Abstract

This research was aimed to describe the validity, practicality and effectiveness of discovery learning student worksheets on quantum mechanic atomic theory. This research used Research and Development method that consist of: preliminary study, designing student worksheets, expert testing, and preliminary field testing. Preliminary field testing was conducted in 10th grade of MIA5 at SMA Belitang to observe practicality and effectiveness of student worksheets. The validaton result showed that student worksheet has very high validity. The teachers responses on aspect of content, readability, construction, atractiveness and students responses on aspect of readability, atractiveness showed that student worksheets has good practicality. The implementation of student worksheets has very high category and student achievement showed that student worksheet was effective.Penelitian ini bertujuan untuk mendeskripsikan validitas, kepraktisan dan keefektivan Lembar Kerja Siswa dengan model discovery learning pada materi teori atom mekanika kuantum. Penelitian ini menggunakan metode penelitian dan pengembangan yang terdiri dari: studi pendahuluan, desain LKS, uji ahli serta uji coba terbatas. Uji coba terbatas dilakukan pada kelas X MIA5SMA Negeri 1 Belitang untuk melihat kepraktisan dan keefektivan dari LKS yang telah dibuat. Hasil validasi ahli menunjukkan bahwa LKS memiliki validitas yang sangat tinggi. Respon guru terhadap aspek kesesuaian isi, keterbacaan, konstruksi, kemenarikan dan respon siswa pada aspek keterbacaan dan kemenarikan menunjukkan bahwa LKS mempunyai kepraktisan yang baik. Keterlaksanaan LKS mempunyai kategori sangat tinggi dan hasil belajar siswa menunjukkan bahwa LKS efektif.Kata kunci : LKS, model discovery learning, teori atom mekanika kuantum

Abstract

This study was aimed to (1) develop student worksheets based on scientific approach on factors affecting reaction rate, (2) describe characteristic of the student worksheets that developed, (3) describe teacher response of the student worksheets that developed, and (4) describe students response of the student worksheets that developed. The Research and Development method by Sugiono (2013) was used in this study. Limited testing has done at one school in North Lampung. Based on the limited testing result for teacher and students response of the student worksheets that developed, the percentage of teacher response in suitability content, readability, and attractiveness were 94.54%; 93.33%; and 96.00%, respectively. The results of students responses to the readability and attractiveness were also very high, with the percentage until 84.87% and 86.90%, respectively.Penelitian ini bertujuan untuk (1) mengembangkan LKS berbasis pendekatan saintifik pada materi faktor-faktor yang mempengaruhi laju reaksi, (2) mendeskripsikan karakteristik LKS yang dikembangkan, (3) mendeskripsikan respon guru terhadap LKS yang dikembangkan, dan (4) mendeskripsikan respon siswa terhadap LKS yang dikembangkan. Penelitian ini menggunakan metode penelitian dan pengembangan menurut Sugiono (2013). Uji coba terbatas dilakukan pada salah satu sekolah di Kabupaten Lampung Utara. Berdasarkan hasil uji coba terbatas pada respon guru dan respon siswa terhadap LKS yang dikembangkan, persentase respon guru pada aspek kesesuaian isi, keterbacaan dan kemenarikan masing-masing adalah 94,54%; 93,33%; dan 96,00%. Hasil respon siswa pada aspek keterbacaan dan kemenarikan juga sangat tinggi, dengan persentase masing-masing mencapai 84,87% dan 86,90%.Kata kunci: faktor-faktor yang mempengaruhi laju reaksi, LKS, pendekatan saintifik
