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

This research aims to describe the mathematical creative thinking abilities of students in terms of high, moderate, and low levels of intrapersonal intelligence. The study utilizes a descriptive qualitative method. Data collection techniques include mathematical creative thinking ability tests, intrapersonal intelligence questionnaires, and unstructured interviews. The main instruments used in the study are the mathematical creative thinking ability test and the intrapersonal intelligence questionnaire. Data analysis techniques include data reduction, data presentation, and conclusion drawing. Based on the research findings, it was found that students with high intrapersonal intelligence have high mathematical creative thinking abilities, reflected in fluency, flexibility, originality, and elaboration. They are able to overcome obstacles through deep thinking strategies, interest in challenges, and a positive level of self-confidence. Students with moderate intrapersonal intelligence also demonstrate high creative abilities, including fluency, flexibility, originality, and elaboration. They can express ideas visually and generate innovative solutions. Students with low intrapersonal intelligence show potential in fluency and originality; they can demonstrate originality through efforts that are original in nature, such as combining two different plane figures in one solution. However, they have limitations in flexibility and elaboration. Support is needed to develop flexibility and elaboration in mathematical creative thinking abilities.

Abstract

This research was conducted in response to the learning obstacles identified in teaching the system of linear equations with three variables, based on the preliminary study results at SMK Negeri 1 Padaherang. This study utilized a qualitative approach with Didactical Design Research design. Findings from the study indicated that students still faced difficulties in understanding concepts, prerequisite materials, constructing mathematical models, and employing elimination and substitution methods within the subject matter. To address these issues, the researcher developed a learning trajectory with the aim of enhancing the quality of instruction. Identification of learning obstacles served as the basis for designing a Hypothetical Learning Trajectory (HLT) for the system of linear equations with three variables at the vocational school.
