Abstract

The purpose of this study was to determine the difficulties of students in solving the problem of mathematical reasoning abilities in the material pattern number. The method used in this study is descriptive qualitative which aims to describe students' difficulties in completing the number pattern material based on their mathematical reasoning ability. To obtain the research data, the instrument is used in the form of tests of mathematical reasoning abilities in the form of description tests and interviews. The place of research was carried out at Al-Barry Mts Cikalongwetan. The population in this study were all students of Al-Barry Mts who skipped a row, and the sample was the eighth grade students of Al-Barry's Mts in a row. Based on the analysis of the data obtained conclusions: 1) students have difficulty in determining the pattern on the question, 2) students have difficulty in formulating generalizations of regularity / pattern numbers, 3) students are too focused on the formula.

Abstract

This study aims to determine the effect of the application of geogebra in the material tangent circles on student interest in learning. This study uses a qualitative descriptive method that aims to describe the level of student interest in learning using geogebra applications on tangent circles. The results of this study were obtained from the distribution of instruments in the form of questionnaires for student interest in learning which were then processed using a Likert scale and then analyzed. The place of this research was conducted at SMAN I Cikalongwetan. The population used was all students of SMAN 1 Cikalongwetan with the sample being students of class XI A of SMAN 1 Cikalongwetan. Based on the results of the analysis of the data obtained it can be concluded that the level of student interest in learning after learning to use geogebra can be categorized quite well and students look more enthusiastic when learning to use geogebra. The weaknesses of the application of geogebra in learning in schools are: 1) the limitations of tools / android, 2) the time used is longer because they have to introduce the functions contained in every tool in geogebra, 3) not all students like technology
