Abstract

Mathematics is a basic science which is about logic regarding form, structure, quantity and other related concepts. The ability to solve problems is basically the main goal of the mathematics learning process. The purpose of this study was to determine (1) whether there are differences in math problem solving abilities in each age range and (2) how to describe the ability to solve math problems in each age range. The method used in this research is quantitative research methods with a survey research approach. The instrument in this study was a questionnaire containing 3 mathematical problem solving questions related to everyday life which were uploaded to google form. The number of people who filled out the survey on the google form is 2085 people. The results showed that (1) there were differences in math problem solving abilities in each age range group, and (2) the age range group that had the highest problem solving ability was 43-48 years old, while the age range group that had the lowest problem solving ability was 43-48 years old. 55-60 years old.

Abstract

The purpose of this study was to describe student’s problem solving ability in term of mathematical ability in PLSV material. The research method was qualitative research. The subject of this study was 20 of students in grade 7B SMPN 1 Turen that chosen using purposive sampling technique. The Data collection used tests and interviews. The instruments used are a matter of tests and guidelines of interviews. Data analysis is conducted through three stages: data reduction, display data, and verification. The research results show that students with high category abilities has a high mathematical ability to solve the problems by accomplishing all the problem solving ability indicators, students with medium category abilities has a medium mathematical ability to solve the problems but have not accomplished all the problem solving ability indicators yet, and students with low abilities has a low mathematical ability, therefore it has not be able to solve all the problems.

Abstract

This research was conducted to review the mathematical elements contained in the cultural heritage building of the Watu Gudig Site (ethnomathematics). This research uses descriptive qualitative research methods with an ethnographic approach. To obtain accurate data, it is done by observing, interviewing and researching archives. Observations were made to determine the mathematical elements contained in the Watu Gudig Site. Interviews were conducted to obtain cultural aspects of the Watu Gudig Site. Archival research was carried out by triangulation technique, which means analyzing data from different sources to support the data that has been obtained from observations and interviews. The results of this research are found the concept of plane geometry in the cultural heritage building of Watu Gudig Site. The geometric concepts contained in this building are in the form of a square, trapezoid, rectangle, and block.

Abstract

This study aims to determine whether there is a positive and significant correlation between perceptions of mathematics, independent learning, and parents' attention to mathematics learning achievement class X students of SMAN 1 Parittiga. The research method used is ex post facto. The population of this research is all students of class X at SMAN 1 Parittiga, with 35 students taken by cluster random sampling. The data was collected by questionnaire and test. The instrument used fulfills the validity and reliability test. Analysis prerequisite tests include normality, linearity, and multicollinearity. Hypothesis testing using multiple linear regression test and partial correlation test. The results showed that the tendency of high mathematics perception, very high independent learning, high parental attention and high mathematics learning achievement. The multiple correlation coefficient (R) is 0.867 with sig = 0.000 <0.05, and you get SE (X1) = 6.9%, SE (X2) = 61.2%, and SE (X3) = 7.2%.

Abstract

This study aims to develop a flipped classroom based mathematics learning tool for building flat-side space in junior hidg schools. This study uses the research abd development method with a 4D model that is modified into 3D due to the covid-19 pandemic, so it pnly contains the define, design, and develop proceses. The results showed that the average validation result by expert validators for RPP was 4,4 (very valid) and the average validation result by stakeholders was 4,65 (very valid). The average result of validation by expert validation for LKPD is 4,49 (very valid) and the average result of validation by stakeholder is 4,74 (very valid). So that the result of the evaluation of the lesson plan by the experts and stakeholders obtained a mean score of 4,53, while the overall mean of the evaluation result of the LKPD by the expert validator and stajeholder obtained a mean score of 4,6. This shows that the flipped classroom based mathematics learning device in junior high school is suitbale for uses as a reference for learning mathematics subjects.
