Abstract

This study explores the integration of the history of mathematics and geometric approaches in enhancing students' understanding of quadratic equations. The research indicates that students who engage in this learning process can establish connections between geometric manipulations and algebraic symbols used in quadratic equations. By converting geometric forms into algebraic expressions and vice versa, students gain a deeper understanding of concepts such as factorization and perfect square solutions. The integration of historical mathematics and geometric approaches proves to be effective in improving students' conceptual understanding and overcoming learning barriers. Visualizations, particularly through methods Geometry, allow students to build a more intuitive understanding of quadratic equations, thereby increasing their interest and motivation in learning

Abstract

Educational game media developed based on problem-based learning is one alternative designed to help students improve their mathematical literacy skills and understand sequences and series in a more interesting and interactive way. This study aims to examine the validity, practicality, and effectiveness of using media in mathematics learning. The type of research used is development research with the ADDIE research model. This study was conducted at MAN 1 Medan with class X-16 as the subject. The results showed that the use of educational game learning media could improve the mathematical literacy skills of class X-16 students. This was indicated by the results of subject matter expert validation with a percentage of 88% in the ‘highly valid’ category, as well as media expert validation results with a percentage of 89.9% in the ‘highly valid’ category. In addition, the students' response to the media reached 88.4% and was categorised as ‘very practical’, which was also supported by the N-Gain results on the mathematical literacy skills of class X-16 students with a result of 0.710, which falls into the high category, meaning that the educational game media developed is effective for use in learning the material on sequences and series
