Abstract

This Research aims toanalyze the influece of the learning environment on the mathematics learning achievent of class VIIIA students at Karuni Christian Middle School. The learning environment in question includes physical, social, psychological aspects, as well as the learning methods applied. The research medhod used is a quantitative approach with data collection techniques through quesrionnaires and documentationnof students’ UAS scores. The research sample consisted of 27 students, research time was the even semester of the 2024/2025 academic year. Data analysis was carried out using descriptive statstics, simple linear regression tests, and pearson correlation tests eith the help of the SPSS aplication. Thr resarch results show that students’ perceptions of the learning environment are classified as good with an average score of 4.29 (scale 1-5). The average student mathematics achievement score was 74.69. the pirso correlation test shows that there is a positive and significant relationship between the learning environment anf mathematics learning schievement with a correlation coefficient (r)= 0.65 and significant (p)= 0.001. This means that the higher the mathematics learning achievement achievend.

Abstract

This study aims to identify the types of errors made by students in solving quadratic equations and analyze the factors that cause them. The research method used is descriptive qualitative with data collection techniques through written tests, interviews, and documentation. The research subjects consisted of 11 students in class IXB of SMP Negeri 1 Loura with instruments in the form of test questions and interview guidelines. The results of the study show that reading errors accounted for 45.45%, characterized by inaccuracies in making assumptions. Errors in understanding the questions also accounted for 45.45%, because students did not write down the known and asked information completely. Question transformation errors reached 81.81%, where students were inaccurate in writing down the mathematical model or did not write it down at all. Process skill errors also accounted for 81.81%, characterized by incorrect calculations and incomplete work. At the stage of writing the final answer, all students (100%) did not write the conclusion or answer correctly. These findings indicate that the dominant errors were in question transformation, process skills, and writing the final answer. The main factors causing these errors were a lack of conceptual understanding, lack of focus, and low accuracy among students. Therefore, a learning strategy that emphasizes understanding the concept of quadratic equations and accustoming students to writing down the steps to solve the problem in sequence is needed.

Abstract

Belajar matematika sangat penting bagi anak usia sekolah dasar (Cornelius dalam Abdurahman, 2003: 253), oleh karena itu perlu dilakukan suatu perencanaan dan perbaikan cara belajar yang dapat meningkatkan pemahaman bagi anak usia sekolah dasar berdasarkan kebutuhan belajar mereka. Di Desa Wali Ate masih banyak anak usia sekolah dasar yang mengalami kesulitan dalam mempelajari matematika khususnya pada materi operasi bilangan bulat, operasi bilangan desimal dan operasi pada bilangan Pecahan (bilangan rasional). Berdasarkan masalah di atas, maka perlu dilakukan pembelajaran berhitung bilangan bulat, bilangan desimal dan bilangan pecahan. Tujuan dari kegiatan pengabdian ini adalah untuk meningkatkan pemahaman konsep operasi pada bilangan bulat, bilangan desimal dan bilangan pecahan bagi anak usia Sekolah Dasar di desa Wali Ate. Adapun Tahapan awal yang akan dilakukan adalah pemberian pretets. Setelah pemberian pretes, selanjutnya diberikan perlakuan yaitu pengajaran operasi bilangan bulat, operasi pada bilangan desimal dan bilangan pecahan (bilangan desimal) dan selanjutnya pemberian posttest. Berdasarkan hasil posttest di atas, terlihat bahwa terdapat peningkatan kemampuan pemahaman berhitung pada anak usia sekolah dasar di desa Wali Ate. Dari hasil pretest dan posttest tersebut, dapat menunjukkan bahwa kegiatan pembelajaran ini memberi manfaat yang baik bagi anak-anak usia sekolah dasar di desa Wali Ate dalam memahami materi tentang perhitungan dasar.

Abstract

TPA is a test that is often used in job searches by both government and private companies. The Mathematics Education Study Program at Weetebula Catholic University needs to prepare and equip its alumnae and prospective alumnae to be able to compete in the world of work. The TPA question categories used in this training are the verbal category, the number sequence pattern category, the Venn diagram category, the proposition logic category, the analytical logic category and the mathematical reasoning category. This training was carried out using lecture and discussion methods. Before carrying out the activity, a pretest is carried out first. Meanwhile, at the end of the activity, a posttest was carried out. The average value of the pretest results for the verbal category is 40.74, the average value for the Number Patterns category is 51.11, the average value for the Venn diagram category is 48.89, the average value for the prepositional logic category is 33 .33, the average value for the analytical logic category is 35.55 and the average value for the mathematical reasoning category is 53.33. Meanwhile, the average value of the posttest results for the verbal category is 66.67, the average value for the Number Patterns category is 66.67, the average value for the Venn diagram category is 73.33, the average value for the prepositional logic category is 73.33, the average score for the analytical logic category is 70 and the average score for the mathematical reasoning category is 76.67.

Abstract

The problem in Wee Kura Village is that elementary school age children consider mathematics to be one of the most difficult subjects. Many elementary school age children are afraid of mathematics. One approach that can be used in learning mathematics is PMRI using the Dragon Ball Learning Model. The aim of this community service is to increase the understanding of elementary school age children through the PMRI approach using the Dragon Ball learning model. It is hoped that this community service activity will be able to overcome the problems of elementary school age children. Methods for carrying out activities include observation, preparation of service instruments, implementation of mathematics learning, evaluation and reporting. Learning activities are carried out outside school hours. The pretest results obtained the highest score of 75 and the lowest score of 45, while the average score was 60. For the posttest score, the highest score was 100 and the lowest score was 70, while the average score was 85. There was an increase in understanding abilities for elementary school age children. The interview results show that children are enthusiastic about learning mathematics, they can learn mathematics with fun approaches and method

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
