Comment from Sakaide City Board of Education:
Sakaide City has decided to introduce Qubena, an AI-powered digital learning material, as a new initiative to foster solid academic abilities in students. Qubena is a learning support tool where AI analyzes each student's learning status and proficiency level and automatically presents individually optimized problems. By presenting optimal problems at optimal times according to students' proficiency levels, we believe it will promote proactive learning and efficient knowledge retention.
Furthermore, we will work on linking learning data, ensuring safety in collaboration with other municipalities, so that educational data surrounding learners can be effectively and safely utilized by the learners themselves.
