PENGEMBANGAN E-LKPD BERBASIS PROBLEM SOLVING PADA MATERI PERTUMBUHAN DAN PERKEMBANGAN UNTUK MELATIH KETERAMPILAN BERPIKIR KRITIS SISWA KELAS XII SMA

The Development of Student Worksheet Based On Problem Solving in Plant Growth and Development Topic to Train Critical Thinking Skills for 12^th in Senior High School

Berpikir kritis merupakan kemampuan untuk menganalisis, bernalar secara sistematis serta memecahkan masalah. Keterampilan berpikir kritis dapat dilatihkan melalui Lembar Kerja Peserta Didik (LKPD). Oleh sebab itu, pengembangan E-LKPD berbasis problem solving sangat diperlukan guna memenuhi tuntutan pembelajaran abad 21 tentang kecakapan literasi digital pada siswa serta untuk melatih keterampilan berpikir kritis. Tujuan penelitian ini yaitu untuk menghasilkan E-LKPD berbasis problem solving pada materi pertumbuhan dan perkembangan untuk melatih keterampilan berpikir kritis siswa kelas XII SMA yang layak ditinjau dari validitas, kepraktisan, dan keefektivan. Penelitian ini merupakan jenis penelitian pengembangan dengan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation).   Data yang diperoleh berupa validitas tinjau berdasarkan aspek tampilan, isi serta bahasa oleh ahli media dan ahli materi, kepraktisan ditinjau berdasarkan aktivitas dan respon siswa terhadap penggunaan E-LKPD, sedangkan keefektivan ditinjau berdasarkan ketercapaian indikator berpikir kritis. Hasil penelitian menunjukkan E-LKPD layak untuk digunakan dengan persentase skor validitas mencapai 83,58% dengan kriteria sangat valid, kepraktisan memperoleh skor 93,94% termasuk kriteria sangat praktis, dan keefektivan memperoleh skor 90,93% dengan kriteria sangat baik. Dengan demikian, dapat disimpulkan bahwa E-LKPD berbasis problem solving pada materi pertumbuhan dan perkembangan untuk melatih keterampilan berpikir kritis dinyatakan sangat valid, sangat praktis, dan sangat efektiv.

Critical thinking is the ability to analyze, think systematically and solve problems. Critical thinking skills can be trained through Student Worksheets (LKPD). Therefore, the development of problem solving-based E-LKPD is needed to meet 21st-century learning demands relating to students' digital literacy skills and introduce critical thinking skills. The purpose of this study is to produce an E-LKPD based on problem-solving on growth and development materials to train critical thinking skills in XII high school students' classes in terms of validity, practicality, and effectiveness. This study is a type of development research with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Furthermore, the data obtained are in review validity based on appearance aspects, content and language by media experts and material experts. Practicality is reviewed based on student activities and responses to the use of E-LKPD. Meanwhile, effectiveness is reviewed based on the critical thinking indicators' achievement. The results indicated that the E-LKPD was practicable to use with the percentage of validity index of 83.58% with very valid criteria, practicality getting a value of 93.94% with efficient criteria, and effectiveness getting a value of 90.93% with excellent criteria. Thus, it can be concluded that problem solving-based E-LKPD on growth and development materials to practice critical thinking skills can be stated as very valid, very practical, and very effective.
