Abstract

One of the benchmarks of individual quality is seen in numeracy literacy skills. The purpose of this study was to identify the numeracy literacy skills of grade 11 students at Warta Bakti Kefamenanu High School, Nusa Tenggara Timur, in solving numeracy literacy problems with the minimum competency assessment (MCA) instrument in integral and domain algebra. This research was descriptive qualitative. This research technique was carried out with a test in the form of MCA, identifying the variations of errors made, identifying them in the types of errors, and mapping them to numeracy literacy indicators. Instrument items were taken from previous research and modified and content validity was done. The result of data analysis shows that participants who had principal errors met the numeracy literacy indicators item 1 and item 2, participants who had operating errors met the numeracy literacy indicator item 1, and participants who had conceptual errors did not meet all numeracy literacy indicators.BAHASA INDONESIA ABSTRACT: Salah satu tolak ukur kualitas individu dilihat dari kemampuan literasi numerasi.

Abstract

This study aims to understand the cognitive development of mathematics education students based on Piaget's theory in terms of gender differences. This research method is descriptive quantitative research with the research subjects being students of mathematics education at Timor Universities. Students' cognitive development was measured using the Logical Operations Test (LOT), which consisted of 14 numbers. LOT questions are given to students, the results are analyzed and described. The results showed that the cognitive development stage for females was 19.18% in the initial concrete stage, 36.99% in the final concrete stage, 13.70% in the initial formal stage and 1.37% in the final formal stage. Male at 9.59% in the initial concrete stage, 6.85% in the final concrete stage, 9.59% in the initial formal stage and 2.74% in the final formal stage. Meanwhile, students' understanding based on seven logical operations is in low understanding for each type.Penelitian ini bertujuan untuk  mengetahui perkembangan kognitif mahasiswa pendidikan matematika berdasarkan teori Piaget ditinjau dari perbedaan jenis kelamin.

Perkembangan kognitif mahasiswa diukur dengan menggunakan Tes Operasi Logis (TOL) yang berjumlah 14 nomor. Soal TOL diberikan kepada mahasiswa, hasilnya dianalisis dan dideskripsikan. Hasil penelitian menunjukkan bahwa tahap perkembangan kognitif sebesar 19,18% tahap konkret awal, 36,99 % tahap konkret akhir, 13,70% tahap formal awal dan 1,37% tahap formal akhir bagi mahasiswa perempuan. Sementara hasil pemetaan tahap perkembangan kognitif sebesar 9,59% tahap konkret awal, 6,85 % tahap konkret akhir, 9,59% tahap formal awal dan 2,74% tahap formal akhir bagi mahasiswa laki-laki. Sementara itu pemahaman mahasiswa berdasarkan 7 operasi logis berada dalam pemahaman rendah untuk masing-masing tipe.

Abstract

The purpose of this community service activity is to provide socialization on the work of UTBK with math magic techniques in SMAN 1 and SMAN 2 Kefamenanu. Furthermore, the background of this socialization is to improve the students' reasoning ability through familiarizing themselves with students solving non-routine problems found during the implementation of UTBK, especially in mathematics. This community service was carried out from January to March 2020 with 40 participants. This activity consists of three stages starting with the assessment of the field, the implementation phase and finally the evaluation phase. In the field assessment stage, the servant determines the participants of the socialization, which is specifically for high school students of class xii, prepares administration, prepares materials and UTBK questions and then prepares a schedule. The second stage is the implementation phase in the form of a brief exposure to the UTBK, then giving samples of the UTBK questions for students to work on and scribing questions. The last stage is the evaluation stage in the form of an evaluation of the implementation of activities that have been arranged based on each task that has been given. Based on the socialization activities that have been carried out it can be concluded that these training activities increase students' knowledge about UTBK and add student skills in working on math UTBK questions . In addition, this training motivates students to be more active in learning mathematics and to be more mature in preparing for the upcoming UTBK.

Abstract

This study aims to describe student’s critical thinking ability in solving mathematical problems based on the type of representation used when solving the given problems. The study was conducted in 9th grade in junior high school in Kefamenanu, Timor Tengah Utara, NTT, Indonesia. Three respondents were selected from 28 students who were given a critical thinking ability test based on the completeness of their answers and then interviewed to clarify their answers. The instruments used in this study were test questions and interview guidelines. Test data obtained, has been analyzed based on Facione's critical thinking ability indicators which include interpretation, analysis, evaluation, inference, explanation, and self-regulation. The results showed that student with symbolic representation, fulfilled 4 indicators of critical thinking ability, namely interpretation, analysis, evaluation, and inference. Which means that symbolic representation tends to support deeper critical thinking indicators than visual or verbal. Where student with visual representation fulfilled the critical thinking skills indicators, namely analysis and evaluation. Meanwhile, student with verbal representation fulfilled 1 indicator, namely interpretation.

Abstract

Purposes: This study aims to design instruction for integer learning using the GASING method based on learning needs. Method: The participants were 79 fifth-grade students from three schools in a sub-district. The study employed design-based research in three phases; preliminary design, teaching experiment, and retrospective analysis. Data were analyzed through cognitive diagnostic assessment, skills analysis, and error analysis to identify students’ learning needs and develop learning instruction. Findings: The findings revealed that most students were at the cognitive levels of remembering and understanding when solving problems related to integer properties, number order, place value, and contextual situations. Their numeracy literacy skills were generally low, and they demonstrated conceptual, procedural, and operational errors. Based on these diagnostic results, a learning design using the GASING method supported by interactive visual aids was developed. The design emphasizes number sequences through number lines, ascending and descending order, comparing integers, and solving contextual problems involving ordered numbers. For the concept of place value, the design includes activities such as comparing integers, reading and constructing numbers, understanding integer properties, and determining place value. Significance: These findings suggest that teachers should integrate context-based instruments into daily classroom instruction to strengthen students’ conceptual understanding and problem-solving skills.
