Abstract

Mathematical thinking skills are crucial competencies for civil engineering students in dealing with increasingly complex infrastructure problems, one of the foundations of which is laid by basic calculus. However, students show varying abilities, indicating the influence of internal factors such as personality. This study aims to describe the relationship between students' personality types, as measured by the Myers–Briggs Type Indicator (MBTI) framework, and the mathematical thinking abilities of civil engineering students in calculus learning. This study uses a descriptive qualitative approach involving civil engineering students at Samudra University. Personality types were determined using the MBTI questionnaire, while mathematical thinking skills were measured by analyzing students' written answers to calculus problems compiled based on mathematical thinking indicators. Data were analyzed descriptively and qualitatively to identify patterns in mathematical thinking skills across personality types. The results of the study indicate that students with ESFJ or SFJ tendencies tend to show strength in applying concrete procedures (specializing), while students with ENFJ or NFJ tendencies tend to demonstrate greater flexibility in developing intuitive ideas. This study suggests that students' personalities should be taken into account when designing calculus learning. The application of adaptive and differentiated learning strategies tailored to individual personality characteristics may be considered.

Abstract

Numeracy literacy is an essential competency that should be developed from the elementary school level to help students understand and apply mathematical concepts in daily life. However, elementary school students’ numeracy literacy remains low, especially in understanding problems, connecting numerical information, and solving contextual mathematical tasks. This condition is caused by mathematics learning that is still abstract, procedural, and less connected to students’ real-life experiences. Therefore, contextual and engaging learning media are needed to support numeracy learning. This study aims to develop a Doodle Art comic based on Realistic Mathematics Education (RME) to enhance elementary school students’ numeracy literacy. The study employed a Research and Development (R&D) method using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The research instruments included validation sheets, teacher and student questionnaires, numeracy literacy tests, observations, and interviews. The results showed that the RME-based Doodle Art comic was categorized as highly feasible, with an average validation score of 4.41. Teacher responses obtained an average score of 4.54, categorized as very practical, while student responses obtained an average score of 4.50, categorized as very good. In addition, students’ numeracy literacy scores increased from 61.10 in the pretest to 76.18 in the posttest. The study concludes that the RME-based Doodle Art comic has the potential to become an innovative and contextual learning medium for improving elementary school students’ numeracy literacy.
