Abstract

This study aims to describe the validation process in the mathematical modeling of male and female students. The subjects of this study were male and female students at State Junior High Schools in Surabaya. Data collection procedures through the assignment of mathematical modeling problems and interviews. Data analysis refers to the validation typology of Czocher (2018). The results show that male students and female students have similarities in validating mathematical solutions obtained by repeating arithmetic operations performed previously. In addition, the two students equally succeeded in validating the real result found with consideration related to the effect of changing situation model and arithmetic operations. However, male and female students failed to generate a variety of models so that no activity emerged in generalizing the various solutions obtained. Male students are able to consider the influence of real context aspects on the solutions found, while female students are not. Female students can explain the real model that was built by mentioning the specified mathematical concepts and the reasons for using them, while male students are not.

Abstract

Future challenges that are increasingly complex require the competence of graduates who are not only skilled, but also creative. The process of creative thinking has four stages, namely synthesizing ideas, building ideas, planning the implementation of ideas, and implementing ideas. Open-ended math problems are a medium that teachers can use to find out students' creative thinking processes. The purpose of this research is to describe the process of creative thinking of junior high school students in solving open-ended math problems in terms of mathematical abilities. This research is a qualitative descriptive study conducted in 7th grade of SMP Muhammadiyah 2 Taman. The research subject was one student from each category of high, medium and low mathematical ability. Data collection methods used are test and interview methods. The results obtained were that at the stage of synthesizing ideas, subjects with high, medium, and low mathematical abilities did so based on experience in class with known formulas. At the stage of building ideas, subjects with high mathematical abilities considered convenience, subjects with mathematical abilities considered other ways, and subjects with low mathematical abilities considered logic. At the stage of planning the implementation of the idea of a high ability subject and is doing it smoothly and productively, the low math ability subject is doing it inefficiently. As well as at the stage of applying the idea, the subject of high mathematical ability fulfilled the creative thinking aspects of fluency, flexibility, and novelty, the subject of medium mathematical ability fulfilled the aspect of flexibility, and novelty, the subject of low mathematical ability only fulfilled the aspect of flexibility.

Abstract

The activity of finding solutions to math problems is not easy. Most of the seventh grade junior high school students had difficulties in solving problems related to one variable linear inequalities material. Students experience difficulties in solving problems at the Polya problem solving stage. The difficulties experienced by students can be helped by providing scaffolding. This study aims to describe the process carried out by students in solving mathematical problems in the material of one-variable linear inequalities, and to describe the provision of scaffolding in solving mathematical problems in the material of one-variable linear inequalities. This study uses the selection of subjects by administering tests. Thus, it can be seen clearly the stages of solving the questions carried out by students. The research was conducted at SMP Negeri 25 Surabaya, which was attended by 32 students of class VII. The PtLSV problems given are two questions. A total of three research subjects were taken from the initial test, of the three subjects who experienced difficulties at all stages of solving the Polya problem, they would be interviewed and given scaffolding. The results showed that students experienced difficulties in the process of solving mathematical problems in the material of one variable linear inequality. This can be seen from the results of the students' work which did not write down any information that was known and asked about the questions, students could not devise a solution plan for the questions given. Students do not carry out the completion plan, and students do not re-check the answers that have been obtained. Providing scaffolding in this study, adjusted the location of the difficulties experienced by students in solving problems. Keywords: Problem Solving, Scaffolding, One Variable Linear Inequality

Abstract

The process of knowledge construction can provide meaningful learning experiences for students. This is because students build new knowledge themselves by connecting one knowledge to another. The purpose of this qualitative research is to describe the process of new procedure’s construction using analogy. The subjects of the research consisted of three students of grade X high school (one student took the test individually, two students took the test in pair). Data analysis based on the APOS theory’s stage (Action, Process, Object, and Schema). At the action stage, both individual and paired students determine what is known and asked about the system of linear equations (SLE) in three variables problem based on analogy with the known things and asked about the SLE in two variables problem. They correctly determine the solution set of SLE in three variables. They also checked the correctness of the solution set of SLE in three variables correctly. At the process stage, they outline the steps of defining the solution set of SLE in three variables clearly. At the object stage, individual student cannot explain other methods of solving SLE in three variables, while paired students explain four other methods of solving SLE in three variables, that is the method of elimination, substitution, graphing, and matrix. At the schema stage, individual student cannot generalize some methods of solving SLE in three variables, whereas paired student generalize some methods of solving SLE in three variables. They also concluded the most effective method of solving SLE in three variables, that is the combined method. Individual student also explains that there is a SLE in three variables that has no solution, whereas paired students cannot explain it. They can construct new procedure well, despite errors in their process. In the process of new knowledge construction, the student's prior knowledge determines the quality of its construction process.

Abstract

Mathematical connection ability is one of the important skills in learning mathematics. When students are able to relate mathematical ideas, their understanding of mathematics deepens and lasts longer. Based on the data in the field, it was found that students were still unable to recognize and relate mathematical ideas. During mathematics learning, behaviors that lead to math anxiety and lack of self-confidence were also found. The purpose of this study is to analyze students' mathematical connection abilities in terms of self-efficacy and mathematics anxiety. This type of research is a descriptive qualitative research using mathematical connection test aids, self-efficacy questionnaires, and mathematics anxiety questionnaires to collect data. The subjects in this study were 6 students of SMK majoring in TBSM. The results showed that students who have high, medium, and low self-efficacy can meet 3 indicators of mathematical connection ability.
