Abstract

The low level of understanding of the concept of circles among vocational school students and the absence of P5/PPRA-based mathematics teaching materials are the basis for this research to develop teaching materials used in the learning process in the form of modules that can be used as learning materials to make them more interesting, varied, and can be studied independently by students outside of class hours. The type of research used in this study was research and development (R&D) with the 4D model (Define, Design, Develop, Disseminate). This research was conducted in class XI of SMK Gajah Mada Mojokerto. The instruments used in this study were interview guidelines, validation sheets, questionnaires, and tests with data collection techniques, namely interviews, written tests, and questionnaires. The data analysis techniques used consisted of validity tests, practicality tests, and effectiveness tests. The validation results show that the e-module meets the validity criteria in terms of language with a percentage of 71.9% and meets the criteria of high validity in terms of material, learning, and IT with percentages of 85.7%, 97.5%, and 97.5%. The results of the practicality test from the questionnaires filled out by teachers yielded a percentage of 86.4%, and from the questionnaires filled out by students, it was 95%, both of which were in the very practical criteria. The results of the effectiveness test obtained from the calculation of pretest and posttest scores with the N-Gain score calculation were 73%, so the e-module is quite effective for use in learning.

Abstract

The purpose of this study is to describe the mental model of students in solving algebraic proof problems reviewed based on their gender. This study is a descriptive study. Data and data sources were obtained through problem-solving questionnaire instruments and subject interviews. The study was conducted at UIN Maulana Malik Ibrahim Malang. The subjects used were one male student and one female student with high GPAs. The validity of the data was tested using time triangulation. Data analysis refers to Miles Huberman's data analysis technique. The results of the study indicate that the mental model of male students in solving algebraic proof problems includes an implicational mental model and a functional mental model, while in terms of structure, the syllogistic decision making that occurs is invalid. While the mental model of female students in solving algebraic proof problems includes an implicational mental model, a functional mental model, and a structural mental model.

Abstract

The development of the 21st century demands that students not only have the ability to think critically and creatively, but also communication skills, especially in mathematics learning. However, various studies show that students still have difficulty communicating their mathematical ideas, both verbally and in writing, especially when working in groups and facing contextual problems. The purpose of this study is to describe the mathematical communication profile of students in solving contextual problems collaboratively reviewed based on high, medium, and low self-efficacy. A qualitative approach with an exploratory research type is used in this study. The subject of the study is a student of class XI MAN 2 Malang. The research data were obtained through the results of the Contextual Problem Solving Task (TPMK) and interviews. Data analysis was carried out by the triangulation method. The results showed that students with high self-efficacy tended to communicate their mathematical ideas orally. Students with self-efficacy showed balanced verbal and written communication but were less consistent in explaining mathematical models and operations, while students with low self-efficacy were more dominant in written communication.

Abstract

Spatial reasoning is an essential ability in learning geometry, particularly in three-dimensional geometry. This ability encompasses visualization, mental rotation, and spatial orientation, which are required to solve three-dimensional geometric problems. Students' spatial reasoning strategies may differ due to the influence of their personality types. Therefore, this study aims to describe the spatial reasoning of eleventh-grade students at MAN 3 Kediri in solving three-dimensional geometry problems based on their personality types. This study employed a qualitative approach with a phenomenological design. The participants were selected purposively based on Carl Gustav Jung's personality type questionnaire and consisted of three extroverted students and three introverted students. Data were collected through written tests and interviews, then analyzed using the Miles and Huberman model. Technique triangulation was employed to ensure the trustworthiness of the data. The findings revealed that extroverted students were more proficient in collaborating, engaging in discussions, and utilizing visual aids to understand geometric transformations. However, they tended to be less accurate in calculations and less systematic in organizing their solution procedures. In contrast, introverted students tended to be more persistent, conducted in-depth independent analyses, and demonstrated well-structured problem-solving strategies. Nevertheless, they experienced difficulties in visualizing three-dimensional objects without the support of concrete illustrations. These findings indicate that personality type influences how students engage in spatial reasoning. Therefore, teachers are expected to adapt their instructional strategies, such as implementing interactive visual discussions for extroverted students and providing independent practice based on visual representations for introverted students, so that both groups can optimize their spatial reasoning abilities in mathematics learning.
