Abstract

Test-Based National Selection demands students' readiness not only in material mastery, but also in critical thinking skills and high-level problem solving. Tutoring institutions have become a popular choice to improve students' readiness to face the selection, but evaluating students' readiness objectively and adaptively is still a challenge. This research develops a decision support system model based on Mamdani type fuzzy inference system to evaluate students' readiness for Test-Based National Selection. Two main indicators are used as linguistic input variables, namely study frequency and try out results. The modeling process is carried out qualitatively with the stages of fuzzification, IF-THEN rule base formulation, Mamdani inference, and defuzzification using the centroid method. Data is processed with the help of Microsoft Excel as a fuzzy logic processing tool. The results of the implementation on 30 students showed that the system was able to classify the level of readiness into three categories: not ready, moderately ready, and ready, with high precision and flexibility to data uncertainty. The findings suggest that fuzzy models can be used as adaptive and contextualized evaluation tools in tutoring environments, and support data-driven instructional decision-making.

Abstract

Penelitian ini bertujuan mengkaji pemahaman konsep statistika siswa SMK melalui penerapan model Self-Directed Learning (SDL) berbantuan TikTok dengan mempertimbangkan perbedaan tipe kepribadian introvert dan ekstrovert. Pendekatan penelitian menggunakan metode kualitatif deskriptif dengan subjek empat siswa kelas X Akuntansi SMK PGRI 1 Sukodadi, yang ditentukan melalui teknik purposive sampling berdasarkan hasil angket Eysenck Personality Inventory (EPI). Data dikumpulkan melalui angket kepribadian, tes pemahaman konsep, dan wawancara semi-terstruktur, kemudian dianalisis menggunakan kerangka Miles dan Huberman yang meliputi reduksi, penyajian, dan penarikan simpulan. Hasil penelitian menunjukkan bahwa siswa introvert mampu memenuhi empat indikator pemahaman konsep, yaitu menyatakan ulang konsep, mengelompokkan objek, memberikan contoh dan non-contoh, serta menerapkan konsep dalam pemecahan masalah. Namun, mereka belum optimal dalam representasi matematis, merumuskan syarat perlu dan cukup, serta menentukan prosedur penyelesaian. Siswa ekstrovert juga memenuhi empat indikator dengan keunggulan pada representasi matematis, tetapi mengalami kesulitan dalam merumuskan syarat perlu dan cukup, memilih prosedur yang tepat, serta mengaplikasikan konsep pada konteks nyata. Temuan ini menegaskan bahwa tipe kepribadian berpengaruh terhadap variasi capaian indikator pemahaman konsep matematis dalam pembelajaran mandiri berbasis media digital. Penelitian ini memberikan kontribusi teoretis berupa bukti empiris hubungan kepribadian dengan pemahaman konsep, serta kontribusi praktis sebagai acuan bagi guru dalam merancang strategi pembelajaran berdiferensiasi sesuai karakteristik siswa.

Abstract

This study aims to develop TAPENA media (Equivalent Fraction Table) based on the 4D model to improve the understanding of fraction concepts among fourth-grade students at SDN 1 Made Lamongan. The research employed the Research and Development (R&D) method using the 4D model (Define, Design, Develop, Disseminate). The research subjects were 28 fourth-grade students. Data were collected through observations, tests, and questionnaires. The results showed that after material explanation without media, only 5 students (17.86%) understood the concept, whereas after using TAPENA media, all 28 students (100%) understood the concept of equivalent fractions. TAPENA media presents a table that makes it easier for students to see the relationship between fractions visually. The media validity from material experts reached 86.5% (very valid), and from media experts 88.2% (very valid). The practicality test by teachers obtained 90.5%, and by students 94.8%. These findings prove that TAPENA media is valid, practical, and effective in improving the understanding of fraction concepts. The implication is that TAPENA media can be used as an innovation in mathematics learning in elementary schools. It is recommended that teachers integrate TAPENA into learning activities to motivate students.

Abstract

Mathematics teaching in elementary schools, particularly regarding the topic of mass and quantity units, still faces challenges in helping students master abstract concepts and unit conversion processes. This situation impacts the lack of conceptual understanding and student participation in the learning process, so clear and engaging learning media are needed to support valuable teaching mechanisms. This study aims to produce ROMAKU (Mass and Quantity Wheel) learning media that can support students when learning the concept of mass and quantity units in an easier, more organized way, and in accordance with student characteristics. This study uses a Research and Development approach with an adaptation of the ASSURE model consisting of six stages: Analyzing Learners, Stating Objectives, Determining Methods, Media, and Materials, Optimizing Media and Materials, Requiring Learning Involvement, and Evaluating and Revising. Study participants consisted of elementary school students studying material on mass and quantity units. Data collection methods included validation sheets from media and material experts, student response questionnaires, and assessment of learning outcomes. Data were analyzed using descriptive quantitative methods with a Likert scale and percentages to assess the validity, practicality, and effectiveness of the media. Research results show that ROMAKU media meets validity standards based on expert assessments with an average percentage of 78% in the high category, is practical based on student responses, and is effective in improving students' conceptual understanding. ROMAKU media is able to help students convert units and solve contextual problems more accurately and independently.

Abstract

Sexual crimes inflict prolonged physical, psychological and social impacts on victims. Indonesia's criminal law reform through the Law on Sexual Violence Crimes and the National Criminal Code (KUHP) demonstrates a paradigm shift toward victim protection through a victim-centered justice approach. This article analyzes the implementation of this paradigm in handling sexual crimes in Indonesia. The findings indicate that although the normative framework has accommodated the victims' interests and rights, judicial practices still face challenges in the form of secondary victimization. Furthermore, a gap remains between statutory regulations and their enforcement by law enforcement authorities in providing effective protection to victims. Therefore, it is necessary to formulate and implement standard operating procedures (SOPs) oriented toward victim protection and recovery at every stage of the criminal justice process.

Abstract

Developing students' mathematical conceptual understanding in geometry remains challenging because students with different cognitive styles construct concepts through different learning processes, while differentiated instruction has rarely been examined from this perspective. This study investigated the implementation of differentiated instruction in quadrilateral learning and explored the conceptual understanding of Field Independent (FI) and Field Dependent (FD) students. A qualitative descriptive design involved 28 Grade VII-C students. The Group Embedded Figures Test (GEFT) classified cognitive styles, and four participants (two FI and two FD) were selected for in-depth analysis using a conceptual understanding test, semi-structured interviews, and classroom observations. The findings showed that differentiated instruction supported conceptual understanding through learning pathways aligned with students' cognitive characteristics. FI students demonstrated more analytical reasoning, whereas FD students benefited from visual representations, structured worksheets, and teacher scaffolding. These findings extend differentiated instruction research by integrating cognitive style and provide practical guidance for adaptive geometry instruction.

Abstract

ABSTRACT Mathematical conceptual understanding plays an important role in helping students connect mathematical knowledge with problem solving, including contextual problems involving triangles. This study aims to describe the mathematical conceptual understanding of low-ability junior high school students in solving contextual triangle problems based on Van Hiele Theory. This study employed a qualitative approach with a descriptive-exploratory design. Two subjects were selected through purposive sampling from Grade VIII B students at MTs Putra Putri Simo Karanggeneng based on the results of a pretest. Data were collected through a pretest, conceptual understanding tests, semi-structured interviews, and documentation, and were analyzed through data reduction, data presentation, and conclusion drawing and verification. The results showed that both subjects experienced difficulties particularly in transforming representations, recognizing the meaning and interpretation of concepts, and identifying the properties and conditions of triangle concepts. Based on the analysis results, one student (R1) was at Level 0 (visualization), while one student (R2) was at Level 1 (analysis). The study concludes that differences exist in the characteristics of conceptual understanding and geometric thinking development among low-ability students when solving contextual triangle problems.

Abstract

Students' mathematical problem solving in statistical materials tends to be low due to less relevant learning approaches and lack of learning adjustment to students' personality types. This research was conducted with the aim of describing students' mathematical problem solving through a deep learning approach assisted by Zep Quiz on statistical material based on introverted personality. The research method used is qualitative descriptive. The subjects of this study were two students of class X-2 who were selected from 35 students using purposive sampling techniques based on the results of the questionnaire on the students' personality type. The data analysis technique uses the Miles and Huberman model, namely data condensation, data presentation, and conclusion drawing. The results of this study found that students with introverted personalities showed very optimal performance in solving mathematical problems according to Polya. The first introverted student (IN-1) was proven to master all stages of analysis from understanding the problem completely, planning steps, completing calculations consistently, to systematically reviewing answers. In line with this, the second introverted subject (IN-2) also showed equally high achievement on each of the Polya indicators tested. ABSTRAK Pemecahan masalah matematis siswa pada materi statistika seringkali tidak maksimal karena metode pembelajaran yang tidak sesuai dan kurangnya penyesuaian dengan tipe kepribadian siswa.

Abstract

Creative thinking is an essential competency in 21st-century mathematics education. However, observations and interviews with mathematics teachers at MTs Nurul Jadid Banjarmadu revealed that students still have difficulty solving open-ended problems that require diverse strategies and the development of creative ideas. Although personality type is known to influence creativity, studies examining the creative thinking profiles of sanguine students when solving open-ended social arithmetic problems remain limited. This study employed a descriptive qualitative approach using the interactive analysis model. The subjects were two sanguine-type students (S-1 and S-2) selected from 26 seventh-grade students through the Florence Littauer personality questionnaire. Data were collected through social arithmetic open-ended tests and semi-structured interviews, and then analyzed using four creative thinking indicators: fluency, flexibility, originality, and elaboration. Method triangulation was conducted by comparing the participants' written responses with their interview explanations. The findings indicate that sanguine students met the fluency indicator by generating four valid answer pairs and the flexibility indicator by using two different solution strategies. However, neither subject demonstrated originality, as they relied on common strategies, nor did they demonstrate elaboration, due to incomplete verification of solution steps. The patterns observed in both participants indicate that spontaneity and enthusiasm can foster the generation of numerous ideas, whereas a focus limited to verification and detailed explanation can hinder elaboration during mathematical problem-solving. Therefore, teachers are encouraged to provide structured verification activities and guided solution frameworks to enhance originality and elaboration while maintaining fluency and flexibility.
