikan dalam pemahaman peserta yang dilaporkan sendiri mengenai teknologi PVD 3D.
