Abstract

The motivation behind this investigation was the weak performance of children in math problems. The purpose of this study is to determine the impact of problem-based learning model on improving students' ability to solve mathematical problems. This study utilized a quasi-experiment method with a Nonequivalent Control Group design. The subjects in this study were class VII B as the experimental group and class VII C as the control group. Each of the two classes had thirty-five students.  The purpose of using a control group as a comparison is to observe what symptoms appear in the group of participants who receive treatment. The conclusion shows that the Problem Based Learning model has a significant impact on the average N-Gain score based on the variation between the pretest score and the final score, namely the posttest score, where the average N-Gain score of the experimental and control classes is significantly different.

Abstract

The Indonesian government adopted a new policy for the education system to improve the quality of education. One of the policies implemented is the elimination of the National Examination, which is a tool for assessing student learning outcomes at the end of each level of education against national standards. The National Examination was replaced with a Minimum Competency Assessment (AKM) and Character Survey. AKM focuses on students' abilities in reading and writing or known as literacy and numeracy. Numeracy literacy includes understanding mathematical concepts and the ability to apply these concepts in everyday life. Trigonometry material. This is an important topic in mathematics that involves the relationship between angles and side lengths of a triangle. Therefore, this research was conducted to analyze the numeracy literacy skills of class The research method used is descriptive qualitative research. The research results showed that the numeracy literacy skills of students in the low category were 40%, in the medium category were 47%, and in the high category were 13%.
