Mathematics Education Research is a field that studies how people learn and teach mathematics. It focuses on understanding the best practices for teaching math concepts, improving student engagement, and developing effective curricula. Researchers often analyze classroom interactions, teaching methods, and learning outcomes to identify what works best for different learners. This research also explores the challenges students face in understanding mathematics, including issues related to cognitive development and socio-cultural factors. By examining these elements, educators can create strategies that support diverse learners and promote a deeper understanding of mathematical concepts, ultimately enhancing overall math education.
