Abstract

The purpose of this study was to describe the mathematical reasoning abilities of students and examine errors in solving system problems of two variable linear equations in class VIII by categorizing students with low, medium and high mathematical reasoning abilities. The research method used is a qualitative descriptive method with a form of test research. The population taken is all private junior high school students in Bandung Regency with a sample of selected VIII-A class students in 30 students of Sulaiman Air Force Middle School. The test instrument provided is in the form of 5 questions. The results showed that reasoning ability in the material system of linear equations was two variables, namely for male students mathematical reasoning ability only reached 57% and in female students mathematical reasoning ability reached 63% of 30 students, so that students' mathematical reasoning ability in class VIII- A Suludan Air Base Space Middle School is male students have lower mathematical reasoning ability compared to female students

Abstract

In this study the authors analyzed the difficulties of students in the process of the ability of mathematical creative thinking skills and to determine student learning interest in each item statement. Based on the analysis, for the material the straight Equation error made by students in working on creative thinking questions is the mastery of the concept of the material resulting in 67.63% of 34 creative students. The question instrument used is a question that has been tested for reliability, validity, differential power and difficulty index has also been validated by an expert validator. The interest in studying junior high school students is only reaching 59.20% in straight line equations. The indicator of student interest in learning gained the smallest percentage of 56.09% so that it influenced other indicators. The research method uses descriptive qualitative analysis to find out in depth the achievement of indicators of creative thinking skills and mathematical learning interest in each item statement. Based on the results of the overall research that the achievement of indicators of the ability to think creatively and the learning interest of students is still low.
