Abstract

This research aims to evaluate a selected element of mathematical knowledge intended for teaching in Indonesian schools, namely the concept of sets. The evaluation assesses whether the information conveyed the criteria of knowledge that is Justified, True, and Believed (JTB). This research follows a qualitative approach with a case study design. The research involves 250 students and nine teachers from two different schools. The collected data was analyzed using the Constant Comparative Method (CCM) as the data analysis model. The study's findings reveal that beliefs with truth value only relate to interpreting sets as a well-defined collection of objects. However, teachers and students cannot prove their beliefs and cannot interpret well-defined as an individual's ability to determine a property P. Thus, the belief about sets as a well-defined collection of objects is merely doxa or true belief. This study emphasizes the importance of mathematics education in fostering justified true belief through a focus on critical thinking and conceptual justification, thereby minimizing the occurrence of the Zone of Concept Image Difference (ZCID) between teachers and students.

Abstract

Covid-19 is a dangerous disease that is easily transmitted, both through living media in the form of interactions with infected human, as well as through inanimate objects in the form of surfaces contaminated with the Coronavirus. Various preventive and repressive efforts have been made to prevent the spread of this disease, such as isolating and recovering the infected human. In this study, the authors construct and analyze a new mathematical model in the form of a three-dimensional differential equations system that represent the interactions between subpopulations of coronavirus living on inanimate objects, susceptible human, and infected human within a population. The purpose of this study is to investigate the criteria that must be met in order to create a population free from Covid-19 by considering inanimate objects as a medium for its spread besides living objects. The model solution that represents the number of each subpopulation is non-negative and bounded, so it is in accordance with the biological condition that the number of subpopulations cannot be negative and there is always a limit for its value. The eradication rate of Coronavirus living on inanimate objects, the recovery rate of infected human, and the interaction rate between susceptible human and infected human such that the population is free from Covid-19 for any initial conditions of each subpopulation were investigated in this study through global stability analysis of the disease-free equilibrium point of the model.

Abstract

Problem-solving skills are crucial in mathematics education as they are one of the mathematics learning objectives. However, based on PISA results, students' problem-solving skills in Indonesia are still low, necessitating efforts to address this issue. Based on this problem, this study aims to develop a valid, practical, and effective pop-up book learning media to improve problem-solving skills in geometry transformation materials. This developmental study used the ADDIE development model, which consisted of analysis, design, development, implementation, and evaluation. This research employed a quasi-experimental design using two classes with similar problem-solving abilities as the experimental and control classes, as demonstrated by an average balance test on pretest scores. Each class contains 31 students. Learning media is considered valid and practical if its validity and practicality scores are 61% or higher. Learning media is deemed effective if it can improve students' problem-solving skills, as evidenced by a t-test on the students' post-test scores. The research results show that the pop-up book learning media is very valid, with an average score of 81.25% from material experts and 83.33% from media experts. The pop-up book media is considered very practical based on the teacher's response score of 83.33% and students' response score of 84.11%. Additionally, the experimental class in this study showed a statistically significant improvement with a p-value of 0.004 (less than 0.05) compared to the control class; thus, the pop-up book learning media can be declared effective in improving students' problem-solving skills. Therefore, it can be concluded that the pop-up book learning media is very valid, practical, and effective in enhancing students' problem-solving abilities in geometric transformation.    Keywords: pop-up book, learning media, problem-solving skills.

Abstract

This research was conducted to determine the validity, practicality, and effectiveness of Kanoma’s learning media in improving the understanding of mathematical concepts in high school students in class X. This research applied development research design with the PLOMP approach developed by Tjeerd Plomp. The stages of development using the PLOMP approach include preliminary investigation, product design, construction, testing, and implementation. The population in this research were all ten-grade students at a vocational high school. The research sample consisted of 16 students in the experimental class and 14 students in the control class. These students were selected randomly using the cluster random sampling technique. The instruments utilized in the study included assessments by media experts, questionnaires for students and teachers, and pretest and posttest evaluations of mathematical understanding. The instruments given to media experts is used to validate the Kanoma media and its content. The questionnaires for students and teachers were used to test the practicality of the developed Kanoma media. These quistionnaires gathered feedback on how easy and useful the media was in a classroom setting. The pretest and posttest were designed to measure students’ understanding of mathematical concepts related to finding the roots of quadratic equations. The average value given by material experts from the two validators of Kanoma’s media is 0.82. The average value given by media experts from the two validators is 0.90. The results show that the Kanoma media was categorized as “very valid” by both material and media experts. This indicates that media was suitable for use by class X students in senior high school. Kanoma media is also classified as practical based on the average percentage of student and teacher responses. The responses from students scored 73%, categorized as “practice”. The responses from teachers scored 81%, categorized as “very practice.” Kanoma media is effective based on the Mann-Whitney Asyptotic Sig. (0.002) <α (0.05). The results showed a significant improvement in mathematical understanding. Students who used the Kanoma media had a better grasp of the mathematical concepts than those who did not.

Abstract

Analysis of Epistemological Obstacles Experienced by Indonesian Junior High School Students in Solving Mathematical Literacy Problems viewed from Algebraic Thinking Skills. The low level of mathematical literacy skills can happen due to learning obstacles. There are various learning obstacles, one of which arises from students' errors or limitations in understanding a particular concept and context of the material, known as epistemological obstacles. One effort to improve mathematical literacy skills is by optimizing algebraic thinking abilities. This is why algebraic thinking is considered a focus of review. However, many students who transition from concrete to abstract thinking experience obstacles in algebraic thinking, including students in grade VIII. This study aims to analyze the epistemological obstacles junior high school students face in solving mathematical literacy problems from the perspective of their algebraic thinking skills. The research method is descriptive qualitative with research subjects of grade VIII junior high schools in Jaten who were then selected two students from each group of high, medium, and low algebraic thinking. The research data includes algebraic thinking ability tests, mathematical literacy tests, and interviews. The study results show that students with medium and low algebraic thinking abilities experienced epistemological obstacles in solving mathematical literacy problems. In contrast, students with high algebraic thinking abilities did not have experienced epistemological obtacles. This study concluded that there are differences in the characteristics of epistemological obstacles between students in the medium and low algebraic thinking ability groups, as identified by the indicators of epistemological obstacles. Keywords: epistemological obstacles, mathematical literacy, algebraic thinkingDOI: http://dx.doi.org/10.23960/jpp.v14.i2.202495
