摘要：Penelitian ini bertujuan untuk menghasilkan suatu produk pengembangan dalam
bentuk desain didaktis dan mengetahui kemampuan pemecahan masalah matematis
siswa. Data diperoleh dari wawancara, observasi dan tes kemampuan pemecahan
masalah. Berdasarkan hasil uji coba lapangan nilai rata-rata sebesar 74,2% dan tingkat
kelulusan 76,19%. Hasil tertinggi dari aspek pemecahan masalah adalah memahami
masalah 90,48% dan nilai terendah adalah memeriksa kembali sebesar 56,55%.
Kesimpulan penelitian ini bahwa hasil posttest menunjukkan indikator memahami
masalah sudah baik artinya siswa mampu memahami masalah dengan menuliskan apa
yang diketahui dan ditanyakan. Namun, pada indikator memeriksa kembali diperoleh
presentase terendah, karena siswa jarang memeriksa kembali jawaban yang telah
ditulis.
其他摘要：The research aims to create a developmental product in the form of didactical design in order to
know the students’ ability of mathematical problem solving. The data were obtained from
interview, observation, and problem solving skill test. Based on the results of field try-out, it
was obtained the mean score of 74% with achievement level of 76.19%. The highest problem
solving aspect was understanding the problem with the score of 90.48% and the lowest score
was rechecking skill with the score of 56.55%. Based on the findings, the posttest results show
that the indicator of understanding the problem is good, it means that the students are able to
understand the problem by writing what they know and what is being asked, but the indicator
of rechecking gets lowest presentation score because the students rarely recheck their written
answers.
