Abstract

Ilmu pengetahuan yang berkembang menuntut siswa untuk belajar lebih bervariasi, hal ini dapat diperkaya dengan meningkatkan kemampuan berpikir kritis siswa. Penelitian bertujuan untuk mendeskripsikan keterlaksanaan, menganalisis kemampuan berpikir kritis siswa, menganalisis pengaruh model pembelajaran Numbered Head Together (NHT) berbantu media kokami terhadap kemampuan berpikir kritis siswa pada materi sistem ekskresi, dan mendeskripsikan respon siswa. Metode penelitian yang digunakan adalah kuasi eksperimen dengan desain penelitian Non-equivalent Control Group Design. Teknik pengambilan sampel yang digunakan purposive samplin dengan jumlah 30 siswa pada kelas eksperimen dan 30 siswa pada kelas kontrol. Instrumen penelitian berupa soal pilihan ganda sejumlah 20 butir soal pada pretest dan posttest. Hasil penelitian kelas eksperimen menunjukan rata-rata nilai keterlaksanaan siswa dan guru 96,9% dengan kategori sangat baik. Adapun pada kelas kontrol rata-rata nilai keterlaksanaan siswa dan guru 100% dengan kategori sangat baik. Hasil analisis menunjukkan nilai rata-rata N-Gain pada kelas eksperimen sebesar 0,63 dan 0,4 pada kelas kontrol dengan kategori sedang. Respon siswa terhadap pembelajaran menggunakan model NHT berbantu media kokami dengan rata-rata 77,5% pada kategori cukup. Hasil analisis uji t memperoleh nilai thitung 7,475 > ttabel 1,671 pada taraf signifikansi 0,05 maka dapat disimpulkan bahwa model pembelajaran Numbered Head Together (NHT) berbantu media kokami berpengaruh positif terhadap kemampuan berpikir kritis siswa pada materi sistem ekskresi. ABSTRACT Siti Zahra Fatimah:”The Influence of Learning Models Numbered Head Together (NHT) Assisted by Mysterious Card Box Media (KOKAMI) Against Students' Critical Thinking Ability in Material Excretion System” Developing science requires students to learn more varied, this can be enriched by increasing students' critical thinking skills. The research aims to describe implementation, to analyze students' critical thinking skills, to analyze the influence of learning models Numbered Head Together (NHT) assisted by Kokami media on students' critical thinking skills on excretory system material, and describing student responses. The research method used is a quasi-experimental research designNon-equivalent Control Group Design. The sampling technique usedpurposive samplin with a total of 30 students in the experimental class and 30 students in the control class. The research instrument was in the form of multiple choice questions with a total of 20 questions onpretest andposttest. The results of the experimental class research showed that the average value of student and teacher implementation was 96.9% in the very good category. As for the control class, the average student and teacher implementation score was 100% in the very good category. The results of the analysis show that the average N-Gain value in the experimental class is 0.63 and 0.4 in the control class in the moderate category. Student responses to learning using the NHT model assisted by Kokami media with an average of 77.5% in the sufficient category. The results of the t test analysis obtained the value of tcount7,475 > ttable1.671 at a significance level of 0.05, it can be concluded that the learning modelNumbered Head Together (NHT) assisted by Kokami media has a positive effect on students' critical thinking skills in excretory system material.
