This type of research is quasi-experimental research that aims to 1) Determine the influence of problem-based learning (PBL) and Double Loop Problem Solving (DLPS) learning models on improving students' problem-solving ability. 2) Knowing the difference in the problem-solving ability of students with high creative and low creative thinking abilities. 3) Knowing the interaction of PBL and DLPS models with the ability to think creatively about problem solving. The population used in this study was grade VII students of state junior high schools in Lamongan Regency for the 2021/2022 academic year. The samples in this study consisted of 4 classes. The experimental class uses 1 PBL model for as many as two classes, and the experimental class 2 DLPS models for as many as two classes. Data collection using problem-solving ability test instruments and creative thinking test instruments. Hypothesis testing of the study using a two-way anava test with the study's results 1) There was no influence of the PBL and DLPS learning models on improving students' problem-solving ability. 2) there are differences in the problem-solving ability of students with high and low creative thinking abilities. 3) there is no interaction of the PBL and DLPS models with the ability to think creatively about students' problem-solving abilities.

<p>Penelitian ini membahas berbagai literatur tentang model <em>Double Loop Problem Solving</em> (DLPS) sebagai solusi ketika mengembangkan kemampuan siswa SMP dalam memecahkan permasalahan. Instrumen dalam penelitian ini menggunakan tes wawancara untuk guru dan siswa kelas VII SMPN 3 Singosari. Berdasarkan wawancara memperlihatkan kemampuan siswa tergolong rendah ketika memecahan masalah. Terlihat dari prilaku siswa yang pasif ketika proses pembelajaran berlangsung. Kebanyakan siswa berasumsi materi IPA adalah materi yang sulit dipahami, dan membosankan. Hal tersebut terjadi karena siswa ketika proses pembelajaran berlangsung hanya mendengarkan saat guru menjelaskan dan tidak terlibat langsung dalam mengkaji materi yang dipelajari. Guru dalam proses pembelajaran telah menyesuaikan kurikulum 2013 dengan menerapkan model pembelajaran <em>discovery learning</em>, tetapi pada prosesnya guru hanya berceramah ketika menjelaskan materi. Metode yang digunakan adalah studi literatur dan wawancara. Berdasarkan hasil studi literatur dibutuhkan solusi untuk mengatasi masalah tersebut adalah dengan penerapan model pembelajaran<em> Double Loop Problem Solving</em>.</p>
