<![CDATA[AbstrakPenelitian bertujuan mengetahui kelayakan dan efektivitas buku ajar pembelajaran IPA SD untuk mahasiswa PGSD. Indikator kelayakan pakar Pembelajaran; isi, penyajian, dan kebahasaan. Indikator kelayakan pakar media; ukuran buku ajar, desain cover, dan desain isi. Indikator kelayakan dosen adalah kejelasan, kesesuaian dengan kurikulum, keutuhan penerimaan, pengaruh produk, ketepatan waktu dan kepraktisan. Tahapan penelitian RD; studi pendahuluan, perancangan produk, validasi pakar, implementasi produk dan sosialisasi. Alat pengumpul data; angket, soal tes, dan dokumentasi. Data kualitatif dianalisis dengan hitungan persentase. Data kuantitatif diujiprasyaratkan dan uji hipotesis. Hasil menunjukkan produk sangat baik (96,1), penilaian dari pengguna buku sangat baik (90,1). Hasil implementasi menunjukkan sebaran data normal dan tidak homogen. Sehingga uji hipotesis menggunakan uji non parametrik diperoleh nilai p-level (0.000) alpha artinya ada pengaruh penggunaan produk terhadap hasil belajar. Rata-rata hasil belajar sangat baik (95,31). Kesimpulannya bahwa buku ajar mata kuliah pembelajaran IPA di SD sudah layak dan efektif untuk diimplementasikan. AbstractThe aim of the study was to assess the feasibility of textbooks for science learning course in Primary schools for college students in the PGSD. Indicators of feasibility by science learning are content, presentation and language. Feasibility indicators by media experts are the size of textbooks, cover design and content design. Feasibility indicators for lecturer were clarity, suitability with the curriculum, integrity of acceptance, product influence, timeliness and practicality. The research stages of RD were preliminary studies, product design, experts validation, product implementation and product socialization. Instrument for data collection were questionnaires, test and documentation. Qualitative data was analyzed by percentage and quantitative data would be tested and hypothesis tested. The results of the study showed that the experts assessment of the product was in very good (96.1), the assessment of the lecturer and college students as users of the textbook was very good (90.1). the results of product implementation show normal and not homogeneous data distribution. So that the hypothesis test uses the non-parametric and obtained the p-level (0.000) alpha, this means that there is an influence of product use on learning outcomes. The average score of the learning outcomes was in very good (95.31). The conclusion is that the textbooks of science learning courses in primary schools are feasible to be implemented and used. ]]>
