The most pressing challenge I face today in the field of education is the lag in the optimization of individualized learning. This problem strikes at the heart of education, which is to provide effective learning for all students. Traditional teaching methods often follow a one-size-fits-all approach that assumes homogeneous learning speeds and styles. This outdated model fails to address the diversity of student needs, backgrounds, and learning abilities. The importance of addressing this challenge cannot be overstated. Diverse learning needs stem from a variety of factors, including socioeconomic backgrounds, cultural differences, and unique cognitive profiles. In particular, students with developmental and learning needs, as well as those facing challenges such as truancy, require tailored educational strategies that recognize their individual strengths and weaknesses. However, the prevailing educational model largely ignores these needs, resulting in a gap between potential and achievement. The need for innovation in personalized learning is further emphasized by the evolving global context in which education is a key determinant of future success and contribution to society. Current uniform educational approaches (in Japan) are not suited to prepare students for the complexities of modern society and undermine their ability to solve complex problems, adapt to new situations, and think critically. The delay in the optimization of individualized learning is a serious hurdle that needs to be addressed immediately. Addressing this issue is not simply about improving academic outcomes, but about fundamentally rethinking how education can be more inclusive, adaptive, and supportive of each student's unique journey. By focusing on this issue, I can contribute to a more equitable, dynamic, and effective learner-centered education system that truly prepares all learners for the challenges and opportunities of the future.
