<![CDATA[Translation is a process of transforming information from source representation to target representation. The translation process is described in four activities, such as unpacking the source, preliminary coordination, constructing the target, and determining equivalence. This study aims to analyze and describe the translation process of mathematical representations from verbal to symbolic in UM Mathematics S1 students in solving statistics on variance and standard deviation material. The instruments used were translation test questions and interview guidelines. Data analysis focused on four translation activities which were then categorized (high, medium, low). The results of the research percentage show that 78.58 percent of students experience difficulties in translating representations from verbal to symbolic in statistical problems. This is because students make mistakes in interpretation and implementation. While 21.42 percent of students succeeded in translating representations in solving the variance and standard deviation problems that have been presented. In terms of categorization, 21.42 percent of students belong to the high category, 39.29 percent of students belong to the medium category, and 39.29 percent of students belong to the low category. At this stage, the researcher obtained 28 student subjects for further analysis through 4 (four) stages of translation.]]>

<![CDATA[Reflective thinking begins with repeated confusion and evaluation to solve a problem. There are four aspects to reflective thinking, namely techniques, monitoring, insight, and conceptualization. However, the problem-solvers’ reflective thinking characteristics in mathematical problems have not been discovered. The study describes the reflective thinking characteristics of proficient mathematics prospective teachers based on four aspects. The qualitative research was conducted at Universitas Muhammadiyah Surakarta with a total of 64 reflective thinkers. Data collected by test, observation sheets, and interview methods. The tests were administered twice. The instruments developed has been through the validation process and declared valid. Data analyzed through the stages of reduction, presentation, and verification. We successfully conclude that proficient mathematics prospective teachers have complete and consistent reflective thinking characteristics. Further research can be focused on the characteristics of reflective thinking based on another aspect.]]>

<![CDATA[Evaluation of the argumentation structure is needed to check the quality of student argumentation to produce appropriate problem-solving. Such evaluation can be carried out by identifying the constituent components of the argument. This study aims to describe the structure of student argumentation in solving statistical problems based on the Adversity Quotient (AQ). This qualitative descriptive type of research involved 52 students who were taking statistical methods courses. Participants were classified into three Categories of Adversity Quotient based on the results of the ARP (Adversity Response Profile) questionnaire. Data were obtained using statistical problem tests and interviews. The results showed that students with the AQ Climber category were able to meet all the constituent components of argumentation when solving statistical problems. AQ Camper-type students are only able to meet three components, namely claims, evidence, and reasoning. Meanwhile, students with the AQ Quitter type are only able to fulfill one component, namely claims. Based on the results of the study, the level of Adversity Quotient determines the quality of the student's argumentation structure when solving statistical problems.DOI: https://doi.org/10.22342/jpm.16.2.16633.121-140]]>

<![CDATA[In the analytical balance sheet of the base money monetary authority, Bank Indonesia explained that net foreign assets (NFA) affected the circulation of base money, including currency. This gives an assumption regarding the indication of a causal relationship between currency circulation and NFA. In addition to the causality test, the primary purpose of this study is to identify long-term equilibrium relationships between NFA and Currency Circulation. The cointegration test obtained r = 1, indicating cointegration (long-term equilibrium). Time series data plots of these two variables tend to have a trend and are not stationary. The Vector Error Correction Model (VECM) is applied as an analytical method used to correct long-term relationships between variables that are not stationary. However, in the concept of VECM deviation and short-term dynamics, the association is assumed to be linear. At the same time, in applying economics, the relationship between economic variables is not necessarily linear. The significance test for the presence of a threshold using a fixed regressor bootstrap shows a threshold effect or nonlinear VECM, so it is necessary to use an analytical method that can combine nonlinearity and cointegration through the Threshold Vector Error Correction Model (TVECM). In this study, modeling of TVECM 2 regimes and three regimes were carried out. TVECM 3 regimes obtain the best model with two threshold values of -310850 and -260156.]]>

<![CDATA[Problem solving is one of the main goals in learning mathematics and can be realized in solving story problems. The purpose of this study is to describe the difficulties of climbers, campers and quitters' students in solving mathematical problems in the form of story questions based on Polya's steps. This research uses qualitative research with a case study approach design. The instrument is the researcher himself and the supporting instruments are questionnaires, problem solving test instruments and interviews. The population in this study were students of SMPK Mardi Wiyata Malang class VIII B which were taken 6 subjects (2 Climber students, 2 Camper students and 2 Quitter students) based on the results of Adversity Response Profile (ARP) questionnaire data. The results in this study consist of the difficulty of climber students in solving problem solving, namely the difficulty in solving problems and making conclusions from the problems that have been solved. Camper students' difficulties in solving problem solving are difficulties in planning problem solving strategies, problems solving and drawing conclusions from the problems given. The difficulty of quitter students in solving problem solving is the difficulty of students in understanding problems, planning solutions, making solutions and drawing conclusions from the problems given. Based on the findings, students with the quitter category have the lowest ability in the problem-solving process. Therefore, further research is needed to increase the motivation and interest in learning of students belonging to the quitter category.]]>

<![CDATA[One of the subjects that can measure students' problem solving abilities is geometry because geometry discusses objects, definitions, symbols and images that can be used as ideas or ideas by students. This research is a descriptive qualitative study which aims to describe and analyze students' ability to solve problems based on Polya's steps in terms of self-regulated learning (SRL). The subject of this research is one student in each SRL (high, medium, low). Data collection methods are questionnaires, tests and interviews. The results showed that 12.5% of students had high SRL levels, 70.83% had medium SRL level students and 16.67% had low SRL level students. Students with high SRL can complete problem solving according to Polya's steps. Students with moderate SRL can apply the steps of understanding the problem (writing the information available and what is being asked) and the planning steps. Meanwhile, students with low SRL can understand the problems in the questions. Based on interviews students can only provide information from what is contained in the questions but do not have ideas to solve them. Students with low SRL are only able to do the first of the four stages of problem solving. So, it can be concluded that the higher the SRL or the level of one's learning independence, the higher the ability to solve problems.]]>

<![CDATA[This study aims to describe students' mathematical literacy skills in solving statistical literacy questions based on Honey-Mumford learning styles. The statistical literacy questions used in this study are questions of the AKM type which are related to statistical material about the size of data concentration. The subjects of this study were first semester students of the Department of Mathematics, State University of Malang. The instruments used in data collection were test questions, interview guidelines, and instrument validation sheets. The results of the study show that there are differences in the level of students' abilities in several aspects that become competencies in mathematical literacy. Students with a reflective learning style tend to be more detailed in terms of using symbols and mathematical formulas, students with a theoretical learning style tend to be more thorough in understanding and translating the meaning of the questions, while students with a pragmatic learning style tend to prefer using simple reasoning with minimal use of mathematical symbols/formulas.]]>

<![CDATA[The role of arguments in solving mathematical problems is very important. Students must use valid arguments and concepts that have been learned in the Probability Theory material to build their arguments. An argument can be analyzed using the Toulmin scheme. Therefore, the purpose of this study is to describe the arguments that have been built based on the Toulmin Argumentation Model. The instrument used to collect data is a test question related to the Probability Theory material. Of the 32 students who worked on the test questions, three students were selected as research subjects. The selection of research subjects is based on the ability of students' mathematical ability level in working on test questions. It was found that students can construct an argument starting with the correct data. However, they did not give any Warrant and did not even give a Claim to their argument. This makes the argument built by students is invalid]]>
