I worked as an elementary school teacher for over 10 years. As I have met students in my classroom, I realized that technology can benefit students as well as teachers. Because I had a master's degree in elementary mathematics education, I started developing educational Apps for learning and teaching mathematics and broadening my territories.
Here are my projects.

Hologram Maker (2016)
Hologram Maker (2016)
What is light? It is hard to expect to listen to elementary students the right answers. From a view of STEM education, however, light is a very interesting subject that should be covered in that it can introduce a variety of concepts in physics. For elementary school students, making them play with "light" is the first step to learn about it. Here is where the hologram comes into play.
Using the pyramid that can be made by OHP film, this android app allows students to experience the hologram in a maneuverable manner. Students can make 3D text, 3D cube with their own pictures, 3D planets in our solar system as if they are real.

Educators and Social Media
How and why do educators use social media?
Social media allows educators to connect with colleagues beyond their local school contexts. Then, what are they discussing and sharing? Can social media benefit their professional learning? What are the potential or the perils? What implications can we find through our exploration?
To answer these questions, I am delving into Reddit, one of the largest social media platforms in the world. I prefer to use Python for data mining and NLP work (e.g., topic modeling and sentiment analysis).
