Abstract

ABSTRACTLearning mathematics is considered difficult material by students from elementary school to high school. Based on the results of observations made through interviews with Mathematics teachers, it was found that the problems experienced by students at SMAN 1 Sewon Bantul were found. The problems experienced by students are related to three dimensions and geometry transformation materials. In addition, there are still many students who cannot understand and visualize geometry material. How to make it easier to learn and understand abstract mathematics, especially geometry material, requires learning media, namely mathematics software. In learning mathematics, students need technology-based media that can represent their intuition in understanding a mathematical concept. The purpose of this service is to socialize GeoGebra Android as an open-source application to visualize geometry learning very accurately and more easily for high school students. The method used in this service activity is a training method through lectures, discussions, demonstrations, and assignments. With the use of applications in learning, it is expected to increase students' motivation and understanding in learning mathematics, especially geometry material. The results of the questionnaire from 24 respondents of class XII IPA 6 students obtained a percentage that as much as 72.7% agreed that learning using geogebra was very interesting and interactive in learning geometry material. Keywords: GeoGebra, geometry, training, math learning. ABSTRAKPembelajaran matematika dianggap materi yang sulit bagi para siswa. Didasari dari hasil observasi yang sudah dilakukan melalui wawancara bersama guru mata pelajaran Matematika ditemukan permasalahan yang dialami siswa di SMAN 1 Sewon Bantul. Permasalahan yang dialami oleh siswa yaitu terkait dimensi tiga dan materi transformasi geometri. Selain itu, siswa belum dapat memahami dan menvisualisasikan materi geometri. Cara mempermudah belajar dan memahami matematika yang abstrak khususnya materi geometri diperlukan media pembelajaran yaitu software matematika. Dengan demikian pada pembelajaran matematika, diperlukan suatu media berbasis teknologi yang dapat membantu siswa dalam memahami konsep matematika. Sehingga tujuan dari pengabdian untuk mensosialisasikan GeoGebra Android sebagai aplikasi open source untuk memvisualisasikan pembelajaran geometri dengan sangat akurat dan lebih mudah bagi siswa SMA. Metode yang digunakan dalam kegiatan pengabdian ini adalah metode pelatihan melalui ceramah, diskusi, demonstrasi, dan penugasan. Dengan penggunaan aplikasi dalam pembelajaran diharapkan dapat meningkatkan motivasi dan pemahaman siswa dalam pembelajaran matematika khususnya materi geometri. Hasil angket dari 24 responden siswa kelas XII IPA 6 didapatkan prosentase bahwa sebanyak 72,7% menyatakan setuju bahwa pembelajaran menggunakan geogebra sangat menarik dan interaktif dalam pembelajaran materi geometri.Kata Kunci: GeoGebra, geometri, pelatihan, pembelajaran matematika

Abstract

Learning is an activity that is arranged in a planned and systematic manner by involving information and the environment to facilitate students in learning. Efforts that can be made by schools to continue to achieve learning goals during the pandemic, one of which is by implementing limited face-to-face learning. Limited face-to-face learning is learning that implements the Covid-19 prevention process and pays attention to the preparations made by schools before the start of learning, to ensure that learning takes place safely, clearly determining the number of days and hours for the division of limited study groups to be carried out. To see the success of learning mathematics during the learning process. It takes one of the use of learning media that is fun for students. Thus, to overcome this problem, researchers chose to use online-based learning media, namely Kahoot. Kahoot can be accessed at www.kahoot.com which is connected to the internet. During the evaluation at the end of the lesson using the Kahoot application, it can keep students excited and not watching during the learning process. Thus, the purpose of this study is to find out how the use of kahoot learning media in the face-to-face learning process is limited to learning mathematics. While the instruments used in this study were tests, questionnaires and observations. The test questions used in the use of the Kahoot application are 5 questions for each quiz that is carried out 3 times. The test given to students is in the form of multiple-choice questions on the class VII integer material. The questionnaire in this study was in the form of closed questions or statements, aiming to find out the student's response to the evaluation tool that would be given.

Abstract

The objective is to provide knowledge for pure mathematics and mathematics education students to understand quantified statements so that they can easily comprehend the meaning of mathematical propositions and facilitate their proof. The method used in this research is a literature review by collecting various sources such as books or scientific writings related to the logic used to understand mathematics, specifically related to quantifiers, both universal and existential quantifiers. When mathematics and mathematics education students understand the quantified statement ∀x[Px], what they do is take any (cannot choose specific) x, and it must be proven that x satisfies property P. Then, to understand the quantified statement ∃x[Px], what is done is to choose (at least one) x, and it must be proven that x satisfies property P. When mathematics and mathematics education students understand the multi-quantifier statement ∀x∃y[P(x,y)], what is done is to take any (cannot choose specific) x, then find (at least one) y (depending on x), and x, y must satisfy property P. Then, to understand the multi-quantifier statement ∃y ∀x[P(x,y)] or ∃y [P(x,y)∀x], what is done is to choose y (independent of x) and it must be proven that y satisfies property P along with all x.
