Standardized tests certainly aren’t going anywhere. States that have dumped exams aligned with the Common Core aren’t dumping high-stakes testing; they’re just switching to new tests, like the ACT’s Aspire. (Other ACT offerings include the Explore, the Engage and the Compass. Apparently standardized tests are titled by the same people who name midsize sedans.)

The Common Core is the way math was taught before. True, the new South Carolina standards are 92 percent aligned with the Common Core. But the Common Core was 97 percent aligned with the math standards South Carolina was using before! The term “number sentence,” which the comedian Stephen Colbert mocked, is 50 years old, and the kind of problem it describes appears in textbooks from the 1920s.

Teens and tweens, for instance, generally reported spending much more time watching television than they did on social media.

Black teenagers spent a daily average of eight hours and 26 minutes on screens for entertainment purposes, according to the report. That was two hours and eight minutes more than their white peers. Within that screen time, black teenagers spent most of their time — an average of about four hours daily — on smartphones, compared with about three hours for Hispanic teenagers and two hours for white teenagers.

If we have learned anything over the last decade, it is that advertising and data-collection models are incompatible with a trustworthy social media network. The conflicts are too formidable, the pressure to amass data and promise everything to advertisers is too strong for even the well-intentioned to resist.

the real challenge is gaining a critical mass of users. Facebook, with its 2.2 billion users, will not disappear, and it has a track record of buying or diminishing its rivals (see Instagram and Foursquare). But as Lyft is proving by stealing market share from Uber, and as Snapchat proved by taking taking younger audiences from Facebook, “network effects” are not destiny. Now is the time for a new generation of Facebook competitors that challenge the mother ship.

When a company fails, as Facebook has, it is natural for the government to demand that it fix itself or face regulation. But competition can also create pressure to do better. If today’s privacy scandals lead us merely to install Facebook as a regulated monopolist, insulated from competition, we will have failed completely. The world does not need an established church of social media.

What I was doing was perfectly legal. In North Carolina, long-gun transfers by private sellers require no background checks.

hat the education system must adjust to better accommodate the way students learn, a point that some teachers brought up in focus groups themselves

roughly 75 percent of 2,462 teachers surveyed said that the Internet and search engines had a “mostly positive” impact on student research skills. And they said such tools had made students more self-sufficient researchers.

But nearly 90 percent said that digital technologies were creating “an easily distracted generation with short attention spans.”
