Abstract

Penelitian ini bertujuan untuk mengevaluasi Efektivitas serta seberapa besar dampak media Pictorial Riddle dalam meningkatkan kemampuan berpikir kritis siswa dalam materi hukum dasar kimia pada kelas X. Pelaksanaan penelitian ini berlangsung di SMA Negeri 42 Jakarta di semester genap tahun akademik 2022/2023. Teknik pemilihan sampel menggunakan purposive sampling, sehingga subjek penelitian terdiri dari kelas X-5 sebagai kelompok eksperimen dengan jumlah siswa sebanyak 35 dan kelas X-2 sebagai kelompok kontrol dengan jumlah siswa yang sama. Desain penelitian yang diterapkan adalah Nonequivalent Control Group Design. Pengujian hipotesis dilakukan dengan memanfaatkan aplikasi SPSS versi 26 melalui metode Independent Sample T test dan Uji NGain. Hasil analisis Independent Sample T test terhadap efektivitas media pembelajaran Pictorial Riddle menghasilkan perbandingan antara ttabel (1,667) dengan thitung (4,593). Oleh karena ttabel < thitung (1,667 < 4,593), maka H0 yang menyatakan bahwa Media Pembelajaran Pictorial Riddle Tidak Efektif Meningkatkan Kemampuan Berpikir Kritis Siswa ditolak, dan Ha yang menyatakan bahwa Media Pembelajaran Pictorial Riddle Efektif Meningkatkan Kemampuan Berpikir Kritis Siswa diterima. Selanjutnya, hasil uji NGain menunjukkan bahwa rata-rata nilai NGain pada kelas eksperimen mencapai 71,53%, dengan kategori cukup efektif. Sedangkan di kelas kontrol, nilai rata-rata NGain mencapai 46,92%, dengan kategori kurang efektif. Dari hasil ini dapat disimpulkan bahwa media Pembelajaran Pictorial Riddle efektif dalam meningkatkan kemampuan berpikir kritis siswa. Kesimpulan dari penelitian ini adalah bahwa media Pembelajaran Pictorial Riddle terbukti efektif dalam meningkatkan kemampuan berpikir kritis siswa dalam konteks pembelajaran hukum dasar kimia pada kelas X. Kata kunci: Keterampilan 4C, Efektivitas, Media Pictorial Riddle, Kemampuan Berpikir Kritis. / This study aims to evaluate the effectiveness and how much impact Pictorial Riddle learning media has in improving students' critical thinking skills in basic chemical law material in class X. The implementation of this research took place at SMA Negeri 42 Jakarta in the even semester of the 2022/2023 academic year. The sample selection technique uses purposive sampling, so that the research subjects consist of class X-5 as an experimental group with 35 students and class X-2 as a control group with the same number of students. The research design applied is Nonequivalent Control Group Design. Hypothesis testing was carried out by utilizing the SPSS version 26 application through the Independent Sample T test and NGain Test methods. The results of the Independent Sample T test analysis of the effectiveness of Pictorial Riddle learning media resulted in a comparison between ttabel (1.667) and tcount (4.593). Because ttable < tcount (1.667 < 4.593), H0 which states that Pictorial Riddle Learning Media is Not Effective in Improving Students' Critical Thinking Skills is rejected, and Ha which states that Pictorial Riddle Learning Media is Effective in Improving Students' Critical Thinking Skills is accepted. Furthermore, the results of the NGain test showed that the average NGain value in the experimental class reached 71.53%, with the category quite effective. While in the control class, the average score of NGain reached 46.92%, with the category less effective. From these results, it can be concluded that Pictorial Riddle Learning media is effective in improving students' critical thinking skills. The conclusion of this study is that Pictorial Riddle Learning media is proven effective in improving students' critical thinking skills in the context of learning basic chemistry laws in class X. Keywords: 4C Skills, Effectiveness, Media Pictorial Riddle, Critical Thinking Ability
