Thanks to the GIGA School Concept, a 1:1 device environment has been established in elementary, junior high, and high schools nationwide, and learning utilizing iPads is becoming commonplace.
In this context, if 'Kakusel' were introduced to schools nationwide, how would students' learning change? This press release describes that future learning reform.
===============================
◆ Study Reform for Students with Kakusel Introduction to Schools
===============================
① Improvement of Basic Memorization Environment
(Image: Photos can be imported and memorized with a red sheet)
(1) Improvement during research-based learning on iPad
・Screenshot content of interest during class on the spot
・Save directly to Kakusel
・Review and memorize immediately when needed
→ "Summarizing later" disappears, leading to "learning on the spot."
(Image: PDF materials can be easily memorized. + Problem generation is also possible.)
(2) PDF learning changes from "reading" to "memorizing"
1. Students will be able to memorize PDF materials they are studying directly.
2. They will be able to check their understanding by automatically generating problems from PDFs (https://prtimes.jp/main/html/rd/p/000000016.000148831.html) to confirm what they have memorized.
→ PDFs will transform from mere documents into "memorization materials."
(Image: Excellent as a vocabulary app!)
(3) Improving study for students who struggle with paper-based memorization
Students can create their own vocabulary books, so if there's something they can't remember, they can immediately turn it into a memorization format. (For classical Japanese, social studies, science, and all other memorization.)
→ Towards a learning environment where "I can't remember" decreases.
② Improvements in English Learning
・Students will be able to quickly memorize junior high and high school English vocabulary using a vocabulary book.
・Simple English dictionary search will improve English search time and boost English learning efficiency.
(+ Searched English words can be directly incorporated into the vocabulary book for memorization.)
→ "Look up → Memorize" is no longer fragmented.
→ Learning speed significantly increases.
③ Breaking away from "just writing notes"
(Image: Convenient as an iPad study note app!)
Increased learning efficiency for students who take notes on iPad
By taking notes within the app and being able to memorize them directly, students can break away from "just writing notes" and "leaving them untouched."

===============================
◆ Spreading the Amazing Red Sheet Culture to the World
===============================
Red sheet learning is common in Japan, but it is not yet widespread overseas.
Red sheet learning can be said to be a unique Japanese culture.
The GIGA School Concept involves iPad learning, which is also a national policy. Wouldn't it be an interesting and newsworthy strategy to add Japan's unique learning method to this?
And by integrating this with Japan's "Cool Japan Strategy" and digital learning through the GIGA School, we can showcase this study method, leading to possibilities such as:
・Disseminating it as a learning style originating from Japan
・Creating new value in the education sector
・Gaining interest and re-evaluation from overseas
In this way, even when considering international connections, introducing a red sheet app is an interesting idea.
* Kakusel is released in the US under the name Red Sheet (https://apps.apple.com/app/id1580506756).
Furthermore, by intentionally viewing red sheet learning as a culture, wouldn't it be valid to introduce it from the perspective of cultural heritage?
Precisely because it is integrated with digital technology, it can be said to be a "good opportunity to re-excavate its value without feeling outdated."
===============================
◆ Finally
===============================
If Kakusel were introduced to schools nationwide, we believe the following changes would occur:
・Evolution of students' memorization environment
・Promotion of active student learning
・Improvement of student learning efficiency
・Dissemination as Japanese culture
We hope this future becomes a reality.
