Abstract

This study explores the elements of mathematics (geometry and arithmetic) in Sewu Temple. As the research is qualitatively discussed, ethnographic design is appropriately implemented with observation, interviews, and documentation for collecting data. The data analysis technique shares four steps; collecting, reducing, presenting, and drawing a conclusion"”the validity of the data using triangulation techniques. The results of this study indicate that there are mathematical elements in the shape of the building and the reliefs of Sewu Temple; flat shapes, spatial shapes, geometric transformations, and arithmetic sequences. The existing flat forms include; squares, rectangles, isosceles trapezoids, right trapezoids, circles, triangles, and octagons. Furthermore, blocks, tubes, and rectangular pyramids are included in existing shapes. The geometric transformations are in the form of reflection (mirror), translation (shift), and dilation (multiplication). The results of the ethnomathematical exploration at Sewu Temple can be used as instructional teaching for mathematics in schools, especially in geometry, geometric transformations, and arithmetic sequences.

Abstract

Generalization ability need to be encouraged in learning mathematics, students with generalization abilities can expand and transfer knowledge to practical knowledge. This research aims to develop learning material based on realistic mathematisc approach that oriented to generalization ability. The learning materials'developed is lesson plans and student worksheets. This is research and development with an ADDIE model. The instruments used in this study were the evaluation sheets, response questionnaire for teachers and students and tests of mathematical generalization ability.  The data analysis technique used was descriptive qualitative and quantitative. The design of the learning materials focuses on aspects of the mathematical generalization ability of high school students by presenting real problems. Student activities are designed to solve real issues related to pattern analysis, focus on student contributions to find conjectures, and design interactions so students can proceed to the abstraction stage using concept linkages. So students can make conclusions regarding the given concept in response to such issues. The results show that the validity qualifications of lesson plans and student worksheets are good and very good, the practical qulifications are very good. The learning materials comply with effective based on completeness tests of generalization ability of 82.26 with good qualifications

Abstract

The research aims to analyze narratively critical thinking and communication skills using the Android-based TransGeo application on geometry transformation in junior high school. This study uses a qualitative with a descriptive method obtained from tests and interviews. The test contains contextual problems in the android application, while the interviews are based on student test answers. Then, test results are adjusted descriptively by presenting the achievement of each student to be categorized based on critical thinking and communication scoring. Next, one student was randomly selected from each category as the interview subject. The indicator of critical thinking skills is the most difficult to achieve in the fourth indicator. Students are less precise in writing conclusions related to the initial problem; the indicator that many students succeed is the first indicator where students have written what is known and asked in difficulties. The indicator of communication skills is the most difficult to achieve in the second indicator. Students did not describe or write mathematical sentences to present an explanation of the transformation type or final position area in the problem. Many students achieve the first indicator, where they have written what they know and are asked about.

Abstract

This study aims to analyze the effect directly or indirectly between learning styles and the learning environment through independent learning on students' cumulative grade point average in the Mathematics Education Study Program, FKIP Undana. The type of research is quantitative research, with the research population being all active students in the Mathematics Education Study Program. The sample taken was 95 people. The samples were based on the Slovin formula with an error of 5%. Data was collected through questionnaires regarding the learning environment, learning styles, learning independence, and GPA. The data collected was then analyzed by path analysis. From the results of the data analysis, it was concluded that 1) there is a significant direct effect between learning styles on student learning independence; 2) there is a significant direct effect between the learning environment on student learning independence; 3) there is no significant direct effect between learning styles on students' GPA; 4) there is a significant direct effect between the learning environment on the student's GPA; 5) there is a significant direct effect between learning independence on the student GPA; 6) there is a significant direct effect between learning styles through independent learning on the student's GPA; 7) there is a significant direct effect between the learning environment through independent learning on the student's GPA. Overall, it can be concluded that there is a significant influence between the environment and learning styles through independent learning on student GPA.

Abstract

This research aims to determine the magnitude of the influence of the discovery learning model on students' mathematical abilities. These included problem-solving skills, critical thinking, understanding, and mathematical reasoning. This study employs a quantitative approach with a Meta-Analysis method. Data collected was from experimental research connected to the application of discovery learning models to the mathematical abilities of elementary, junior high school, and high school students in papers indexed from 2012 to 2021. From the search and study selection results, 48 articles were obtained. The findings found an annual increase in the number of publications, most of which were on mathematical reasoning abilities. Researchers also conducted more research at the junior high school education level, with a sample size of more than 30. Meanwhile, when viewed from the demographic aspect, this study is more located on the island of Java. The application of the discovery learning model to students' mathematical abilities has an overall effect size of 0.815 with the high effect category.

Abstract

This study is a survey research with a cross sectional survey design, which aims to describe the ability of junior high school mathematics teachers in writing HOTS items. The population of this study was junior high school mathematics teachers in Sleman Regency, while the sample was 21 teachers determined by non-stratified random sampling. The sample teachers came from 11 schools totaling 21 teachers.  Each teacher created three HOTS items along with their grids. The question items made by the sample teachers were descriptive questions. The question items that had been prepared were then reviewed by two mathematics teachers from leading junior high schools in Yogyakarta. The next stage after validation is the trial. The number of respondents used was 263 students for testing teacher-made questions, namely 127 students in class VIII and 136 students in class VII. The results showed that the quality of the questions produced by the teacher based on the reliability estimation results obtained an estimate of 0.635 for class VII and 0.416 for class VIII. Likewise, the resulting differentiating power is less than 50% of the questions made by teachers who have differentiating power in the good, good, and very good categories. Factors that cause this include the lack of experience of teachers in writing HOTS questions. This is a special note to familiarize teachers with using HOTS questions in daily tests, UTS, and UAS proportionally so that the experience and ability of teachers to write HOTS questions increases.
