The People vs. Columbus, et al. » Zinn Education Project This role play begins with the premise that a monstrous crime was committed in the years after 1492, when perhaps as many as three million or more Taínos on the island of Hispaniola lost their lives. (Most scholars estimate the number of people on Hispaniola in 1492 at between one and three million; some estimates are lower and some much higher. By 1550, very few Taínos remained alive.) Who—and/or what—was responsible for this slaughter? Associative model of data The associative model of data is an alternative data model for database systems. Other data models, such as the relational model and the object data model, are record-based. These models involve encompassing attributes about a thing, such as a car, in a record structure. Such attributes might be registration, colour, make, model, etc. In the associative model, everything which has “discrete independent existence” is modeled as an entity, and relationships between them are modeled as associations.

Google Documents and Common Core Standards As I mentioned in my previous post, today I spent the day working with teachers on using Google apps to address some Common Core standards. One of the things that I love about working with other teachers is the opportunity to learn from other teachers.

Some technology schools should stop buying TODAY For about as long as I can remember I have carried a Swiss Army knife in my pocket with my change. It has a small blade less than an inch and a half long, a screwdriver blade/file, a small pair of scissors, a toothpick, and tweezers. My understanding is that actual members of the Swiss Army can use such a knife to kill an enemy in a dozen different ways, but I use mine primarily for opening boxes, trimming my finger nails, and cutting tags off things.
