Numerical literacy in mathematical problem solving: A brief literature review.

An important study was conducted to investigate the effectiveness, as well as the impact of various approaches used in developing numeracy literacy from elementary school to university. Therefore, it is necessary to conduct a systematic review of numeracy literacy. This review synthesizes findings from existing research of various approaches used to investigate numeracy literacy between 2017-2021. Obtained 12 titles from the results of quantitative and qualitative research. The research method chosen in this study is the SLR (Systematic Literature Review) method. The results of the research on the causes of the low numeracy literacy of students, how to grow students' numeracy literacy skills, and the difficulties experienced by students in solving problems in terms of numeracy literacy skills. Suggestions from the results of this systematic literature review are to recommend ways so that students are able to convey information well, and numerical literacy skills need to be given a stimulus to encourage students' curiosity. The highest effect size is 0.42 in the medium category, this result is obtained from research with the theme of increasing school literacy and numeracy literacy through blended learning models, the use of blended learning models has a more effective effect on numeracy literacy skills.
