Abstract

In the context of 21st-century mathematics education, the ability to construct andutilise mathematical representations is fundamental to successful problem solving,particularly for future elementary school teachers. However, the role of individualpersonality traits—especially the dichotomy between Thinking and Feeling types, asdefined by the Myers-Briggs Type Indicator (MBTI)—remains underexplored as afactor influencing representational strategies. This study addresses a critical researchgap by examining how these personality types affect the process of mathematicalproblem-solving. Using a qualitative descriptive approach with an intrinsic case studydesign, the research involved two prospective primary school teachers with distinctMBTI profiles. Data were collected through MBTI questionnaires, problem-solvingtasks, and task-based interviews, then analysed using thematic coding aligned withPolya’s problem-solving steps. The findings reveal distinct differences in the types andstructures of representations used: Thinking-type participants favoured symbolic andlogical representations. In contrast, Feeling-type participants relied more on intuitiveand narrative forms. These results highlight the impact of personality on cognitiveprocesses in mathematical reasoning. This paper contributes new insights to theintersection of mathematics education and personality psychology, with implicationsfor differentiated instruction in teacher education programs.

Abstract

This study aims to determine the effect of implementing the Problem-Based Learning (PBL) model, supported by the Bintang Ajaib teaching aids, on student learning outcomes and activities related to sequences and series in 10th grade at SMA NU Genteng Banyuwangi. This study employs a quantitative, quasi-experimental design, specifically a Nonequivalent Pretest-Posttest Control Group Design. The research sample consisted of an experimental class using the PBL model supported by the Bintang Ajaib teaching aids and a control class using conventional instruction. Data collection techniques included observation, documentation, and pretest and posttest assessments. Data analysis utilized the Shapiro-Wilk normality test, homogeneity test, and Independent Samples t-Test using SPSS version 27.0. The results showed a significance value (Sig. 2-tailed) of 0.007 < 0.05, so H₀ was rejected, and H₁ was accepted. The average learning achievement of students in the experimental class was 85.90, higher than that of the control class (79.39). In addition, student activity in the experimental class increased because students were more engaged in discussing, solving problems, and understanding concepts through concrete, engaging teaching aids. Thus, the Problem-Based Learning model, supported by the Bintang Ajaib teaching aid, is an effective alternative to mathematics instruction that improves student learning outcomes and engagement.
