Tujuan penelitian ini adalah untuk memperoleh informasi perubahan kemampuan penalaran dan argumentasi ilmiah siswa setelah diterapkan model levels of inquiry berbasis Sosio-Scientific Issue pada pembelajaran IPA Materi Pemanasan Global. Tahapan Levels of Inquiry yang digunakan pada penelitian ini meliputi tiga tahap yaitu, Discovery Learning, Interactive Demonstration, dan Inquiry Lesson. Pada setiap tahapan Levels of Inquiry memiliki lima sintaks pembelajaran yaitu observation, manipulation, generalization, verification dan generalization. Metode yang digunakan adalah weak experiment dengan desain One Group Pre-test and Post-test. Subjek penelitian ini adalah siswa kelas 7 di salah satu SMP di kota Cimahi sejumlah 34 siswa. Berdasarkan analisis data, kemampuan penalaran ilmiah siswa memperoleh nilai N-gain sebesar 0,43 dengan kategori N-gain sedang. Persentase jumlah siswa berdasarkan kategori N-gain yaitu rendah 26,5%, sedang 58,8%, dan tinggi 14,7%. Pencapaian jumlah siswa dengan N-gain tertinggi tiap aspek yaitu proportional reasoning pada kategori tinggi sebesar 50,0%, control of variable pada kategori rendah sebesar 70,6%, inductive reasoning pada kategori tinggi sebesar 47,1%, correlational reasoning pada kategori sedang sebesar 41,2%, dan hypothetical deductive reasoning pada kategori sedang sebesar 50,0%. Selanjutnya, untuk kemampuan argumentasi ilmiah siswa memperoleh nilai N-gain sebesar 0,39 dengan kategori gain sedang. Persentase jumlah siswa berdasarkan kategori N-gain yaitu rendah 29,4%, sedang 61,8% dan tinggi 8,8%. Pencapaian jumlah siswa dengan N-gain tertinggi tiap aspek yaitu klaim pada kategori tinggi sebesar 50,0%, data pada kategori rendah sebesar 47,1%, warrant pada kategori rendah sebesar 38,2%, dan backing pada kategori sedang sebesar 55,9%. Berdasarkan hasil tersebut, dapat disimpulkan bahwa penerapan model Levels of Inqury berbasis Socio-scientific Issue pada pembelajaran IPA Materi Pemanasan Global dapat meningkatkan kemampuan penalaran dan argumentasi ilmiah siswa. The purpose of this study was to obtain information on changes in students' scientific reasoning and argumentative abilities after applying the level of inquiry model based on Socio-Scientific Issues in Global Warming Materials. The Levels of Inquiry stages in this study include three stages, namely, Discovery Learning, Interactive Demonstration, and Inquiry Lesson. At each stage Levels of Inquiry has five learning syntax, namely observation, manipulation, generalization, verification and generalization. The method was a weak experiment with One Group Pre-test and Post-test design. The subjects of this study were grade 7 students in one of junior high school in Cimahi with a total of 34 students. Based on data analysis, the scientific reasoning ability of students obtained an N-gain value of 0.43 with a moderate N-gain category. The percentage of students based on the N-gain category are low 26.5%, moderate 58.8%, and high 14.7%. The achievement of the number of students with the highest N-gain in every aspect are proportional reasoning in the high category by 50.0%, control of variables in the low category by 70.6%, inductive reasoning in the high category by 47.1%, correlational reasoning in the medium category by 41.2%, and hypothetical deductive reasoning in the medium category by 50.0%. Furthermore for the scientific argumentative ability, students obtain an N-gain value of 0.39 with the medium gain category. The percentage of students based on the N-gain category are low 29.4%, medium 61.8% and high 8.8%. The achievement of the number of students with the highest N-gain in every aspect are claims in the high category by 50.0%, data in the low category by 47.1%, warrant in the low category by 38.2%, and backing in the medium category by 55.9 %. Based on these results, it can be concluded that the application of the Socio-scientific Issue-based Levels of Inqury model to the learning of Science on Global Warming Material can improve students' scientific reasoning and argumentative abilities.
