Tujuan dari penelitian ini adalah mendapatkan gambaran tentang pembelajaran berbasis proyek dalam pembiasaan berpikir kreatif mahasiswa calon guru matematika. Penelitian ini termasuk penelitian pengembangan dengan teknik analisis deskriptif kualitatif. Penelitian tersebut mengikuti tahapan identifikasi, pengembangan, dan penyebaran (Borg & Gall). Ujicoba dilakukan pada semester VI program studi pendidikan Matematika di STKIP Taman Siswa Bima. Pengumpulan data menggunakan instrumen lembar observasi, pedoman wawancara dan instrumen tes. Perangkat pembelajaran yang melalui tahap pengembangan, setelah dilakukan uji validasi dan ujicoba dapat dikatakan praktis dengan adanya penilaian validator yang menyatakan perangkat valid dan dapat dipergunakan setelah direvisi sesuai catatan, hasil observasi pelaksanaan pembelajaran setiap SAP pada kriteria baik, hasil observasi pembelajaran mahasiswa setiap SAP menunjukan aktif. Perangkat pembelajaran dikatakan efektif dengan adanya mahasiswa merespon positif pembelajaran setiap SAP, RTM dan instrumen tes hasil belajar memenuhi kriteria valid, reliabel dan sensitif serta ketuntasan belajar klasikal terpenuhi. The purpose of this study is to get an overview of project-based learning in the habit of creative thinking of teacher and students perspective of mathematics. This research included development research with qualitative descriptive analysis. The study follows the stages of identification, development, and dissemination (Borg & Gall). The trial was conducted in the sixth semester of Mathematics education program at STKIP Taman Siswa Bima. Data collection used observation sheet, in-depth interview and test. Learning device through development stage, after validation test and test can be said practically with the existence of validator assessment which stated device valid and can be used after the revised, the result of observation of learning implementation every Teaching Events Unit on a good criterion, the result of observation of students' learning in every Teaching Events Unit show active participation. Learning devices are said to be effective in the presence of students respond positively to learning each Teaching Events Unit, Student Duty Plan and test result learning instruments meet the criteria of valid, reliable and sensitive as well as completeness of classical learning fulfilled.
