I just got back from a trip to Peru where I met with the head of technology for the Ministry of Ed.

The biggest problem with the OLPC project was the fly-by dropping of the computers without appropriate professional development for the teachers. The OLPCs were simply delivered without regard for the training needs of the teachers in either content or pedagogy. Computer-based teaching requires different instructional approaches.

My recommendation would be to not just focus on the senses of sight and hearing but also on taste, smell, and touch. If she cooks or bakes, make sure you get the recipes for the things she makes that you like best, so you can experience them down the road. Keep her perfume or detergent or shampoo around, so you can smell them after she's gone. Keep her favorite songs handy to listen to. If there are specific artifacts that remind you of her, place them prominently in your home, or give them to your daughters to hang onto. Engage all of your senses for a more complete memory.
