Abstract

Abstract. This study aims to determine the improvement of student’s problem solving skill after applying the problem based learning model and determine it’s effectiveness. This is a quantitative research with one group pretest-posttest design. Cluster random sampling was used, and 28 samples were obtained from one of high schools in Samarinda. The result of the analysis with Wilcoxon Signed Rank Test. The result showed that there’s a significant difference between students’ problem solving skill before and after the treatment, with the ­p-value 0,00 with significance 0,05. Generally, students’ problem solving skill increased from 8.5 to 29.5, with N-Gain of 0,2, which is classified as a low category. The highest gain was found in the ability of understanding the problem, with the ­N-Gain of 0,4, which is classified as a middle category. Meanwhile the indicator of students’ skill on planning problems, solving problems, and doing the re-check, were classified as low increasing category with N-Gain of 0,2. Based on calculation of effect size (d), which is 1,96 that is classified as a big category, the implementation of the treatment had a high effectiveness.   Keywords : Problem Based Learning, Problem Solving Skill, Simple Harmonic MotionAbstrak. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan pemecahan masalah siswa setelah diterapkan model problem based learning dan mengetahui tingkat efektifitas dari penerapan model tersebut. Penelitian ini merupakan penelitian kuantitatif dengan desain one group pretest-posttest. Teknik pengambilan sampel yang digunakan adalah cluster random sampling, dengan sampel sebanyak 28 siswa dari salah satu sekolah SMA di Samarinda. Data dianalisis menggunakan Wilcoxon Signed Rank Test. Hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan antara kemampuan pemecahan masalah siswa saat pretest dan posttest dengan perolehan p-value 0,00 dan signifikansi 0,05. Rata-rata kemampuan pemecahan masalah siswa mengalami kenaikan dari 8,5 menjadi 29,5 dengan N-Gain 0,2 yang termasuk dalam kategori rendah. Peningkatan tertinggi diperoleh indikator memahami masalah dengan N-Gain 0,4 yang termasuk dalam kategori sedang, sedangkan indikator kemampuan siswa merencanakan masalah, menyelesaikan masalah dan melakukan pengecekkan kembali termasuk dalam kategori rendah dengan N-Gain 0,2. Tingkat efektivitas yang diperoleh termasuk dalam kategori tinggi dengan nilai effect size (d) 1,96 yang termasuk dalam kategori besar.Kata Kunci : Problem Based Learning, Kemampuan Pemecahan Masalah, Gerak Harmonik Sederhana

Abstract

Abstract. The purpose of this study was to determine the project performance of students and improve the creative thinking skills of high school students after being taught project-based learning. The population in this study were all students of eleventh grade of State Senior High School 8 (SMAN 8) Samarinda in the academic year of 2018/2019. The samples taken were students of eleventh grade MIPA 1(n=36 students) and MIPA 2(n=36 students). This type of research was a quasi-experimental study with a nonequivalent control group design. Data collection is done by using observation and written test techniques. The results of the analysis with a Mann Whitney test showed that there’s a significant differences between students’ creative thinking skills of the experimental class which applied project-based learning and the control class which applied conventional learning with the p-value 0.00. Generally, students’ creative thinking skills increased with N-Gain 0.6, middle category. The results of research on project performance amounted to 86.2 which is categorized as an excellent category. Keywords: project based learning, creative thinking skills, project performance Abstrak. Penelitian ini bertujuan untuk mengetahui kinerja proyek siswa dan peningkatan keterampilan berpikir kreatif siswa SMA setelah diajarkan pembelajaran berbasis proyek. Populasi penelitian ini adalah seluruh siswa kelas XI SMA Negeri 8 Samarinda tahun ajaran 2018/2019. Sampel penelitian adalah siswa kelas XI MIPA 1(n = 36 Siswa)  dan XI MIPA 2 (n=36 Siswa). Jenis penelitian ini adalah penelitian kuasi-eksperimen dengan rancangan nonequivalent control group. Pengumpulan data dilakukan dengan menggunakan teknik observasi dan tes tertulis. Hasil analisis melalui uji Mann Whitney menunjukkan terdapat perbedaan yang signifikan antara keterampilan berpikir kreatif siswa kelas eksperimen yang diterapkan pembelajaran berbasis proyek dengan kelas kontrol yang diterapkan pembelajaran  konvesional dengan p-value 0,00. Rata-rata keterampilan berpikir kreatif siswa mengalami kenaikan dengan N-Gain 0,6; kategori sedang. Hasil penelitian kinerja proyek sebesar 86,2 yang termasuk dalam kategori sangat baik. Kata Kunci :  project based learning, keterampilan berpikir kreatif, kinerja proyek

Abstract

Abstract. This research was conducted to improve critical thinking skills students through the application of the Project Based Learning (PBL) model on the material of simple harmonic motion. The research design was a quasi-experimental study with a control group pretest posttest design. The research was conducted at a high school in Samarinda with the number of research subjects consisting of 34 students. The instruments of the research were in the form of an integrated test description with skills critical thinking and a questionnaire of the student responses to the application of the PBL model. The result of the research showed that the of the PBL model (experimental class) improved students' critical thinking skills with N-Gain means of 0.61, while the conventional model (control class) improved students' critical thinking skills with N-Gain means of 0.38. There is a significant difference in critical thinking skills between classes using the PBL model compared to those applying the conventional model on the topic of simple harmonic motion.Keywords: problem based learning, critical thinking, simple harmonic motion.Abstrak. Penelitian ini dilakukan untuk meningkatkan keterampilan berpikir kritis siswa melalui penerapan model Project Based Learning (PBL) pada materi gerak harmonik sederhana. Desain penelitian ini adalah kuasi eksperimen dengan control group pretest posttest design. Penelitian dilakukan pada salah satu SMA di Samarinda dengan jumlah subjek penelitian terdiri dari 34 siswa orang siswa. Instrumen penelitian berupa tes uraian yang terintegrasi dengan keterampilan berpikir kritis dan angket tanggapan siswa terhadap penerapan model PBL. Hasil penelitian menunjukkan bahwa penerapan model PBL (kelas eksperimen) meningkatkan keterampilan berpikir kritis siswa dengan rerata N-Gain sebesar 0,61, sedangkan untuk model konvensional (kelas control) meningkatkan keterampilan berpikir kritis siswa dengan rerata N-Gain sebesar 0,38. Terdapat perbedaan kterampilan berpikir kritis yang signifikan antara kelas dengan menerapkan model PBL dibandingkan dengan yang menerapkan model konvensional pada topik gerak harmonik sederhana.Kata kunci: problem based learning, berpikir kritis, gerak harmonik sederhana.
