This study aims to describe the statistical thinking process of high school students in solving mathematics problems. The method used was descriptive explorative with a qualitative approach, which was conducted at Maarif Lawang High School. The research subjects consisted of 24 students in class X MIPA who had taken statistics material. After being investigated, there were 3 out of 24 students who had solved the problem correctly. Based on the statistical thinking process, it can be grouped into two, namely the complete group and the incomplete group. One person in each group was taken as a group representative. Students completed the test with one data centralization problem. Written exams and in-depth interviews were the means of data collection. The data were next subjected to analysis using data reduction techniques, data display, and the drafting and verification of conclusions. Triangulation techniques were used to assess the veracity of the data. Based on the study's findings, Subject 1 accurately solved the problem and demonstrated proficiency in all four stages of the statistical thinking process: describing data presentation, organizing and reducing data, representing data, and analyzing and interpreting data. Although Subject 2 is capable of finding the proper solution, they are lacking in three key areas of statistical thinking: explaining the presentation of data, organizing and decreasing data, and expressing data.

Culture has an important role in facilitating students' mathematical creative thinking skills. The use of cultural context in mathematics learning helps students to understand mathematical concepts in a more relevant and real way. The results of the initial study conducted by the researcher indicated that there are still many students whose mathematical creative thinking skills are still low and teachers still have difficulties in developing appropriate assessments to measure creative thinking skills. This study aims to develop assessment instruments using the Jambi cultural context in measuring the mathematical creative thinking skills of junior high school students that are of high quality (valid, practical, and effective). This development research uses the Plomp development model. The development stages include the initial investigation stage, the development and prototyping stage and the assessment stage. The research subjects were 29 students of class IX.A and mathematics teachers. The results of the study were the quality of the product assessment was valid 3.6 with ‘very valid’ criteria, practical with an average teacher response questionnaire score of 3.25 and an average student response questionnaire score of 2.80 and effective with good differentiating power. The assessment developed is of high quality, namely valid, practical and effective. Thus, this assessment can be used by teachers directly or modified as needed to measure students' creative thinking skills.

Representation is an important element in mathematics learning that helps make abstract mathematical ideas more concrete. Changes between forms of representation, called translations of mathematical representations, are necessary in mathematics learning. However, students often struggle with this process, as evidenced by errors in problem-solving. These errors can be categorized into three types: interpretation errors, implementation errors, and preservation errors. Based on these facts, a solution is needed to overcome student errors. However, to formulate the right solution, an in-depth study is needed regarding student errors in translation. Therefore, this study aims to analyze and describe junior high school students' errors, especially in translating representations from symbolic to graphical form in quadratic function material. The method used is descriptive qualitative, involving three class IX students with different mathematical abilities as research subjects. The results of this study showed that high-ability students made few interpretation, implementation, and preservation errors from the stage of unpacking the source to constructing the target. Moderate-ability students made some interpretation and implementation errors from the stage of unpacking the source to constructing the target. Meanwhile, low-ability students made many interpretation, implementation, and preservation errors from the stage of unpacking the source to determining equivalence. To overcome these errors, teachers can apply level 1 scaffolding (environmental provisions) and level 2 scaffolding (explaining, reviewing, and restructuring). In conclusion, students with different mathematical abilities each have difficulties in making translations. The factors causing these errors include inaccuracy, neglect of important aspects, inappropriate habits, and conceptual errors.

Linear pattern is the primary material in learning number patterns in junior high schools, but there are still many students who fail to generalize the linear pattern. The students’ failure in generalizing the pattern occurred when the students ended to view the problems globally without breaking them into the constructors’ components such as the experience of field-dependent type students. For this reason, this study was carried out to explore the thinking process of students who fail and investigate the thinking processes of students who succeed in generalizing linear patterns. The results of this study provide an effective learning strategy solution for field-dependent students in generalizing linear patterns. This study employed a qualitative approach with a case study design to junior high school students. The results indicated that students in the field-dependent cognitive style looked at pattern questions represented in the form of geometric images globally without looking at the structure of the image. Two strategies for generalizing linear patterns used by field-dependent students were examined, namely recursive and different strategies.

Online learning experiences have been associated with reduced learning outcomes and limited student engagement in argumentation. To address this issue, the focus on teaching materials becomes crucial, especially in promoting differentiated learning to accommodate pandemic-induced learning losses. A prime candidate for enhancing argumentation skills is the study of quadrilaterals within mathematics. Mastering the quadrilateral concept and its argumentative structure is pivotal for students. Hence, the creation of student worksheets employing differentiated learning principles is imperative. This research aims to develop valid, practical, and effective quadrilateral worksheets with a focus on adversity quotient differentiation. The ADDIE model guides the development process through Analysis, Design, Development, Implementation, and Evaluation stages. Rigorous evaluation, including expert validation (83.8% very valid), field trials (91% very practical), and N-Gain score analysis (0.73, indicating effectiveness), underscores the quality of the developed worksheets. In conclusion, the adversity quotient differentiated quadrilateral worksheets has been successfully crafted to enhance students' argumentation skills. It is deemed valid, practical, and effective in improving learning outcomes. This initiative holds potential for addressing the challenges posed by online learning and contributes to students' academic development.

Integers are an important topic in mathematics that students must understand well. However, in practice, many students face difficulties in understanding integer operations. One way to address this issue is by using a number line manipulative that employs Dienes' steps. This research is qualitative, with a case study approach. The subjects consisted of three 6th-grade students selected through purposive sampling. The three subjects had varying mathematical abilities: high, medium, and low. The learning activities used six steps of Dienes. The instruments used were observation sheets, interview guidelines, and a test consisting of eight questions related to the addition and subtraction of integers. Data collection techniques followed the Miles and Huberman model, which includes data reduction, data presentation, and drawing conclusions. The results of the study indicate that learning using Dienes' steps with integer manipulatives successfully addressed students' difficulties in performing integer operations, especially in problems involving operations with two adjacent signs.

This research is a qualitative descriptive research which aims to explore students' creative thinking process in completing MST on geometry material. The creative thinking process of each individual is different according to their level so it is necessary to analyze how students' creative thinking process is in completing MST based on level of creative thinking. Researchers refer to the stages of creative thinking developed by Wallas consisting of preparation, incubation, illumination and verification stages. Researchers focused subjects on the 5 levels of creative thinking developed by Siswono in the stages of creative thinking, namely subjects with levels of creative thinking level 4 (very creative), 3 (creative), 2 (quite creative), 1 (less creative), and 0 (not creative). Each level is described starting from the preparation, incubation, illumination and verification stages. Based on the research results, there are differences in creative thinking processes at each level of creative thinking, especially at the verification stage, only students with creative levels 4, 3, and 2 carry out the verification stage; The incubation stage for students with creative levels 2, 1, and 0 takes a long time so that subjects with a long incubation stage are not optimal in completing MST to get many alternative solutions. Keywords: geometry, multiple solution tasks, creative thinking process.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp248-263

Metacognition is one aspect that supports individual success in solving mathematical proof problems because using metacognition when solving problems will produce effective results. This research aims to collect information about students' metacognition in solving mathematical proof problems. This research applies a qualitative escriptive approach. There were 30 Mathematics Education students involved in this research from Universitas Negeri Malang. The way to obtain data in this research uses a mathematical proof test and interviews. The results obtained from this research reveal that the metacognition experienced by students consists of awareness, regulation, and evaluation. However, the metacognitive activities of the first student were different from other students. This is because each individual’s metacognition is different even though both have the same problem-solving abilities.
