EFEKTIVITAS BAHAN AJAR E-BOOK BERBASIS SCIENTIFIC APPROACH PADA MATA PELAJARAN EKONOMI KELAS XI IPS SEMESTER 1

THE EFFECTIVENESS OF E-BOOK TEACHING MATERIALS BASED ON SCIENTIFIC APPROACH ON ECONOMICS SUBJECT OF 1ST SEMESTER OF XI IPS CLASS

Bahan ajar yang kurang relevan dengan kebutuhan peserta didik dapat mempengaruhi efektivitas belajar, sehingga perlu pengembangan bahan ajar sesuai perkembangan teknologi untuk mencapai tujuan pembelajaran. Penelitian ini bertujuan mendeskripsikan kelayakan bahan ajar e-book berbasis scientific approach, menganalisis efektivitas, dan kepraktisan respon peserta didik terhadap bahan ajar e-book. Jenis penelitian ini yaitu penelitian pengembangan (Research & Development) dengan model 4D dari Thiagarajan yang meliputi define, design, develop, dan disseminate. Instrumen validitas produk diperoleh dari ahli materi, ahli bahasa, dan ahli grafis. Penelitian memperlihatkan (1) kelayakan pengembangan e-book “sangat layak” berdasarkan hasil rata-rata penilaian dari validator sebesar 90,33% yaitu validitas materi sebesar 97%, validitas bahasa sebesar 83%, dan validitas grafis sebesar 91%. (2) efektivitas  bahan ajar e-book menunjukan rata-rata  respon belajar kelas eksperimen sebesar 93,71%  yang sebelumnya sebesar 90,33%, (3) bahan ajar e-book dinilai praktis karena mampu mempermudah peserta didik dan mendukung KBM berdasarkan hasil penelitian respon peserta didik sebesar 93,53% dengan kriteria “sangat praktis” dari sebelumnya 93,13%. Berdasarkan hasil persentase bahan ajar e-book berbasis scientific approach efektif dan dinyatakan “sangat layak”sebagai sumber belajar peserta didik.

Teaching materials are deficient relevant to requirement of students can effectiveness effect of learning, so it is necessary to develop teaching materials according technological developments to achieve learning objectives. Research purpose to analyze effectiveness of e-book teaching materials based on a scientific approach, describe the feasibility and analyze practicality of student responses to e-book teaching materials. Type of study is research and development with a 4D model from Thiagarajan which includes define, design, develop, and disseminate. Product validity instruments were obtained from material experts, linguists, and graphic experts. Research shows (1) feasiblity Development of e-books "very feasible" based on average results of assessment  validator 90.33%, namely material validity 97%, language validity 83%, and graphic validity 91%. (1) the effectiveness of e-book teaching materials shows average learning response of the experimental class of 93.71% which was previously 90.33%, (3) e-book teaching materials are considered practical because they are able to facilitate students and support KBM based on results of research student responses 93.13% with the criteria of "very practical" from the previous 93,53%. from results of the percentage e-book teaching materials based on an effective scientific approach and declared "very feasible" as a learning resource for students.
