Abstract

Elementary mathematics education necessitates new instructional strategies that can address the varied baseline competencies and backgrounds of kids. The Eliciting Activities Model is a strategy that prioritizes student-centered discovery to enhance learning outcomes. This study seeks to examine the use of the Eliciting Activities Model on mathematics learning outcomes, focusing specifically on students' beginning mathematical competencies and their educational backgrounds. This quantitative study was carried out in three elementary institutions: SDN Batujajar 3, SDN Sukamaju, and SDS Yayasan Beribu, encompassing a total of 81 pupils. The research utilized a survey methodology and applied Two-Way ANOVA to investigate the impact of school origin and beginning mathematical proficiency, along with their interaction, on mathematics learning outcomes. The data gathering process included pre-tests to evaluate students' basic mathematical competencies and post-tests to measure learning results following the implementation of the model. The findings indicated substantial disparities in mathematics learning outcomes contingent upon school origin and pupils' beginning competencies. A notable interaction effect was observed, wherein students with high beginning ability from SDS Yayasan Beribu attained superior learning outcomes relative to students from SDN Batujajar 3 and SDN Sukamaju. The findings indicate that the Eliciting Activities Model effectively improves mathematics learning outcomes, especially when tailored to students' beginning skills and the educational environment.

Abstract

Literacy skills are one of the mathematical abilities that all students need to have in today's global era. However, not all students in border schools have good mathematical literacy skills. This type of research is descriptive qualitative which aims to get an overview of the mathematical literacy skills of students in border areas in solving Minimum Competency Assessment-based problems and also identify factors that influence these skills. This study involved all 57 seventh grade students in the first semester of SPMN Lorontuan Atambua - NTT. The test questions were four numbers in the form of true and false, multiple correct answers and short form. The results of the analysis found that some of them could not read fluently; not all students had a good understanding of basic mathematical concepts; lack of learning experience of contextual problems or story problems that caused them to have difficulty understanding the problem, choosing the mathematical concept used to answer the problem and could not analyze the information provided. The reconstruction that we provide is the need to build a strong mathematical understanding by designing mathematics learning that integrates local wisdom and technology and provides them with varied learning experiences on story problems.         Keywords: math skills, literacy, schools at the border. DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp728-751

Abstract

This research aims to analyze and study in depth about the self-confidence-influenced skills of matematiS from middle school students. The methods in this study use correlational methods with quantitative approaches. The population in this study was junior high school students in west Bandung regency and the sample of 30 people was determined by purposive sampling technique at one of the junior high schools in West Bandung Regency. Instruments in this ability in the form of comprehension ability tests as many as 5 points of questions and self-confidence scale students as many as 24 statement scales. The results of this study concluded that there is a positive influence between self-confidence and the mathematical understanding ability of middle school students. This shows that the higher the student's confidence, the higher the student's mathematical comprehension ability. Factors that affect high self-confidence include: (1) students with a high confidence attitude do not hesitate in making decisions in solving problems (2) students can have many ideas in working on the problem at hand. Meanwhile, students with less confidence will tend to have difficulty in answering potluck questions, students only memorize not yet to understand the understanding of the concept so that the student does not dare to make decisions when solving existing problems.Kata kunci: self confidence, mathematical understanding.

Abstract

This descriptive research aims to analyze the errors of students in completing integer operations in fifth grade students at SD Negeri 2 Cisandawut Sindangkerta District, West Bandung Regency. The subjects in this study were all fifth grade students of SD Negeri 2 Cisandawut with a total of 36 people. Data collection methods used in this study were tests, interviews and documentation. Data analysis techniques in this study used quantitative descriptive analysis and qualitative descriptive analysis. Based on the results of data analysis and discussion, fifth grade students at SD Negeri 2 Cisandawut have low ability to understand integer operation material. This is indicated by the average percentage of achievement of all students which is only 12% with a very low category. The indicator of the problem with the lowest percentage of achievement is performing mixed integer operations. From the results of working on questions 1, 2, 3, 4, or question 5, the type of process skill error is the biggest type of error made by the subject even though the numbers are different. Process skill errors made by the subjects in working on questions 1, 2, 3, 4 and 5 tend to have the same type of error that is the subject is not able to do because they do not know the procedures or steps that will be used to solve the problem correctly

Abstract

This study sought to ascertain whether students' comprehension of mathematical topics had increased as a result of using Discovery Learning with GeoGebra. This study employed a mixed model with a convergent parallel design. 58 eighth-graders from SMP Negeri 5 Purwakarta served as the subjects. Two groups of students were created: an experimental group and a control group. Pretests, posttests, and student response surveys were used to gather data. The Mann-Whitney test, normality, and N-Gain were used to assess the data. According to the data, both groups improved in the moderate category; nevertheless, the experimental class's average N-Gain (0.51) was higher than the control class's (0.38). The Mann-Whitney test findings showed a significant difference (sig. 0.004 < 0.05). Thus, the GeoGebra-assisted discovery learning model enhances conceptual mathematical knowledge more effectively than conventional learning. Furthermore, learning that encourages active participation in discovering ideas is well-received by students.

Abstract

Indonesian students’ mathematical literacy skills, particularly in algebra, are still relatively low, as shown by the results of PISA 2022. A significant contributing factor is the limited relevance of teaching materials to students’ real-life contexts. This study introduces an innovative approach by developing algebra teaching materials based on local wisdom—referred to as local wisdom literacy—as a meaningful context for improving mathematical literacy among seventh-grade junior high school students. The novelty of this study lies in the integration of traditional Timorese cultural practices, such as weaving patterns, local measurement systems, and indigenous numerical reasoning, into formal algebra instruction. Using the ADDIE development model, this Research and Development (R&D) study produced culturally embedded materials that were validated by experts, with validity scores of 85.4% for content and 85% for assessment instruments. The materials were also considered highly practical (96.93% by students, 96% by teachers) and effective, as indicated by a moderate average N-Gain of 0.42 in student learning outcomes. In addition to improving conceptual understanding and mathematical literacy, the developed materials serve as a culturally responsive pedagogical model that is in line with the objectives of the Merdeka Curriculum and supports the preservation of local culture. This study provides a contextual and humanistic alternative in algebra learning, which offers pedagogical value and cultural significance
