Research Project Presentation by blu3mo §

• Presenter: Aoyama Kyotaro
• School: Gunma International Academy High School, 11th Grade (Junior Year)

Overview §

• Continuing the development of educational software currently in progress, focusing on researching pseudo-synchronous communication.

• Topics covered in the lecture by the Information Science Expert:

  • Utilizing discrete algorithms

Table of Contents §

• 🛠 About the ongoing development
• 📊 Connection with Information Science research

🛠 About the ongoing development §

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

  • Watching classroom videos on the screen

• 

• Concept

  • In a nutshell: “Eliminating the synchronicity of synchronous classes”

Synchronicity of Classes §

• 

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

• 

  • “Can’t ask nearby people questions.”
  • “Can’t discuss with other students.”
  • “Can’t ask questions to teachers/other students.”

Revisiting Synchronicity §

• ➡︎ Resolving trade-offs

Teacher ⇄ Student Interaction §

• Students can perform actions on real-time classroom videos such as

  • ▶️️ Play
  • ⏸ Pause
  • ⏪ Rewind 10 seconds

• ➡︎ Partially asynchronous interaction between teachers and students

• 

  • Aligning the speed of receiving information with the speed of understanding

Student ⇄ Student Interaction §

• No synchronization among students
• If there is no dialogue among students, the meaning of synchronous classes is lost
• ➡︎ Partially pseudo-synchronous interaction among students
  • Later students see messages from students ahead on the timeline
  • Since they are experiencing the same video, it can be considered pseudo-synchronous
  • 
• Medium of interaction: Writing on the video
  • Shared annotations
  • Example:
    • Writing down a different perspective on the class content
    • Remembering a good memorization method and writing it down

Connection with Information Science Research §

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

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

• Viewing pseudo-synchronous connections among students (one-way) as a directed graph

  • For n students, there are $2^n$ patterns per student
  • Applying the techniques introduced in the discrete algorithms course to identify the “optimal” connections

• What is an “optimal” connection?

  • Minimal time difference (synchronization possible with adjustments)
  • Valuable information for that student
  • Based on observations from user testing

• Pseudo-synchronous communication

  • An environment where constraints exist due to the flow of time, though not entirely synchronous
    • Environment for asynchronously re-experiencing videos, etc.
  • However, matching people in such dialog environments was not found in previous studies
    • Does this lack of prior research make it novel as a research point? #Information-Science-Expert
