Abstract

The aim of this study is to describe the mathematical reasoning ability of students at TSM major (Motorcycle Engineering) Darul Karomah Singosari on square root material. This study applies descriptive qualitative approach, data was collected using test instrument that has been tested on three research subjects, and analyzed using qualitative descriptive technique. The results show that low- ability (Kemampuan Rendah) subject is the student with less mathematical reasoning ability because the subject has not been able to solve the five existing indicators of mathematical reasoning, middle- ability (Kemampuan Sedang) subject include student with moderate mathematical reasoning ability (although the subject has not fulfilled the five indicators of mathematical reasoning requirements), this can be seen from his effort to make a mathematical assumption even though the conjecture made was not correct, and high- ability (Kemampuan Tinggi) subject refers to the student with high mathematical reasoning ability because he can fulfill two of the five indicators of mathematical reasoning.

Abstract

The research belongs to a qualitative descriptive study that aims to describe the numeracy literacy skills students grade 8 of State Junior High School of Kota Baru I (SMPN Kota Baru) in terms of their cognitive styles. The subjects of this study were eight students representing students with reflective cognitive styles yet impulsive cognitive styles. Data collection techniques were, matching familiar figure test (MFFT) to classify students based on their cognitive styles, numeracy literacy tests, and interviews. Data analysis techniques used were data reduction, data presentation, and drawing conclusions. The results of this study showed that the level of numeracy literacy skills of reflective students (SR) was respectively SR 1 is 88%, SR 2 is 67%, SR 3 is 79% and SR 4 is 91%. The level of numeracy literacy skills of impulsive students (SI) was respectively SI 1 is 58%, SI 2 is 67%, SI 3 is 50% and SI 4 is 63%. Reflective subjects have a category of high and very high numeracy literacy ability levels while impulsive subjects have a category of medium and high numeracy literacy ability levels. Reflective students need a long time to understand the problem by describing it into a mathematical model so that reflective students excel in the reasoning aspect. Impulsive students tend to be quick in answering questions but pay less attention to the right answers so that impulsive students stand out in the communication aspect.

Abstract

Every concept in mathematics is related to one another. In addition, a concept can be a prerequisite for another concept. Mastery of a concept is needed to learn other concepts. One of the materials that is an important foundation in mathematics is the linear equation. The material on linear equations is the basis for understanding more advanced mathematical concepts, such as geometry, statistics, and calculus. Therefore, a strong understanding of this material is very important for the junior high school level. Referring to information from subject teachers and students in the mathematics subject of linear equations for class VIII A, St. Aloysius Catholic Junior High School Niki-Niki explained that there are still many students in class VIII A who have learning outcomes that are below the criteria set by the school. So a solution is needed to solve the problems being experienced, one of which can be done is to carry out community service, namely providing training in the use of the Geogebra application which can significantly help students build an understanding of the concept of linear equations.
