Peningkatan Kemampuan Penalaran Matematis dan Pemecahan Masalah Serta Analisis Self Efficacy Melalui Teams Games Tournamen Pendekatan Scientific Menggunakan E-Learning Kahoot

Abstract: Teams games Tournament to improve mathematical reasoning ability and problem-solving as well as self-efficacy student analysis. Mathematical reasoning and problem solving capabilities and self efficacy are important aspects that students need to be empowered to improve their learning outcomes. One of the efforts that can be taken to improve the aspect is through the implementation of appropriate methods of learning. Teams Games Tournament a scientific approach to using e-learning Media is an innovative learning method that allows students to perform various mathematics-based learning through interactive media based on Information technology. This method focuses the purpose of achieving the students ' ability to collect, identify and observe information, hypothesize, compile questions and process information and draw conclusions from problems that can be Solved. The results of research conducted with an experimental approach through the study of action of this class were analyzed using mixed methods. From the results of the analysis can be expressed that (1) There are differences in mathematical reasoning ability and problem solving as well as self efficacy students who have acquired TGT scientific e-learning Kahoot and TGT scientific and Conventional, (2) Mathematical and problem-solving capabilities and self efficacy students who have learned TGT scientific e-learning is better than students who get the study of TGT scientific and Conventional, (3) There are increasing Skills of mathematical reasoning students who acquire the learning of TGT scientific e-learning Kahoot and TGT scientific.
