Abstrak. Kesulitan melakukan pemecahan soal cerita bagi siswa sekolah dasar dapat menjadi kendala untuk menguasai domain matematika lainnya. Tujuan penelitian ini adalah melakukan validasi modul “FOPS’ untuk meningkatkan kemampuan pemecahan soal cerita matematika. Subjek penelitian ini terdiri dari 9 guru sekolah dasar yang memberikan penilaian terhadap validitas isi modul serta 53 siswa sekolah dasar di Yogyakarta. Hasil uji validitas isi modul dengan menggunakan Aiken’s V berada pada rentang nilai 0,889-0,962 pada sesi pembelajaran yang mengindikasikan memiliki validitas isi yang baik. Hasil uji empirik menunjukkan terdapat perbedaan skor perolehan posttest antara kelompok eksperimen dan kelompok kontrol (z= -3,735 ; p<0,001 ; <0,05). Hasil penelitian membuktikan bahwa modul “FOPS†valid untuk meningkatkan kemampuan pemecahan soal cerita pada siswa sekolah dasar.

Kata Kunci: Validasi Modul “FOPSâ€, Pemecahan Soal Cerita Matematika, Siswa.
