PENGEMBANGAN E-LKPD MELALUI PENDEKATAN LINGKUNGAN MATERI STRUKTUR DAN FUNGSI JARINGAN TUMBUHAN UNTUK MELATIHKAN BERPIKIR KRITIS SISWA KELAS XI SMA

THE DEVELOPMENT OF ELECTRONIC WORKSHEETS WITH THE ENVIROMENTAL APPROACH IN STRUCTURE AND FUNCTION PLANT TISSUES MATERIAL TO TRAIN CRITICAL THINKING OF GRADE 2^nd HIGH SCHOOL STUDENTS

Lembar Kegiatan Siswa merupakan salah satu bahan ajar yang berguna untuk menunjang kegiatan pembelajaran berupa observasi, penelitian, dan eksperimen yang bertujuan untuk memecahkan masalah yang berkaitan dengan makhluk hidup dan lingkungan. Penelitian ini merupakan penelitian pengembangan dengan menggunakan metode ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Produk yang dikembangkan adalah Lembar Kegiatan Siswa elektronik. Tujuan dari penelitian ini adalah mengembangkan bahan ajar LKPD elektronik, mendeskripsikan keabsahan LKS elektronik, dan menguji kepraktisannya dengan menggunakan angket respon siswa dan guru. Validitas LKPD elektronik ditinjau dari hasil validasi yang dinilai oleh dosen ahli materi dan ahli pendidikan. Kepraktisan dilihat dari respon guru sebagai praktisi dan 11 siswa kelas 2 SMA Al Azhar Menganti Gresik. Teknik analisis data dilakukan dengan menggunakan metode deskripsi kuantitatif. Hasil penelitian menunjukkan LKPD elektronik dinyatakan valid dengan persentase skor 96,6% dalam kategori sangat valid. LKS elektronik juga dinyatakan sangat praktis mengingat respon guru 100% dan siswa 98,5%. Dengan demikian LKPD elektronik pendekatan lingkungan materi struktur dan fungsi jaringan tumbuhan untuk melatih berpikir kritis siswa dinyatakan valid dan praktis untuk kegiatan belajar mengajar.
