Abstract

STRENGTHENING TEACHER PEDAGOGICAL COMPETENCIES THROUGH THE USE OF DYNAMIC GEOMETRY SOFTWARE IN MATHEMATICS LEARNING. The selection of strategies, methods, models, and media of appropriate mathematics learning is a form of implementation of a teacher's pedagogical competence. In the 2013 curriculum, the teacher not only sets a scientific approach as a reference in implementing the learning process but also demands innovation to accommodate the right media as well. The role of instructional media, especially dynamic media, is very important in learning mathematics in both elementary and junior high schools. The media was used to explain abstract mathematical problems to be concrete, motivate students, stimulate student learning activities, and help the effectiveness of the learning process. Technological devices such as computers are one of the tools that can be used as dynamic mathematics learning media. Mathematical learning collaboration with ICT devices has been widely carried out in urban and rural areas in Indonesia. Dynamic Geometry Software (DGS) in the form of GeoGebra is a learning medium specifically developed to facilitate the learning of geometry, algebra, and calculus. Therefore, this community service activity (PkM) is intended to strengthen the teacher's pedagogical competence through the use of dynamic learning media using Dynamic Geometry Software (DGS) in the form of GeoGebra in mathematics learning in junior high schools. This PkM aims to train teachers to be able to operate or create mathematics learning media assisted by DGS, especially in learning geometry to students. By making their own, teachers can add insight and increase creativity in making learning media. The supported subjects in these community service activities were junior high school mathematics teachers in Ruteng City. As for the results obtained after the PKM activities, the teachers can operate and create mathematics learning media using DGS in the form of GeoGebra.

Abstract

Prestasi belajar matematika merupakan istilah yang berhubungan dengan pencapaian hasil belajar yang ditandai dengan penguasaan materi setelah mengikuti pembelajaran. Prestasi belajar matematika siswa pun beragam, dari yang tinggi sampai yang rendah. Berdasarkan fakta-fakta yang ditemukan di lapangan, peneliti berhipotesis bahwa faktor yang mempengaruhi atau yang melatarbelakangi masalah rendahnya prestasi belajar siswa adalah faktor inteligensi dengan indikatornya terletak pada tingkat kemampuan numerik siswa. Penelitian ini bertujuan untuk mengetahui apakah terdapat hubungan yang positif dan signifikan antara kemampuan numerik dengan prestasi belajar matematika siswa. Populasi dalam penelitian ini sebanyak 647 orang siswa kelas XI APH SMK Sadar Wisata Ruteng. Pemilihan sampel dilakukan dengan menggunakan teknik proporsional random sampling. Jumlah anggota sampel keseluruhannya adalah 87 siswa. Data kemampuan numerik dan data prestasi belajar matematika siswa dikumpulkan menggunakan metode tes. Hipotesis penelitian diuji dengan menggunakan teknik analisis korelasi. Hasil analisis data dari penelitian ini memberikan nilai koefisien korelasi sebesar 0,612 dan nilai thitung= 7,135 lebih besar dari ttabel= 1,6629 (7,135>1,6629). Selanjutnya Hasil analisis uji signifikan diperoleh nilai thitung = 7,135, sedangkan nilai ttabel = 1,663 pada taraf signifikansi (α) = 0,05 dan dk = n-2 = 87-2= 85. Ternyatayaitu 7,135 > 1,663. Dari hasil analisis ini dapat disimpulkan bahwa ada hubungan yang positif dan signifikan antara kemampuan numerik dengan prestasi belajar matematika siswa, artinya semakin tinggi kemamuan numerik seseorang maka prestasi belajarnya pun semakin baik. Begitupun sebaliknya. Dari hasil analisis juga diperoleh informasi bahwa besarnya sumbangan atau kontribusi kemampuan numerikterhadap prestasi belajar matematikaadalah 37,46%, sedangkan sisanya 62,54% dijelaskan oleh variabel lain yang tidak diteliti.

Abstract

Geometry is one of the critical subjects of mathematics. It includes concepts as points, lines, planes, space and their relations. Representations of three-dimensional objects using two-dimensional diagrams bring the difficulties of identification of their properties. The subfactors of spatial ability were identified as the primary variables in the performances of students related to geometry subject. The purpose of this study is to investigate the relationship between spatial visualisation and spatial orientation to the students understanding of space geometry concepts matter of the eighth-grade students. There are 60 eighth grade students as a sample of the study. The reliability and the validity studies of the tests were carried out In the first part of the study. In the second part, correlation and regression analyses were carried out. Significant correlations were found between each factor. For clarifying the relationships between more than one-factor multiple regression analyses were used. The results showed that the two predictor variables explained the 65,61 % of the variance in plane geometry test scores. However, a degree of contribution of each factor differed. The relative impact of spatial orientation ability (B=. 55) was higher than the spatial visualisation ability (B=. 28).

Abstract

Problem-posing ability is the ability to make and solve math problems. This research is qualitative research that aims to describe the ability to submit questions about prospective elementary school teachers concerning mathematical disposition. The subject of this research is the students of prospective school level teachers in the 6th semester, amounting to 3 people. The results of this study are (1) prospective primary school teachers with a high mathematical disposition can submit questions based on the information given related to addition and subtraction of ordinary and mixed fractions, the problem presented are in accordance material with moderate difficulty level, able to solve the problems posed with using a good language structure, (2) prospective primary school teacher with a moderate mathematical disposition level can form a story question based on additional information and subtraction of ordinary fractions, the questions submitted are in accordance material with a relatively low difficulty level and using a good language structure. However, unable to solve the problems raised, and (3) prospective primary school teachers with a low mathematical disposition level are not able to ask questions based on the two information provided. The prospective teacher has difficulty making a story question. These conditions have an impact on not fulfilling several other criteria, among others, conformity with the material, answers to the problems raised, language structure and the difficulty level of the question. The results of the study provide recommendations for policymakers on campus to help prospective students of elementary school teachers to develop problem-posing ability according to the level of mathematical disposition.
