Abstract

Student worksheets on colligative properties of electrolyte solutions science process skills-based have been developed by using RD method. Developed student worksheets have been validated with the result of it in high criteria. The limited testing was done to find out teachers responses about develop stuents worksheet. Based on teachers responses the suitability of content, construction, readability, and attractiveness aspect of it has very high category. Based on students responses,the readability and attractiveness aspect of it has very high category.Lembar kerja siswa sifat koligatif larutan elektrolit berbasis keterampilan proses sains telah dikembangkan menggunakan metode RD. Pengembangan lembar kerja siswa telah divalidasi dengan kriteria sangat tinggi. Pada uji coba lapangan awal telah dilakukan untuk mengetahui tanggapan guru dan siswa terhadap pengembangan lembar kerja siswa. Berdasarkan tanggapan guru terhadap aspek kesesuaian isi, konstruksi, keterbacaan dan kemenarikan memiliki kategori sangat tinggi. Berdasarkan tanggapan siswa pada aspek keterbacaan dan kemenarikan juga memiliki kategori yang sangat tinggi.Kata kunci: keterampilan proses sains, lembar kerja siswa , sifat koligatif larutan elektrolit

Abstract

This research which aimed to describe the validity, teachers and students responses, and feasibility of student worksheets of vapor pressure depression and boiling point elevation of solution has been implemented by using RD method. Developed student worksheets were declared valid by the judgement in content suitability, construction, and legibility aspect 97.22%, 100%, and 100%, respectively, with very high criteria. On preliminary field testing, the result was obtained by teachers and students responses which value of them were 95.47% dan 95.81%, respectively with very high criteria. Based on feasibility test, developed student worksheets worthy were declared by observer 83.36% and students responses in four which each of then were aspect 91.67%, 75.55%, 100%, and 83.33%, respectively, with high and very high criteria.Penelitian ini yang bertujuan untuk mendeskripsikan tingkat validitas, tanggapan guru dan siswa, serta uji keterlaksanaan LKS pada materi penuruan tekanan uap dan kenaikan titik didih larutan telah dilaksanakan dengan metode penelitian dan pengembangan (Research and Development). LKS dinyatakan valid oleh validator pada aspek kesesuaian isi, konstruksi, dan keterbacaan berturut-turut 97,22%, 100%, dan 100% dengan kriteria sangat tinggi. Pada uji coba secara terbatas diperoleh hasil dari responden guru dan siswa berturut-turut 95,47% dan 95,81% dengan kriteria sangat tinggi. Berdasarkan hasil uji keterlaksanaan, LKS dinyatakan layak digunakan dalam pembelajaran oleh observer sebesar 83,36% dan responden siswa dalam empat aspek berturut-turut 91,67%, 75,55%, 100%, dan 83,33% dengan kriteria sangat tinggi dan tinggi.Kata kunci: discovery learning, kenaikan titik didih larutan, LKS, penurunan tekanan uap

Abstract

The study which used research and development method has been to develop the colligative properties of electrolyte solution student worksheets based on science process skills. The goal of this research not only it, but also to describe its characteristic and teacher-student responses about the developed students worksheets. The results of expert validation about developed student worksheets were dedared valid with very high category. Teachers responses to suitability of content, construction, readability, and attractiveness aspect of developed student worksheet were categorized in very high. Student also gave responses in very high category to readability and attractiveness aspect of developed student worksheets.Telah dilaksanakan Penelitian menggunakan metode RD untuk mengembangkan LKS sifat koligatif larutan non-elektrolit LKS berdasarkan KPS.
