Meskipun ilmu fisika merupakan salah satu ilmu yang sangat penting dalam pengembangan teknologi saat ini namun di mata mayoritas peserta didik masih dianggap sebagai ilmu yang sulit dan tidak menarik. Hal ini kemungkinan disebabkan oleh masih banyaknya guru yang hanya menerapkan metode ceramah ketika proses belajar mengajar fisika. Alternatif untuk mengatasi permasalahan tersebut adalah diterapkannya praktikum agar peserta didik dapat memiliki pengalaman langsung terkait konsep fisika yang ada. Namun, beberapa sekolah di Bangka tidak memiliki fasilitas laboratorium yang memadai sehingga kegiatan praktikum tidak dapat berjalan dengan baik atau bahkan tidak dapat dilaksanakan. Pada program pengabdian kepada masyarakat ini, dilakukan pelatihan penggunaan perangkat lunak PhET sebagai solusi laboratorium virtual. Penggunaan laboratorium virtual selain efisien dari segi biaya juga mudah untuk dilakukan dan memungkinkan peserta didik melakukan praktikum virtual secara mandiri. Setelah dilakukan kegiatan pelatihan mayoritas peserta memberikan respon positif terhadap penggunaan PhET dalam proses belajar mengajar. Selain itu, perangkat lunak PhET mudah digunakan.
