Abstract

Berdasarkan hasil penelitian PISA diketahui bahwa kemampuan berpikir kritis siswa di Indonesia tergolong rendah berdasarkan soal ujian PISA terdiri dari level 1-6 dan siswa mampu menjawab soal sampai pada level 2. hasil ini menunjukan kemampuan berpikir masih sangat rendah. Penelitian ini bertujuan untuk: (1) mengetahui perbedaan kemampuan berpikir kritis siswa menggunakan model CORE dengan model discovery learning (2) mengetahui apakah kemampuan berpikir kritis siswa yang diajarkan dengan penerapan model pembelajaran CORE lebih tinggi dari pada yang diajarkan dengan model discovery learning. Desain penelitian eksperimen dengan pretest-postest control group design. Populasi penelitian seluruh siswa kelas XI IPA SMAN 71. Sampel penelitian terdiri dari dua kelas dengan jumlah sampel 62 siswa dengan purposive sampling, yaitu kelas XI IPA 1 sebagai kelas ekperimen 1 menggunakan model CORE sebanyak 31 siswa dan kelas XI IPA 2 sebagai kelas eksperimen 2 menggunakan model pembelajaran discovery learning sebanyak 31 siswa. Instrumen penelitian yang digunakan adalah esai sebanyak 7 soal. Uji persayaratan analisis menunjukkan data terdistribusi normal dan homogen. Sehingga uji hipotesis statistik yang digunakan uji parametrik. Uji hipotesis dengan one way anova dan uji paired samples t test. Hasil analisis menunjukkan bahwa (1) terdapat perbedaan hasil belajar kimia siswa melalui model CORE tidak sama dengan model discovery learning dengan hasil analisa F hitung < F tabel (0,949 > 2,12) sehingga dapat dinyatakan μ1 ≠ μ2. (2) hasil belajar kimia siswa dengan model CORE lebih tinggi dari pada model discovery learning dengan hasil analisa t hitung > t tabel (9,769 > 2,00) sehingga dapat dinyatakan μ1 > μ2. Kata kunci : berpikir kritis, CORE, discovery learning, hidrokarbon. Research conducted based on PISA said that students' critical thinking skills in Indonesia were classified as low based on PISA exam questions consisting of levels 1-6 and students were able to answer questions at levels 1-2. these results indicate that the ability to think is still very low. This study aims to: (1) find out the difference in students 'critical thinking skills using the CORE model with the discovery learning model (2) determine whether the students' critical thinking skills taught by applying the CORE learning model are higher than those taught with the discovery learning model. Experimental research design with pretest-posttest control group design. The study population was all students of Class XI Science Natural High School 71. The research sample consisted of two classes with a total sample of 62 students with purposive sampling, namely Class XI Science 1 as an experimental class 1 using a CORE model of 31 students and Class XI Science 2 as an experimental class 2 using discovery learning learning model of 31 students. The research instrument used was 7 essays. The analysis requirements test shows that the data are normally distributed and homogeneous. So the statistical hypothesis test used parametric tests. Hypothesis testing with one way ANOVA and paired samples t test. The results of the analysis show that (1) there are differences in student chemistry learning outcomes through the CORE model not the same as the discovery learning model with the analysis results F count <F table (0.949> 2.12) so that it can be stated μ1 ≠ μ2. (2) students' chemistry learning outcomes with the CORE model are higher than the discovery learning model with the results of t analysis> t table (9,769> 2.00) so that it can be stated μ1> μ2.
