(/blu3mo/Information Science Expert) Research Project Presentation

• 🙋‍♂️ Shintaro Aoyama
• 🏫 Gunma International Academy High School 11th Grade (Sophomore)

Summary

• Continuation of development of educational software and research on pseudo-synchronous communication

• Learned in the Information Science Expert lecture:

  • Utilization of discrete algorithms

Table of Contents

• 🛠 About the development
• 📊 Connection to information science research

🛠 About the development

• Used as an iPad app for real-time classroom attendance

  • Watch the class video on the screen

• 

• Concept

  • In one sentence: “Resolving the synchronicity of synchronous classes”

Synchronicity of classes

• 

  • “I want to hear the current topic again.”
  • “I want to see this movement in slow motion.”
  • “I want to pause for a moment to think on my own.”

• 

  • “I can’t ask questions to nearby people.”
  • “I can’t discuss with other students.”
  • “I can’t ask questions to the teacher/other students.”

Summary

• Teacher ⇄ Student
• Student ⇄ Student
• Rethinking synchronicity
• ➡︎ Resolving the trade-off

Teacher ⇄ Student

• Students can perform operations such as

  • ▶️️ Play
  • ⏸ Pause
  • ⏪ Rewind 10 seconds

• on the real-time class video

• ➡︎ Some interactions between teachers and students are asynchronous

• 

  • Aligning the speed of receiving information and understanding it

Student ⇄ Student

• No synchronicity between students
• If there is no interaction between students, synchronous classes lose their meaning
• ➡︎ Some interactions between students are pseudo-synchronous
  • Later students can see messages from students who are ahead of them on the timeline
  • Since they are experiencing the same video, it can be considered pseudo-synchronous
  • 
• Medium for interaction: Writing on the video
  • Writing is shared
  • Examples:
    • Writing alternative interpretations of the class content
    • Writing down a good memorization method that came to mind

Conclusion

• Asynchronously
• Pseudo-synchronously

📊 Connection to information science research

• Connecting all students in a large group leads to information overload

  • Need to select which students to connect with pseudo-synchronously
  • 

• Understanding the pseudo-synchronous connections between students as a directed graph

  • For n students, there are $2^n$ patterns for each student
  • Applying the techniques introduced in the discrete algorithm course to the problem of selecting the “optimal” connections

• What is the “optimal” connection

  • Small time difference (synchronization is possible with adjustments)
  • Information that is valuable to that student
  • Based on observations from user testing

• Pseudo-synchronous communication

  • An environment that has constraints due to the flow of time, although not completely synchronous
    • An environment where videos, etc. are experienced asynchronously
  • However, no previous research has been found that matches people in such a dialogue environment
    • Does this point provide novelty as a research topic? #Information Science Expert
