Abstract

The problem in this study is the low ability of students to solve mathematical problems. To solve this problem, the researchers used the ARIAS model. As for the purpose of this study is to improve students' mathematical problem-solving abilities, increase student activity, improve teacher teaching abilities through the ARIAS learning model. This type of research is classroom action research. The results of the research the problem-solving ability of the first cycle was 56% and 88% in the second cycle increased by 32%. The level of student activity towards mathematics increased, this was obtained by a percentage of 62% in cycle I, and 85% in cycle II increased by 23%. The teacher's ability to manage to learn was 56% in cycle I and 94% in cycle II, with an increase of 38%. The author concluded that students 'mathematical problem-solving abilities, student learning activities, and teachers' ability to manage learning increased in class X MIA-1 SMA Negeri 1 Padang Bolak.

Abstract

This study aims to determine the effectiveness of the role of ethnomatematics based on traditional crank game in increasing the ability of students to understand mathematical concepts at SD Muhammadiyah Sipirok and their responses to learning. This type of research is qualitative research. The learning model developed is a type of traditional game where elementary school students will be more enthusiastic about learning mathematics, especially in flat shape material where the concepts used will improve students' understanding of mathematical concepts. From the results of the analysis of observations during the learning process and the results of interviews conducted by comparing the tcount and ttable values ​​that the calculated value is greater than the table value and the results of the questionnaire students' responses to learning with the use of ethnomatematics based on traditional crank games are already in the very happy category because each None of the students scored 30 below or obtained half the expected maximum score of 60 where all students were above 30. The results of the research will be the type of flat shape in the crank game, the problem of the suitability of the crank game with the flat shape material and its understanding, the flat shape is used as contextual learning.

Abstract

The low ability of students to solve mathematical problems is one of the causes of the low student achievement in mathematics. There are many factors that cause this to happen, one of which is learning mathematics which is monotonous or lacks variation. For that, learning mathematics using IT during the teaching and learning process, in this case the Geogebra application. As one of the efforts made, of course, it is expected to improve students' mathematical problem solving abilities. Therefore, this study aims to determine whether the geogebra software can improve students' mathematical problem solving skills in the SPLDV material. The sample in this study were 35 students of class X IIS 1 in SMA Negeri 1 Batang Angkola with virtual research and using a qualitative approach.
