Pembelajaran pada kurikulum 2013 menekankan peserta didik untuk lebih aktif dan memiliki kemampuan yang unggul seperti keterampilan berpikir kreatif. Tujuan penelitian ini yaitu mendeskripsikan kelayakan Lembar Kerja Peserta Didik (LKPD) dengan strategi mind mapping untuk meningkatkan keterampilan berpikir kreatif pada materi stoikiometri. Kelayakan lembar kerja peserta didik ditinjau dari 3 aspek yaitu isi, penyajian, dan kebahasaan. Penelitian ini mengacu pada model pengembangan 4-D yang telah dimodifikasi menjadi 3-D yaitu define,  design, dan develop. Pelaksaan uji coba terbatas dilakukan di SMA Negeri 3 Kota Mojokerto oleh 12 peserta didik kelas X MIPA 2. Hasil kelayakan lembar kerja peserta didik pada aspek isi, penyajian dan kebahasaan masing-masing sebesar 91,88%;93,55;86,67% dengan kategori sangat layak. Data yang diperoleh dari uji coba terbatas yaitu aktivitas dan respon peserta didik masing-masing memperoleh persentase sebesar 97,62% dan 88,02%. Peningkatan keterampilan berpikir kreatif dan hasil belajar peserta didik diperoleh dengan nilai N-Gain masing-masing sebesar 0,74 dan 0,75 termasuk kategori tinggi. Berdasarkan hasil tersebut dapat disimpulkan bahwa LKPD dengan strategi mind mapping layak dan dapat meningkatkan keterampilan berpikir kreatif serta hasil belajar peserta didik pada materi stoikiometri.

The learning process of 2013 curriculum emphasizes on the students’ skill, it also demands them to be more active and have extraordinary abilities such as creative thinking skills. The purpose of this study is to describe the feasibility of the Students’ Worksheet with the mind mapping strategy to improve the students’ creative thinking skills on stoichiometry material. There are tree aspects which were observed in the students’ worksheets to measure the feasibility, those are content, presentation, and language. This study was conducted based on 4-D development model which has been modified into 3-D (define, design, and develop). The limited trial was implemented on 12 students of X Science 2 in Senior High School 3 Mojokerto. Furthermore, the results showed that from the three aspects of students’ worksheet which were content, presentation and language were categorized to be very feasible with the percentage 91.88%;93.55%;86.67%. The students’ activities and responses were the data that obtained through the limited trials with the percentage 97.62% and 88.02% of each. Moreover, the increasing of the students’ creative thinking skills and learning outcomes can be seen from the N-Gain value which were 0.74 and 0.75, and belonged to high category. Based on the results it can be concluded that the students’ worksheet with a mind mapping strategy was feasible and able to improve the students’ creative thinking skills and learning outcomes on stoichiometry material
