The lab builds new education and learning environments using information systems and AI.

AboutAbout the lab
A theory-oriented, field-first science of future education and learning environments
The Takagi Lab identifies problems in educational and learning settings and researches new learning methods and information systems to solve them.
It also works on designing and building new education and learning environments that use technologies such as AI and IoT.
Student research topics include supporting question-creation learning with generative AI and systems that help learners reflect on their learning.
Research topics are decided with students' wishes as the first priority.

*Illustrative imageA system for collaborative question creation by learners
This is a learning support system that uses ICT so that learners can create questions on their own initiative. Associate Professor Takagi developed it as an undergraduate, and Soka University now operates it. Learners and teachers can comment on the questions that are created, and learners compete for points, which encourages voluntary learning.
*Illustrative imageQuestion-creation learning and thinking, judgment, and expression skills
To clarify the learning effects of question-creation learning, the lab analyzes the relationship between question-creation learning and thinking, judgment, and expression skills. It does so using an original rubric it created to measure these skills.
*Illustrative imageNext-generation support system for question-creation learning
Through question-creation learning, in which learners deepen their learning by creating questions themselves, the lab aims to build a learning environment where learners can proactively improve their thinking, judgment, and expression skills. With use in computerized adaptive testing in mind, it is also building an item pool, a collection of questions whose difficulty and discrimination are known.
*Illustrative imageAutomatic question generation system
To reduce the burden of creating questions for certification exams, the lab proposed a question-creation support system that uses questions automatically generated from past exam questions. It extracts the knowledge contained in past exam questions to build a knowledge base.
