A Mathematical problem-solving ability is the ability of students to solve a mathematical problem. External factors that affect mathematical problem-solving ability are the methods and learning media used. Researchers apply the discovery method assisted by learning media which is one of the alternatives to improve mathematical problem-solving ability, namely the discovery learning model assisted by the Pythagorean Puzzle. This study aims to determine the effectiveness of discovery learning assisted by the Pythagorean Puzzle in improving the mathematical problem-solving ability of class VIII students of MTs Muhammadiyah 01 Purbalingga. This research is quasi-experiment research with a quantitative approach. The population in this study were students of class VIII MTs Muhammadiyah 01 Purbalingga which amounted to 163 students. The samples of this study were class VIII C which amounted to 22 students as the Experiment class and class VIII D which amounted to 22 students as the Control class. Data collection in this study used instruments in the form of observations and tests of mathematical problem-solving skills. Based on the analysis obtained, discovery learning assisted by Pythagorean Puzzle was implemented very well. The results of data analysis using the T-test, and post-test comparison test obtained sig (2-tailled) of 0.000 < 0.05, which means that there is a difference in the average experimental class and control class. So, it can be concluded that the implementation of discovery learning assisted by the Pythagorean Puzzle is effective in improving the mathematical problem-solving skills of class VIII students of MTs Muhammadiyah 01 Purbalingga.

Effectiveness of Realistic Mathematics Approach to Increasing Mathematical Representation Ability at SMP N 9 Purwokerto

2023-11-17T21:40:34+07:00

This research was conducted based on the low ability of students' mathematical representation in class VIII SMP N 9 Purwokerto. One of the contributing factors is that the use of the learning approach used has not facilitated students in developing mathematical representation abilities. The solution that is considered capable of increasing the ability of mathematical representation is to apply learning with a realistic mathematical approach. The realistic mathematics approach provides opportunities for students to do modeling, depicting and symbolizing related to concrete problems. This research is a quantitative research with a quasi-experimental type with Nonequivalent Control Group Design. The population in this study were all students of class VIII SMP N 9 Purwokerto. The sample in this study was class VIII A with a total of 36 students and VIII B with a total of 36 students. The data analysis used is the z-test and the N-Gain test. The results of this study indicate that the realistic mathematical approach is effective in increasing students' mathematical representation abilities. From the results of the z-test showed a significant effect, the mathematical representation abilities of the experimental class students were higher. Then the results of the N-Gain test showed that the experimental class was in the medium category and the control class was in the low category. Thus the representation ability of the experimental class students is higher than that of the control class.

Abstract: This study aims to determine whether there is an influence of the syllabus mind mapping method on the mathematical problem solving abilities of class VIII students of SMP Negeri 1 Karangreja, Purbalingga Regency. Mathematical problem solving ability is a quality possessed by someone to solve mathematical problems so that the goals to be achieved are resolved properly. One of the factors that influence the ability to solve mathematical problems is the model or method used in learning. The researcher chose to use the mind mapping method, a type of syllabus mind map, to improve students' mathematical problem solving abilities. This study used quantitative research (experimental) with a Quasi-Experimental Design. The population of this study were all class VIII which totaled 5 classes. The samples of this study were class VIII A, which consisted of 26 students and class VIII B, which consisted of 22 students. Collecting data in this study used a test consisting of a pretest and posttest. Data analysis used the t test and the N-Gain test using the SPSS version 25 application. The results of this study indicate that there is an influence of the syllabus type mind mapping method on the math problem solving abilities of class VIII students of SMP Negeri 1 Karangreja, Purbalingga Regency. The N-Gain results show that the N-Gain of the experimental class is included in the high category with an average N-Gain of 0.70 and the control class is included in the medium category with an average N-Gain of 0.54. So that the increase in students' mathematical problem solving abilities in the experimental class is higher than the control class.

Ethnomathematics in Batik Making Activities in Saung Baswet, Banjarsari Wetan Village, Banyumas

2023-11-16T08:21:34+07:00

Abstract: Ethnomathematics is a discipline that explores the relationship between culture and mathematics. In Indonesia, one culturally rich tradition is batik. The process of creating batik involves various stages that result in diverse motifs unique to each region. The aim of this research is to identify the ethnomathematical aspects related to the practice of batik-making, the batik motifs, and to analyze the mathematical concepts associated with batik. The research employs a qualitative ethnographic approach. Data is collected through interviews, observations, and documentation, and is subsequently analyzed using data collection methods, data reduction, data presentation, conclusion drawing, and verification. In the process of batik-making at Saung Baswet Village, Banjarsari Wetan, Banyumas, various mathematical activities such as calculations, measurements, designing, and motif placement are discovered. Some mathematical concepts revealed in batik motifs include points, lines, angles, as well as geometric transformations such as translation, rotation, reflection, and dilation. Additionally, there are concepts related to plane figures such as right triangles, rectangles, trapezoids, circles, and polygons, as well as concepts of symmetry, similarity, and congruence.

2023-11-15T13:36:18+07:00

Mathematics as a lesson that is useful for the development of thinking, thinking becomes an important process in it, where students are expected to be able to think deductively. Students are asked to understand the concept of the material that has been delivered with an active and conscious attitude, or referred to as a disposition. The purpose of this research was to find out the effect of mathematical disposition on students' mathematical creative thinking abilities in class XI MIPA MAN 2 Banyumas. The population in this research were all students of class XI MIPA totaling 243 students, 153 students were taken as samples using simple random sampling technique. This research was conducted using quantitative research methods where data was obtained by distributing research instruments in the form of questionnaires and tests. The analysis technique uses a simple linear regression analysis technique. Before the analysis test was carried out, the data went through analysis prerequisite tests, namely the normality test, regression significance test, and linearity test. The results of this study indicate that there is an influence of mathematical disposition on students' mathematical creative thinking abilities of 12,6%. Also regression equation obtained, Ŷ=8.325+0.730X which shows that the regression coefficient value is positive, which means that if the mathematical disposition (X) increases by 1 unit, the student's mathematical creative thinking ability (Y) will increase by 0.730 units.
