IMPLEMENTASI MODEL PROBLEM BASED LEARNING BERBANTUAN BUKU SAKU DIGITAL UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS PESERTA DIDIK: IMPLEMENTASI KURIKULUM MERDEKA

IMPLEMENTATION OF PROBLEM BASED LEARNING MODEL ASSISTED BY DIGITAL POCKET BOOK TO IMPROVE STUDENTS' CRITICAL THINKING SKILLS: IMPLEMENTATION OF THE MERDEKA CURRICULUM

Penelitian ini bertujuan untuk mendeskripsikan hasil keterlaksanaan model PBL berbantuan buku saku digital untuk meningkatkan keterampilan berpikir kritis peserta didik, mendeskripsikan peningkatan keterampilan berpikir kritis setelah implementasi model PBL berbantuan buku saku digital, dan mendeskripsikan respon peserta didik. Jenis penelitian ini adalah deskriptif kuantitatif dengan metode true experiment. Subjek penelitian ini adalah kelas X sebanyak 105 peserta didik. Desain penelitian ini adalah randomized subject control-group pretest and posttest design dengan rancangan penelitian yaitu pretest posttest control group design. Instrumen penelitian yang digunakan yaitu lembar keterlaksanaan, lembar pretest dan posttest, dan lembar angket respon. Data yang didapatkan diuji dengan menggunakan lembar analisis observasi keterlaksanaan, uji prasyarat yang meliputi uji normalitas dan uji homogenitas, lalu dilakukan uji beda menggunakan Wilcoxon Signed Rank Test lalu melakukan uji N-gain dan effect size dan lembar analisis angket respon. Berdasarkan analisis data didapatkan kesimpulan bahwa keterlaksanaan pembelajaran menggunakan model PBL berbantuan buku saku digital (PhyPo) terlaksanakan dengan sangat baik. Peningkatan keterampilan berpikir kritis pada kelas eksperimen 1 setelah diberi implementasi model PBL berbantuan buku saku digital berada pada kategori sedang. Implementasi model PBL berbantuan buku saku digital (PhyPo) untuk meningkatkan keterampilan berpikir kritis mendapatkan respon yang sangat baik dan dapat dijadikan sebuah inovasi dalam pembelajaran fisika.

Kata Kunci: Model pembelajaran problem based learning, buku saku digital, dan keterampilan berpikir kritis.

This study aims to describe the results of the implementation of the digital pocketbook-assisted PBL model to improve students' critical thinking skills, describe the improvement of critical thinking skills after the implementation of the digital pocketbook-assisted PBL model, and describe the response of students. This type of research is descriptive quantitative with true experiment method. The subjects of this study were class X as many as 105 learners. This research design is randomized subject control-group pretest and posttest design with a research design, namely pretest posttest control group design. The research instruments used are implementation sheets, pretest and posttest sheets, and response questionnaire sheets. The data obtained were tested using an observation analysis sheet of implementation, prerequisite tests which included normality tests and homogeneity tests, then different tests were carried out using Wilcoxon Signed Rank Test then perform N-gain and effect size tests and response questionnaire analysis sheets. Based on data analysis, it was concluded that the implementation of learning using the PBL model was assisted by digital pocketbooks (PhyPo) very well executed. The improvement of critical thinking skills in experimental class 1 after being given the implementation of a digital pocketbook-assisted PBL model was in the medium category. The implementation of the digital pocketbook-assisted PBL model (PhyPo) to improve critical thinking skills received a very good response and can be used as an innovation in physics learning.

Keywords: Problem-based learning model, digital pocketbook, and critical thinking skills.
