I started in September 2025 as PhD student in Mathematics Education. My project is about developing framework that help the design, implementation, and effectiveness of digital learning environments to enhance mathematics education. Through a design-based research approach and using history/socio-ecological of mathematics contexts, I aim to support engagement, meaningful and conceptual understanding where learners often do not see the purpose of what they are studying, nor do they understand how mathematical thinking has emerged from human needs, problem-solving, and creativity.
