Abstract

Abstract Mathematics understanding of students is not only about understanding the material but how students can use the knowledge they already have to apply in everyday life. The ability of students to take advantage of the role of mathematics in problems that occur in real life is called mathematical literacy. One of the materials that include solving mathematical problems and the mathematical literacy process of students at the junior high school level is the Two-Variable Linear Equation System (SPLDV). In solving SPLDV problems, students need problem-solving, reasoning, and communication skills. Many aspects can influence students in solving problems, including the ability of students' intelligence in facing a difficulty called Adversity Quotient. The purpose of this study is to describe the mathematical literacy of students in the quitter, camper, and climber categories in solving the problem of a two-variable system of linear equations. This research is qualitative descriptive research with a case study approach. Data collection techniques were carried out by giving SPLDV problem-solving tests and task-based interviews. From the results of solving the questions, 29 junior high school students in Paciran, the researchers chose 1 student from each category of a quitter, camper, and climber who had more complete and systematic answers than the other students. The results showed that there were differences in problem-solving of the three subjects in the components of formulating, interpreting, and applying.

Abstract

Mathematics is one of the disciplines and is a very important knowledge, especially in today's era of sophisticated technology. Creative thinking is a person's mental activity that produces new ideas that are relatively different from previously held knowledge that is useful for solving a problem at hand. Each student has different mathematical abilities that affect students' creative thinking process in solving math problems. The purpose of this study is to describe the creative thinking process of junior high school students based on high, medium, and low levels of mathematical ability in solving open ended problems on quadrilateral material. This research uses a qualitative approach with descriptive research type. This research was conducted on seventh grade students at Junior High School 2 Kesamben in the even semester of the 2022/2023 school year. Indicators of the stages of the creative thinking process in this study are synthesizing ideas, building ideas, planning the application of ideas, and determining ideas. The results of this study are students with high mathematics ability in (1) synthesizing ideas, namely by understanding, reading the problem two to three times, and identifying what is known in the problem; (2) building ideas, namely by sketching and imagining a rectangular flat shape as a first step to bring up the idea; (3) planning the application of ideas, namely by considering the ease of the method and using alternative ideas; (4) applying ideas, namely by writing down the steps that have been planned. For students with moderate mathematics ability in (1) synthesizing ideas by understanding, reading the problem twice, and identifying what is known in the problem; (2) in constructing ideas, namely by imagining the shape of a rectangular flat shape as a first step to bring up the idea; (3) planning the application of ideas by considering convenience and using alternative ideas; (4) implementing ideas by writing down the steps that have been planned. For students with low mathematics ability in (1) synthesizing ideas by understanding, reading the problem twice; (2) building ideas by imagining and describing the shape of a rectangular flat shape (3) planning the application of ideas carefully because they are sure they can solve the problem; (4) applying ideas by writing down the planned steps.

Abstract

This study aims to describe the problem solving ability of students with different mathematical abilities (high, medium, low) in solving ill structured problems of social arithmetic material. This research used a qualitative approach with descriptive research type. For the research subject, the researcher chose three seventh grade students at Labschool Unesa 2 Junior High School with different levels of mathematical ability (high, medium, low) and the same gender. Researchers used math ability tests, problem solving tests, and interviews to collect data. The mathematics ability test data was analyzed based on the range of student ability grouping Ratumanan and Laurens (2006), the problem solving test data was analyzed using Polya's problem solving ability indicators, and the interview data was analyzed using data triangulation (data reduction, data presentation, conclusion drawing). The results show that students with high mathematical ability have analyzed the problem well because students can consider all solutions to the problems given and the assumptions made by students are relevant to real life. Students have also entered the category of good problem solving skills. Meanwhile, students with medium and low mathematics ability have not been able to analyze the problem well because students only think of part of the solution to the problem given and the assumptions made by students are not relevant to real life. Students with moderate mathematical ability fall into the category of fairly good problem solving ability. Then students with low mathematics ability fall into the category of poor problem solving ability. These results can be used as an evaluation in the learning process or a reference for further research.

Abstract

This study aims to describe the mathematical literacy of junior high school students in solving statistical problems of PISA adaptation in terms of mathematics self-efficacy. The research subjects were ninth-grade students consisting of one student each with high and low mathematics self-efficacy. This research is qualitative research. Data were collected using a mathematics self-efficacy questionnaire, a mathematics literacy test on statistics problems, and an interview. Data analysis was based on mathematical literacy indicators (formulate, employ, and interpret). The results showed that students with high mathematics self-efficacy can identify mathematical aspects by determining the information known and asked in the problem (formulate), can design and apply problem-solving strategies to get solutions to problems (employ), and can draw conclusions from problem solutions and provide logical reasons and can provide conclusions by the context of the problem (interpret). Meanwhile, students with low mathematics self-efficacy can identify mathematical aspects by determining the known and questionable information in the problem (formulate), but cannot design and apply problem-solving strategies to get the solution of the problem (employ) due to errors in the use of concepts and calculations and can draw conclusions from problem solutions and provide logical reasons and can provide conclusions by the context of the problem (interpret).

Abstract

Abstract The addition of flip-worksheets to the statistics curriculum is anticipated to enhance students' capacity for critical thinking. This research is a development research that aims to create a worksheet supported by a Flipbook that is reliable and useful for teaching statistics and could influence students' critical thinking skill. Some exercises and open-ended questions from the provided infographics are included in the Flip-Worksheet. The worksheet uses mean, median, and modus material. The flip-worksheet was created during a formative evaluation stage with 15 junior high school students in the eighth grade. Data was analyzed using walkthroughs, questionnaires, interviews, and document reviews. According to the validation results, Flip-Worksheet is extremely valid in terms of media (89.58%), and it is valid in terms of material (79.43%). The practicality percentage was 90.74%. It is in an interval between 80% - 100% which falls into the very practice category. The N-gain value was 0.71. The grade VIII student's capacity to think critically increased as a result of using the Flip-worksheet which had high criteria. Additionally, based on the document analysis of students' responses about the process of interpretation, analysis, assessment, inference, explanation, and self-regulation on a variety of critical thinking tasks, it may have the effect of developing students' critical thinking abilities. It can be used as a learning medium and can develop critical thinking skills needed in the 21st century. It is hoped that next studies of learning media will be conducted in the future to enhance critical thinking abilities with other technologies.
