DEVELOPMENT OF STUDENT WORKSHEET ORIENTED TO CONCEPT MAP ON CHEMICAL BONDING MATTER CLASS X

Abstract

Penelitian ini bertujuan untuk mengetahui kelayakan Lembar Kerja Siswa (LKS) dan hasil belajar siswa terhadap lembar kerja siswa berorientasi peta konsep pada materi pokok ikatan kimia kelas X-SMA. Jenis penelitian ini merupakan penelitian pengembangan dengan menggunakan model pengembangan Research and Development (R&D). Terdapat 10 langkah pengembangan yaitu potensi dan masalah, pengumpulan data, desain produk, validasi desain, revisi desain, ujicoba produk,  revisi produk, ujicoba pemakaian, revisi produk, dan produksi masal. Namun, penelitian ini hanya terbatas sampai enam langkah yaitu uji coba produk. Lembar kerja siswa ini ditelaah dan divalidasi oleh 2 dosen kimia Universitas Negeri Surabaya, 1 guru kimia SMAN Kesamben-Jombang. Subjek penelitian dalam uji coba kelayakan LKS adalah siswa kelas X-3 SMAN Kesamben  sebanyak 16 siswa. Hasil penelitian menunjukkan bahwa LKS sangat layak digunakan dengan total persentase kelayakan sebesar 87,20%. Dari penelitian, hasil belajar siswa meningkat hingga 81,25%.

 The aims of this study to know the feasibility of studentworksheet and learning outcomes to student worksheets oriented concept map of chemical bonding matter class X. The type of this research use“research and development” model or usually known as (R&D).There are 10 steps include potention and problem, collecting data, design of product, revision of product, revision of design, test of product, revision of product, test of product and production. But in this research just until test of product.The student worksheet was analyzed and validated by 2 chemistry lecturers of Surabaya State University and 1 chemistry teacher of SMAN Kesamben-Jombang. Subjects of this observation are 16 students of SMAN Kesamben class X-3. The results showed that student worksheet is very suitable to be used with a total percentage of 87,20% viability. The score of student increase from pretest to the postest until 81,25%.
