Kajian tindakan ini bertujuan meningkatkan penguasaan pengetahuan konseptual dan prosedural murid dalam menulis persamaan kimia yang seimbang melalui penggunaan simulasi digital. Kajian melibatkan 22 orang murid Tingkatan 4 yang dikenal pasti menghadapi kesukaran memahami konsep dan prosedur menulis persamaan kimia yang seimbang. Intervensi dilaksanakan selama dua minggu menggunakan simulasi digital PhET yang menekankan visualisasi interaktif dan penerokaan kendiri murid. Kajian ini menggunakan pendekatan campuran yang melibatkan pengumpulan data kuantitatif dan kualitatif. Data kuantitatif diperoleh melalui ujian pra dan ujian pasca bagi menilai perubahan tahap penguasaan murid, manakala data kualitatif dikumpulkan melalui pemerhatian, temu bual dan analisis lembaran kerja murid. Dapatan kajian menunjukkan skor ujian pasca meningkat antara 10% hingga 45% berbanding ujian pra, dengan peningkatan min skor keseluruhan daripada 55.9% kepada 78.9%. Peningkatan sebanyak 23.0% menunjukkan bahawa simulasi digital membantu meningkatkan penguasaan pengetahuan konseptual dan prosedural murid dalam menulis persamaan kimia yang seimbang. Pemerhatian selepas intervensi turut menunjukkan murid lebih aktif terlibat, mampu menjelaskan konsep dengan lebih tepat dan menunjukkan keyakinan semasa menulis persamaan kimia. Dapatan ini menunjukkan bahawa visualisasi interaktif membantu murid menghubungkan konsep abstrak dengan representasi simbolik kimia secara lebih bermakna. Implikasi kajian menunjukkan bahawa penggunaan simulasi digital berpotensi sebagai pendekatan pedagogi alternatif dalam pengajaran kimia bagi membantu pengajaran guru dan pembelajaran murid. Kesimpulannya, penggunaan simulasi digital merupakan pendekatan pengajaran yang berkesan kepada murid memahami konsep kimia yang abstrak serta meningkatkan kualiti pengajaran dan pembelajaran kimia di bilik darjah.References
