“…As researchers have noticed, the issues about values in mathematics education are rather complex (e.g., Hill et al, 2021), and this complexity is largely caused by the complexity of the concept of values itself. In fact, when people talk about "values" in mathematics education, what are valued can be mathematics, mathematics teaching and learning, and mathematics education as part of general education, and those who value can be students, teachers, curriculum developers, educational policy makers, government leaders, and the general public or the society, and moreover, values can be about the outcomes of teaching and learning or about their process.…”
