== COSMOS Education Toolkit ==
=== Summary ===
The rapid evolution of technology requires major transformation in the educational system. ''All students'' should have quality access  to science, technology, engineering, and mathematics (STEM) pre-college coursework in order to bridge the digital and equity divide.

To address this challenge, we developed a teacher professional development (PD) program and a toolkit consisting of a hardware and software system to engage STEM teachers in learning about wireless  technology  through  various  hands-on  activities  and  collaborative  research.  Through  the  PD  program and  the  development of the ‘COSMOS Education Toolkit’,  the COSMOS research testbed  is  transformed  into  an  innovative  learning  platform  for  K--12 urban students that would provide significant educational benefits for the  local  community.

The hardware setup of the 'COSMOS Education Toolkit' is inspired by the testbed's nodes. It consists of various off-the-shelf components, which, in  combination with dedicated software, allows the teachers to execute a vast number of real-world experiments. The  software  system  has  been  designed  around  a  web-based  graphical interface enhanced with an  easy to use philosophy on the execution and management of the  lab activities. The students access the graphical interface to navigate and select a lesson, execute the lab activity,  and  collect  the  measurements  with a similar philosophy as the COSMOS testbed.

== COSMOS SandBox1 ==
The SDR experiments of the 'COSMOS Education Toolkit' have been evaluated in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1 sandbox 1] using the outdoor sub-6 GHz deployment. In this tutorial we will use a large {{{s1.lg1}}} and a medium node {{{md1}}} of the 'Main Rooftop SDR Deployment'. Both of the nodes are equiped with a USRP Krypton 2974 via PCI-e.

=== Node Setup ===
Follow the steps below to gain access to the [wiki:Architecture/Domains/cosmos_sb1 sandbox 1 console] and set up nodes with appropriate images. 
 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account]
 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on sandbox 1
 1. [wiki:/GettingStarted#LogintoyourReservation Login] into sandbox 1 console (console.sb1.cosmos-lab.org) with one SSH session. 
 1. Make sure all the nodes and devices of this reservation are turned off:
{{{#!shell
omf tell -a offh -t system:topo:allres
}}}
 1. The image education-toolkit.ndz is [https://wiki.cosmos-lab.org/wiki/UserGuide/DiskImages#BaselineGnuRadio baseline_gr.ndz] with the COSMOS educational framework, and the K--12 educational labs and with their lesson plans. Load education-toolkit.ndz on sdr2-s1-lg1,sdr2-md1.
{{{#!shell
omf load -i education-toolkit.ndz -t sdr2-s1-lg1,sdr2-md1
}}}
 1. Turn all the required resources on and check the status
{{{#!shell
omf tell -a on -t sdr2-s1-lg1,sdr2-md1
}}}
 1. Check that the nodes are turned on
{{{#!shell
omf stat -t system:topo:allres
}}}
