Tetapi menumbuhkan sikap ilmiah siswa sebagai salah satu tujuan dari pembelajaranimasih kurang mendapat perhatian. Penelitian ini bertujuaniuntuk mengembangkan instrumenipenilaian sikap ilmiah pada pembelajaran fisika untuk memetakan minat belajar siswa yang valid, reliabel, dan praktis untuk digunakan. Jenis penelitian ini adalah penelitianipengembangan dengan menggunakan 7 langkah, yakni: penelitianidanipengumpulan data, perencanaan, pengembangan produk awal, ujiicoba lapangan awal, revisi hasil uji coba, uji coba lapangan, dan revisi produk operasional. Berdasarkan hasil validasi ahli, instrumen yangddikembangkan diperoleh nilai rata-rata persentase sebesar 80% denganikategoriisangat tinggi sehingga, instrumen penilaian ini layak untuk digunakan. Instrumen penilaian iniidiujicobakan kepada 100 siswa dan selanjutnyaidianalisis denganiexploratory factor analysis berbantuan program SPSS 21 for windows. Berdasarkan hasil analisis data uji coba diperoleh sebanyak 57 butir pernyataan instrumen sikap ilmiah untuk memetakan minat belajar siswa yangidinyatakan valid. Butir pernyataan pada instrumenipenilaian sikap ilmiah untuk memetakan minat belajar siswa dinyatakan reliabel dengan nilai Alpha Cronbachisebesar 0,952 pada instrumen sikap ilmiah, dan 0,927 pada instrumen minat belajar siswa dengan kategori sangat reliabel. Uji kepraktisan instrumenipenilaian ini memperoleh rata-rata skor sebesar 90,52% denganikriteria sangatipraktis.AbstractThe main use of attitude assessment as part of learning is a reflection of the understanding and progress of individual learner attitudes. However, cultivating students' scientific attitude as one of the goals of learning still receivesiless attention. This study aims toddeveloppscientific attitudedassessment instruments in physics learning to map student learning interests that are valid, reliable, and practical to use. This type of research is research-development using 7 steps, namely: research and dataicollection, planning, initialiproduct development, initial field trials, revision of trial results, field trials, and revision of operational products. Based on the results of expert validation, the instrument developed obtained an average percentageuvalue of 80% with a very highicategory so that this assessment instrument is feasible to use. Thisbassessment instrument was tested on 100 students and then analyzed using exploratory factor analysis with the help of the SPSS 21 for windows program. Based on the results of the trial data analysis, it was obtained as many as 57 scientific attitude instrument statements to map students' learning interests which were declared valid. The statement items on the instrument for assessing scientific attitudes to map students' interest in learning were declared reliable with a Cronbach's Alpha value of 0.952 in the scientific attitude instrument, and 0.927 in the instrument of student lear bning interest in the very reliable category. The practicality test of this assessment instrument obtained an average score of 90.52% with very practical criteria. Based on the results obtained, to increase students' interest in learning, it can be suggested to cultivate the scientific attitude of these students. With the growth of a good scientific attitude, the students' interest in learning will also be higher]]>
