Analisis kemampuan komunikasi matematis ditinjau dari kecerdasan linguistik

Abstract

This study aims to describe the mathematical communication skills in Cartesian coordinates among students based on their linguistic intelligence. Conducted in class IX at Rajapolah Islamic Junior High School, the research utilized exploratory methods. Data were collected from class IX students living in Islamic boarding schools, selected based on their proficiency in one, two, or three indicators of mathematical communication skills and their levels of linguistic intelligence (high, medium, low). Five subjects were chosen: one with high linguistic intelligence, two with moderate, and two with low linguistic intelligence. Data collection involved mathematical communication ability tests, linguistic intelligence questionnaires, and interviews. The research instruments included the researchers, the test questions, and the questionnaires. Data analysis involved data reduction, data presentation, and data verification. Results showed that S-3, with high linguistic intelligence, could fully articulate ideas using mathematical terms, present ideas graphically, and create mathematical models. Subjects with moderate linguistic intelligence, S-17 and S-19, showed varying abilities: S-17 could write ideas in their own words, present graphs, and create models but struggled with detailed explanations and conclusions; S-19 could convey ideas in writing and graphs but had difficulty with modeling. Subjects with low linguistic intelligence, S-29 and S-6, exhibited more challenges: S-29 could write ideas and make graphs but lacked completeness and struggled with modeling everyday events mathematically; S-6 could write ideas in their own words but had difficulties with graphs and modeling.
