Abstract

Mathematical problem-solving ability is one of the essential competencies students need to master; however, in reality, many students still face difficulties in developing this skill. One effort to improve it is through the implementation of Case Base Learning while also considering affective factors such as curiosity. This study aims to examine the effect of Case Base Learning and curiosity on students’ mathematical problem-solving ability. The research employed a quantitative approach with a quasi-experimental design. The population consisted of all ninth-grade students of SMP Negeri 1 Abung Semuli, with a total sample of 65 students selected using cluster random sampling. The sample consisted of two classes: class IX H as the experimental class, which applied Case Base Learning, and class IX F as the control class, which applied Direct Instruction. The instruments used were a mathematical problem-solving test and a curiosity questionnaire. Data analysis was conducted using two-way ANOVA with prerequisite tests, namely normality and homogeneity tests. The results of the study revealed that: (1) Case Base Learning was more effective than Direct Instruction in improving students’ mathematical problem-solving ability, (2) curiosity had a significant role in enhancing students’ mathematical problem-solving ability, and (3) there was no interaction between Case Base Learning and curiosity in influencing students’ mathematical problem-solving ability.

Abstract

Kompetensi dasar yang dapat dicapai oleh siswa, seperti analisis matematis, berpikir reflektif, dan kreatif, memainkan peran penting dalam mendukung proses pembelajaran. Penelitian ini bertujuan untuk mengeksplorasi bagaimana kemampuan dalam analisis matematis, berpikir reflektif, dan kreativitas memengaruhi siswa yang terlibat dalam pembelajaran kooperatif, khususnya dengan mengimplementasikan model bertipe think pair share bersama metode ekspositori. Studi ini melibatkan 63 siswa yang terbagi menjadi dua kelas, yaitu kelas eksperimen dengan 32 siswa yang menerapkan model pembelajaran kooperatif tipe think pair share dan kelas kontrol dengan 31 siswa yang menerapkan metode ekspositori. Teknik pengambilan sampel dilakukan dengan menerapkan metode cluster random sampling, dengan tes sebagai metode pengumpulan data utama. Analisis data melibatkan berbagai uji diantaranya validitas, tingkat kesulitan, daya pembeda, reliabilitas, serta uji untuk normalitas dan homogenitas. Melalui penerapan uji MANOVA untuk pengujian hipotesis, peneliti menyimpulkan bahwa terdapat dampak dari keterampilan menganalisis matematis, berpikir reflektif dan kreatif pada siswa yang terlibat dalam pembelajaran kooperatif menggunakan model pembelajaran tipe think pair share bersama dengan metode ekspositori. Siswa yang menggunakan model pembelajaran kooperatif tipe think pair share akan memiliki efisiensi berpikir lebih tinggi dan memiliki akses terhadap metode pembelajaran terkini

Abstract

Tujuan dari penelitian ini yakni untuk mengetahuiagaimana literasi lingkungan dan literasi digital mempengaruhi kemampuan berpikir kritis matematika di SMP Negeri Kecamatan Jati Agung. Penelitian ini menggunakan analisis regresi linier berganda dengan taraf signifikansi = 0,05. Analisis ini menggunakan tiga uji, yaitu; uji t, uji F, dan uji koefisien determinasi (R2). Hasil uji t didapat nilai p-value = 0,018 pada tes literasi lingkungan, sehingga dapat dinyatakan H0 ditolak, yang artinya terdapat pengaruh dari litarisi lingkungan terhadap kemampuan berpikir kritis, selanjutnya antara kemampuan literasi digital dengan berpikir kritis matematis mempunyai nilai p-value yakni 0,021 sehingga H0 ditolak yang berarti terdapat dampak yang drastis. H0 ditolak . Hasil dari uji F dengan taraf signifikansi a = 0,05 dan p-value 0,005 memperlihatkan jika literasi lingkungan dan literasi digital mempunyai hubungan terhadap kemampuan berpikir kritis matematis murid. Hasil pada koefisen determinasi diperoleh nilai R square sebesar 0,042, artinya pengaruh dari variabel independen terhadap variabel dependen sebesar 4,2%.

Abstract

This study aims to develop a mathematical model to analyze the impact of the revitalization program at Koga Market, Bandar Lampung, on traders’ profits by examining the influence of sales volume, marketing costs, staple-goods prices, and infrastructure costs. Using a quantitative survey approach involving 50 randomly selected traders, data were collected through questionnaires, interviews, and documentation, and analyzed using descriptive statistics, classical assumption tests, and multiple linear regression. The results show that staple-goods prices and infrastructure costs have a strong and significant positive effect on traders’ profits, marketing costs also contribute positively, while sales volume shows a negative but insignificant effect. All classical assumptions were met, indicating that the regression model is valid for explaining the profit determinants. The findings confirm that market revitalization has generated measurable economic benefits through improved infrastructure and stable commodity prices, suggesting the need for continued infrastructure enhancement and strengthened marketing strategies to further support traders’ economic sustainability.
