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 ?1 ? ?2. (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 ?1 > ?2.

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 2.12) so that
it can be stated ?1 ? ?2. (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 ?1> ?2.
