Penelitian ini bertujuan untuk mengetahui kelayakan dan mengetahui respon siswa terhadap modul. penelitian ini menggunakan model borg & gall sampai pada tahap ketujuh. langkah-langkah pengembangannya adalah 1) penelitian dan pengumpulan informasi awal; 2) perencanaan; 3) pengembangan produk awal; 4) uji coba lapangan utama; 5) revisi produk utama; 6) uji coba lapangan; 7) revisi produk operasional. modul divalidasi oleh ahli materi, ahli media, dan ahli praktisi. uji coba produk dilakukan sebanyak dua kali yaitu uji coba lapangan awal yang melibatkan 12 siswa di kelas xi ipa dan uji coba lapangan utama yang melibatkan 37 siswa di kelas x-6. hasil validasi ahli materi sebesar 98,75% (sangat layak), ahli media sebesar 92,76% (sangat layak), dan ahli praktisi sebesar 97,68% (sangat layak). hasil angket respon siswa pada uji coba lapangan awal sebesar 83,51% (sangat setuju), uji coba palangan utama sebesar 83,40% (sangat setuju). sehingga dapat disimpulkan modul biologi berorientasi inkuiri tervalidasi layak.

The purpose of the research to measure the properness and students’ respon on developing biologi module oriented inquiry. the study was based on borg & gall model until the seventh step. the development steps were as follow 1) research and information and collection; 2) planning; 3) development premilimnary form of product; 4) preminilary field testing 5) main product revision; 6) main field testing; 7) operational product revision. the module was validated by material expert, media expert, and practioptioner expert. the field test was conducted twice, namely initial trial with 12 students at class xi-ipa and principal trial with 37 students at class x-6. the validation results from material expert was 98,75% (very appropriate), 92,76% (very appropriate) from layout dan design expert, and from practitioner expert was 97,68% (very appropriate). the result of evaluation questioner for students in initial trial was 83,51%(very agree), the result of evaluation questioner for students in msin field try out was 83,40% (very agree). the conclusion of this research biology module oriented inquiry has develop is validated as viable.
