Khan Academy and Google Sites Changes

Just finished KA Grade 7 Math as a fictitious student, so I needed to set up another chart and table section to the KA2 page.  Should have been easy to add another chart from the same tab in Excel, but Onedrive wouldn’t recognize it, even though it was clearly there in Excel.

Finally had to make another worksheet and add the new table and chart for Grade 8 Math to it.  That satisfied Onedrive and I’m back in business.

The other change I’m messing with is to copy and paste the entire list of individual student skills mastery from Khan Academy into a new tab in the workbook.  Looks like this will save considerable time versus c&p each section.

I put in a request for new features to the KA support forum, but don’t know how much that is monitored.  What I need to be able to do is download data from all students and all skills at one time.  If I had a full classroom of students, doing it like I am now would be extremely tedious.

Automation, right?

Time to Upgrade the Computer Lab


This is the first year I’ve had kindergarten students coming to the computer lab who are touching the monitor, trying to follow my directions.  We don’t have touch-screen monitors in the lab, so I’m assuming that they are bringing this behavior from their experience with the technology they have at home.

Modifications I’d like to see to the concepts shown above:

  • Computer lab tables would have a hollow, single center-pedestal leg to house electrical/network wiring and allow free movement around the table without tripping on wires and corner legs.
  • Screen surface skin customizable to create different tactile conditions, such as paper, so user can experience the friction of a pen or pencil on the surface when using a stylus.
  • Screen surface skin able to produce an elevated keyboard with clear differentiation between the keys, and keyboards of different sizes to match the size of the user’s hands. This last feature would be especially appreciated by my kindergarten students.
  • Screen can be split into sections, and the sections can be rotated.
  • Configurable key labels, whether upper/lowercase, or language.  My kindergarten students are initially confused by seeing all uppercase letters, then lowercase letters on the login screen as they enter their username.
  • Connection between adjacent desktops, so a document on one can be cloned and swooshed over to the next, with the option of sharing the file with anybody/everybody in the lab
  • Instructor’s workstation would be able to see the entire lab at once as well as zooming into any combination of the individual desktops.
  • Instructor’s workstation can display on all workstations at once
  • Workstations can run multiple operating systems simultaneously.
