PENGARUH PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) TERHADAP KEMAMPUAN MENGIDENTIFIKASI BENTUK BANGUN RUANG PESERTA DIDIK TUNARUNGU 

THE EFFECT OF THE APPLICATION OF PROBLEM BASED LEARNING (PBL) ON THE ABILITY TO IDENTIFY THE SHAPE OF BUILDING SPACE FOR DEAF STUDENTS

Problem Based Learning (PBL) pada era abad 21 penting untuk diterapkan karena peserta didik terlibat aktif di dalam aktivtas pembelajaran melalui sintaks pembelajaran. Tujuan penelitian ini adalah mengkaji adanya pengaruh penerapan model pembelajaran Problem Based Learning (PBL) terhadap kemampuan mengidentifikasi bentuk bangun ruang peserta didik tunarungu kelas 1 SDLB di SLB Negeri Gunungsari Bojonegoro yang berjumlah 10 orang. Jenis penelitian pre-eksperimen dengan rancangan penelitian menggunakan one group pretest-posttest. Data dikumpulkan dengan teknik tes dan dianalisis menggunakan uji non parametrik Wilcoxon (Uji W) dengan SPSS versi 29.00 for windows. Hasil penelitian menunjukkan adanya peningkatan nilai rata-rata keseluruhan sampel penelitian dari pre-test 40,63 menjadi 81,88 pada post-test dan p-value uji wilcoxon penelitian ini lebih kecil dari α (0,05) yakni α (0,04) sehingga “Ha diterima”. Maka dapat disimpulkan ada pengaruh signifikan dari penerapan model pembelajaran Problem Based Learning (PBL) terhadap kemampuan mengidentifikasi bentuk bangun ruang peserta didik tunarungu di SLB Negeri Gunungsari Bojonegoro.

Problem Based Learning (PBL) in the 21st century era is important to implement because students are actively involved in learning activities through learning syntax. The purpose of this research was to examine the influence of the application of the Problem Based Learning (PBL) on the ability to identify the geometric shapes of deaf students in class 1 SDLB at SLB Negeri Gunungsari Bojonegoro, totaling 10 people. This type of pre-experimental research with a research design using one group pretest-posttest. Data were collected by testing techniques and analyzed using the Wilcoxon non-parametric test (W test) with SPSS version 29.00 for windows. The results showed that there was an increase In the overall average value of the research sample from the pre-test 40.63 to 81.88 in the post-test and the p-value of the Wilcoxon test in this study was smaller than α (0.05), namely α (0.04 ) so “Ha is accepted”. So it can be concluded that there is a significant influence from the application of the Problem Based Learning (PBL) learning model on the ability to identify geometric shapes of deaf students at SLB Negeri Gunungsari Bojonegoro.
