Abstract

Algebraic reasoning is essential for students to develop thinking systematically and analytically to conclude. This study analyzes students' algebraic reasoning levels about learning limit functions. The method used is a qualitative method with data collection techniques using algebraic reasoning tests on 23 first-semester students of the mathematics education study program and interviews conducted with one student from each of the high, medium, and low levels. Data analysis techniques in this study consist of data collection, reduction, presentation, and conclusions. In completing the algebraic reasoning test, students with high levels can fulfill four of the five indicators of algebraic reasoning. Students with a moderate level of algebraic reasoning can fulfill three of the five indicators of algebraic reasoning. Students with a low level of algebraic reasoning can fulfill four of the five indicators of algebraic reasoning. Students with high, medium, and low algebraic reasoning cannot find patterns, create patterns, and generalize patterns. Keywords: reasoning algebraic, function limit, generalized patterns

Abstract

The purpose of this study was to investigate the critical role of equilibration in organizing and building students' cognitive structure in the practice of learning mathematics. This qualitative research was designed using a phenomenological study approach. Participants in this study were 30 high school students of XI level. The main research instrument was the interview guide format and the document of cognitive test questions with the circle equation material. Research data obtained were tested for the validity of the data by triangulation. Method triangulation was done by comparing student work data and interview data. Theory triangulation is done by comparing the descriptions of the data obtained with the relevant theoretical sources. The results showed that in the context of knowledge construction (cognitive structure), there is a strong relationship between the process of assimilation and accommodation with equilibration. The role of balance in forming cognitive structures is to guide students to organize previous knowledge (schemas) and new knowledge and create thinking structures to become more complex by considering the socio-cultural dimension (environment) in mathematics learning. Further studies suggest that when selecting topics for equilibration-based activities, teachers should provide an effective learning environment to support the formation of cognitive structures to become more prosperous and complex.

Abstract

The research aims to analyze the gap between teachers' and students' understanding of language literacy and mathematical symbols. The study was designed with a concurrent triangulation strategy. The research respondents consisted of 20 teachers and 120 class VII students. Data collection through questionnaires, interviews, and cognitive tests. Qualitative data was analyzed descriptively, and quantitative data was analyzed inferentially. The results of the analysis of quantitative data show that there is a linear (significant) relationship between understanding language and mathematical symbols and mathematical literacy skills. The results of the qualitative data analysis describe that the teacher's understanding of language and mathematical symbols (high criterion) does not necessarily support the students' understanding of language and mathematical symbols. We confirm the suspicion that there is a gap in the ability of teachers and students to understand language and mathematical symbols. Students need to improve their understanding of mathematical language and symbols. The pattern of errors is based on the teacher's conception of learning in the previous class, so the process of transitioning the teacher's knowledge to students' understanding of mathematics experiences obstacles. The implication is that the process of transitioning meaning from mathematical symbols to written and spoken language must be carried out when the teacher introduces or teaches new topics to students, and the context in which mathematical symbols are used must be followed by clarification.

Abstract. The aim of this research is to examine the effectiveness of a project-based learning model assisted by educational teaching aids, specifically construction blocks, on students' mathematical creative thinking skills. The research method employed is a pre-experimental design with a one-group pretest-posttest approach. The research instruments consist of observation sheets and student essay tests. Data analysis techniques include individual minimum mastery criteria (MMC) achievement tests, classical completeness tests, pretest-posttest mean difference tests, and N-gain tests. The individual MMC hypothesis test, using a one-sample t-test, yielded a significant value (2-tailed) of 0.000 < 0.05, indicating that after the project-based learning intervention with construction block educational aids, the MMC exceeded 70. The classical completeness test, utilizing Z statistics, resulted in Z_calculated = 3.560545 ≥ Z_table = 0.6736, demonstrating that the proportion of students meeting the minimum mastery criteria exceeded 75%. Furthermore, the mean difference test showed that students' mathematical creative thinking skills increased from 36.82 to 85.15. Additionally, the N-gain test yielded a score of 0.7675, with a percentage of 76.74%, categorizing it as high and effective. Therefore, project-based learning assisted by educational teaching aids, specifically construction blocks, is effective in enhancing students' mathematical creative thinking skills.

Abstract

Abstract. In the context of 21st-century education challenges, literacy and numeracy remain foundational competencies for high school students, yet global assessments consistently reveal significant gaps in these skills. This systematic review aims to identify and analyze evidence-based strategies for improving literacy and numeracy among senior high school students. The review synthesizes findings from 15 empirical studies published between 2019-2024 sourced from Scopus, ERIC, and Google Scholar using keywords such as 'literacy numeracy improvement,' 'senior school students,' and 'educational strategies.' Data were analyzed using a thematic analysis approach of qualitative and quantitative studies. The findings highlight four effective approaches: (1) technology-enhanced learning (adaptive platforms), (2) contextualized pedagogy (such as project-based learning), (3) targeted teacher training, and (4) cross-curricular integration. These four strategies were shown to provide measurable improvements to student learning outcomes. The study concludes that a multifaceted, evidence-driven approach, combining these strategies with multidisciplinary collaboration is essential for meaningful and sustainable progress in addressing literacy-numeracy deficits, particularly when adapted to local educational contexts.Keywords: Literacy, numeracy, senior high school students

Abstract

Penelitian ini bertujuan untuk menganalisis keterampilan kolaborasi siswa kategori sedang dalam menyelesaikan masalah bangun ruang berbantuan E-LKS berbasis GeoGebra. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan subjek siswa kelas VII SMP Negeri 3 Pabelan. Data dikumpulkan melalui observasi, wawancara semi-terstruktur, dokumentasi, dan analisis hasil pengerjaan E-LKS berbasis GeoGebra. Analisis penelitian berfokus pada empat indikator keterampilan kolaborasi, yaitu komitmen, musyawarah, menghormati pendapat orang lain, dan partisipasi. Hasil penelitian menunjukkan bahwa siswa kategori sedang mampu menunjukkan keterampilan kolaborasi pada tingkat cukup baik, meskipun masih terdapat keterbatasan seperti dominasi siswa tertentu, kurangnya musyawarah yang mendalam, partisipasi yang belum merata, dan keberanian menyampaikan pendapat yang masih rendah. Penggunaan E-LKS berbasis GeoGebra terbukti dapat memfasilitasi kolaborasi, namun perlu dukungan strategi pembelajaran yang lebih menekankan distribusi peran dan motivasi individu.
