PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK-ELEKTRONIK (E-LKPD) LUMUT BERBASIS PENDEKATAN SAINTIFIK UNTUK MELATIH KEMAMPUAN BERPIKIR KRITIS SISWA

Development of Scientific Approach Based Electronical Student Worksheet (E-LKPD) Moss to Training Students' Critical Thinking Skills

Abstrak

Berpikir kritis termasuk tuntutan keterampilan yang perlu dikuasai siswa pada abad ke-21. Pendekatan saintifik dapat diterapkan dalam pembelajaran untuk melatih kemampuan berpikir kritis siswa.  Upaya untuk melatihkan kemampuan berpikir kritis dapat dilakukan menggunakan bahan ajar sesuai dengan abad ke-21 yaitu berbasis elektronik. Penelitian ini bertujuan menghasilkan E-LKPD Lumut untuk melatih kemampuan berpikir kritis siswa berdasarkan aspek validitas, kepraktisan dan keefektifan. Penelitian ini menggunakan model pengembangan 4D (Define, Design, Develop, dan Disseminate). Produk E-LKPD yang dihasilkan telah melalui proses telaah, revisi dan uji coba. Validitas E-LKPD diperoleh menggunakan instrumen validasi dengan memperhatikan aspek penyajian, isi, dan kebahasaan. Kepraktisan E-LKPD diperoleh menggunakan instrumen observasi keterlaksanaan. Keefektifan E-LKPD diperoleh menggunakan nilai tes berpikir kritis untuk menunjukkan persentase jumlah siswa yang memperoleh kriteria baik hingga sangat baik, dan respons positif siswa. E-LKPD dikategorikan valid apabila skor validasi ≥2,51, praktis apabila persentase keterlaksanaan ≥51%, dan efektif apabila persentase jumlah siswa kriteria baik hingga sangat baik pada tes berpikir kritis ≥70% dan respons positif siswa ≥75%. Data dianalisis secara deskriptif kuantitatif. Hasil uji validasi E-LKPD sebesar 3,88 (sangat valid). Hasil uji kepraktisan E-LKPD topik 1 dan topik 2 secara berturut-turut sebesar 99,05% dan 100% (sangat praktis). E-LKPD Lumut dinyatakan efektif dengan persentase jumlah siswa memperoleh kriteria baik hingga sangat baik pada tes berpikir kritis indikator interpretasi, analisis, dan eskplanasi secara berturut-turur sebesar 80%, 73,33%, dan 86,67% dan persentase respons positif siswa sebesar 95,10% (sangat baik). E-LKPD Lumut dinyatakan layak digunakan berdasarkan aspek validitas, kepraktisan, dan keefektifan untuk pembelajaran Biologi kelas X SMA.

Abstract

Critical thinking is one of the most in-demand talents for students in the 21st century. The scientific approach is a method of training students' critical thinking skills. Efforts to develop critical thinking abilities can be accomplished by using 21st-century educational resources, notably electronic-based materials. This research led to the development of E-LKPD moss, which will be used to teach students critical thinking skills based on feasibility, practicability, and effectiveness. The 4D development methodology (Define, Design, Develop, and Disseminate) is used in this research. The resulting E-LKPD product has gone through a process of review, revision and trial. The viability E-LKPD's was determined utilizing a validation sheet instrument that took into account presentation, content, and language. The practicality of the E-LKPD was obtained using the implementation observation instrument. E-LKPD's Critical thinking test scores were used to determine the effectiveness of the E-LKPD, which showed the percentage of students who met the criteria from good to very good and students' positive responses. E-LKPD is considered valid if the validation score is ≥2.51, practical if the proportion of implementation is ≥51%, and effective if the percentage of students who scored good to very good on the critical thinking test is ≥70%, and positive student responses are ≥75%. The data was quantitatively examined in a descriptive manner. The E-LKPD validation test vielded a score of 3.88 (very valid). The results of the E-LKPD topic 1 and topic 2 practicality tests are 99.05% and 100%, respectively (very practical). The E-LKPD moss program was shown to be effective, with 80%, 73.33%, and 86.67% of students scoring good to very good on the critical thinking test markers of interpretation, analysis, and explanation. The percentage of students who gave positive responses was 95.10%, (very good). E-LKPD moss was found to be suitable for use in Biology class X Senior High School based on its validity, practicality, and efficacy.
