Educational Informatics Lab
Machine-translated · View original
The lab makes the learning process visible through learning logs and improves education with evidence.

AboutAbout the lab
Evidence and technology for every kind of learning.
The Educational Informatics Lab (Ogata Lab) aims to evolve education, which has long relied on intuition and experience, into education based on evidence and technology.
By making the learning process visible and capturing each student's understanding and stumbling points, the lab enables better lesson design and learning support. It also develops tools such as digital textbooks, learning dashboards, and platforms for schools.
Working with educational institutions, the lab is building an environment where anyone can learn effectively, anywhere.
Key terms
- Learning log
- Learning data that records how students read materials, where they spent their time, and what they focused on
- Learning analytics
- Research that collects and analyzes learning data and uses it to improve learning and teaching
- xAPI
- A mechanism for recording the activity of various learning tools in a common format
ResearchResearch themes
Using learning analytics, which draws on learning logs and data analysis, the lab improves education based on data from real classrooms.
*Illustrative imageVisualizing Learning Logs
By making visible the learning process that could not be seen before, the lab enables learners to reflect on their own learning and teachers to optimize their instruction.
*Illustrative imageEducational Support Tools and Learning Infrastructure
The lab develops and improves platforms for digital learning materials and tools that visualize learning interactions. It builds mechanisms that record and store logs in a common format using xAPI, and also works on comparing and analyzing logs across schools.
*Illustrative imageLearner Modeling and Empirical Studies
The lab builds models that capture how each student learns from their learning behavior, and uses them for feedback and automatic recommendation of learning materials. It also conducts empirical studies in which the tools and models it develops are kept in use in real school settings, and are repeatedly improved and evaluated.
