Abstract

Numerical skills and problem-solving are crucial competencies influenced by students' cognitive styles. This qualitative descriptive study aims to describe the numerical abilities of eighth-grade students of MTS NU Miftahul Huda Prigen in solving problems of the System of Linear Equations in Two Variables reviewed from the cognitive styles of Field Dependent (FD) and Field Independent (FI). Numerical abilities are measured through indicators of counting, logical thinking, organizing information, and identifying patterns, while the problem-solving process is guided by Polya's steps (understanding, planning, implementing, and re-checking). The research subjects were determined using the Group Embedded Figures Test (GEFT). Data were collected through numerical ability test instruments and interviews, then analyzed descriptively. The results of the study show significant differences between the two types of cognitive styles. Students with the FI cognitive style tend to be more independent, analytical, and organized in processing numerical data and are able to separate relevant information from the problem context. In contrast, FD students tend to need additional guidance, have difficulty in separating important information from complex contexts, and rely heavily on previously given example problems. This conclusion highlights the importance of an adaptive teaching approach to students' thinking characteristics in mathematics learning.

Abstract

Integrating digital technology into elementary math education presents both opportunities and challenges, particularly in assessing students' mathematical communication skills. This study applies the Technological Pedagogical Content Knowledge (TPACK) framework to develop digital assessments for elementary students, focusing on varying self-confidence levels. Utilizing platforms like online portfolios and interactive simulations, the research evaluates students' abilities to communicate mathematical ideas through writing, visuals, and expressions. A mixed-methods approach combined quantitative data from self-confidence questionnaires and digital scores with qualitative data from digital portfolios and interviews. Fifth-grade students from the Assyfa Learning Center Pasuruan Foundation were grouped by self-confidence levels. Findings indicate a positive correlation between self-confidence and mathematical communication skills: students with high self-confidence met all indicators, while those with moderate and low self-confidence met fewer. Digital assessment tools enhanced evaluations and data richness. This study underscores the importance of integrating technology, pedagogy, and content knowledge in digital assessments and recommends ongoing teacher training and child-friendly platforms to boost equitable math assessment.

Abstract

This study aims to investigate career readiness towards understanding the integration of Islamic values and mathematics in prospective mathematics teacher students who are studying at Islamic tertiary institutions. This study involved 375 students consisting of 71 males (19%) and 304 females (81%). Data collection tool by providing an online questionnaire with Google Form related to demographics (place of education, age, and gender), a questionnaire about the integration of Islamic values with mathematics and a career readiness questionnaire for prospective mathematics teachers. Data analysis using part analysis with SPSS. The results showed that there was no direct influence between understanding the integration of Islamic values and mathematics on the competence and career readiness of future mathematics teachers at Islamic tertiary institutions. Students tend to find it difficult to say that between religion and mathematics teachers who are most responsible for teaching mathematics with Islamic values. They are not sure of the competence they have to relate the content of Islamic values to mathematics. In the realm of professional competence, students feel confused about how to start teaching the relationship between Islamic values and learning mathematics in class and when the application is taught.
