Abstract

This study investigated the effect of numeracy skills on mathematics learning outcomes, specifically in the area of 2 plane figures, among 61 fifth-grade students in Labuan Regency. Using a quantitative correlational design, descriptive results showed that students' numeracy skills were in the good category (average 75.90) and learning outcomes were in the fair category (average 70.33). The Spearman rank correlation test showed a positive and significant effect, but the relationship was weak (r = 0.292; p = 0.023 < 0.05). These findings confirm that better numeracy skills contribute to higher learning outcomes, but the weak correlation underscores the important role of other factors (e.g., teaching methods, motivation). This study implies that teachers should optimize contextual numeracy-based learning to improve achievement, especially for complex concepts such as the area of a trapezoid.

Abstract

Karies gigi merupakan salah satu penyakit terbanyak pada anak-anak di seluruh dunia. Pada rentang usia 3-6 tahun, sembilan dari sepuluh anak di Indonesia mengalami karies gigi. Silver diamine fluoride (SDF) merupakan salah satu pilihan dalam manajemen karies untuk menghambat aktivitas karies pada gigi sulung. Akhir-akhir ini SDF telah mendapatkan banyak perhatian karena kemudahan aplikasinya, efektivitas, harga yang terjangkau, dan waktu kerja yang singkat. Artikel ini bertujuan mengulas tentang perawatan silver diamine fluoride pada praktik kedokteran gigi anak.

Abstract

The growing demand for twenty-first century competencies has increased the need for mathematics instruction that promotes conceptual understanding, reflective reasoning, and active student engagement. However, trigonometry learning in many secondary schools remains dominated by procedural instruction and formula memorization, causing students to experience difficulties in understanding conceptual relationships. This study aimed to investigate the implementation of the discovery learning model in improving students’ conceptual understanding of trigonometry among class XI students at SMA IT Persis Palu, Indonesia. The study employed a qualitative-dominant Classroom Action Research design conducted through two iterative cycles consisting of planning, action, observation, and reflection stages. The participants involved 23 students, with three focal informants selected purposively based on preliminary conceptual difficulties. Data were collected through conceptual understanding tests, classroom observations, interviews, field notes, and documentation. The findings revealed substantial improvement in students’ conceptual understanding across all indicators, including the ability to restate concepts, identify conceptual relationships, distinguish examples and non-examples, and apply trigonometric concepts accurately in contextual problem-solving situations. Learning mastery increased progressively until 88.24% of students achieved the minimum competency criterion in Cycle II. The study concludes that discovery learning effectively facilitates conceptual reconstruction, collaborative inquiry, and meaningful mathematical understanding in secondary trigonometry learning.

Abstract

Students still experience difficulties in solving story problems on the topic of equivalent comparisons, so a study is needed regarding problem-solving profiles based on logical-mathematical intelligence. This study aims to describe the problem-solving profiles of equivalent comparisons viewed from the logical-mathematical intelligence of eighth-grade students at SMPN 19 Palu. The study used a descriptive qualitative approach. The subjects of the study consisted of two students who were selected purposively based on the results of Olivia's (2009) logical-mathematical intelligence questionnaire, namely one student in the high category (AST) and one student in the low category (PTR). Data were collected through problem-solving tests and in-depth interviews, then analyzed using an interactive model that includes data condensation, data presentation, and conclusion drawing. The results showed that AST was able to carry out all stages of problem-solving according to Polya completely and obtained correct answers (12 liters). In contrast, PTR was only able to fulfill the stage of understanding the problem, while at the stages of formulating plans, implementing solutions, and re-checking, they still experienced conceptual errors resulting in incorrect answers (5.333 liters). These findings indicate that students with high logical-mathematical intelligence have a more systematic and accurate problem-solving profile than students with low logical-mathematical intelligence.

Abstract

Critical thinking is an important competency in mathematics learning, but many students still experience difficulties in solving problems, especially on the Pythagorean theorem. This study aims to describe the critical thinking profile of eighth-grade students at SMP Negeri 7 Palu in solving Pythagorean theorem problems in terms of mathematical ability. The study used a descriptive qualitative approach with two subjects, namely one student with high mathematical ability (IR) and one student with medium mathematical ability (MN), who were selected purposively based on the results of a mathematical ability test. Data were collected through a mathematical ability test, a Pythagorean theorem problem-solving test, and in-depth interviews to reveal students' thinking processes. Data analysis was carried out through the stages of data reduction, data presentation, and drawing conclusions by referring to the six FRISCO critical thinking indicators according to Ennis, namely focus, reason, inference, situation, clarity, and overview. The results showed that students with high mathematical ability were able to optimally fulfill all FRISCO indicators, while students with medium ability only fulfilled some of the indicators and tended to rely on one solution procedure. These findings indicate that mathematical ability influences the quality of students' critical thinking, so that learning that encourages the use of various problem-solving strategies is needed to develop critical thinking skills more optimally.
