Abstract

The Academic Potential Test is a test that aims to measure a person's abilities in the general academic field. This test is also often associated with intelligence. Currently, apart from selecting prospective students at universities, The Academic Potential Test has also become a standard test in the selection of Civil Servant Candidates and in the recruitment of private employees and employees of State-Owned Enterprises. Based on the background above, it is necessary to measure the ability of students from the Mathematics Education Study Program at Catholic University Weetebula in solving test questions. This needs to be done as a first step in determining the abilities of prospective graduates. The method used in this research was by giving a written test in the form of test questions to 56 students and interviews with 9 students who took the test. The instruments used were 40 test questions and an interview guide. The data analysis techniques used are reduction, presentation and drawing conclusions. The test results show that students who get the low category are 84%, students who get the Average category are 7% and students who get the high category are 9%. The interview results showed that students were able to understand the test questions given, but students had difficulty determining how to solve them, so students were unable to determine the correct answer

Abstract

The purpose of this study is to describe students' errors in solving quadratic equation problems. The subjects of the study were grade IX B students of SMP Negeri 1 Loura with a total of 13 students. The type of research used is descriptive qualitative using research instruments, test sheets and interviews. The tests used are quadratic equation material questions, while the type of interview conducted is in the form of semi-structured interviews. The results showed that reading error was 0.0%, problem misunderstanding error was 40%, problem transformation error was 60%, process skill error was 75%, final answer writing error was 20%. Student errors are caused by several things including: lack of understanding of the concept of quadratic equations, not focusing and not being careful in doing problems.

Abstract

This research aims: to find mathematical aspects found on the roof of a loura traditional house, apply the mathematical aspects found in learning the roof of a loura traditional house. This research was conducted at SMKN 2 Tambolaka City class X. This type of research is research and development (Research and Development). Data are obtained from the results of filling out observation sheets and, tests and taking documentation. Loura traditional houses have mathematical aspects such as triangles. The results obtained from the implementation of the research showed an increase, this can be seen from the results of student answers on student worksheets and an increase in student activity in terms of questions and answers in class and their active and critical way of thinking. Likewise, the learning outcomes of each action showed improvement. Thus, it can be concluded that the use of learning media in trigonometry material on the roof of a loura traditional house at SMKN 2 Tambolaka City based on the results of research can improve mathematics learning outcomes and teachers can try to apply this method so that students are active and motivated in learning mathematics

Abstract

The purpose of this study is to determine students' mathematical communication skills after the application of the problem based learning model of number pattern material in grade VIII students of SMP Negeri 4 Loura. The type of research is a descriptive qualitative method. Data collection uses interviews and documentation. The data analysis process is carried out qualitatively consisting of data reduction, data presentation, and conclusion drawn. The results of the study showed that from each level of the percentage level of the student communication ability category, namely the percentage level of the high category was 20%, medium 20% and low 60%. The impact of this ability is that students do not relearn the material that has been given during learning and do not pay attention to the researcher delivering the material

Abstract

In general, the North Wewewa Wewewa Woven Fabric of Bokuna Village is passed down from the ancestors and followed until now this Woven Fabric has beautiful motifs made based on daily life and also from nature. Ethnomathematics is a bridge between culture and mathematics, ethmomathematics is adapted by cultural groups to see that the culture contains mathematical aspects. This research aims to find out the concept of geometry in Woven Fabrics. The data collected is in the form of documentation, interviews, and observation results. The type of research used in qualitative descriptive is to describe the mathematical elements contained in woven fabrics. Data collection uses observation and interviews. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the analysis show that Woven Fabrics are sacred crafts that are inherited from ancestors or from generation to generation. In the study, the researcher found several one-dimensional and two-dimensional buildings. The geometric shapes found by the researcher are: rectangular shape on the entire shape of the woven fabric, an equilateral triangle shape on the mamuli motif, an isosceles triangle shape on the flower motif, a bele ketupat shape on the star motif, a rectangular shape on the entire woven fabric, a square shape on the butterfly motif

Abstract

This study aims to find out the difficulties of students in solving PLSV problems using the demonstration method for grade VII students of SMP Negeri 5 Lamboya. This study uses a qualitative approach with a descriptive method. 14 students as subjects to be researched to the extent to which the students can work on one-variable lienar equation problems. The data collection methods used are tests, interviews, and documentation. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that there was still a lack of ability of students to solve PLSV questions that answered the questions correctly and incorrectly. The results of the analysis for problems number 1, 2 and 3 were at the stage of difficulty in interpreting mathematical language (59.66%), the stage of difficulty in using data (64.33%), the stage of difficulty in mastering concepts correctly (66.66%), the stage of difficulty in using calculation operations (66.66%), and the stage of difficulty in drawing conclusions (83.33%). The cause of incompetence is that students do not read the questions carefully so that they make mistakes in writing down what is known and what is asked, so that they are less able to solve problems, in a hurry so that others are incomplete.

Abstract

This study aims to improve the learning outcomes of fourth-grade students at SDK Wanno Badu. This type of research is Classroom Action Research (CAR). The subjects of this study are fourth-grade students at SDK Wanno Badu, totaling 17 students, comprising 9 female students and 8 male students. Data were collected through (1) learning outcome tests, observation, and documentation. Data analysis was carried out using descriptive quantitative and qualitative methods. The results of the observation of teacher activities in managing learning for each cycle, taking into account the average achievement, continued to show an increase from cycle I to cycle II. The teacher activity observation score in cycle I was 80.35, which falls into the good category. In cycle II, there was an increase to 98.21, which is in the very good category. The very good achievement in cycle II indicates that the activities in managing learning to improve student learning outcomes using the STAD-type cooperative learning model were highly effective. The observation results on the students also showed an improvement, namely in cycle I the average score reached 76.78 with a good criterion, and in cycle II it increased to 93.74 with an excellent category. From this research, it was found that in cycle I the average percentage score was 71.76% and the classical completeness was 58.82%, and in cycle II the average percentage score was 84.11% and the classical completeness was 88.23%.
