SNA Tasks

Social Network Analysis Tasks

Goals

• Integrate SNA to assess social interaction in lesson discussion community

Summary

• Monday: Submit data entry in Excel/Google Sheet format
• Wednesday: Receive SNA social graphs and metrics form the instructors
• Friday: Submit the reflection & report

Read: (as early as possible to obtain good understanding on SNA)

• See Lesson 2 KEY 2 discussion question.
• Tutorial for Network Weaving by Dr. Aras Bozkurt (PowerPoint; Show you how to add data to spreadsheet)
• Optional:
  • Behavior identification on a Connectivist Rhizomatic learning network, by Bozkurt, Aras.

Data Entry (Monday): Complete by Monday after the lesson discussion completed

• Use Excel or Google Sheet to enter the SNA data
• Sample entry: Google Sheet or Excel
  • IMPORTANT: When you conduct data entry, be sure to enter students' Nabble names consistently.
    • EX: "Chih Tu" not "Chih_Tu" "Chih-Tu" nor "Chih"
    • If you input the students with different names, our SNA won't be accurate at all.
    • You can use to view the classmates' Nabble usernames.

• You do not need to order your data entry by name or post date/time etc. It doesn't matter when I conduct SNA on NodeXL.
• Share it with Drs. Chih Tu (ct68@nau.edu) & Aras Bozkurt (arasbozkurt@gmail.com)
  • We will run SNA on NodeXL Pro for you to prepare the report and the reflection.
• Optional Video Resources:
  • SNA & NodeXL Pro 1
  • SNA & NodeXL Pro 2
  • SNA & NodeXL Pro 3
  • SNA & NodeXL Pro 4

Receive (Wednesday): SNA social graphs and metrics from Drs. Chih Tu & Aras Bozkurt by Wednesday

Complete (Friday): SNA report & reflection by Friday

• Use SNA Report & Reflection Template
  • Review template
  • Download template
  • File name: EX: ETC655-Fall-2017-SNA Report-Group-X
  • Length: 1,500-2,000 words (Use Word Count feature to check the length; Tools>Word Count)
• Share the SNA Report & Reflect with Drs. Chih Tu (ct68@nau.edu) & Aras Bozkurt (arasbozkurt@gmail.com)
• Your group will receive the results that include:
  • A spreadsheet
  • A few social graphs
  • Download a copy for your own references
• SNA results: Spreadsheet
  • Look for "VERTICES-NODES" tab
  • Focus your report and reflections on the columns of "In-Degree," "Out-Degree," & "Betweenness Centrality."
  • Calculate the Mean and Standard Deviation for each column to help you to interpret.
  • In-degree show the numbers of communication ones receive while out-degree represents communication they make to others.
  • Betweenness centrality denotes the extent to which a participate lies between others in their network (class community). It is a measure of the potential influence arising from their positions within the network through both direct and indirect pathways.

• SNA results: Social Graphs
  • Use different social graphs to help you to interpret.
  • The social graphs may look like this:
