<![CDATA[The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.]]>

<![CDATA[This study aims to analyze the influence of differences in learning models on problem-solving ability, the influence of differences in student learning styles on problem-solving ability, and the interaction between learning models and student learning styles on problem-solving ability. The design of this study is a pseudo-experimental design. The samples in this study were students of class VII A and class VII C of SMP Negeri 3 Muntilan who were selected by cluster random sampling. Based on the results of the hypothesis test conducted with the two-way ANAVA test, the results were obtained that 1) there were differences in the influence of learning models on problem-solving ability; 2) there is no difference in the influence of the four learning styles on problem-solving ability; 3) there is no interaction between the learning model and the student’s learning style on problem-solving ability. The conclusions of this study are 1) students with ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models; 2) students with convergent, divergent, assimilated, and accommodation learning styles with an ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models.]]>

<![CDATA[This study aims to explore ethnomathematics in the traditional game Galasin in Jakarta on mathematical concepts such as gradients, point to point distance, and vectors. This study uses an ethnographic approach to obtain a description of an in-depth analysis of a culture based on the information that has been obtained and by conducting observations and interviews in data collection. This research focuses on one of the traditional games in Jakarta, namely the Galasin game as a form of understanding ethnomathematics in mathematical concepts such as vectors, gradients, and point to point distances. This shows that the traditional game Galasin in Jakarta has a connection with mathematical concepts and forms of deepening in previous studies which have links with geometric mathematical concepts such as flat shapes. The existence of traditional game media in learning mathematics can provide benefits, namely visualizing mathematics learning in a real form so that students become more understanding and easier to understand learning the mathematical concepts being studied.]]>

<![CDATA[This research was conducted at MTs Sunan Muria Ploso with the aim of describing the application of realistic mathematics education material of row and arithmetic series. Some research said that, in schools, applies mathematical concepts directly which causes students to feel bored quickly and the methods used are less varied. In order for mathematics learning to be creative, interesting and fun, then one way is to apply the Realistic Mathematics Learning approach. This research is a descriptive qualitative research with 40 students of class VIII-D MTs Sunan Muria Ploso as the subjects. Data collection techniques using the method of documentation, and interviews conducted by researchers with students. Data collection techniques using the method of documentation and interviews conducted by researchers with students. The sampling technique used was purposive sampling. The data analysis technique in this research is qualitative data analysis, which consists of data reduction, data presentation, and drawing conclusions. The research instrument is a test and interview guide. The results showed that the arithmetic series material can be applied well with the RME approach.

<![CDATA[This research is a qualitative descriptive research conducted to describe the completion of numeracy problems and determine the level of numeracy ability of junior high school students. The subjects in this study were 34 students who were grade VIII junior high school students in Ciledug District. The research instrument is a written test with three numeracy ability test description questions where each question contains three indicators of numeracy ability. The results showed that the numeracy ability of junior high school students was still classified as low, because there were 19 students who were only able to meet a maximum of one numeracy ability indicator. The percentage of numeracy ability test acquisition is 11.76% of students in the high category, 32.35% of students in the medium category, and 55.88% of students have low numeracy ability.]]>

<![CDATA[This study aims to determine the effect of interest in learning mathematics on the understanding of mathematical concepts in grade VIII junior high school students in the matter of number patterns. Number pattern material is one of the materials contained in the 2013 curriculum for class VIII which is expected to be mastered by students and students because it is closely related to everyday life. In this study the population was all class VIII students of SMP Negeri 28 Tangerang for the Academic Year 2022/2023. The sample selection was carried out in this study by means of probability random sampling, namely class VIII-D students as many as 36 students. The approach used in this research is quantitative and analyzed by simple linear regression. The technique of collecting data by providing non-test instruments in the form of questionnaires on students' interest in learning mathematics and test instruments on the subject of number patterns to measure understanding of mathematical concepts that are closely related to everyday life. Hypothesis testing is done by simple regression with prerequisite analysis, namely testing the normality of the data and the linearity of the data. The results showed that there is no significant effect of interest in learning on understanding mathematical concepts with the regression equation . So it can be concluded that interest in learning affects students' ability to understand mathematical concepts in an insignificant way.]]>
