Abstract
Kemampuan berpikir kritis menjadi salah satu kemampuan yang harus dikuasai peserta didik. Namun, pada kondisi faktual didapati bahwa kemampuan berpikir kritis peserta didik masih rendah. Untuk mengatasi permasalahan tersebut peneliti menerapkan LKPD berbasis STEM pada materi transformasi energi. Adapun tujuan dari penelitian ini yaitu untuk mengetahui efektivitas LKPD berbasis STEM terhadap kemampuan berpikir kritis peserta didik kelas IV Sekolah Dasar. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi eksperimen dengan desain penelitian Non-equivalent Control Group Design. Pengambilan sampel menggunakan teknik purposive sampling. Sampel yang digunakan dalam penelitian ini yaitu peserta didik kelas IV A (kontrol) sebanyak 20 peserta didik dan kelas IV B (eksperimen) sebanyak 40 peserta didik di SDN Margahayu 02 Kabupaten Bandung. Instrumen yang digunakan yaitu berupa tes dalam bentuk soal uraian. Teknik analisis data yang digunakan yaitu uji prasyarat, uji hipotesis dan uji N-Gain. Taraf signifikansi yang digunakan yaitu 5% (0,05). Hasil uji N-Gain yang menunjukkan selisih 20% lebih besar pada kelas eksperimen. Pada kelas eksperimen hasil uji N-Gain menunjukkan kategorisasi sedang (0,40), dan pada kelas kontrol menunjukkan kategorisasi rendah (0,20). Pada Uji hipotesis diperoleh nilai sig. (2-tailed) sebesar 0,00 dengan kesimpulan H_1 diterima, terdapat perbedaan yang signifikan antara kemampuan berpikir kritis peserta didik kelas eksperimen dengan kelas kontrol. Oleh sebab itu maka dapat disimpulkan penerapan LKPD berbasis STEM lebih efektif digunakan dibandingkan dengan LKPD berbasis Saintifik. Rekomendasi bagi peneliti selanjutnya yaitu menggunakan instrumen selain instrumen tes, jumlah sampel disamakan antara kelas eksperimen dan kontrol, serta perlakuan diimplementasikan lebih dari 2 kali pertemuan. Critical thinking ability is one of the abilities that students must master. However, in factual conditions it was found that students' critical thinking abilities were still low. To overcome this problem, researchers applied STEM-based LKPD on energy transformation material. The aim of this research is to determine the effectiveness of STEM-based LKPD on the critical thinking abilities of fourth grade elementary school students. This research uses a quantitative approach with a quasi-experimental method with a Non-equivalent Control Group Design research design. Sampling used purposive sampling technique. The samples used in this research were 20 students in class IV A (control) and 40 students in class IV B (experiment) at SDN Margahayu 02, Bandung Regency. The instrument used is a test in the form of essay questions. The data analysis techniques used are prerequisite tests, hypothesis tests and N-Gain tests. The level of significance used is 5% (0.05). The N-Gain test results show a 20% greater difference in the experimental class. In the experimental class the results of the N-Gain test showed medium categorization (0.40), and in the control class it showed low categorization (0.20). In the hypothesis test, a sig value is obtained. (2-tailed) of 0.00 with the conclusion H_1 being accepted, there is a significant difference between the critical thinking abilities of experimental class students and the control class. Therefore, it can be concluded that the application of STEM-based LKPD is more effective compared to Scientific-based LKPD. Recommendations for future researchers are to use instruments other than test instruments, the number of samples is equalized between the experimental and control classes, and the treatment is implemented in more than 2 meetings.
