Abstract

The aim of this research is to describe the difficulties faced by students in solving problems in three-dimensional material with the subject being 2 students in class XII MIA. This research is a type of descriptive qualitative research. The data analysis technique used was a qualitative data analysis technique by selecting 2 students from 53 students to be used as interview subjects. Data collection was carried out using written tests and interviews. The research results obtained include factors that cause students to have difficulty understanding learning and solving problems in three-dimensional space material, namely students do not understand the concept of triangles, students' low interest in learning so that students become less attentive and lazy, do not understand the meaning of the questions, and students only memorize the concept, so they are given other questions and are confused

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

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
