Key Points

The aim is to highlight the stagnation in math performance across various countries over the past two decades and propose effective strategies to address these issues.
Analyzed trends in math stagnation using PISA and TIMSS data from the past 12 to 20 years.
Included countries from English and German-speaking regions, most Latin American countries, and top Eastern Asian countries.
Provided evidence-based solutions through the MMU series.
Identified significant math stagnation across the studied countries over recent years.
Showed that Eastern Asian countries still outperform other regions in math education.
Proposed actionable evidence-based solutions that could lead to improvements in math skills.

Implication

Analysis shows math stagnation in English and Latin American countries, suggesting evidence-based solutions to improve outcomes.

Abstract

In this paper, the author visually demonstrate the math stagnations of almost all English, German -speaking countries, most Latin American countries, and the top 5 math Eastern Asian countries (the most recent) over the past 12 years (for PISA math) and 20 years (for TIMSS math) and provide the evidence -based solution that can overcome the math stagnations completely within
