Case-Based Learning Model with MathCityMap to Improve Mathematical Literacy

Abstract

Mathematical literacy is a skill needed to support the current era. However, mathematical literacy in Indonesia is low, as evidenced by the results of PISA 2021 and previous relevant research. The Cased-Based Learning (CBL) model can be a solution to overcome the problem of mathematical literacy. Assisted by learning media using MathCityMap, it is alleged that it can simplify the learning process in the current era where technology is an important part of education. So, the purpose of this study is to find out the improvement of mathematical literacy using the MathCityMap-assisted CBL model. The results of the research obtained a value of t_stat=7,071 and t_(1-α,dk)=t_(1-0,05,(33+33-2))=t_0,95,64=1,997. Because 7,071>1,997 then t_stat>t_(1-α,dk). This means that H_0 rejected or accepted H_1. This means that the average increase in mathematical literacy in the MathCityMap-assisted CBL model is more than that of the conventional model. In addition, the math literacy gain value in the MathCityMap-assisted CBL model is 0.528 which is included in the medium category. In CBL learning, students are directed to solve cases related to daily life. Indirectly stimulating the development of students' mathematical literacy. So, the use of the MathCityMap-assisted CBL model can improve mathematical literacy.
