Abstract

This study aims to explore the cognitive processes of PGSD students in solving algebraic literacy problems. This study is qualitative in nature, using a case study approach. The subjects in this study were two PGSD students with high mathematical ability. The instruments used were one algebraic literacy question and interview guidelines. The methods used for data collection were tests, interviews, and documentation. The data analysis techniques used included data condensation, data presentation, and conclusion drawing. The results of this study indicate that PGSD students in the high category have mature algebraic literacy. SKT1 demonstrates analytical, reflective, and systematic cognitive processes in interpreting information and explicitly constructing mathematical models. Meanwhile, SKT2 displays efficient, strategic, and abstractive thinking with logical model simplification. Both are able to relate calculation results to the problem context in a meaningful way, reflecting the integration of conceptual, procedural, and reflective understanding in algebraic thinking.

Abstract

Penelitian ini bertujuan menguji efektivitas MATH DLP (Deep Learning Power) dalam meningkatkan keterampilan berpikir kritis siswa pada pemecahan masalah matematika. Metode yang digunakan adalah quasi-eksperimen satu kelompok dengan desain pretest–posttest pada 21 siswa. Keterampilan berpikir kritis diukur melalui tes pemecahan masalah sebelum dan sesudah intervensi, lalu dianalisis menggunakan uji t sampel berpasangan. Hasil menunjukkan peningkatan skor yang signifikan setelah penerapan MATH DLP: pra-tes M = 63,10 (SD = 12,19) dan pasca-tes M = 77,38 (SD = 6,45), dengan selisih rata-rata 14,28 poin (t(20) = −8,076, p < 0,001). Ukuran efek tergolong besar (Cohen’s d = 1,76), menandakan dampak praktis yang kuat. Temuan ini mengindikasikan bahwa MATH DLP efektif untuk memperkuat berpikir kritis siswa melalui pembelajaran mendalam dan pemecahan masalah yang berpusat pada siswa.
