This research used research and development model, namely 3D Development .The steps of 3D development were Define, Design, and Develop. Validation was carried out by 2 expert judgments and 2 practitioners to assess products developed from aspects of presentation, content, and language. Based on the results of the validity of the presentation aspects, the percentage results were 78.12% with very good categories, content aspects 81.85% with very good categories, language aspects at 82.75% and media aspects at 75% with very good categories. Based on these results, it can be concluded that the electronic teaching materials using Flip PDF Professional developed were valid and tested product with total validity test 79.4%, which is included in the excellent category.Keywords :Research and Development, Electronic Teaching Materials, Flip PDF Professional

This paper aimed at discovering the effect of critical thinking skills after the Ethno science-based Direct Instruction learning model was implemented in physics learning. It was conducted in High School 3 of Bengkulu City. This paper used the Quasi Experiment. The sample was gained using sampling purposive technique that was XI Natural Science 2 as experiment class and XI Natural Science 4 as control class. The results obtained indicated that the post-test average score of critical thinking skills acquired in the class using the Ethno science-based Direct Instruction learning model and the class using a conventional learning model. Based on the data analysis result using a t-test, it showed that the Ethno science-based Direct Instruction learning model influenced the students' critical thinking skills. The post-test average score of experiment class using the Ethno science-based Direct Instruction learning model and the post-test score of control class using the conventional model showed that there was a significant difference. Based on the hypothesis test, it was found that the alternative hypothesis (Ha) could significantly be accepted. This paper concluded that the students' critical skill raised effectively when using Ethno science-based Direct Instructional Learning Model especially for Physics Learning and the paper suggests not to use conventional model.

ABSTRAK Penelitian ini bertujuan untuk mengetahui karakteristik dan kelayakan modul yang dikembangkan  berbasis HOTS berbantuan Flipbook Marker sebagai bahan ajar alternatif siswa sekolah menengah atas.. Penelitian ini dilakukan dengan desain 4-D yang memiliki empat tahap yaitu tahap Define (Pendefinisian), Design (Perancangan), Develop (Pengembangan, dan Desseminate (Penyebaran), namun pada penelitian ini hanya dilaksanakan sampai tahap Develop. Instrumen penilaian yang digunakan dalam penelitian ini adalah lembar validasi ahli yang berisi aspek materi, aspek bahasa dan aspek media. Berdasarkan hasil uji validasi produk oleh ahli diperoleh presentase skor 84,7% untuk aspek materi, 81,0% untuk aspek bahasa, dan 81,2% untuk aspek media, sehingga total rata-rata skor adalah 82,3% termasuk ke dalam kategori sangat valid. Dengan demikian modul elektronik (e-modul) berbasis HOTS berbantuan Flipbook Marker menjadi produk jadi yang layak digunakan. Kata kunci: e-modul, HOTS, Flipbook Marker ABSTRACT This research aimed to determine the characteristics and the feasibility of the module developed based on HOTS aided by Flipbook Marker as an alternative teaching material for high school students.This research was carried out with a 4-D design that had four stages, namely the Define, Design, Develop and Desseminate stages, but in this study it was only carried out until the Develop stage. This is an expert validation sheet that contains material aspects, language aspects and media aspects Based on the results of the product validation test by the expert, a percentage score of 84.7% for the material aspect, 81.0% for the language aspect, and 81.2% for the media aspect , so that the total average score is 82.3% included in the very valid category, so the electronic module (e-module) based on HOTS aided by Flipbook Marker becomes a finished product that is suitable for use. Keywords: e-module, HOTS, Flipbook Marker

ABSTRAK Penelitian ini bertujuan untuk (1) menghasilkan media pembelajaran berbasis multimedia interaktif menggunakan Macromedia Director pada materi usaha dan energi kelas X, (2) mendeskripsikan kelayakan pengembangan media pembelajaran berbasis multimedia interaktif menggunakan Macromedia Director pada materi usaha dan energi kelas X. Jenis penelitian ini adalah Research and Development (R&D) level 1 yang dilaksanakan dalam lima tahap yaitu potensi dan masalah, studi literatur dan pengumpulan informasi, desain produk, validasi desain, dan desain teruji. Validasi desain menggunakan angket dan dilakukan oleh ahli. Hasil penelitian menunjukkan bahwa telah dihasilkan media pembelajaran berbasis multimedia interaktif yang berada dalam katergori sangat valid yaitu didapatkan penilaian pada aspek materi dengan presentase 89,58% dinyatakan pada tingkat yang valid, kemudian pada aspek media dengan presentase 84,37% dinyatakan pada tingkat yang valid, dan aspek bahasa dengan presentase 93,33% dinyatakan pada tingkat yang valid. Sehingga didapat bahwa media pembelajaran berbasis multimedia interaktif menggunakan Macromedia Director pada materi usaha dan energi kelas X dikategorikan valid dengan nilai rata-rata 89%.Kata Kunci: Macromedia Director, Multimedia Interaktif, Penelitian Pengembangan ABSTRACT This research was aimed to (1) produce learning media based on interactive multimedia that using macromedia Director on business and energy material at the grade X, (2) describe properness of developing interactive based multimedia learning that using macromedia director in effort and energy material of tenth grade.
