Abstract

The teaching tools are crucial for teachers in delivering instructional material. However, the development of learning tools that meet content standards and are of high quality is still quite rare. This research aims to develop and evaluate the quality of Project-Based Outdoor Learning (PjBOL) tools for geometry to enhance problem-solving skills. The research sample consists of students from classes VII D and VII E at SMP Negeri 2 Ungaran. The research method used is Research and Development with the Four-D model: Define, Design, Develop, Disseminate. The research instruments include expert assessment sheets, student response sheets, and problem-solving ability tests. Data analysis focuses on validity, practicality, and effectiveness. The results indicate that: (1) the developed PjBOL tools include Learning Objectives Flow, Teaching Modules, and Learning Materials for geometry to enhance problem-solving skills; and (2) the PjBOL tools are of high quality as they meet the criteria of validity, practicality, and effectiveness. The test results show that the problem-solving abilities of students using PjBOL are higher in average and proportion compared to those using Discovery Learning, and there is an improvement in students' problem-solving abilities. Based on these findings, PjBOL tools effectively enhance problem-solving skills. Perangkat pembelajaran merupakan alat yang sangat penting untuk guru dalam menyampaikan materi ajar. Namun pengembangan perangkat pembelajaran yang sesuai dengan standar isi dan berkualitas masih sangat jarang dilakukan. Penelitian ini bertujuan untuk mengembangkan dan menguji kualitas perangkat Project Based Outdoor Learning (PjBOL) materi Geometri untuk meningkatkan kemampuan pemecahan masalah. Sampel penelitian yaitu peserta didik kelas VII D dan VII E SMP Negeri 2 Ungaran. Metode penelitian adalah Research and Development dengan model Four-D yakni Define, Design, Develop, Disseminate. Instrumen penelitian yang digunakan yaitu lembar penilaian ahli, lembar respon peserta didik, dan tes kemampuan pemecahan masalah. Analisis data yang dilakukan adalah kevalidan, kepraktisan, dan keefektifan. Hasil penelitian menunjukkan bahwa; (1) perangkat PjBOL yang dikembangkan meliputi Alur Tujuan Pembelajaran, Modul Ajar, dan Bahan Ajar materi Geometri untuk meningkatkan kemampuan pemecahan masalah, dan (2) perangkat PjBOL berkualitas karena memenuhi kriteria valid, praktis, dan efektif dengan hasil tes tuntas secara klasikal, rata-rata dan proporsi kemampuan pemecahan masalah peserta didik dengan PjBOL lebih dari rata-rata dan proporsi kemampuan pemecahan masalah peserta didik dengan Discovery Learning, serta terdapat peningkatan pada kemampuan pemecahan masalah peserta didik. Berdasarkan hasil penelitian, perangkat PjBOL mampu meningkatkan kemampuan pemecahan masalah.

Abstract

Creative thinking is a crucial skill in the 21st century. However, creative thinking abilities are still lacking in Indonesia, with a global creativity index of just 0.202, indicating very low level. This study seeks to evaluate the quality of GeoGebra-assisted Problem-Based Learning in enhancing students' creative thinking skills and to describe students' creative thinking abilities in relation to Self-Regulated Learning. The research method used is a mixed method. The research sample includes students from grades VIII D and VIII E at SMP Negeri 2 Ungaran. The subjects of this study are 6 students categorized by their level of Self-Regulated Learning. Quantitative data analysis involves t-tests and z-tests, qualitative data analysis involves data reduction, presentation, interpretation, and drawing conclusions. The study finds that GeoGebra-assisted Problem-Based Learning effectively enhances creative thinking skills. Students with high, medium, and low Self-Regulated Learning levels showed very good, good, and poor mathematical creative thinking abilities, respectively. Berpikir kreatif merupakan kemampuan yang sangat diperlukan di abad 21. Akan tetapi kemampuan berpikir kreatif masih sangat kurang di Indonesia, ditunjukkan dengan indeks kreativitas global Indonesia yaitu 0,202 yang tergolong sangat rendah. Penelitian ini bertujuan untuk mengetahui kualitas Problem Based Learning berbantuan GeoGebra terhadap peningkatan kemampuan berpikir kreatif siswa dan mendeskripsikan kemampuan berpikir kreatif siswa berdasarkan Self-Regulated Learning. Metode penelitian yang digunakan yaitu mixed method. Sampel penelitian yaitu siswa kelas VIII D dan VIII E SMP Negeri 2 Ungaran. Subjek penelitian yaitu 6 siswa berdasarkan tingkat Self-Regulated Learning. Analisis data kuantitatif menggunakan uji t dan uji z. Analisis data kualitatif mencakup penyederhanaan data, penyajian, interpretasi, dan penarikan kesimpulan. Hasil penelitian mengindikasikan bahwa Problem Based Learning yang didukung GeoGebra berkualitas dalam meningkatkan kemampuan berpikir kreatif serta kemampuan berpikir kreatif matematis siswa dengan tingkat self-regulated learning tinggi, sedang, dan rendah, masing-masing dengan hasil sangat baik, baik, dan kurang.
