Abstract

This research aims to determine the mathematical creative thinking abilities of class VII students at SMPN 6 Siak Hulu. In this study, four indicators were used, namely fluency indicators, originality indicators, flexibility indicators, and elaboration indicators. In the learning carried out, especially in mathematics learning, students must have the ability to think creatively and mathematically. The ability to think creatively mathematically is the ability to think to find new ideas or thoughts in general or original with the aim of providing definite and precise results. The subjects in this research were 28 class VII students using qualitative descriptive methods. The instrument in this research used four essay questions and interviews on mathematical creative thinking abilities. The results of research on students' mathematical creative thinking abilities at SMPN 6 Siak Hulu obtained meager results. The average percentage for all indicators is 18%.

Abstract

Rendahnya kemampuan siswa dalam memecahkan masalah khususnya pada mata pelajaran matematika berdampak pada nilai matematika siswa yang masih banyak di bawah Kriteria Kekuntasan Tujuan Pembelajaran (KKTP). Penelitian ini bertujuan untuk melihat pengaruh model pembelajaran project based learning terhadap kemampuan pemecahan masalah matematis. Jenis penelitian yang digunakan dalam penelitian ini adalah jenis Quasi Eksperimental Design. Desain dalam penelitian ini menggunakan Nonequivalet Control Group Design. Pada penelitian ini yang menjadi populasinya adalah siswa Kelas X SMA Negeri 3 Pinggir. Sampel penelitian yaitu siswa kelas Xb sebagai kelas eksperimen dan siswa kelas Xa sebagai kelas kontrol dan jumlah sampel masing-masing kelas adalah 31 peserta didik. Instrumen yang digunakan dalam penelitian adalah soal tes kemampuan pemecahan masalah matematis. Data dianalisis menggunakan analisis statistik inferensial. Dimana data akan di uji normalitas melnggunakan uji shapiro-wik kemudian di uji homogenitas menggunakan uji levene. Setelah uji  prasyarat terpenuhi maka dilanjutkan dengan uji hipotelsis menggunakan uji independent sampel test. Berdasarkan hasil pelnellitian dan analisis data yang telah dilakukan, diperoleh nilai Sig.(2-taileld) sebesar 0.000 untuk post-telst kelas eksperimen dan kelas kontrol. Jadi, jika nilai Sig.(2-taileld) < 0.05 maka H1 diterima, belarti terdapat perbedaan yang signifikan antara rata-rata kemampuan pemecahan masalah matematis kelas eksperimen dan kelas kontrol. Dengan delmikian, dapat disimpulkan terdapat Pengaruh signifikan modell Project Based Learning terhadap kemampuan pemecahan masalah matematis siswa. Pelnellitian ini melnunjukan bahwa penerapan modell PjBL dapat meningkatkan kemampuan pemecahan masalah matematis siswa.
