Abstract

ABSTRAKPenelitian ini bertujuan untuk mengkaji secara mendalam terkait dengan implementasi model Problem Based Learning (PBL) dalam pembelajaran matematika berdasar perspektif dari teori konstruktivisme. Metode yang diterapkan dalam penelitian ini adalah kualitatif deskriptif, dengan subjek meliputi key person yaitu guru wali kelas V dan seluruh siswa kelas V di SD Negeri Bakalan 02 Polokarto. Pengumpulan data dalam penelitian ini melalui teknik observasi, wawancara, dan dokumentasi. Berdasarkan hasil penelitian, guru menunjukkan kemampuan yang cukup baik dalam menerapkan lima sintaksis model Problem Based Learning (PBL). Dalam pelaksanaannya, guru memulai pembelajaran dengan menyajikan masalah kontekstual yang mengaitkan pengalaman siswa dengan materi yang dipelajari (apersepsi), mendorong eksplorasi ide, memfasilitasi diskusi dan tanya jawab, serta memberikan penguatan konsep melalui penjelasan langsung dan media video. Kegiatan pembelajaran menunjukkan keterlibatan aktif peserta didik dalam membangun pemahaman konsep secara bertahap, sebagaimana yang ditekankan dalam teori konstruktivisme. Dengan demikian, penerapan PBL terbukti dapat mendorong keterampilan berpikir kritis, pemecahan masalah, serta memperkuat pemahaman konseptual peserta didik dalam pembelajaran matematika.Kata Kunci : Problem Based Learning, Pembelajaran Matematika, Teori KonstruktivismeABSTRACTThis study aims to thoroughly examine the implementation of the Problem Based Learning (PBL) model in mathematics instruction from the perspective of constructivist theory. The research employs a descriptive qualitative method, with the subjects consisting of a key informant, the grade V homeroom teacher, and all fifth-grade students at SD Negeri Bakalan 02 Polokarto. Data collection was conducted through observation, interviews, and documentation techniques. The findings reveal that the teacher demonstrates a competent ability to apply the five syntax stages of the PBL model. In practice, the teacher initiates learning by presenting contextual problems that link students’ prior experiences with the material (aperception), encourages idea exploration, facilitates discussion and questioning, and reinforces concepts through direct explanation and video media. The learning activities reflect active student engagement in progressively constructing conceptual understanding, consistent with the principles of constructivist theory. Therefore, the implementation of PBL proves effective in fostering critical thinking skills, problem-solving abilities, and strengthening students’ conceptual comprehension in mathematics learning.Keywords: Problem Based Learning, Mathematics Learning, Constructivist Theory

In early 2023, flooding in Kwarasan Sub-District occurred twice in January and February which were the worst floods after 2007. Knowledge and attitude of preparedness are important things to have because knowledge of disaster preparedness will affect a person's attitude when a disaster occurs, which be used in the long term to minimize the impact of the disaster. This research aims to know the description of the knowledge and attitude of flood disaster preparedness of residents in Kwarasan, Grogol, Sukoharjo. The type of research used is a quantitative description with survey methods. The sample in this research was 78 heads of families in the Kwarasan sub-district using purposive sampling and stratified random sampling techniques. The results of the research on preparedness knowledge were in the good category with 76 (97.4%) respondents and 2 (2.6%) respondents in the sufficient category. Then the results of the research on preparedness attitudes were in the good category with 61 (78.2%) respondents and 17 (21.8%) respondents in the sufficient category. The Conclusion is the description of the knowledge and attitude of flood disaster preparedness is mostly in the good category.
