Uneditted Videos

I have been struggling for some time now about creating and posting videos for my students and classes, because I am a perfectionist.  If I'm going to post something, I want it to be done well. When creating a video, I have yet to record myself perfectly. I constantly will make mistakes, say things twice, repeat myself, or say things twice constantly. Even if I don't make a mistake, my speech is so littered with "um" and "so" that it's embarrassing counting how many times I eliminate those.

Typically, when I create a video, it takes me 3-4 times the length of the video to edit it and do what I would consider a "great" job. For day-to-day lessons, that has proven to be unfeasible.

On the trip home today I listened to live radio and was reminded that the real world has a lot of mistakes, but that doesn't stop them.  So I decided that I would start publishing more videos -- but in a raw, uneditted format.  I will still produce high quality videos, especially for my physics class which is "flipped" and depends highly on video lectures for input, but I don't feel I need to do as high quality a job with my algebra videos, which aren't as highly viewed.

The same thinking, by the way, is the reason I don't blog very often -- maybe once a week.  I feel like I need my entries to be deep, rich, well written entries -- but they really don't.  After my Master's project is finished, I'll try to express more thoughts in rougher un-editted form.  Be ye warned....

Some Systems Videos

Hey guys,

It's been a while since I've posted anything since I've been working especially hard creating a lot of videos for my classes at school.  I'm now back into a flipped unit in physics, studying Torque and rotation with my students. If you're curious, you can follow the unit at our class website. I am creating this unit as a sample of a flipped unit for my Masters project at Cornerstone University, so I'm taking more time perfecting it than I normally might -- thinking about tying all the things I've learned together.

I've also recently created several videos for my algebra 1 students.  Though I am not flipping that class -- I do have a lot of students who are absent a lot, and I thought it might be worth it for those students for me to post videos of the lectures online.  Since I already have all my equipment up and out and ready for my physics classes, I talked through my algebra lessons too and here are those videos:

This is an introduction to systems of equations, and my explanation of the graphing method of solving systems:

Here's the substitution method, which we'll be studying next week -- I like the colors in this video -- it turned out pretty:

And here's the elimination method, or what my text book calls "linear combinations".  Elimination is a much sweeter name.

This is probably one of my favorite lessons to teach -- I just think the combining equations and one variable disappearing is a beautiful magic trick -- makes me feel like a mathmagician, as some of my students say.  The only thing cooler than adding two equations together and having variables cancel out, is dividing two equations together and having variables cancel out, a trick I often do in physics, especially when sine and cosine values are around.

Interactive Tabs in Powerpoint

Here's my first official attempt at making a video with Camtasia. This isn't technically for a flipped lesson, but I wanted to try to increase my skills a little on something that wasn't for my students, before diving into that.

This video shows how to add a cool interactive tab onto a powerpoint slide so you can hide information that you might not need, but can reference if necessary.  I stole this idea from the SMART Notebook software I used for a week this May when I had access to a smart board, and thought of how I could implement it into powerpoint.  Hope you enjoy!

First Vodcast - Using Camtasia

This is my first go around at making a video using Camtasia.  It sucks.  The video that is, the program is actually pretty cool.  I would have had a video yesterday, but my computer does not have a good microphone, and the microphone jack on this computer doesn't work either.  I had to borrow my friends usb microphone headset, which works great I think.

The program automatically converted my voice into close captions, see if you can turn them on.  The close captions are not even close to what I said, I think it might have 30% of the words right?  But supposedly I can train them and they will get better.
