Abstract

Mathematical representation ability is one of the important abilities of learning mathematics. This study aims to determine whether the increase in the mathematical representation ability of students who receive learning using GeoGebra is better than students who receive learning using ordinary learning. The research method used is a quasi-experimental method with the design form The Nonequivalent Pretest-Posttest Control Group Design. The population of this research is the students of class X SMK PGRI 1 Tourism Cianjur. Involving a sample of 31 students from two classes selected through purposive sampling technique. Class X Catering and Dressing as an experimental class and class X Banking as a control class. The instrument used is a test instrument in the form of pretest and posttest to measure the ability of mathematical representation and non-test in the form of an attitude scale questionnaire. Analysis of quantitative data in this study using SPSS 24. The results of the analysis show that the improvement of mathematical representation skills using GeoGebra is better than mathematical representation skills using ordinary learning. And students like the use of GeoGebra in learning mathematics.

Abstract

This study aims to analyze the relationship between learning motivation and mathematical communication skills in vocational high school students. The background of this study is the importance of mathematical communication in mathematics learning, as well as the low learning motivation of vocational high school students that impacts these abilities. The research method used is quantitative with a correlational approach. The population in this study were grade X students at SMK Negeri 1 Cipanas, with a sample of 26 students from grade X MPLB 3 selected using a purposive sampling technique. The instruments used included a learning motivation questionnaire and a mathematical communication ability essay test. The results showed that there was no positive and significant relationship between learning motivation and mathematical communication skills in vocational high school students. Based on these results, it can be interpreted that high learning motivation does not necessarily align with high mathematical communication skills. This means that even though students have a high learning drive, it does not automatically make them able to communicate mathematical ideas well. This finding implies that increasing learning motivation alone is not enough to improve students' mathematical communication skills. Mathematics learning needs to be designed not only to motivate students but also to specifically train mathematical communication skills such as explaining ideas, using symbols appropriately, and interpreting real-world situations into mathematical models.
