Abstract

The purpose of this study was to determine the improvement of students' mathematical literacy skills through the application of genially on problem-based learning (PBL) model. This research was conducted at SMA Negeri 6 Garut. The research method used was quasi experimental with pretest-posttest control group design. The experimental class was given treatment by applying genially to the problem-based learning (PBL) model while the control class was given the problem-based learning (PBL) model only. The population in this research were all students of class X, with a sample of two classes namely class X 12 as the experimental class and class X 4 as the control class. sampling based on the random assignment technique. The data collection techniques used were observation, unstructured interview, and mathematical literacy test. The instruments used were student mathematical literacy test. The data analysis technique used the Two Independent Samples Test. Based on the results of data analysis, it can be concluded that there is an increase in students' mathematical literacy skills through the application of Genially in the Problem Based Learning (PBL) model with a significance of 0.03.

Abstract

The fishing activities carried out by traditional fishermen involve various mathematical concepts that develop contextually through daily cultural practices. However, these mathematical concepts are often not optimally integrated into formal education, leading to mathematics being viewed as abstract and disconnected from real-life situations. This study aims to describe and analyze the mathematical concepts applied by fishermen in their fishing activities. This study employs a qualitative method with an ethnographic approach. The research participants are fishermen at Pamayangsari Beach, Cipatujah Subdistrict, Tasikmalaya Regency, selected through purposive sampling based on their experience and knowledge in fishing activities. Data were collected through observation, semi-structured interviews, and documentation, with the researcher serving as the primary instrument, supported by interview guidelines, observation checklists, and documentation guidelines. Data analysis utilized the Miles and Huberman interactive model, which includes data reduction, data presentation, and drawing conclusions. The research findings revealed several mathematical activities performed by the fishermen, namely counting, measuring, locating, and explaining. Counting activities were observed in calculating fuel requirements and distributing the catch. Measuring activities were found in measuring sea depth, determining mesh size, boat cargo capacity, and estimating tides. Locating activities were evident in determining the direction and position of nets using natural landmarks, while explaining activities were reflected in the fishermen’s ability to describe the fishing process in a sequential and logical manner. The research findings indicate that mathematical concepts develop contextually within the cultural practices of fishermen and have the potential to support mathematics learning based on local culture.

Abstract

Indonesian students’ mathematics achievement remains low according to the 2022 PISA data, which is believed to be associated with academic procrastination, math anxiety, and self-esteem. This study aims to examine the direct and indirect relationships between math anxiety and self-esteem with academic procrastination and their association with mathematics achievement. The method used was quantitative with a path analysis design. A sample of 309 students from SMAN 1 Manonjaya was selected using simple random sampling. The instruments included the Mathematics Anxiety Scale, the Rosenberg Self-esteem Scale, the Procrastination Assessment Scale for Students, and the final semester summative scores in mathematics. The results showed that simultaneously, mathematics anxiety, self-esteem, and academic procrastination had a significant relationship with mathematics achievement (R²=0.546). However, a counterintuitive relationship was found: mathematical anxiety was negatively associated with procrastination (? = ?0.076), while higher self-esteem was associated with increased procrastination and decreased mathematics achievement (? = ?0.569). Procrastination significantly mediates the relationship between self-esteem and mathematics achievement, but not for math anxiety. These findings suggest that psychological relationships with mathematics achievement are not always linear. Implicitly, interventions should be directed toward directly reducing math anxiety, as well as strengthening self-regulation in students with high self-esteem.Keyword: math anxiety, self-esteem, academic procrastination, academic achievement, path analysis.
