Abstract

Critical thinking skills which are learned by students in mathematics instruction will help students solving problems they encountered in daily life. Direct and inverse proportion is a topic in mathematics which provides opportunity for students to think more critically since it is one of the most cognitively challenging topics in the school curriculum. This research is descriptive in nature aims to describe the critical thinking processes of high school students in solving direct and inverse proportions problems. It used test and interview methods to collect the data, while the subjects consisted of two grade 7 students. The research results show that students perform the following critical thinking processes: (1) conducting interpretation by categorizing what are given and asked, and clarifying meaning in detail; (2) analyzing well by examining ideas and identifying arguments as well as reasons; (3) doing inferences by querying evidence, forming hypothesis, and trying to prove the hypothesis and to draw a conclusion; (4) carrying out evaluation by assessing credibility of claims and quality of arguments before jumping to the next steps, (5) doing explanation by stating results, justifying procedures, and present arguments clearly; (6) performing self-regulation by doing monitoring and correcting what they have done.

Abstract

One goal of mathematical learning in an independent curriculum is to communicate ideas with symbols, tables, diagrams, or other media to clarify a situation or problem, and present a situation into a mathematical symbol or model (communication and mathematical representation). Students must have good and clear communication skills. Communication is not only done by question and answer or by discussion between students and other students, communication can also be done by answering math problems. Communication, self-confidence, and mathematics are considered mutually influential. This study is a descriptive study with a qualitative approach aimed at (1) describing students' mathematical communication ability in solving data material numeration problems and the uncertainties reviewed by high self-efficacy (2) to describe students' mathematical communication ability in resolving problems. The results of this study are (1) The mathematical communication ability of students to solve numeration problems with high self-efficacy was stated to be accurate, smooth but incomplete. Meanwhile, students' verbal communication skills in solving numeration problems with high self-efficacy were stated to be accurate, complete and smooth (2) The mathematical communication ability of students to solve numeration problems with low self-efficacy is stated to be inaccurate, incomplete and not smooth, as there are still scribbles and inaccuracies in solving problems. For verbal mathematical communication skills students solve numeration problems with low self-efficacy are also stated to be inaccurate, incomplete, and not smooth. Students can't solve both writing and verbal problems at all.

Abstract

Indonesia's Minister of Education and Culture determined Merdeka Belajar Kampus Merdeka Curriculum) in 2019. Computational thinking is one of the skills that supports curriculum development in science and technology. Bebras tasks can be used to practice computational thinking. The research aims to describe the computational thinking abilities of students with high and medium mathematical and logical intelligence in completing bebras tasks. The research method is qualitative descriptive. Instruments in research are logico-mathematical intelligence tests, mathematical ability tests, computational thinking tasks, and interview guides—data analysis through data condensation, data presentation, and conclusions. The subjects in the research are students in class XI SMA Negeri 4 Kediri, one student with high and medium mathematical logical intelligence. The research results show that students with high logico-mathematical intelligence can answer entirely and in detail because they always give reasons that support indicators of problem decomposition, pattern recognition, algorithmic thinking, abstraction, and generalization. Meanwhile, students with medium logico-mathematical intelligence can answer well but do not complete the problem decomposition indicator and have less understanding of questions, so there are errors in calculations on the pattern recognition indicator. Based on the research results, the researcher hopes educators introduce Bebras tasks in mathematics learning to improve computational thinking.

Abstract

Culture and mathematics have a close relationship and cannot be separated. One way to connect mathematics learning with everyday life is through the concept of ethnomathematics. Ethnomathematics is an important concept for understanding the role of mathematics in everyday life. By using an ethnomathematics approach, mathematics learning can be delivered contextually according to students' daily lives. Cultural involvement in understanding mathematics through ethnomathematics allows learning to be more relevant and meaningful for students. Therefore, this research was conducted to identify ethnomathematics and ethnomodelling activities found in pottery burning activities in Rendeng Village, Malo District, Bojonegoro Regency. This research is qualitative research with an ethnographic approach. The instruments used in this research were interview guidelines and observation sheets. The subjects in this research were pottery craftsmen in Rendeng Village. Next, the data will be analyzed by condensing data, presenting data, and drawing conclusions. The results of the research show that there are ethnomathematics activities in the pottery firing process, namely counting activities, location determining activities, measuring activities, designing activities, playing activities and explaining activities. There is also ethnomodeling in how to calculate combinations of pottery that can be fired simultaneously to achieve optimal results. The results of this approach are calculations using the simplex method which can be used by teachers as learning material in schools as well as calculations using Excel Solver which can be used by pottery craftsmen in Rendeng Village as a reference for determining the right combination of pottery to achieve optimal results in the pottery firing process. . Thus, the pottery burning activity in Rendeng Village can be a bridge for teachers to teach mathematical concepts at school. The hope is that through this activity, students can more easily understand the mathematical concepts taught in class.

Abstract

Algebraic reasoning is the process of finding patterns from mathematical problems, recognizing relationships between quantities, and forming generalizations. Algebraic reasoning is important to develop to build deeper and more complex mathematical conceptual development. One step that can be taken is by giving open-ended questions. Adversity quotient (AQ) influences students in responding to problems. This research is a qualitative descriptive study which aims to describe the algebraic reasoning of students with climber, camper and quitter AQ types in solving open-ended problems. The instrument for determining research subjects is the Adveristy Response Profile (ARP) questionnaire, while the instruments for collecting data are algebraic reasoning tasks and interview guides. Data analysis is carried out through data condensation, data presentation, and drawing conclusions. The subjects in this research were class VIII students at SMPN 3 Surabaya consisting of one student from each type of AQ climber, camper, and quitter. The results of the research show that in the pattern search indicator, climber and camper students collect existing information and find pattern regularities. Quitter students make calculation errors so they do not find pattern regularity. In the pattern recognition indicator, climber and camper students tested the truth of the patterns they had previously obtained, while quitter students did not carry out a truth test because in the previous activity they did not find pattern. In the generalization indicator, climber and camper students make general rules in precise mathematical form. Quitter students do not write general rules on answer sheets and cannot provide explanations during interviews.

Abstract

Mathematical abstraction is essential in constructing mathematical concepts, particularly in proof. The RBC+C epistemic actions—recognizing, building-with, constructing, and consolidating—are key cognitive processes in proof construction. However, the impact of mathematical reading and writing abilities on these processes remains unexplored. This study investigates how students’ mathematical reading and writing abilities affect their epistemic actions when proving the congruence of two triangles. This qualitative research adopts a case study design involving three undergraduate students who have completed a geometry course. The participants were selected based on their reading and writing proficiency levels: high, moderate, and low. Data were collected through reading and writing assessments, proof-solving tasks, and semi-structured interviews. The analysis follows the RBC+C framework to identify patterns in students’ cognitive process during proof construction. Findings reveal that students with high mathematical reading and writing abilities demonstrate a more structured proof strategy, effectively recognizing key properties, building logical connections, and constructing valid arguments. High-proficiency students also exhibit flexibility in using both geometric and algebraic approaches in proving. In contrast, students with lower reading and writing abilities struggle with symbolic representation, logical coherence, and notation consistency, leading to incomplete or incorrect proofs. Moreover, consolidation of mathematical ideas, such as reusing known theorems and revisiting proof steps, occurs more frequently in high-achieving students, enabling deeper conceptual understanding. This study highlights the critical role of mathematical literacy in the proof process. It suggests that strengthening reading and writing instruction in mathematics education can enhance students’ ability to construct rigorous proofs. The findings contribute to the development of instructional strategies that integrate mathematical literacy into proof-based learning, ultimately fostering students’ reasoning and problem-solving skills in mathematics.

Abstract

Students frequently receive grades that fall short of the school's Minimum Mastery Criteria, particularly in the algebra chapter, specifically the topic of evaluating algebraic expressions. This occurs as a result of pupils' lack of understanding of variables and how to substitute variable values in algebraic forms. As a result, many students make mistakes when changing variable values, and their learning objectives are seen to be unfinished. The aim of this study was to determine whether using a differentiated learning model with the Teaching at the Right Level approach and algebraic block teaching aids improved the learning outcomes of class VIII students at SMP Negeri 25 Surabaya on the content on the value of algebraic forms. Using the Kemmis & McTaggart approach, this study is an example of classroom action research. The study's findings indicate that students are learning more about the importance of algebraic forms. The pre-cycle, cycle I, and cycle II learning completion rates for students were 14.7%, 64.7%, and 88.2%, respectively. This demonstrates how using a customized learning model in conjunction with algebraic block teaching aids and the Teaching at the Right Level strategy can enhance student learning outcomes.
