Abstract

Developing critical thinking skills in primary mathematics remains a significant pedagogical challenge, as traditional teacher-centered instruction often fails to stimulate higher-order cognitive processing. While various methodologies have been proposed, empirical confirmation of structured problem-solving frameworks in early mathematics education warrants deeper exploration. This study aims to examine the effect of the Problem-Based Learning (PBL) model on the critical thinking skills of elementary school students in mathematics. Utilizing a quantitative approach with a quasi-experimental design, this research involved fifth-grade students from SKD State Elementary School, divided into an experimental class (grade Va, n = 30, utilizing the PBL model) and a control class (grade Vb, n = 30, utilizing conventional learning). Data were gathered through a dedicated critical thinking ability test and analyzed using descriptive statistics (mean, standard deviation, and percentage of completeness) alongside inferential parametric statistics (independent and paired-sample t-tests). The findings demonstrated that the PBL model exerts a highly positive and statistically significant effect on students' critical thinking skills. The experimental class achieved a substantially higher post-test mean score (M = 90.33) compared to the control class (M = 72.15). Additionally, the experimental group exhibited a smaller standard deviation, indicating a more homogenous and evenly distributed acquisition of critical thinking skills among students. In terms of academic mastery, the experimental class achieved a 92.12% completeness rate, significantly outperforming the control class at 68.43% (p < 0.000). These results suggest that PBL effectively fosters analytical capabilities by immersing students in real-world mathematical inquiry. Consequently, this study underscores the PBL model as a potent pedagogical alternative to mitigate low mathematical reasoning in primary education.

Abstract

Implementasi Kurikulum Merdeka di Sekolah Dasar menghadirkan tantangan, seperti kurangnya pelatihan guru, keterbatasan fasilitas, dan rendahnya akses terhadap sumber belajar. Penelitian ini bertujuan untuk mengidentifikasi strategi yang digunakan guru dalam mengatasi kendala tersebut. Metode penelitian yang dipilih adalah tinjauan literatur sistematis dengan menganalisis 75 artikel dari database Scopus dan Google Scholar yang terpublikasi periode 2014-2024. Hasil menunjukkan bahwa guru menghadapi kendala dalam menyusun perangkat ajar, memanfaatkan teknologi, serta melaksanakan pembelajaran berbasis proyek. Namun, mereka mengatasi tantangan ini dengan mengikuti pelatihan intensif, berkolaborasi dalam komunitas belajar, dan menciptakan media pembelajaran inovatif. Kesimpulannya, strategi ini efektif dalam mengurangi hambatan implementasi Kurikulum Merdeka, meskipun dukungan kebijakan dan sumber daya masih diperlukan
