PENGEMBANGAN LEMBAR KEGIATAN PESERTA DIDIK ELEKTRONIK (E-LKPD) BERBASIS PROBLEM BASED LEARNING PADA MATERI PERUBAHAN LINGKUNGAN UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS

The Development of an Electronic Worksheet Based on Problem Based Learning in Environmental Change Materials to Train Critical Thinking Ability

Persaingan global pada abad ke-21 dapat diatasi dengan menyiapkan kemampuan berpikir kritis. Seiring dengan perkembangan teknologi, berpikir kritis dapat dilatihkan dengan E-LKPD berbasis Problem Based Learning (PBL). Penelitian pengembangan ini memiliki tujuan untuk menghasilkan E-LKPD berbasis PBL pada materi perubahan lingkungan untuk melatihkan kemampuan berpikir kritis peserta didik yang layak berdasarkan validitas, kepraktisan, dan keefektifan. Penelitian ini menggunakan model 4-D (define, design, develop, dan disseminate), tanpa tahap disseminate. Tahap uji coba dilakukan pada 20 peserta didik di SMAN 1 Kenduruan kelas X-2. Parameter penelitian ini adalah hasil validitas, kepraktisan, dan keefektifan. Validitas diperoleh dari hasil validasi oleh ahli. Kepraktisan diperoleh dari lembar observasi. Keefektifan diperoleh dari hasil test berpikir kritis dan angket respons peserta didik. Data dianalisis dengan cara deskriptif kuantitatif. E-LKPD dinyatakan valid jika mendapatkan persentase ≥ 75%, praktis jika persentase aktivitas ≥ 75%, serta efektif jika ketercapaian indikator berpikir kritis dan respons peserta didik ≥ 75%.  Hasil penelitian diperoleh rata-rata keseluruhan aspek validasi 98,96% (sangat valid). Kepraktisan berdasarkan aktivitas peserta didik pada E-LKPD 1 diperoleh persentase 95,71% (sangat baik) dan pada E-LKPD 2 diperoleh persentase 97,5% (sangat baik). Keefektifan E-LKPD diperoleh ketercapaian indikator interpretasi 90% (sangat baik), analisis 79,5% (baik), dan inferensi 87,5% (baik), berdasarkan respons peserta didik diperoleh persentase 97% (sangat positif). Berdasarkan hasil penelitian dapat diketahui bahwa E-LKPD berbasis PBL layak digunakan berdasarkan kevalidan, kepraktisan, dan keefektifan.

Global competition in the 21st century can be overcome by developing critical thinking skills. Along with technological developments, critical thinking can be trained with E-LKPD based on Problem Based Learning (PBL). This development research aims to produce E-LKPD based PBL on environmental change material to train students' critical thinking skills that are appropriate based on validity, practicality, and effectiveness. This study uses a 4-D model (define, design, develop, and disseminate) without the disseminate stage. The trial phase was carried out on 20 students in the X-2 class of SMAN 1 Kenduruan. The parameters of this study are validity, practicality, and effectiveness. Validity is obtained from the results of validation by experts. Practicality is obtained from the observation sheet. Effectiveness is obtained from the results of critical thinking tests and student response questionnaires. The data were analyzed by means of descriptive and quantitative methods. E-LKPD is declared valid if it gets a percentage of ≥ 75%, practical if the percentage of activity is ≥ 75%, and effective if the achievement of critical thinking indicators and student responses is ≥ 75%. The research results obtained an overall average validation aspect of 98.96% (very valid). Practicality based on student activity in E-LKPD 1 obtained a percentage of 95.71% (very good) and in E-LKPD 2 a percentage of 97.5% (very good). The effectiveness of the E-LKPD was obtained by achieving 90% (very good) interpretation indicators, 79.5% (good) analysis, and 87.5% (good) inference based on the responses of students, which obtained a percentage of 97% (very positive). Based on the results of the study, it can be seen that E-LKPD based PBL is feasible to use based on validity, practicality, and effectiveness.
