Abstract

Kesalahan konseptual dalam belajar aljabar, yang sering disebabkan oleh kesalahpahaman terhadap konsep dasar seperti variabel dan koefisien, menjadi penghalang signifikan bagi siswa. Penelitian ini bertujuan untuk mendeskripsikan jenis kesalahan konseptual yang sering dilakukan siswa saat belajar aljabar dan faktor-faktor yang mempengaruhinya. Penelitian menggunakan pendekatan deskriptif kualitatif dengan melibatkan 25 siswa kelas XI MIPA yang akan menjadi subjek penelitian di MA Mathla'ul Anwar Kedondong pada semester ganjil tahun 2024/2025. Data dikumpulkan melalui ujian tertulis yang terdiri dari lima soal uraian. Analisis data menggunakan metode berikut: 1) mengoreksi jawaban siswa; 2) menemukan kesalahan dalam jawaban siswa; 3) menghitung persentase kesalahan; 4) menganalisis data hasil perhitungan secara deskriptif; dan 5) membuat kesimpulan. Hasil penelitian menunjukkan bahwa persentase kesalahan siswa adalah: 1) Kesalahan yang disebabkan oleh kurangnya ketelitian dan kecerobohan sebesar 48%; 2) Kesalahan yang berkaitan dengan keterampilan dalam melaksanakan proses sebesar 32%; 3) kesalahan konseptual siswa sebesar 60%. Kesalahan konseptual siswa dapat dibagi menjadi dua kategori utama (indikator), yaitu kesalahan yang disebabkan oleh kurangnya pemahaman konsep terkait soal yang diberikan dan kesalahan akibat ketidakmampuan dalam menentukan hubungan yang ada dalam masalah. Faktor-faktor yang mempengaruhi kesalahan tersebut antara lain terburu-buru, kurangnya latihan, pemahaman yang terbatas, serta kurangnya konsentrasi saat mengerjakan soal.

Abstract

The purpose of this study is to explore Ethnomathematics of Geometry concepts in Kedatun Keagungan traditional house architecture. It is hoped that students will more easily explore understanding of mathematical abstractness through visual representations in familiar cultural forms. Learning mathematics by linking the surrounding culture so that learning is more meaningful for students. This research is a qualitative research with an ethnographic approach. Data collection techniques begin with observation, compiling and validating instruments, documentation studies and FGD. Data analysis technique uses the Spradley model. Based on the research results, it was found that Ethnomathematics in the Kedatun Keagungan traditional house has applied mathematical concepts both to the components of the house building and the ornaments inside which include: (1) the concept of geometry which consists of shapes, shapes and angles, (2) the concept of Geometry Transformations consisting of Symmetrical properties, Translation properties, Reflections, and Dilations. The results of this research can be used as a reference in developing teaching materials on Geometry material so that learning becomes more meaningful.

Abstract

Considering the growing importance of mathematical literacy in the 21st century, this study provides an initial insight into improving future STEM-based learning models in mathematics education. The research aims to describe students’ mathematical literacy skills as a foundation for enhancing STEM-oriented instruction in higher education. The participants were students of the Mathematics Education Study Program enrolled in a Calculus course at a university in Lampung, Indonesia. Data were collected through a mathematical literacy test and a student response questionnaire. Data were analyzed using an independent sample t-test to identify students’ strengths and weaknesses in mathematical literacy. The results show that students’ mathematical literacy remains low. The average score was 20.67, with nearly half of the students (46.67%) scoring below the mean. The highest achievement was found in the problem formulation indicator (57.78%), followed by reasoning (49.33%), interpretation and representation (46%), and application (38.33%) as the lowest. These findings suggest that students are relatively capable of formulating mathematical problems but struggle to interpret, represent, and apply them in real-life contexts. Overall, students tend to focus on procedural calculations rather than meaningful connections between mathematics and real situations. Therefore, STEM-based learning innovations are needed to strengthen conceptual understanding and problem-solving skills. The positive student responses indicate that the approach used in this study successfully fostered engagement, motivation, and deeper mathematical literacy.

Abstract

This research aims to develop and evaluate the effectiveness of a Flipbook Augmented Reality (AR) application based on local wisdom from Lampung in enhancing students' mathematical literacy in geometry topics. The method used is a developmental study with a design research approach, employing the 1993 Tessmer model, which consists of the preliminary, formative evaluation, and prototyping, including three parts: expert review, one-to-one, and small group, followed by the field test stage. The subject of the study was an eighth-grade student at Junior High School in Bandar Lampung. The instruments used were mathematical literacy tests and student response questionnaires. The results of expert validation indicate that the product falls into the excellent category, with a practicality level reaching 83.1%. The results of the binomial test show that more than 70% of students achieved learning mastery. The highest achievement in mathematical literacy was found in the communication indicator (88.15%). The research has proven effective in improving students’ mathematical literacy. Flipbook AR can serve as a contextual learning alternative that integrates technology and local culture to meaningfully reinforce students' understanding of mathematical concepts.
