Abstract

This study is based on the fact that mathematics learning materials have been unappealing, causing students to quickly become bored and saturated with the learning situation. This has resulted in students not actively participating in lectures, revealing a low level of student conceptual understanding and critical thinking in the context of functions. The research focuses on developing an interactive e-module specifically for university students on the topics of properties and operations of functions, function composition, inverse functions, and function limits, particularly for those in the Information Systems program at ITB Stikom Bali. The e-module, which integrated RME principles such as contextual problems and self-directed learning, was tested using a development research design based on the Plomp model with three methodological phases: preliminary research, development or prototyping phase, and assessment phase. The research data collection methods udes were from questionnaires for lecturer and students, observation results of lecturer and students during the trial, interviews with lecturers and students, also essay tests for students. The results of the Paired Sample T-Test, it is known that the p-value = 0.000 < 0.05, indicating a significant difference between the pre-test and post-test scores in students’ conceptual understanding and critical thinking abilities. Additionally, an RME-based e-module was developed with the following characteristics: (1) provides instructions that facilitate self-directed learning for contextual problems, supported by GeoGebra technology; (2) Incorporates RME characteristics (both “model of” and “model for”) to enhance critical thingking and conceptual understanding; (3) Not dependent on other teaching materials because its content is interconnected and self-sufficient; (4) interctive and adapts to technological advancements, making it accessible on both Android and iOS devices; and (5) Allows for independent evaluation through quiz questions and formative tes questions using Google Forms features. The study offers a model for future applications of RME in higher education.Penelitian ini didasari pada bahan belajar matematika selama ini tidak menarik, sehingga membuat mahasiswa cepat jenuh dan bosan dalam situasi belajarnya. Hal tersebut mengakibatkan mahasiswa tidak berperan aktif dalam perkuliahan, yang mengungkap rendahnya tingkat pemahaman konseptual dan berpikir kritis mahasiswa dalam konteks fungsi. Penelitian ini berfokus pada pengembangan e-modul interaktif yang dirancang khusus untuk mahasiswa pada topik sifat dan operasi fungsi, komposisi fungsi, invers fungsi dan limit fungsi, khususnya pada program studi Sistem Informasi di ITB Stikom Bali. E-modul yang mengintegrasikan prinsip-prinsip RME, seperti masalah kontekstual dan pembelajaran mandiri, diuji dengan desain penelitian pengembangan berdasarkan model Plomp dengan 3 tahapan metode, yaitu preliminary research, development/ fase prototyping, dan assessment. Metode pengambilan data penelitian yang digunakan berasal dari hasil kuesioner untuk dosen dan mahasiswa, hasil observasi terhadap dosen dan mahasiswa selama uji coba, wawancara kepada dosen dan mahasiswa, serta tes esay yang ditujukan untuk mahasiswa. Hasil uji Paired Sample T-Test, diketahui nilai p = 0.000 < 0.05, sehingga ada perbedaan yang signifikan antara skor pre-test dan post-test dalam pemahaman konsep dan kemampuan berpikir kritis mahasiswa. Selain itu, telah dihasilkan e-modul berbasis RME dengan karakteristik: (1) terdapat instruksi yang membantu belajar secara mandiri terhadap masalah kontekstual difasilitasi teknologi GeoGebra; (2) memiliki karakteristik RME (model of dan model for) untuk kemampuan berpikir kritis dan pemahaman konsep; (3) tidak tergantung pada bahan ajar lain karena memiliki sajian materi saling terkoneksi; (4) interaktif dengan mengadaptasi perkembangan IPTEK yang dapat diakses dari android dan iOS; dan (5) dapat melakukan evaluasi secara mandiri pada soal kuis dan soal tes formatif menggunakan fitur Googleform. Penelitian ini menawarkan model untuk aplikasi RME di pendidikan tinggi di masa depan.

Abstract

Covariational reasoning is closely related to the concept of functions, as both involve relationships between two quantities. Although it is useful for understanding change and interdependence between quantities, the notion of covariation is rarely introduced directly to students since it is not explicitly included in the school curriculum. This study aims to explore students’ covariational reasoning in constructing function graphs in the context of a filling bottle problem. Three aspects of covariational reasoning were analyzed: identifying variables, ways of coordinating variables, and quantifying the rate of change. This qualitative research employed a case study design and involved three 11th-grade students selected through purposive sampling. Data were obtained from students’ responses to the filling bottle task and interviews, and analyzed through data condensation, data display, and conclusion drawing. The findings indicate that (1) students had difficulty identifying the independent and dependent variables in a functional problem, especially graph, (2) students tended to rely on secondary variables when coordinating the independent and dependent variables, and (3) students’ ability to quantify the rate of change depended on their ability to identify and coordinate the two variables.

Abstract

Permasalahan dalam penelitian ini adalah rendahnya kemampuan pemahaman konsep matematis peserta didik di SD 3 Barongan, yang ditunjukkan melalui studi pendahuluan dengan rata-rata capaian hanya 36%, berada di bawah Kriteria Ketercapaian Tujuan Pembelajaran (KKTP). Proses pembelajaran yang monoton, berpusat pada guru, dan minim media kontekstual menyebabkan rendahnya partisipasi aktif serta minat belajar siswa. Urgensi penelitian ini terletak pada perlunya penerapan model pembelajaran yang mendorong keterlibatan aktif siswa dalam membangun pemahaman konsep secara mandiri dan bermakna. Model Discovery Learning berbantuan media CLEAVER (Cognitive Learning Application With Augmented Reality and Voice Recognition) yang terintegrasi dengan nilai lokal Gusjigang diharapkan mampu menjawab tantangan tersebut. Penelitian ini bertujuan untuk: (1) menganalisis kemampuan pemahaman konsep matematis siswa dengan model tersebut apakah memenuhi KKTP, (2) menganalisis perbedaan kemampuan pemahaman konsep sebelum dan sesudah pembelajaran, serta (3) menganalisis peningkatannya. Penelitian ini menggunakan pendekatan kuantitatif dengan desain one-group pretest-posttest. Subjek penelitian adalah 20 siswa kelas V SD 3 Barongan yang dipilih dengan teknik sampling jenuh. Instrumen penelitian berupa tes (pretest-posttest), dan data dianalisis menggunakan uji deskriptif kuantitati dan n-gain. Hasil penelitian menunjukkan bahwa model discovery learning berbantuan CLEAVER berbasis Gusjigang efektif meningkatkan kemampuan pemahaman konsep matematis siswa, ditunjukkan oleh 85% siswa yang mencapai KKTP, rata-rata nilai posttest sebesar 81, serta nilai gain 0,57 dalam kategori sedang.The problem in this study is the low ability to understand mathematical concepts of students at SD 3 Barongan, which is shown through a preliminary study with an average achievement of only 36%, below the Learning Objective Achievement Criteria (KKTP). The monotonous learning process, centered on the teacher, and minimal contextual media causes low active participation and interest in learning for students. The urgency of this study lies in the need to implement a learning model that encourages active involvement of students in building conceptual understanding independently and meaningfully. The Discovery Learning model assisted by CLEAVER media (Cognitive Learning Application With Augmented Reality and Voice Recognition) integrated with local Gusjigang values is expected to be able to answer this challenge. This study aims to: (1) analyze students' mathematical concept understanding abilities with the model whether they meet the KKTP, (2) analyze differences in conceptual understanding abilities before and after learning, and (3) analyze improvements. This study uses a quantitative approach with a one-group pretest-posttest design. The subjects of the study were 20 fifth grade students of SD 3 Barongan who were selected using a saturated sampling technique. The research instrument was a test (pretest-posttest), and the data were analyzed using quantitative descriptive and n-gain tests. The results showed that the Discovery Learning model assisted by CLEAVER based on Gusjigang was effective in improving students' mathematical concept understanding abilities, as indicated by 85% of students achieving KKTP, an average posttest score of 81, and a gain score of 0.57 in the moderate category.

Abstract

This study was motivated by the importance of numeracy as a core competency required to face 21st-century challenges. However, results of the Minimum Competency Assessment (AKM) reveal that more than half of vocational high school (SMK) students in Indonesia fall below the minimum proficiency level in numeracy. This condition occurs due to the limited availability of practice items for students and the limited ability of teachers to develop AKM-based questions. The aim of this study was to develop valid and reliable AKM-oriented numeracy items to support students’ numeracy improvement. The development model employed was development studies, consisting of two stages: the preliminary stage (analysis and design) and the formative evaluation stage. The research was conducted at SMK Abdurrab Pekanbaru using test and interview methods for data collection. During the formative evaluation stage, the developed items were tested on 32 students to assess validity, reliability, difficulty level, and discriminating power. The results showed that 18 test items were valid, comprising 2 multiple-choice, 4 true/false, 3 matching, and 9 essay items. Reliability testing using the KR-20 formula for objective items produced a coefficient of 0.847 (very high), while Cronbach’s Alpha for essay items was 0.873 (very high). Difficulty analysis indicated 3 easy, 14 moderate, and 1 difficult item. Discrimination analysis showed that 15 items had good discriminating power and 3 had moderate levels. In conclusion, the 18 developed items were considered suitable for measuring and improving students’ numeracy skills and can serve as a reference for teachers in designing AKM-based assessments.

Abstract

Students' mathematical problem solving ability in solving word problems still faces various challenges, especially in terms of transforming contextual problems into appropriate mathematical models. Many students have difficulty in identifying variables, compiling equations, and validating the solutions obtained, resulting in low success rates in solving complex mathematical problems. Therefore, it is necessary to conduct an in-depth analysis of students' problem solving abilities to identify the specific obstacles they face and the strategies that can be developed to overcome them. This study aims to analyze students' problem solving abilities through mathematical modeling strategies in solving word problems. A qualitative approach with a phenomenological design is used to explore students' thinking processes in depth. The subjects of the study were 31 ninth grade students of SMP Negeri 4 Klaten who were selected by purposive sampling based on variations in academic ability. Data collection was carried out through observation, written tests, and in-depth interviews, then analyzed inductively. The results showed that students who answered correctly were able to understand the context of the problem, compile mathematical models appropriately, complete calculations and interpret the results systematically, especially on questions with low to medium difficulty levels. Conversely, students who answered incorrectly had difficulty in transforming the problem into mathematical form and evaluating the final results, especially on complex questions. The conclusion of this study is that the mathematical modeling strategy is effective in improving problem solving skills, but further emphasis is needed on the transformation and reflection stages to optimize students' understanding and validation of solutions.
