Abstract
In this research study, the teacher takes improvement action by
implementing Problem Based Learning (PBM) in problem solving: lack of
problem solving ability, critical thinking ability and learning achievement. The
objectives of the research are: to describe improvement steps by using problembased learning methods for developing critical thinking ability, problem solving
ability, student’s achievement and identify the constraints during the process of
action implementation and the solution. This research was conducted using a
classroom action research method (CAR) which concluded in three cycles, and
each cycle consists of four steps of planning, implementation, observation, and
reflection. Data were analyzed descriptive qualitative. The result of the research
shows that (1) corrective action is done 80% based on PBM steps, (2) there is
improvement in problem solving ability about 19%, (3) there is an increase in
critical thinking ability about 18%, (4) there is an increase of learning
achievement about 5 points (5) There are time allocation, and students who are
less active in groups during the process of implementation of the action takes
place. This can be solved by teachers by allocating more up time and manage time
more effectively, focusing on important material, actively monitoring the
discussion process and motivating students to be actively involved. / Pada penelitian ini guru melakukan tindakan perbaikan dengan
mengimplementasikan Pembelajaran Berbasis Masalah (PBM) dalam mengatasi
masalah: kurangnya kemampuan memecahkan masalah, kemampuan berpikir
kritis, prestasi belajar. Tujuan penelitian yang dilakukan adalah: untuk
mendeskripsikan langkah – langkah perbaikan dengan menggunakan model
pembelajaran berbasis masalah dalam meningkatkan kemampuan berpikir kritis,
kemampuan memecahkan masalah dan prestasi belajar siswa dan mengidentifikasi
kendala- kendala selama proses pelaksanaan tindakan dan cara mengatasinya.
Penelitian ini dilakukan dengan menggunakan metode penelitian tindakan kelas
(PTK) yang dilakukan dalam tiga siklus, dan setiap siklus terdiri dari empat
langkah perencanaan, pelaksanaan, observasi, dan refleksi. Data dianalisis secara
deskriptif kualitatif. Hasil penelitian menunjukan bahwa(1) tindakan perbaikan
yang dilakukan mengikuti langkah – langkah PBM sebesar 84%, (2) terjadi
peningkatan dalam kemampuan berpikir kritis meningkat sebesar 19% (3) terjadi
peningkatan dalam kemampuan memecahkan masalah sebesar 18% (4) terjadi
peningkatan nilai prestasi belajar dari sebesar 5 poin (5) Adanya kendala yaitu
keterbatasan waktu, dan siswa yang kurang aktif dalam kelompok selama proses
pelaksanaan tindakan berlangsung . Hal ini dapat diatasi oleh guru dengan
mengalokasi waktu lebih baik lagi, berfokus pada materi penting, aktif memantau
proses diskusi dan memotivasi siswa untuk terlibat aktif.
