Abstract

The students’ mathematical literacy skills tend to be influenced by their self-regulated learning. This study aims to analyse mathematical literacy skills based on students' self-regulated learning. The research method used was descriptive-qualitative, involving 40 students from one of the Islamic junior high schools in Bandung Barat, West Java. The instruments used were a PISA-like mathematical literacy problem and a self-regulated learning questionnaire. The data analysis technique used was the Miles and Huberman model. This model uses data collection, data reduction, data presentation, and conclusion drawing. The results showed that students with high and medium level of self-regulated learning had given correct and careful answers related to managing storage on smartphones, but the students with a moderate level of self-regulated learning were careless in performing calculations. While, students with a low level of self-regulated learning have been able to understand the problem carefully, even though they have difficulty finding the right answer. This reseach can be used as one of basis for developing more effective learning strategies that support the improvement of mathematical literacy through empowering self-regulated learning.

Abstract

SNPMB is the 2023 National Selection for Admission of PTN New Students which was previously called SBMPTN (Joint Selection for State University Entrance). The SNP was formed by the Minister of Education and Culture to prepare for selection to enter PTN. This team is responsible to the Minister of Education, Culture, Research and Technology. The SNPMB test line is called SNBT (Test-Based National Selection). This policy underwent many changes from the previous SBMPTN, namely the basic science and technology ability test was replaced with a literacy test (Indonesian, English, mathematics). dedication This focus discusses the characteristics of the mathematics test both on the Scholastic Knowledge Test and the mathematical literacy test. The purpose of this exercise is to socialize SNBT information and training in dealing with quantitative reasoning and mathematical reasoning questions. The outputs achieved were Quantitative Reasoning and Mathematical Reasoning Question Drafts, draft articles on the results of community service activities. The method used was seminars and training for 30 class XII students of SMA Kartika XIX-2 Bandung. As for the results of the training, all students looked very enthusiastic in participating in coaching, this can be seen from the enthusiasm of students in working on problems with their groups and enthusiasm in asking questions and expressing their opinions, students can solve questions after getting a strategy for working on questions by the instructor.

Abstract

Kampung Adat Cikondang merupakan salah satu komunitas adat yang masih mempertahankan nilai-nilai budaya secara konsisten dalam kehidupan sehari-hari, namun potensi budaya tersebut masih jarang dikaji dan dimanfaatkan dalam konteks pembelajaran, khususnya pembelajaran matematika berbasis kearifan lokal. Penelitian ini mengkaji unsur-unsur matematika yang terkandung dalam budaya masyarakat Sunda, khususnya di Kampung Adat Cikondang, Desa Lamajang, Kecamatan Pangalengan, Kabupaten Bandung, sebagai bagian dari warisan budaya yang diterapkan dalam kehidupan sehari-hari melalui pola-pola yang khas. Budaya lokal seperti struktur rumah adat, sistem penanggalan tradisional, dan alat makan sehari-hari masih erat kaitannya dengan nilai-nilai dan simbol yang diwariskan secara turun-temurun. Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografis. Data diperoleh melalui wawancara mendalam dengan informan utama yaitu Bapak Anom Juandi selaku juru kunci generasi keempat Rumah Adat Cikondang, observasi langsung di lapangan, dokumentasi visual, serta pembuatan catatan etnografis. Hasil penelitian menunjukkan adanya konsep modulo dalam sistem penanggalan tradisional dan konsep geometri pada struktur bangunan rumah serta bentuk alat makan tradisional. Temuan ini dapat menjadi rujukan dalam pengembangan pembelajaran matematika berbasis budaya lokal, serta mendukung guru dalam merancang proses pembelajaran yang kontekstual dan bermakna.

Abstract

Coffee not only plays a role as an economic commodity, but also represents a social phenomenon closely related to calculation and ratio activities. The connection between farmers and mathematical concepts is known as ethnomathematics, which serves to bridge abstract mathematical concepts with the culture and real lives of students. This study aims to explore ethnomathematics comprehensively in the cultivation and processing stages of Tangsi Wangi coffee in Gununghalu Village and to provide a source of contextual mathematics learning. The research method used is a qualitative method with an ethnographic approach through observation, in-depth interviews, and documentation of the entire production process. The results of the study show that mathematical concepts are found in six stages, namely planting, harvesting, fermentation, drying, roasting, and brewing. Specifically, the concept of plane geometry is seen in the planting of 2×2 meter squares to optimize the land, while solid geometry is seen in the use of cylindrical drums during fermentation. Arithmetic sequences were identified in the routine harvesting schedule every 10 days. The concepts of comparison and ratio were applied to fertilizer measurements, the ratio of water and coffee powder during brewing, and the calculation of coffee bean weight reduction from 1 kg to 0.8 kg after roasting. Social arithmetic was found in the calculation of yield and determination of package weight. These findings show that local cultural practices are a rich source of mathematics learning and can be used as culture-based teaching materials for more contextual learning while supporting cultural preservation.   Kopi tidak hanya berperan sebagai komoditas ekonomi, tetapi juga merepresentasikan fenomena sosial erat dengan aktivitas perhitungan dan rasio. Keterkaitan antara petani dan konsep matematika tersebut dikenal sebagai etnomatematika, yang berfungsi menjembatani konsep matematika abstrak dengan budaya serta kehidupan nyata siswa. penelitian ini bertujuan mengeksplorasi etnomatematika secara menyeluruh pada tahapan bududaya dan pengolahan kopi Tangsi Wangi di Desa Gununghalu serta menyediakan sumber belajar matematika kontekstual. Metode penelitian yang digunakan adalah metode kualitatif dengan pendekatan etnografi melalui observasi, wawancara mendalam dan dokumentasi seluruh proses produksi. Hasil penelitian menunjukkan bahwa konsep matematika ditemukan pada enam tahapan, yaitu penanaman, pemanenan, fermentasi, dan penjemuran, roasting serta penyeduhan. Secara konkret, konsep geometri bidang tampak pada penanaman berbentuk persegi dengan jarak  meter untuk mengoptimalkan lahan, sedangkan geometri ruang terlihat pada penggunaan drum silinder saat fermentasi. Barisan aritmetika teridentifikasi pada jadwal pemanenan rutin setiap 10 hari. Konsep perbandingan dan rasio diterapkan pada takaran pupuk, rasio air dan bubuk kopi saat penyeduhan, serta perhitungan penyusutan berat biji kopi dari 1 kg menjadi 0,8 kg setelah roasting. Aritmetika sosial ditemukan pada perhitungan rendemen dan penentuan berat kemasan. Temuan ini menunjukkan bahwa praktik budaya lokal merupakan sumber belajar matematika yang kaya dan dapat dimanfaatkan sebagai bahan ajar berbasis budaya untuk pembelajaran yang lebih kontekstual sekaligus mendukung pelestarian budaya.

Abstract

Misconceptions are common among students when solving mathematics problems and, if left unaddressed, may hinder their ability to understand the material. This study seeks to design and develop diagnostic test instruments—comprising questions and questionnaires—on algebra topics using the Appsheet application. The objectives are to assess the development process, feasibility, and effectiveness of the instruments, as well as to identify challenges faced during implementation. The research employed a Design Research approach with a development studies type, consisting of two stages: preliminary design and formative evaluation. The instruments underwent a one-to-one trial with three students, a small-group trial with six students, and a field test involving 33 eighth-grade students at SMP Negeri 1 Margaasih. Expert validation rated the instruments as “feasible.” Data were gathered through documentation, tests, and interviews. The instruments included 10 three-tier multiple-choice questions, a closed-ended questionnaire with 13 items, and interviews with both teachers and students. Analysis revealed that 3.9% of students understood the concepts, 8.2% exhibited positive misconceptions, 8.4% negative misconceptions, 22.1% general misconceptions, while 57.3% showed no conceptual understanding. These findings demonstrate that the instruments effectively identified algebraic misconceptions. Challenges encountered included limited school facilities for mobile device usage and occasional errors in the application when accessed simultaneously by many users, indicating the need for updates. Nevertheless, the Appsheet-assisted three-tier diagnostic test provides a feasible and promising tool for detecting misconceptions in junior high school algebra learning
