Abstract

This research was motivated by the lack of media that supports the learning process. In addition, students want media that is fun and enjoyable. One solution is to design a monopoly game, so that students will be motivated to learn. The purpose of this research is to produce a valid monopoly game for flat shape material. This research is a development study using the Plomp model. The Plomp model consists of three stages, namely preliminary research, prototyping, and assessment. Data were collected through observation, interviews with educators and students, and validity questionnaires. This research only consisted of two stages, namely the preliminary research stage, which was a preliminary analysis in the form of a needs analysis, curriculum analysis, student characteristics analysis, concept analysis, and literature review analysis. In the prototyping stage, the product was designed based on the needs analysis data. Next, the product was validated by experts in the field. From the validation process, assessments were obtained from experts in material, media, and language, namely 85%, 88%, and 93%, which were categorized as highly valid.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh growth mindset terhadap kemampuan pemecahan masalah matematika siswa kelas VII di UPT SMP Negeri 1 Linggo Sari Baganti. Jenis penelitian yang digunakan adalah penelitian kuantitatif dengan desain regresi linear sederhana untuk mengetahui pengaruh antara variabel bebas dan variabel terikat. Teknik pengumpulan data yang digunakan adalah metode angket dan tes dengan sampel penelitian sebanyak 26 siswa kelas VII.U. Berdasarkan hasil analisis deskriptif, diperoleh skor growth mindset siswa dengan nilai tertinggi 76, nilai terendah 61, dan rata-rata 68,42 yang berada pada kategori sedang. Hasil tes kemampuan pemecahan masalah matematika siswa menunjukkan nilai tertinggi 98, nilai terendah 22, dan rata-rata 76,46 yang berada pada kategori sedang hingga tinggi. Hasil penelitian menunjukkan bahwa growth mindset berpengaruh positif terhadap kemampuan pemecahan masalah matematika siswa, artinya semakin tinggi growth mindset siswa maka kemampuan pemecahan masalah matematika juga cenderung meningkat. Namun demikian, kemampuan pemecahan masalah matematika siswa tidak hanya dipengaruhi oleh growth mindset, melainkan juga dipengaruhi oleh faktor lain di luar penelitian ini.

Abstract

Mathematical communication skills are an important competence in mathematics learning, especially in the topic of Systems of Linear Equations in Two Variables, because students are required to express ideas, construct mathematical models, and explain solution steps systematically. However, these skills are still not optimal and are assumed to be related to affective factors, one of which is self-confidence. This study aimed to determine the relationship between students’ self-confidence and their mathematical communication skills among ninth-grade students of MTs PP Darussalam. This research employed a quantitative approach with a correlational design. The subjects of the study were 27 ninth-grade students selected using saturated sampling. Data were collected through a self-confidence questionnaire and a mathematical communication skills test. Data were analyzed using descriptive statistics and the Pearson Product-Moment correlation test after meeting the assumptions of normality and linearity. The results showed that the average self-confidence score of the students was in the moderate category with a score of 52.56, while the average mathematical communication skill score was also in the moderate category with a score of 70.22. The Pearson correlation test indicated a significant positive relationship between self-confidence and mathematical communication skills, with a correlation coefficient of 0.62 and a significance value of 0.001. These findings imply that improving students’ self-confidence should be an important concern in mathematics learning because it can support the optimal development of students’ mathematical communication skills.

Abstract

Abstract This study aims to analyze and compare the mathematical literacy skills of seventh-grade students at SMP Negeri 3 Lengayang between class VII A and class VII B. Mathematical literacy refers to an individual’s ability to formulate, apply, and interpret mathematics in various real-life contexts. This research employed a quantitative approach using a descriptive comparative method. The research instrument was a mathematical literacy test consisting of contextual essay questions developed based on the Programme for International Student Assessment (PISA) mathematical literacy indicators. The data were analyzed using descriptive statistics and an independent samples t-test. The results showed that the average mathematical literacy score of students in class VII A was higher than that of students in class VII B. The t-test results indicated that the calculated t-value exceeded the critical t-value at the 0.05 significance level, indicating a significant difference in mathematical literacy skills between students of class VII A and class VII B. Keywords: mathematical literacy, comparative analysis, t-test, junior high school students.

Abstract

Mathematical literacy is an essential competence in mathematics learning because it requires students to formulate, use, and interpret mathematical concepts in various real-life contexts. However, international studies indicate that Indonesian students’ mathematical literacy remains relatively low. One factor presumed to influence this ability is self-efficacy, namely students’ belief in their own ability to complete tasks. This study aimed to analyze the effect of self-efficacy on mathematical literacy skills in the topic of geometric transformations among ninth-grade students at SMP Negeri 1 Linggo Sari Baganti. This research employed a quantitative approach with a causal associative design using an ex post facto method. The research subjects were 30 students from class IX.4 selected through purposive sampling. Data were collected using a self-efficacy questionnaire and a mathematical literacy test in the form of contextual essay questions. Data analysis was conducted using normality and linearity tests, Product Moment correlation, and simple linear regression. The results showed that there was a positive and significant effect of self-efficacy on students’ mathematical literacy skills. Students with higher self-efficacy tended to demonstrate better ability in modeling problems, applying geometric transformation concepts, and interpreting solution results. These findings imply that improving students’ self-efficacy should be a concern in mathematics learning in order to support the enhancement of their mathematical literacy skills.
