Abstract

Corn is an alternative source of carbohydrates besides rice and wheat. Corn is used as feed in the livestock industry and various processed foods. BPS data for 2023 shows that corn production is decreasing, which has an impact on corn self-sufficiency and a lack of corn fulfillment for export needs. The research aims to determine the effect of interactions between soil processing systems and weed control on the growth and yield of hybrid corn plants. This research uses factorial RAK with interactions. The first factor is the tillage system with levels T0 (no tillage) and T1 (tillage). The second factor is weed control time with levels G0 (weed free), G1 (weeds controlled at 15 HST), G2 (weeds controlled at 35 HST), G3 (weeds controlled at 55 HST). The results showed that the tillage system and weed control time were significantly different in the test BNT 5%. However, the interaction not significantly different in the test BNT 5%. Corn plants with tillage (T1) and weed free (G0) showed the best growth and yield compared to other treatments in all observed variables.

Abstract

This study explores the procedural skills of grade VIII students in solving Pythagorean Theorem problems, focusing on the diversity of problem-solving steps and error patterns that emerge. A descriptive qualitative method was used in this study, with three students selected as subjects based on high, medium, and low levels of mathematical ability. Data were collected through problem-solving tasks and semi-structured interviews to comprehensively understand the students' approaches and strategies. The results showed that students with high procedural skills implemented problem-solving steps in a structured manner, while those with moderate skills often needed to be more consistent in recording critical steps. Students with low skills tended to bypass procedural structures and proceed directly to solutions, leading to a higher rate of errors. Error patterns varied by students' mathematical ability levels: high-ability students made no errors, medium-ability students exhibited errors in illustrations and procedural consistency, and low-ability students struggled with writing expressions and fully implementing steps. These findings emphasize the need for instructional approaches tailored to students' skill levels, such as structured learning and scaffolding, to strengthen procedural skills. A follow-up study with a broader sample is recommended to validate these findings and assess the effectiveness of instructional strategies for enhancing students' procedural skills across various mathematical topics.

Abstract

This study aims to explain students' mathematical processes in solving open-ended problems using a popular context from TikTok, specifically involving the calculation of the size of legit layer cake pieces as presented by the TikTok user Ci Mehong. Descriptive qualitative method is the research paradigm used to explain the mathematical process. The subjects were 81 eleventh-grade students who were instructed to take the test. Data collection was carried out by giving tests and diagnostic interviews conducted at the same time when students answered the questions, then the data were analyzed using a combination of thematic analysis techniques and flow models based on mathematical modeling indicators. The results showed numerical, graphical, algebraic, and verbal representation forms in the real situation-real world model process. In the real world model-mathematical modeling process, students demonstrated the use of diverse mathematical concepts, including cuboid volume, geometric sequences, exponents, and arithmetic operations. While in the mathematical modeling-mathematical result process, students derived results in volume and length units, which were then contextualized back to the real-world situation by making assumptions about the number of cake pieces per person.

Abstract

This study explores junior high school students’ mathematical problem-solving abilities in the topic of linear equations based on their cognitive styles. A qualitative case study design was employed involving 13 ninth-grade students from SMP Negeri 6 Watubangga, Southeast Sulawesi, Indonesia. Students’ cognitive styles were identified using the Matching Familiar Figures Test (MFFT), resulting in the classification of nine impulsive and four reflective students. Four participants, consisting of two impulsive and two reflective students with moderate mathematical ability, were purposively selected for in-depth analysis. Data were collected through a mathematical problem-solving test on linear equations, semi-structured interviews, and documentation. Data analysis followed the interactive model of Miles, Huberman, and Saldaña, including data condensation, data display, and conclusion drawing and verification. Students’ problem-solving performance was analyzed using Polya’s four-stage framework: understanding the problem, devising a plan, carrying out the plan, and looking back. The findings revealed clear differences between impulsive and reflective students across the problem-solving stages. Impulsive students tended to respond quickly but often failed to identify relevant information, develop systematic solution plans, and verify their answers, resulting in procedural and computational errors. In contrast, reflective students demonstrated more organized and systematic problem-solving processes, carefully selecting strategies and reviewing their work before reaching conclusions. These findings highlight the importance of considering cognitive styles when designing adaptive mathematics instruction to enhance students’ problem-solving abilities.

Abstract

This study investigated the characteristics of seventh-grade students’ mathematical conceptual understanding of Social Arithmetic and identified the factors influencing that understanding. The study employed a qualitative descriptive approach involving 18 seventh-grade students from SMPN 6 Watubangga. Three students were subsequently selected as key informants through purposive sampling based on variations in their problem-solving strategies, conceptual understanding, and communication abilities. Data were collected through problem-solving tasks and structured interviews and were analyzed using the interactive model of data condensation, data display, and conclusion drawing and verification. The findings revealed that students demonstrated varying levels of mathematical conceptual understanding, which were generally characterized by partial mastery of concepts and difficulties in applying concepts consistently across different problem situations. While some students were able to identify relevant information and recognize fundamental concepts such as percentages and discounts, they frequently encountered computational errors and difficulties in communicating mathematical reasoning. Other students struggled to connect multiple Social Arithmetic concepts, determine appropriate solution strategies, and solve contextual problems requiring multistep reasoning. The factors influencing students’ conceptual understanding included limited mastery of fundamental concepts, difficulties in connecting related concepts, insufficient procedural accuracy, and limited mathematical communication skills.

Abstract

Various instructional models have been developed to improve students' mathematical literacy; however, empirical evidence regarding their characteristics and effectiveness remains fragmented across the literature. This study aimed to identify, classify, and synthesize the instructional models used to enhance mathematical literacy among secondary school students. A systematic literature review (SLR) was conducted following the PRISMA 2020 guidelines. The literature search was performed in the Scopus and Education Resources Information Center (ERIC) databases and included peer-reviewed journal articles published between 2017 and 2026. Of the 95 records initially identified, 24 studies met the inclusion criteria and were included in the final synthesis. The findings indicate that the use of contextual, authentic, and culturally relevant problems is the most prominent characteristic of mathematics instruction for developing mathematical literacy. In addition, Problem-Based Learning (PBL), Project-Based Learning (PjBL), STEM/STEAM-based approaches, digital technology integration, and Realistic Mathematics Education (RME) were the instructional models most frequently implemented. Most studies reported improvements in students' mathematical literacy following the implementation of these models, particularly when instruction incorporated problem-solving, mathematical modeling, collaboration, reflection, and meaningful uses of technology. Nevertheless, the available evidence is largely concentrated in the Indonesian context and exhibits considerable methodological diversity. Future research should therefore examine the effectiveness of instructional models across more diverse educational contexts and investigate their long-term impact on the development of students' mathematical literacy.

Abstract

This study aims to explore and analyze the application of a constructivist approach in mathematics learning at SMA Negeri 1 Lalolae. The research employed a descriptive qualitative method with data triangulation through classroom observations, teacher interviews, and student questionnaires. The findings indicate that constructivist elements have been partially implemented, as reflected in classroom discussions, opportunities for students to express arguments, and activities that encourage independent problem solving. Students showed positive responses in terms of increased motivation and learning engagement, although some students remained passive and experienced difficulties in constructing concepts independently. In conclusion, the implementation of a constructivist approach in mathematics learning at SMA Negeri 1 Lalolae has not yet been optimal and requires support in the form of improved learning facilities and teacher training to enhance its effectiveness and sustainability.
