Abstract

Problem solving is defined as a series of activities that allow students to find solutions to problems. Students' thinking processes occur when processing data or information to solve problems. One way to help students maximize the thinking skills is to make their experience when solving problems with PISA model. But in reality, Students made many mistakes and have difficulty understanding the problem, making a settlement plan, lack knowledge of the prerequisite material, and have not been able to describe the reasons in detail regarding the solutions found. One of the possible solutions to improve and complete the structure of students' thinking in solving mathematical problems on the PISA model HOTS questions is defragmenting. This study aims to describe the changes of students' thinkingstructure in solving mathematical problems through defragmenting. This type of research is descriptive research with a qualitative approach. The research data consisted of students' answers, the results of thinking aloud, and the results of semi-structured interviews. The results showed that students experienced assimilation at the stage of understanding the problem, while at the stage of formulating strategies, implementing plans, and re-examining students' thinking processes, they experienced accommodation. This is because students need defragmenting to connect mathematical concepts to solve problems, correct errors, and complete incomplete problem solving steps.

Abstract

This study aims to find out the improvement of students' mathematics understanding ability on the material of the Two Variable Linear Equation System (SPLDV) with the application of problem-based learning (PBL). This type of research is classroom action research. This research was conducted on students of class X Multimedia in one of the Vocational High Schools in Cimahi City. At the beginning and end of learning students are given test questions. The subjects of this study were 15 students. In this study, the instrument used was 8 questions in the material for the Two Variable Linear Equation System (SPLDV) which focused more on the students' mathematical understanding ability regarding the material for the two-variable linear equation system.. The results of this study indicate that the aspects of students' mathematical understanding abilities have increased as seen from the questions tested in each test. Based on the results of the study, the authors concluded that the mathematical understanding ability of class X multimedia students of one of the Vocational High Schools in Cimahi City could be improved through problem-based learning.

Abstract

This study aims to determine mathematics communication ability of junior high school students based on gender in terms of solo taxonomy. In order to do so, we used qualitative method with interviews and tests. The instrument in the study was a communication skill test with 4 items of description based on a solo taxonomy and interview. We conducted the instrument to 30 junior high school students with 15 male students and 15 female students.. The results of this study indicate the percentage of student response quality in completing the written test about the set including male students at the prestructural level as many as 4 students or 26.7%, unistructural level as many as 1 student or 6.6%, multistructural level as many as 4 students or 26, 7%, at the relational level as many as 5 students or 33.3% and at the extended abstract level there is no while for female students at the practructural level as many as 1 student or 6.7%, the unistructural level as much as 1 student 6.7%, multistructural level 4 students or 26.6%, the relational level is 7 students or 64.6% and the extended abstract level is 2 students or 13.4%. Based on the result, we conclude that the quality of the responses of male and female students in solving mathematics are in the relational level, which female students have a higher percentage than male students. They already able to relate the information to solve the problems given by accurate and draw conclusions.

Abstract

Mathematics learning aims to develop all student’s mathematical abilities in obtaining good mathematics learning outcomes maximum. The important target in achieving these learning outcomes is by maximizing learning on problem-solving ability. Accordingly, the purposes of this research were to know how the implementation of mathematics teaching materials on problem-solving ability and to know the categories of the effectiveness of mathematics teaching materials on problem-solving ability. The research method used in this research is descriptive which was obtained from observation, questionnaires, and tests. The participants of this study were students of the seventh grade of Junior High School which consists of two classes. The results informed that there were three kinds of effectiveness, that is interaction effectiveness which showed 55% less effective category, effectiveness of understanding which showed 61.8 % quite effective category, the effectiveness of teaching materials on problem-solving abilities which showed 52.78 % less effective category. Furthermore, appropriate learning materials and the creativity of the teacher in delivering learning materials are considered to be implemented in the mathematic learning process.

Abstract

Recognizing place value is one of the basic skills in numeracy. Numerical ability can be seen through students' ability to recognize the place value of numbers. This study aims to analyze students' numeracy skills in terms of their ability to recognize place values in numbers. The research was conducted at one of the public elementary schools in the Central Lombok district. The type of research used is a descriptive survey. Data collection using tests. The instrument used is a place value test. The number of research samples was 110 elementary school students, with details of 53 low-grade students and 57 high-grade students. Data were analyzed using descriptive statistics. If viewed from the ability to recognize place values, students' numeracy abilities are included in the fairly good category. Overall out of 110 students 60% have recognized the place value of thousands. Most of the high-grade students already know the place value of the thousands, while the low-grade students are mostly still in the places value of units, tens, and hundreds. The number of students who know the value of the hundreds is 13%, the tens value is 16% and the unit value is 8%. The study also found fact that there were 3% of students were not familiar with numbers. Although overall students' numeracy skills are quite good, special attention needs to be given to high-grade students who are not able to recognize the place value of thousands and low-grade students who are not yet familiar with numbers.
