Penelitian  ini  bertujuan  menghasilkan  sintaks/langkah  model  pembelajaran 
Creative  Problem  Solving  dengan  pendekatan  Open  Ended  terkait  kemampuan 
berpikir kreatif matematis yang valid dan praktis. Penelitian ini mengacu pada Borg 
& Gall dimulai dari penelitian dan pengumpulan data, perencanaan pengembangan 
desain produk awal, uji coba lapangan awal, dan revisi hasil uji coba lapangan awal. 
Subjek  penelitian  adalah  siswa  kelas  X  SMA  Negeri  9  Bandar  Lampung  tahun 
pelajaran  2020/2021.  Data  penelitian  diperoleh  melalui  observasi,  wawancara, 
angket, dan tes kemampuan berpikir kreatif matematis siswa. Teknik analisis data 
yang digunakan adalah statistik deskriptif. Hasil penelitian menunjukkan bahwa (1) 
sintaks  atau  tahapan  model  Creative  Problem  Solving  dengan  pendekatan  Open 
Ended  terkait  kemampuan  berpikir  kreatif  matematis  siswa  yang  meliputi 
pemberian masalah  open ended,  pencarian fakta, penemuan ide, penemuan solusi 
masalah,  presentasi  hasil,  serta  analisis  dan  penerimaan  solusi  telah  memenuhi 
kriteria valid dan praktis; (2) model Creative Problem Solving dengan pendekatan 
Open  Ended  pada  materi  Trigonometri  didukung  oleh  perangkat  pembelajaran 
berupa silabus, RPP, LKPD, dan  tes kemampuan berpikir kreatif yang  memenuhi 
kriteria valid dan praktis.

ABSTRACT
THE DEVELOPMENT OF CREATIVE PROBLEM SOLVING MODEL 
WITH AN OPEN ENDED APPROACH TO STUDENT'S
MATHEMATICAL CREATIVE THINKING ABILITY
By

This research aims to produce a syntax/steps of a Creative Problem Solving learning 
model with an open ended approach related to valid and practical mathematical 
creative thinking ability. This research refers to Borg & Gall starting from research 
and data collection, planning the development of initial product designs, initial field 
trials,  and  revising  the  results  of  initial  field  trials.  The  research  subjects  were 
students of grade  X  SMA Negeri 9 Bandar Lampung in the  2020/2021 academic 
year.  The  research  data  were  obtained  through  observation,  interviews, 
questionnaires, and tests of students' mathematical creative thinking ability. The 
data analysis technique used is descriptive statistics. The results showed that (1) the 
syntax/steps of the Creative Problem Solving model with an Open Ended approach 
which include providing open-ended problems, fact finding, idea finding, problem 
solutions finding, presenting results,  as well as  analyzing and accepting solutions 
that have met  valid and practical criteria; (2) the Creative Problem Solving model 
with an Open Ended approach on Trigonometry material is supported by learning 
tools  in  the  form  of  a  syllabus,  lesson  plans,  worksheets,  and  creative  thinking 
ability tests that meet valid and practical criteria.
