Instagram positioned itself as the third most popular social media app
and the best social media app of 2016.
Twitter saw a decrease in users over the past year and even death of their beloved 6-second video-clip sharing app, Vine.
In an article entitled ‘Why Vine Died,’ Casey Newman reported the following, “Former executives say that a major competitive challenged emerged in the form of Instagram, which introduced 15-second video clips in June 2013.
Instagram remained stable with the introduction of new features like stories and video channels, resources of it’s parent company, Facebook, and the introduction of ads to the platform that look very similar to the posts in a user’s feed.
In addition to a total logo redesign, Instagram shifted its focus from just pictures, to longer video (from 15 sec. to one minute) and direct messaging features, such as group posts and disappearing video. Explore Channels in Discover let people discover new photo and video content based on interests. Instagram Stories added a new element to the Instagram experience showing highlights from friends, celebrities and businesses one follows without interfering with their feed. Instagram also caters to business needs through its Instagram for Business platform that allows for instant contact, detailed analytics and easy-to-follow linked content.
Most recently, Instagram released live video in their stories feature. Users can start a live stream in their Instagram story and view comments and feedback from their viewers in real time! This feature is similar to apps like musical.ly and live.ly which has over 80 million users and 62% of its users are under 21.

Why Girls Tend to Get Better Grades Than Boys Do
New research shows that girls are ahead in every subject, including math and science. Do today’s grading methods skew in their favor?
The latest data from the Pew Research Center uses U.S. Census Bureau data to show that in 2012, 71 percent of female high school graduates went on to college, compared to 61 percent of their male counterparts. In 1994 the figures were 63 and 61 percent, respectively.
Girls succeed over boys in school because they are more apt to plan ahead, set academic goals, and put effort into achieving those goals.
The weaker sex
For all the data and feedback they provide, student information systems interfere with learning.
“School isn’t about learning. It’s about doing well.”
The singular focus on grades that these systems encourage turns learning into a competitive, zero-sum game for students.
the parallel with the online grades systems at K12 is the Big Data movement at Higher Ed. Big Data must be about assisting teaching, not about determining teaching and instructors must be very well aware and very carefully navigating in this nebulous areas of assisting versus determining.
This article about quantifying management of teaching and learning in K12 reminds me the big hopes put on technocrats governing counties and economies in the 70s of the last centuries when the advent of the computers was celebrated as the solution of all our problems. Haven’t we, as civilization learned anything from that lesson?
