Abstract

This research describes the knowledge and beliefs of pre-service teachers about mathematics. Data collection of this research using written test of 143 mathematics pre-service teachers who have taken six semesters at Universitas PGRI Semarang, and interviewing of three pre-service teachers who are not consistent between knowledge and belief. The data are presented in the form of descriptive quantitative and analyzed qualitatively, including data reduction, data display, and conclusions drawing/verification. The results show that most of the knowledge of pre-service teachers are consistent with their beliefs. It is indicated that pre-service teachers’ knowledge has been internalized into a strong belief that affect their words and behaviors. The belief of almost half of pre-service teachers who become respondents changes because of lecturer activity effect. It can say that belief changes at any time, both the process of alteration and the formation of new beliefs as well as the reinforcement of the beliefs they have.

Abstract

social, cultural, and economic challenges faced by local communities(Yulianti, 2020); (Ali et al., 2024; Dewanto et al., 2023; Ichsan et al., 2023). This study examines ethnic involvement in community-based education by highlighting the power dynamics and ethical considerations that underlie the learning process and community empowerment. In the context of pluralistic community education, the involvement of ethnic groups is not only about participation, but also concerns bargaining positions, socio-cultural representation, and the challenges of maintaining justice and inclusivity. Through a qualitative approach based on literature studies and selected case studies, this study found that power inequality between education facilitators and local communities can hinder the process of social transformation. In addition, disregard for local values and norms often triggers resistance or misinterpretation of educational goals. Therefore, it is important to design a community-based educational approach that is sensitive to social dynamics, upholds participatory ethical principles, and strengthens community voices in decision-making. These findings recommend strengthening critical pedagogical practices that integrate local values with the goal of continuing education development.

Abstract

Since mathematics is an abstract discipline, it is necessary to understand context when learning. This pilot study at SDN 1 Kentungan, a "STEM Village" in Joho Village, Yogyakarta, aims to determine the impact of stick-board teaching aids on second-grade students' mathematics learning results in number patterns. The devices used for collecting data include pre-tests and post-tests, interview sheets, observation sheets, and other methods. Meanwhile, the small set of test participants consisted of two SD N 1 Kentungan class II students who attended the STEM Village in Kampung, Joho. The conclusions of this descriptive study show the following: (1) the way teaching tools are used affects how number patterns are taught to primary school pupils; when instructional aids are utilized to assist students in learning a subject more easily and contextually, they are guided by more than just formulas. (2) Students perform better on their pretest and posttest. (3) Students' understanding improves after using visual aids compared to before using them. (4) Students become more curious and engaged in the learning process. The results of the study suggest that class II students at SDN 1 Kentungan benefit from using instructional aids, which are regarded as compelling and well-done.

Abstract

To improve the skills required for students in the 21st century, such as basic skills, competencies, and character, mathematical literacy is one of the critical factors. With the application of STEM, students are expected to be able to think critically so that they can improve their mathematical literacy skills. This research used a descriptive qualitative method with subjects aged 3–9 years in Joho Village, D.I. Yogyakarta, Indonesia. In this study, data was collected using three methods: observation, interview, and documentation. The instruments used include a critical thinking scale, an observation guide, and an interview guide. The results obtained from this study indicate that applying STEM can hone students' critical thinking skills. Two classifications were obtained by applying STEM, namely groups with high and average levels of critical thinking. Students can identify given problems, formulate the core of the problem, provide solutions based on a problem, draw conclusions, and evaluate relevant arguments for solving a problem. Thus, research is expected to provide a strong foundation for applying STEM-based learning to enrich students' mathematical learning experiences and prepare them for future challenges in the age of globalization towards Indonesia in 2045.

Abstract

This research aims to develop an Android-based learning media application using MIT App Inventor to enhance students' mathematical critical thinking skills. The study employs a Research and Development (R&D) approach with the design thinking method, consisting of five stages: empathize, define, ideate, prototype, and test. During the empathize phase, in-depth interviews were conducted with five personas to identify existing issues, which were then summarized into an empathy map. In the define stage, data were analyzed using the How Might We technique to frame actionable problems. The ideate stage involved brainstorming solutions through mind mapping, followed by prototyping the application design based on the identified needs. In the testing phase, the application was evaluated for effectiveness (measured by success rate), efficiency (time-based metrics), and user satisfaction (via the System Usability Scale). Data were collected through questionnaires to assess the application’s viability, efficiency, and alignment with user needs. After completing the design thinking process, a critical thinking competency test was administered to compare learning outcomes on three-variable linear equations before and after using the media. Post-intervention results revealed above-average scores, demonstrating the application’s positive impact on students' mathematical critical thinking abilities. This study contributes to innovative learning media development in mathematics education, offering a simple, interactive, and accessible tool adaptable to individual learning needs.

Abstract

Students are required to think critically when solving math problems related to everyday life. However, many still do not pay enough attention to the importance of critical thinking skills in the education system, and teachers tend to guide students to solve problems correctly rather than express ideas or notions. The purpose of this research is to assess and describe students’ critical thinking skills in solving story problems involving linear equations, reviewed from the student’s initial abilities. The method used in this research is descriptive qualitative. The purposive sampling and snowball sampling techniques were used as methods for subject selection in this study. The research subjects consist of 6 seventh-grade students from SMP Negeri 3 Randudongkal selected based on specific criteria, where students had initial ability scores of 80-90, good communication, and were recommended by the teaching teacher. The triangulation used in this research is source triangulation. Written tests and in-depth interviews were used as data collection techniques in this study. The data analysis stage used was reducing data, presenting data, and deriving a conclusion. The analysis results obtained from the written critical thinking skills test and interviews in the research show a conclusion that students with high initial abilities can apply four out of six FRISCO critical thinking skill indicators, namely the indicators of Focus, Reason, Inference, and Clarity in solving story problems involving one-variable linear equations. However, they require a greater understanding and precision to apply the indicator of Situation and Overview. Most students failed to explain their knowledge during the interview, indicating a gap between their written and verbal critical thinking skills. This research can serve as a reference for further studies related to critical thinking skills and help teachers design lessons that pay more attention to the critical thinking abilities of students.
