Here is the system as delivered to the Children’s Home. One Rachel-PI, 12 Lenovo 10" tablets, 12 wired keyboards (I originally was looking at using Bluetooth and then realized what a debacle that would be) and 12 sets of headphones. The tablets themselves are Lenovo Tab 10 devices (model number TB-X103F) which were purchased retail for about $105 each.
The tablets were loaded with Word, Excel and a simple bible application. Unneeded or confusing apps were either uninstalled or disabled; such applications as YouTube, Gmail, Downloads, Drive etc. Anything that was deemed to be a distraction to the kids was hidden.
The priority users for the system are the junior high age kids while the younger ones have access also. It is interesting that the younger ones are the most enthusiastic about being able to use the system. 8 or so are deployed while the remaining hardware is held in reserve as replacements.
So far the reception by the adults and the tutor at the home has been wonderful. It is understood that this is multi year project and the results will be measured in test scores for high school placement.
At this time the system has only been in place for a month or so and there is not been time to create material specific to Ghana.
