Abstract

Pembelajaran abad ke-21 menuntut peserta didik memiliki kemampuan literasi sains yang memadai, khususnya dalam memahami materi kimia yang kompleks dan abstrak. Namun, hasil asesmen internasional menunjukkan bahwa kemampuan literasi sains siswa, termasuk di Indonesia, masih belum optimal. Penelitian ini bertujuan untuk menganalisis penerapan model Pembelajaran Berbasis Masalah (Problem Based Learning/PBL) dalam meningkatkan literasi sains pada pembelajaran kimia di tingkat Sekolah Menengah Atas (SMA/MA). Metode yang digunakan adalah Systematic Literature Review (SLR) dengan menganalisis artikel yang diterbitkan antara tahun 2018 hingga 2024. Berdasarkan hasil analisis diperoleh 13 artikel yang memenuhi kriteria inklusi untuk dianalisis. Hasil tinjauan menunjukkan bahwa penerapan PBL secara konsisten memperkuat pemahaman konsep sains secara mendalam dan meningkatkan keterampilan berpikir kritis serta pemecahan masalah siswa. Model pembelajaran ini tidak hanya mendukung prestasi akademik, tetapi juga membantu siswa mengaitkan ilmu yang dipelajari dengan situasi nyata, sehingga meningkatkan kualitas literasi sains yang dibutuhkan dalam pembelajaran kimia saat ini.

Abstract

The purpose of this study was to evaluate the effectiveness of STEM-Problem Based Learning (STEM-PBL) instructional materials in improving students’ chemical literacy on thermochemistry topics. This study employed a quasi-experimental method using a pretest-posttest control group design. The participants were 56 Chemistry Education students divided into an experimental class and a control class, each consisting of 28 students. Data were collected using a validated and reliable essay test (Cronbach’s α = 0.85). The results showed that the experimental class improved from 36.11 to 88.50, while the control class improved from 31.50 to 78.43. An independent samples t-test revealed a significant difference between the two groups (p < 0.05). In addition, the effect size analysis yielded a Cohen’s d value of 1.16, indicating a large effect. These findings suggest that STEM-PBL instructional materials effectively improve students’ chemical literacy, particularly in conceptual understanding, critical thinking, and problem-solving related to thermochemistry. In conclusion, STEM-PBL instructional materials are effective and feasible for enhancing chemical literacy and supporting quality, contextual, and 21st-century-oriented chemistry learning at the university level.
