PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING TERHADAP KEMAMPUAN CRITICAL THINKING SISWA PROGRAM KEAHLIAN TEKNIK PEMESINAN

APPLICATION OF LEARNING MODEL PROBLEM BASED LEARNING MODEL ON CRITICAL THINKING ABILITY STUDENTS OF ENGINEERING EXPERTISE PROGRAM MACHINERY

Pendidikan yang mendukung pembangunan di masa depan adalah pendidikan yang mampu mengelola dan memecahkan masalah pendidikan. Oleh karena itu, model PBL termasuk dalam salah satu implementasi kurikulum merdeka belajar. Model pembelajaran PBL berfokus pada masalah yang relevan bagi siswa, peran guru adalah menyajikan masalah, mengajukan pertanyaan dan mendorong penyelidikan dan dialog. Penelitian ini bertujuan untuk mengetahui hasil dari penerapan model pembelajaran Problem Based Learning terhadap kemampuan critical thinking siswa program keahlian teknik pemesinan dan respon belajar siswa terhadap penerapan model pembelajaran Problem Based Learning. Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan metode kuantitatif desain model Kemmis dan Mc. Taggart. Sampel dalam penelitian ini yaitu siswa kelas XI TPM 2 SMKN 3 Surabaya dengan jumlah 33 siswa. Pengumpulan data berupa tes subjektif, angket, dan dokumentasi. Analisis data dilakukan uji parametrik, N-Gain skor dengan menggunakan software spss statistic 26 dan skala likert. Hasil menunjukkan terdapat peningkatan kemampuan critical thinking siswa sebesar 24% setelah penerapan PBL pada siklus I dan II, dengan N-Gain score meningkat dari 31% pada siklus I menjadi 63,7% pada siklus II. Hal ini terjadi karena adanya tahap refleksi yang digunakan untuk menganalisis kekurangan yang terjadi pada siklus sebelumnya dan mencari solusi dari permasalahan tersebut, sehingga pada siklus selanjutnya pembelajaran akan menjadi lebih efektif. Serta respon dari siswa terhadap penggunaan model problem based learning dengan mendapatkan nilai skor sebesar 89% termasuk dalam kategori sangat baik.

Education that supports future development is education that is able to manage and solve educational problems. Therefore, the PBL model is included in one of the implementations of the independent learning curriculum. The PBL learning model focuses on problems that are relevant to students, the teacher's role is to present problems, ask questions and encourage investigation and dialog. This study aims to determine the results of the application of the Problem Based Learning learning model on the critical thinking skills of students in the machining engineering expertise program and student learning responses to the application of the Problem Based Learning learning model. This research is a classroom action research (PTK) with a quantitative method of Kemmis and Mc model design. Taggart model design. The sample in this study were students of class XI TPM 2 SMKN 3 Surabaya with a total of 33 students. Data collection in the form of subjective tests, questionnaires, and documentation. Data analysis was carried out parametric test, N-Gain score using spss statistic 26 software and Likert scale. The results showed that there was an increase in students' critical thinking skills by 24% after the application of PBL in cycles I and II, with the N-Gain score increasing from 31% in cycle I to 63.7% in cycle II. This happened because of the reflection stage which was used to analyze the shortcomings that occurred in the previous cycle and find solutions to these problems, so that in the next cycle the learning will be more effective. As well as responses from students to the use of problem-based learning models by getting a score of 89% including in the very good category.
