Abstract

This study aimed to develop and evaluate Computer Science Unplugged (CS Unplugged)–based student worksheets to enhance second-grade students’ understanding of number concepts. This study employed a Research and Development approach using the ADDIE model and involved 26 second‑grade students in a limited practical trial. The developed worksheets were evaluated through expert validation, practicality testing based on teacher and student responses, and effectiveness testing using a one-group pretest–posttest design. The results indicated that the worksheets achieved a very high level of validity (media: 92.67%; content: 91.67%) and practicality (students: 91.38%; teacher: 90%). The effectiveness test showed a substantial improvement in students’ learning outcomes, with the mean score increasing from 67 in the pretest to 90.38 in the posttest, and an N-gain score of 0.73, categorized as high. These findings demonstrate that CS Unplugged–based worksheets are valid, practical, and effective for improving students’ understanding of number concepts while supporting the integration of computational thinking in elementary mathematics education.

Abstract

The purpose of this research is to describe the learning outcomes of students after the teacher uses the Teams Games Tounaments (TGT) learning method. The method used in this research is the learning outcome assessment method. The use of learning outcome tests is required as the research instrument for data collection. This research is a quantitative descriptive research. This is caused by the use of data analysis techniques using descriptive statistics. Before using the cooperative learning model of Teams Games Tournaments for students who obtained scores in the 86-100 range, 5 students with a percentage of 15.635% obtained passing grades. Meanwhile, after using the cooperative learning model of Teams Games Tournaments, there were 24 students who obtained passing grades with a percentage of 75%. The process of learning mathematics by applying the cooperative learning model of Team Game Tournament (TGT) can improve students' learning outcomes in mathematics.

Abstract

Students' mathematical representation processes in ethnomathematics contexts from the perspective of cognitive styles remain underexplored, despite the extensive body of research on mathematical representation. In addition, findings from the preliminary study indicated that many students still experienced difficulties in constructing mathematical representations when solving contextual problems. These conditions highlight the need for further investigation into how students with different cognitive styles develop mathematical representations in ethnomathematics based problem solving contexts. This study aimed to describe the mathematical representation processes of female senior high school students in solving contextual geometry problems based on Field Independent (FI) and Field Dependent (FD) cognitive styles. This research employed an exploratory descriptive qualitative approach with a case study design. Two eleventh-grade female students with high mathematical ability were selected based on extreme scores on the Group Embedded Figures Test (GEFT). Data were collected through a Problem-Solving Task (PST) based on the local wisdom of the Mbah Mayang Madu Tomb Site in Lamongan and semi-structured interviews, then analyzed using the Miles et al. (2014)model. Data trustworthiness was established through technique and time triangulation. The findings showed that the FI student demonstrated an efficient-symbolic representation process by independently identifying essential information (disembedding), internalizing sketches into mental imagery, and directly translating verbal information into symbolic representations. In contrast, the FD student exhibited a narrative-visual representation process by relying on verbal descriptions and external visual sketches to construct mathematical models. These findings indicate that cognitive style influences students' mathematical representation processes and should be considered in designing adaptive geometry learning integrated with local cultural contexts. Keywords: Cognitive Style, Ethnomathematics, Field Dependent, Field Independent, Mathematical Representation, Problem Solving.

Abstract

Meningkatnya kesadaran masyarakat terhadap pentingnya perlindungan kulit dari paparan sinar ultraviolet mendorong kebutuhan akan pemilihan produk hand body lotion bertabir surya yang tepat. Banyaknya alternatif produk di pasaran dengan karakteristik yang beragam menyebabkan konsumen perlu mempertimbangkan berbagai kriteria agar keputusan yang diambil bersifat objektif. Penelitian ini bertujuan untuk menentukan bobot kriteria serta melakukan pemeringkatan produk hand body lotion bertabir surya terbaik menggunakan kombinasi metode SAW dan TOPSIS. Penelitian ini menggunakan pendekatan kuantitatif dengan data primer yang diperoleh melalui penyebaran kuesioner daring kepada responden yang berdomisili di Kota Surabaya dan telah menggunakan minimal dua dari beberapa pilihan alternatif produk hand body lotion yang telah ditetapkan. Kriteria yang digunakan dalam penelitian ini meliputi kandungan SPF, aroma, tekstrur, harga, dan aksesibilitas produk. Hasil perhitungan menggunakan metode SAW menunjukkan bahwa kriteria kandungan SPF (K1) memiliki bobot tertinggi sebesar 0,425, menunjukkan bahwa sebagian besar responden menganggap kandungan SPF sebagai aspek paling krusial dalam pemilihan produk, sesuai dengan fungsi utama produk yaitu memberikan perlindungan terhadap sinar ultraviolet. Selanjutnya, hasil pemeringkatan menggunakan metode TOPSIS menghasilkan produk Nivea Daily Protection Sun Lotion SPF 33 PA+++ dengan nilai 0,787 menempati peringkat pertama sebagai alternatif terbaik, diikuti Herborist Juice For Skin Gluta Booster Lotion Serum SPF 30 PA+++ Pome Berry & Beetroot Extract, Grace and Glow Brightening Sun Lotion Body Serum SPF 30 PA+++, Marina Extra SPF 30, Vaseline® SPF 30 PA++ Gluta Vitamin Sunscreen Serum, dan Nivea Bright Care & Protect SPF 15. Kata Kunci: Hand Body Lotion, Sistem Pendukung Keputusan, SAW, TOPSIS.
