Stress Test Instructions

The purpose of this stress test is to insure server stability for our final assessment phase of VCAEST. During the VCAEST assessment we will potentially have 25 - 50 participants interacting with the VCAEST interface at a single time. 6 different "instances" will be established prior to the final assessment. Each instance allows 6 users to interact with the interface at a time. We will not need to stress test the virtual world component of the VCAEST interface. We will, however, need to stress test AutoTutor Lite. AutoTutor Lite is the web-based intelligent tutoring system that has been integrated inside the VCAEST virtual world.

The more the merrier -- ideally we'll have 10+ people interacting with a single SKO (Sharable Knowledge Object) or an individual AutoTutor Lite module. 

Before the official stress test begins, a few things need to be recorded. 
  1. Have one user run through the SKOs that will be tested and note the time it takes to complete the information delivery portion. 
  2. Have one user run through the self-reflection portion of a module and note the average time it takes to receive feedback from the Tutor. About 3-6 seconds is the current average. This changes depending on the size of the Tutor utterance. 

For the stress-testing: Information Delivery & Self-Reflection
  1. Note the time before beginning. 
  2. Have all users open up this SKO: http://www.x-in-y.com/sko2013/VCAEST/ATL.html?guid=18e38ca4-f95c-4384-b22a-f50c79f39752&skoserver=http://skodev2012.appspot.com&DSSPP=http://dsspp2011.appspot.com. It took me 8 min and 35 sec to get through all of the information delivery. 
  3. Have each user note the time when they reached slide 35/36. The Tutor will ask the users to click on the right arrow to advance to the Self-Reflection assessment.
  4. Have all of the users interact in the self-reflection at the same time. 
  5. Have the users note the delay between input and feedback. It should be about 3 - 6 seconds. 
For the stress-testing: Tutoring Assessment
  1. Note the time before beginning.
  2. Have all users open up this SKO: http://www.x-in-y.com/SKO2013/VCAEST/ATL.html?guid=8e69f0bc-91df-4ca1-805e-acc11d3f0046&skoserver=http://skodev2012.appspot.com&DSSPP=http://dsspp2011.appspot.com 
  3. Here are the following answers/input the users should type in: 

    Expectation 1: National Response Framework is a national system that describes how to utilize key response principles and lays groundwork for a united national response. Unique situations in which Federal Government takes on a larger role to provide states with support.

    Expectation 2: 
    Incident Command System (ICS) is a function of NRF, at lowest level. Used on site at beginning of incident. Builds upon itself with layers. As it grows it looks different, but is still a part of NRF.

    Expectation 3: Key principles are basis for how entities should operate in response to an incident. Emphasize communication, chains of action, adaptability, unity, and preparedness.

    Expectation 4: Stafford Act brings Federal resources and funding to support states during major disaster situations in an orderly and systematic way. Requires governors request assistance before president can send aid.

  4. The users are free to type in their own input (I don't know. Please help me., etc), but the above input should guarantee Tutor feedback.
  5. Note the time delay from the input and feedback. The delay here will be a little bit longer than the delay for the Self-Reflection feedback.
