Abstract

This study aims to determine students' mathematical abstraction ability, answer process and difficulties faced by students in solving derivative problems. The subjects in this study were 11th grade students of SMA SWASTA AN - NIZAM Medan who were taught with the application of PBL model and scientific approach. The instrument in this study is a formative test used to see the level of mathematical abstraction ability and the answer process given by students. The difficulties faced by students in the process of solving the problems given can be known through the interview process conducted and documented through cell phones. Of the 19 students who took the math abstraction ability test, 4 students had high category math abstraction ability (21%). 11 students have medium category math abstraction ability (58%), and 4 students have low category math abstraction ability (21%). Of the 4 problems given, for the recognition stage, problem no 1 can be solved by all students. problem no 2 can be solved by 17 students, problem no 3 can be solved by 12 students and problem no 4 can be solved by 8 students. The decline also occurred at the representation and structural abstraction stages. After being analyzed based on the process of answers given by students and the results of interviews conducted, the decline was caused by: 1. the level of difficulty of the problem, 2. learning experience, 3. reasoning power and 4. literacy skills of each different student.. In this research, the media used to help the research process is geogebra. The use of this media is only limited to how to solve the problems given in other ways besides the concepts taught at school.Keywords: Qualitative Research Analysis; Mathematical Abstraction Ability; Problem Based Learning Model

Abstract

The aims of this research are: (1) To find out how mathematical literacy skills and critical thinking skills affect mathematical problem solving abilities simultaneously, (2) to find out how mathematical literacy skills and critical thinking skills affect mathematical problem solving abilities. part. This study used a quantitative research approach. This research was carried out at SMPS Bina Taruna Medan, SMPN 20 Medan and SMPN 33 Medan. The subjects of this research were students in class VII-1 in three schools totaling 90 students. The sampling method in this study was a random sampling technique. The instruments used consisted of: (1) a test of mathematical literacy skills, (2) a test of critical thinking skills, (3) a test of mathematical problem solving abilities. Data analysis was performed using multiple linear regression analysis. The results of the research show: (1) There is an influence of mathematical literacy skills and critical thinking skills on mathematical problem solving abilities simultaneously, (2) There is an influence of mathematical literacy skills and critical thinking skills on mathematical problem solving abilities. partial capability. (3) mathematical literacy skills and critical thinking skills have an influence of 90.1% on simultaneous mathematical problem solving abilities, while 9.9% is determined by other variables.
