<p class="E-JOURNALAbstractBody">Penelitian ini bertujuan untuk mendeskripsikan perbandingan kualitas Buku Sekolah Elektronik (BSE) dengan non-BSE mata pelajaran sains untuk sekolah dasar. Subjek dalam penelitian ini adalah empat buah BSE sains SD, dan empat buah buku sains SD non-BSE. Instrumen dikembangkan dengan merujuk pada <em>Science Textbook Rating System </em>yang dibuat oleh Collette & Chiapetta, dan grafik keterbacaan <em>Fry</em>. Analisis data yang dilakukan dalam penelitian ini menggunakan fasilitas program <em>SPSS 17.0 for Windows, </em>untuk menguji apakah terdapat perbedaan kualitas antara buku sains BSE dan non-BSE untuk sekolah dasar. Hasil penelitian menunjukkan hasil uji-t sebesar 0,564 dengan <em>t-tabel</em> sebesar 2,00 pada taraf signifikansi 5%. Berdasarkan nilai tersebut, disimpulkan bahwa hipotesis awal dapat diterima. Hasil dari penelitian ini menyimpulkan bahwa tidak ada perbedaan kualitas antara buku sains BSE dan non-BSE untuk sekolah dasar.</p> <p class="E-JOURNALAbstrakKeywords"><strong>Kata Kunci</strong>: kualitas, BSE, non-BSE, buku teks</p> <p class="E-JOURNALTitleEnglish"> </p> <p class="E-JOURNALTitleEnglish"><strong>AN ANALYSIS OF THE QUALITY OF BSE AND NON-BSE SCIENCE TEXTBOOKS FOR ELEMENTARY SCHOOLS WITH SCIENCE TEXTBOOKS ASSESSMENT SYSTEM</strong></p> <p><em><strong> </strong></em></p> <p class="E-JOURNALAbstrakTitle"><em><strong>Abstract</strong></em></p> <p class="E-JOURNALAbstractBodyEnglish">This study aims to describe the comparison of the quality of Buku Sekolah Elektronik (BSE) with non-BSE science textbooks for elementary schools. The subjects of this study were four BSE science textbooks for elementary schools, and and four non-BSE science textbooks for elementary schools. The instruments used in this study consisted of a questionnaire compiled by the researcher with reference to the Science Textbook Rating System made by Collette & Chiapettas, and Fry’s readability graph. The data were analysed using SPSS 17.0 for Windows, to know if there is any difference of quality between BSE and non-BSE science textbooks for elementary schools. The Technique of independent samples t-test shows the value of the T-test is 0.564 with t-table being 2.00 and the significance level of 5%. Based on that value, it can be concluded that the hypothesis is accepted. Therefore this study concludes that there is no difference in quality between the BSE and non-BSE science textbooks for elementary schools.</p> <strong>Keywords</strong>: quality, BSE, non-BSE, textbooks
