Abstract

Based on the research objectives that have been set in the introductory section, this study explains "Difficulties of High School Students with Statistical Materials". Research shows that 18 articles published between 2015 and 2023 address high school students' difficulties with statistics. This study is a literature review. The purpose of this study is to describe, explain or describe and conclude high school students' difficulties with statistical data. In this study, the difficulties of high school students were based on research published in the form of article documents by previous researchers with statistical data. Therefore, the researcher conducted a literature review of several articles, totaling twenty articles. These articles were randomly selected from national and international journals and internet research. One of the characteristics of classroom action research is the process of conducting research in a continuous cycle, which is designed to be two cycles, and each cycle has four stages, including: 1) activity planning, 2) activity implementation, 3) observation. and interpretation of action followed by analysis and evaluation and 4) reflection. Based on the results of the research described above, students' difficulties in solving math problems related to statistics are very different. Everyone has a different way of thinking. The success of learning is determined by many factors, apart from the students themselves and the infrastructure, the teacher factor is very decisive, because the teacher determines the direction and helps students with learning difficulties.

Abstract

Pendidikan pada dasarnya adalah suatu proses yang membantu manusia untuk mengembangkan potensinya agar mampu menghadapi setiap perubahan yang terjadi. Matematika adalah suatu pembelajaran yang memiliki peranan sangat krusial dalam pendidikan maupun dalam kehidupan. Hal ini dibuktikan dari setiap pembelajaran yang ada di sekolah mewajibkan untuk mempelajari matematika. Perkembangan komputer yang pesat sangat berdampak baik pada pembelajaran matematika khususnya Geogebra. Metode penelitian yang digunakan pada penelitian ini menggunakan konsep tinjauan pustaka dengan Systematic Literature Riview (SLR). Pencarian artikel yang dilakukan oleh peneliti adalah mengenai keefektifan penggunaan aplikasi komputasi yaitu Geogebra di SMA. Database yang digunakan berdasarkan pada database yang terdapat di google scholar. Penggunaan media pembelajaran juga berpengaruh baik dalam meningkatkan efektivitas pembelajaran. Dalam konteks ini menggunakan media pembelajaran Geogebra dengan menggunakan komputer, vidio pembelajaran, maupun game petualangan matematika. Model pembelajaran yang interaktif dan juga menggunakan media pembelajaran yang menarik dapat menigkatkan pemahaman siswa dan minat belajar siswa. Oleh karenanya, penggunaan media Geogebra sesuai dengan materi matematika khususnya geometri. Penggunaan software matematika Geogebra pada pembelajaran memberikan pengaruh yang positif pada pengetahuan komputasi siswa, siswa jadi lebih semangat dalam mempelajari pelajaran karena guru bisa menyeimbangkan antara pembelajaran konvensional dan pembelajaran berbasis proyek. Penggunaan Geogebra membawa dampak yang positif sehingga akan terus berlanjut dilakukan dalam pembelajaran, penggunaannya mudah diakses oleh siswa maupun guru karena fitur yang disediakan dapat diakses dengan gratis.

Abstract

This study addresses the challenge of low levels of mathematical communication and critical thinking among students, often stemming from the widespread use of traditional, teacher-centred instructional methods. The objective of this research is to examine the impact of the Project-Based Learning (PjBL) model on seventh-grade students' mathematical communication and critical thinking skills in statistics. A quasi-experimental design with a Nonequivalent Control Group was applied. Participants included 35 students in the experimental group (Class VII-3, using PjBL) and 35 students in the control group (Class VII-5, using conventional methods) at MTs Al-Jam'iyatul Washliyah Tembung. Data was collected using tests for critical thinking and observation sheets for mathematical communication skills. The results showed significantly higher average scores in the experimental group compared to the control group for both skills. Specifically, the mean scores for mathematical communication were 88.05 (experimental) versus 48.84 (control), and for critical thinking were 74 (experimental) versus 50.28 (control). The Independent-Samples t-Test confirmed significant differences (Sig. 2-tailed = 0.000 < 0.05) for both skills, while ANOVA (F = 43.634, Sig. = 0.000 < 0.05) further confirmed PjBL's significant positive effect on learning outcomes. These findings demonstrate that the Project-Based Learning (PjBL) model is effective in enhancing students' mathematical communication and critical thinking skills.
