Abstract

Hasil belajar yang kurang maksimal menunjukkan kemampuan berpikir kritis siswa yang kurang maksimal pula. Salah satu model pembelajaran yang dapat meningkatkan kemampuan berpikir kritis siswa adalah problem based learning. Tujuan penelitian ini untuk mengetahui pengaruh model problem based learning terhadap kemampuan berpikir kritis siswa pada materi sistem ekskresi. Sampel yang digunakan adalah kelas XI IPA 1 sebagai kelas eksperimen dan kelas XI IPA 2 sebagai kelas kontrol. Penelitian quasi eksperimental ini menggunakan posttest only control design. Variabel yang diukur adalah kemampuan berpikir kritis siswa yang diperoleh dari skor posttest yang diuji korelasi biserial dan uji-t. Aktivitas siswa, tanggapan siswa, dan tanggapan guru dianalisis menggunakan analisis deskriptif kualitatif persentase. Berdasarkan hasil penelitian, rata-rata skor kemampuan berpikir kritis kelas eksperimen adalah 76,93 sedangkan kontrol adalah 65,67. Hasil uji-t menunjukkan bahwa terdapat pengaruh yang signifikan antara pembelajaran biologi model Problem Based Learning terhadap kemampuan berpikir kritis siswa di SMAN 1 Singorojo. Hasil uji korelasi biserial menunjukkan bahwa pembelajaran biologi model Problem Based Learning memiliki hubungan yang kuat terhadap kemampuan berpikir kritis siswa. Analisis aktivitas siswa secara deskriptif menunjukkan bahwa kelas ekskperimen lebih tinggi dibandingkan kelas kontrol. Simpulan dari penelitian ini adalah pembelajaran biologi model problem based learning berpengaruh meningkatkan kemampuan berpikir kritis siswa. Students’ achievement which is not maximal can show that their critical thinking skill is not maximal too. One of learning model that can improve students’ critical thinking skills is problem based learning. This study aims to determine the effect of problem based learning to students critical thinking skills on the excretory system. Samples of this study were XI IPA 1 as an experimental class and XI IPA 2 as the control class. This is a quasi-experimental research with posttest only control design. Variable that measured are students critical thinking skills obtained from the posttest scores than analyzed with biserial correlation and t-test. Students’ activity, students and teacher responses were analyzed by descriptive qualitative percentage. Based on the result, critical thinking skills average scores of experimental class was 76,93, while the control class was 65,67. The result of t-test showed that there is a significant influence between biology learning model of problem based learning to the students’ critical thinking skill at SMAN 1 Singorojo. Biserial correlation test showed that biology learning model of problem based learning have a strong relationship to the students’ critical thinking skills. Students’ activity analyzed showed that experimental class is higher than control class. The conclusion of this research is biology learning model of problem based learning have a effect there is increase students’ critical thinking skills.

Abstract

The study aims to describe the validity, applicability, and effectiveness of the developed learning aids. This research is a research and development (RD) research that uses the Borg and Gall model. The subjects of the wide-scale trial were 106 students of class XI at SMAN 16 Semarang. The data analysis used was descriptive percentages.  The results and conclusions of this study indicate that: (1) overall learning aids are highly valid based on expert validation, and construct validity, especially for tests of critical thinking skills obtained valid and reliable results (2) learning aids are well implemented; (3) learning aids effectively improve students' critical thinking skills with 75% of students meeting the minimum completion criteria, and regarding N-gain test, there is an increase in critical thinking skills with moderate criteria.  The STEM-PjBL Learning aids effectively trains the ability to think creatively, communicatively and collaboratively with high criteria.

Abstract

The purpose of this study was to analyze the effectiveness of STEM-PjBL learning on students' critical thinking, creative thinking, communication, and collaboration (4C) skills. This research is quantitative with a one-group pretest-posttest design. The research samples were 106 class XI State Senior High School 16 Semarang students. Quantitative data on critical thinking skills were analyzed using the N-gain test, while other data were analyzed descriptively. The results showed increased students' critical thinking skills based on the N-gain test. The paired sample t-test results in the SPSS 28 program obtained a significance value/Sig. (2-tailed) of 0.001, there were differences in critical thinking skills before and after STEM-PjBL learning. STEM-PjBL learning effectively trained students' creative, collaborative, and communicative thinking skills with high categories. This learning effectively trained students' critical thinking, creative thinking, communication, and collaboration skills

Abstract

Komunikasi dan kolaborasi adalah dua elemen penting yang memungkinkan peserta didik meraih hasil optimal dalam proses pembelajaran pada abad ke-21. Oleh karena itu, perlu dirancang pembelajaran yang dapat membekali peserta didik dengan keterampilan tersebut agar mampu terus mengembangkan dirinya di abad ke-21.  Penelitian ini bertujuan untuk menganalisis kemampuan komunikasi dan kolaborasi mahasiswa pada penerapan pembelajaran Problem Based Learning (PBL) berbasis Education for Sustainable Development (ESD). Penelitian ini merupakan penelitian kuasi eksperimen dengan desain one-group posttest-only design yang dilakukan pada mahasiswa Pendidikan IPA semester I Tahun Akademik 2023/2024 yang berjumlah 21 orang. Data kemampuan komunikasi dan kolaborasi mahasiswa diperoleh melalui observasi dan dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa kemampuan komunikasi mahasiswa berada pada kategori tinggi dengan skor rata-rata 0,73 dan kemampuan kolaborasi mahasiswa berada pada kategori tinggi dengan skor rata-rata 0,79. Hasil dari penelitian ini mengindikasikan bahwa model Problem Based Learning berbasis ESD efektif untuk melatih kemampuan komunikasi dan kolaborasi mahasiswa.
