Abstract

Tujuan penelitian ini adalah untuk mengetahui efektivitas model Guided Discovery Learning berbantuan GeoGebra dalam meningkatkan kemampuan pemecahan masalah matematis siswa, dengan fokus khusus pada rasa percaya diri. Penelitian ini menggunakan metodologi Sistematic Literature Review (SLR) yang meliputi tahap perencanaan, peninjauan, dan dokumentasi, dengan pengelompokan, analisis, dan penarikan kesimpulan dari data. Hasil penelitian menunjukkan guru dapat memanfaatkan pendekatan Guided Discovery Learning dengan bantuan GeoGebra untuk meningkatkan kemampuan pemecahan masalah matematis siswa dengan tetap memperhatikan tingkat kepercayaan diri. Siswa yang menggunakan model Guided Discovery Learning berbantuan GeoGebra mempunyai kemampuan pemecahan masalah matematis yang lebih baik. This research aims to determine the effectiveness of the Guided Discovery Learning model assisted by GeoGebra in improving students' mathematical problem-solving abilities, with a special focus on self-confidence. This research uses the Systematic Literature Review (SLR) methodology which includes planning, reviewing, and documentation stages, grouping, analysis, and concluding the data. The research results show that teachers can utilize the Guided Discovery Learning approach with the help of GeoGebra to improve students' mathematical problem-solving abilities while still paying attention to their level of self-confidence. Students who use the Guided Discovery Learning model assisted by GeoGebra have better mathematical problem-solving abilities.

Abstract

This quasi-experimental study investigates the effect of Project-Based Learning (PjBL) integration within an online platform on the mathematical literacy of 32 pre-service mathematics teachers at Majalengka University, Indonesia. Utilizing purposive sampling and categorizing participants based on their mathematical ability, the study assessed the impact of PjBL on enhancing mathematical literacy in real-world contexts. The one-group pretest-posttest design was adopted, and statistical analyses were performed using paired sample t-tests and one-way ANOVA. The results demonstrated a significant increase in post-test mathematical literacy scores, with initial mathematical ability positively correlating with these scores. A post hoc Least Significant Difference (LSD) test further highlighted significant differences across various initial mathematical ability levels. The study concludes that PjBL is an effective strategy for improving mathematical literacy, reflecting a meaningful distinction in pre-service primary school teachers' pretest and post-test scores. The research offers valuable insights into enhancing mathematical literacy in Indonesia, emphasizing the relevance of PjBL, particularly in the context of the pandemic, and preparing future educators to meet global challenges.
