Teaching poor children effectively is difficult. But at least one effective model seems to exist. It requires human capital resources that most schools don’t have and it’s not entirely clear how much of those resources can be obtained. But it’s genuinely not clear[…]
How big can this [KIPP model] go at the end of the day? I have no idea. But there’s no reason to respond to this track record with pre-emptive pessimism.” —
The immediate reaction to promising models for education reform that require extraordinary commitments from teachers, parents, and students (like KIPP) is “Yeah, but can it scale? Probably not.”
Yglesias makes a crucial point here: who knows? And with evidence that KIPP really is improving outcomes for students, why not give it a shot?
Google breaks down mobile users into three behavior groups:
A. “Repetitive now”
B. “Bored now”
C. “Urgent now”
The “bored now” are users who have time on their hands. People on trains or waiting in airports or sitting in cafes. Mobile users in this behavior group look a lot more like casual Web surfers, but mobile phones don’t offer the robust user input of a desktop, so the applications have to be tailored.
The “urgent now” is a request to find something specific fast, like the location of a bakery or directions to the airport. Since a lot of these questions are location-aware, Google tries to build location into the mobile versions of these queries.” —
