<![CDATA[This research was motivated by the low creative thinking skills of fifth-grade B students at SDN Sidokepung 1 in Science learning, specifically regarding the food chain material, as evidenced by students' passive attitude during conventional learning. This study aimed to examine the effect of the inquiry learning model on students' creative thinking skills. Employing a quantitative approach with a pre-experimental method and a One Group Pretest-Posttest Design, this study involved a saturated sample of 34 students. The data collection instrument consisted of 10 essay test items that had been tested for validity and reliability. Data were analyzed using the non-parametric Wilcoxon Signed Rank Test and N-Gain Score analysis. The results demonstrated an increase in the mean score from 42.79 in the pretest to 77.94 in the posttest. The Wilcoxon test yielded a significance value of 0.000 (< 0.05), indicating a significant difference in competence before and after the treatment. Furthermore, the average N-Gain score reached 0.60 (medium category), and the N-Gain percentage was 60.60% (moderately effective). The main finding of this study indicates that the implementation of the inquiry learning model significantly improved students’ creative thinking skills, with the level of improvement falling within the medium category and demonstrating moderate effectiveness. In conclusion, the inquiry learning model exerts a positive and significant influence on enhancing elementary school students' creative thinking skills through active and independent learning experiences. ABSTRAK Penelitian ini di latar belakangi oleh rendahnya keterampilan berpikir kreatif siswa kelas V B SDN Sidokepung 1 pada pembelajaran IPA materi rantai makanan, yang tercermin dari dominasi sikap pasif selama proses belajar konvensional.

Pendekatan kuantitatif melalui metode pre-experiment dengan rancangan One Group Pretest-Posttest Design diadopsi dalam studi ini, dengan melibatkan sampel jenuh yang terdiri atas 34 siswa. Data dikumpulkan menggunakan instrumen tes esai sebanyak 10 butir soal yang statusnya telah valid dan reliabel. Teknik analisis data yang diaplikasikan meliputi uji non-parametrik Wilcoxon Signed Rank Test serta analisis N-Gain Score. Temuan penelitian mengonfirmasi adanya kenaikan skor rata-rata dari 42,79 saat pretest menjadi 77,94 saat posttest. Selain itu, uji Wilcoxon menorehkan nilai signifikansi 0,000 (< 0,05), yang membuktikan adanya perbedaan kompetensi yang nyata sebelum dan sesudah intervensi. Capaian ini didukung oleh rata-rata N-Gain score senilai 0,60 (kategori sedang) dan N-Gain persen sebesar 60,60% (kriteria cukup efektif). Temuan utama penelitian menunjukkan bahwa penerapan model pembelajaran inquiry mampu meningkatkan keterampilan berpikir kreatif siswa secara signifikan, dengan tingkat peningkatan berada pada kategori sedang dan efektivitas cukup.
