An emphatic “YES!” to everything in here. These are the first two:

1. Good video doesn’t always mean good audio. While it’s easy for a student to see what their mobile camera “sees,” it’s impossible to hear what their mobile microphone is hearing without wearing headphones connected to their device. In our first in-class interview practice, students almost always hold their devices too far from the interviewee. Yes, it can be awkward holding a phone near someone’s face, but unless you have a handheld microphone that plugs into the phone, the device should always be within arms length of the interviewee’s mouth for good audio. The common “camera position” of holding the phone near your face doesn’t work for video interviews. it’s always more important that the device be closer to the interviewee than it’s to the interviewer. TheMobileActive web site offers more tips for good mobile audio.
2. Brevity is the soul of wit. Tell students to keep their interview questions focused and video clips as short as possible. With some practice, it’s relatively easy to stop and start the recording instead of capturing an entire 15 to 20 minute interview. (That also results in a huge video file.) With the right mobile app, each clip can be automatically uploaded to the cloud while the interviewee starts the next question and recording. In general, students should have only three or four good questions to ask.  If the interviewee rambles for several minutes, stop then start recording again asking the interviewee to summarize in a minute or less what they just said. This also produces a more focused and shorter clip for online viewers to watch later.

Lots of great advice here.

We need some alternatives to Khan Academy for many reasons. Here are some free tutorials for teachers and students on just about every kind of math imaginable.

This research shows that the value in Khan may actually be the problem sets and gaming like awards system that accompanies it.

“Like many, we assumed the videos would be the predominant learning mechanism for students tackling new material. In fact, the students rarely watched the videos. This result is consistent with some of the observations in the Los Altos pilot. The students greatly preferred working through the problem sets to watching the videos. “
