Abstract

This study aims to analyze the effect of the Discovery Learning model assisted by ELKPD on the ability to understand mathematical concepts of junior high school students. This study uses three-dimensional shapes with flat sides. The method used in this study was quantitative research with a Quasi Experiment design. The sampling technique used purposive sampling. The data collection technique was carried out by conducting a description test to measure the ability to understand mathematical concepts. The Discovery Learning model assisted by ELKPD was applied to class VIII.3 as the experimental class, while class VIII.1, as the control class, only applied the Discovery Learning model without using ELKPD. The ELKPD used in this study is based on the EdForm website. EdForm is a teaching material used to attract student"™s attention and can improve learning activities in the classroom. The results showed that the average understanding of the concept of students based on the post-test score of the experimental class was 85,20, higher than that of the control class, which was only 73,06. The t-test results obtained a significance value (sig.) of 0.000. This shows sig.

Abstract

Matematika merupakan salah satu mata pelajaran yang berperan dalam perkembangan kemampuan berpikir kritis dan logis siswa. Namun, bagi banyak siswa, matematika bukan hanya tantangan akademis, tetapi juga sumber kecemasan yang signifikan. Tujuan kajian ini untuk merangkum berbagai penelitian terkait kecemasan matematika dan hasil akademik siswa. Kajian ini menggunakan tinjauan literatur sistematis dengan tahapan PRISMA, pengumpulan data memanfaatkan basis data akademis seperti Scopus dan Google Scholar rentang tahun 2019-2024, kriteria inklusi dan eksklusi terapkan dalam tahapan ini. Temuan ini mendapatkan hubungan negatif yang signifikan antara kecemasan matematika dan prestasi akademik siswa. Semakin tinggi tingkat kecemasan matematika, semakin rendah kinerja siswa dalam bidang tersebut. Faktor-faktor seperti efikasi diri rendah, tekanan sosial, metode pengajaran, dan pengalaman negatif sebelumnya memperkuat hubungan ini. Namun, penelitian saat ini masih terbatas oleh desain cross-sectional, populasi yang homogen, dan variasi instrumen pengukuran. Rekomendasi untuk penelitian masa depan mencakup penggunaan desain longitudinal, pendekatan campuran, keberagaman populasi, standarisasi instrumen, serta fokus pada pengembangan intervensi yang efektif untuk mengurangi kecemasan. Hal ini penting untuk menciptakan lingkungan pembelajaran yang lebih inklusif dan mendukung keberhasilan akademik siswa.

Abstract

Students need to have mathematical problem solving abilities to be able to solve complex mathematical problems. Mathematical problem solving abilities consist of understanding, planning, solving, and reviewing. These abilities can be trained through the application of appropriate learning models. One model that can be used is the problem based learning model. This study aims to determine the effect of the problem based learning model using contextual student worksheet on the mathematical problem solving ability of the junior high school students. This type of research is a quasi-experimental research with a research design of One Group Pretest-Posttest Design. The population in this study were all seventh grade students of SMP Negeri 12 Lebong in the 2021/2022 academic year. The sample in this study were class VIIA students, totaling 23 students as an experimental class taken by purposive sampling technique. The instrument used in this study was a problem-solving ability test sheet in the form of description questions. Data analysis using descriptive and inferential statistics. The results showed that there were differences in students' math solving abilities before and after learning. Based on the research results, it can be concluded that there is a significant influence on the Problem Based Learning model on mathematical problem solving in class VII students of SMP Negeri 12 Lebong.

Abstract

Indonesia’s low numeracy performance in international assessments highlights the need for more effective and engaging instructional strategies. This study analyzed the influence of the Quizizz application on supporting the numeracy ability of junior high school students in Bengkulu City. Using a quantitative approach, data were collected from 70 students through a Likert-scale questionnaire measuring ten indicators of Quizizz utilization. Multiple linear regression analysis using SPSS 25 revealed that the model was statistically significant (F = 3.303; p = 0.002), with the independent variables collectively explaining 36.3% of the variance in numeracy skills (Adjusted R² = 0.253). Two indicators—conceptual understanding (x1) and critical–creative thinking (x5)—significantly affected numeracy ability, whereas other indicators showed no partial influence. The model met classical assumption requirements, including linearity and homoscedasticity. These findings confirm that Quizizz is an effective digital learning tool that enhances students’ numeracy through interactive and motivating learning experiences.

Abstract

This systematic literature review analyzes international evidence on proportional reasoning (PR) in K–12 education and teacher training. We synthesized eight studies and identified four key patterns. Contexts with hands-on activities help students transition from intuitive to formal strategies. Students often succeed with probability ratios, but struggle with visual biases. Example-based practice with self-explanation improves probabilistic reasoning, especially for less prepared students. Finally, diagnostic tools such as construct maps are useful for tracking student progress from "combined unit" to "multiplicative comparison" understanding. Our review recommends designing a clear progression for ratios, rates, and probabilities; teaching anti-bias strategies; embedding routines of example problems; and using construct map-guided assessments. This synthesis provides a clear action lens to improve PR instruction by integrating student cognition, task design, and teacher practices.
