Lecture Capture on the Cheap – Part 2.

Another successful lecture experience

This is the second part of my post on lecture capture.  You can find part 1 in the previous blog entry.

After a week in class, my lecture capture bugs have been worked out.  I wanted to give it some time because things rarely go smoothly and they didn’t here, either.  I discovered some elements were not in place and I’ll share what I’ve learned.

For me, the biggest factor was finding a good microphone.  Screen capture is not an issue, there is a killer app for that.  Camtasia Studio is a software package that has been around a few years – it does the screen capture well, and will sync a voice over that.  The software is sold by Techsmith and they are a company committed to selling products in the education space.  They have a collection of how-to helps and videos.  Even more impressive, if you shoot them an email, you get a personal response right back, often complete with personal praise for the way you are using their product.  Techsmith is a great resource and there is no software I know that competes with Camtasia.

Lecture Capture on the Cheap – Part 1.

Are we asleep yet?

I keep seeing those stats on the low viewer numbers for the lectures put online by UC – Berkeley and MIT, the stats that show us that people will prefer to spend buckets of money for tuition even when they can get the same for free by watching the lectures on Youtube or downloading to their iPhone.  Nobody is watching those videos.

That may be right about the general public but I’ll wager heavily the students in the classes are watching.

I started making problem solving videos for my chemistry classes 8 years ago.  I purchased the first version of the Sony Vaio because they (supposedly) offered breakthrough technology that made video creation a snap.

Ha!  Creation was cumbersome and slow but I found that when I got something up online, numbers greater than 85% accessed the videos for help.  My school (University of Idaho) has always offered great internet access – I know, Idaho? It’s in the sticks.  But check out the facts, Yahoo put us in the top five for educational access when they started measuring these things in the dark ages. Even though access was slow relative to today, students put in the time to download these videos and use them.  I learned their value as instructional tools back then and I am even more confident they are useful tools today.  Not so much as the primary means for providing content but as a super  source of notes, or to fill in blanks or to provide feedback after practicing alone.  That is the real proof – do students use a resource.  But I’ve also tracked performance in class and students achieve better scores when I can provide more resources.  For example, I’ve done experiments where I offer a homework assignment that serves as a pretest.  In one case I provide video that walks viewers through each problem step by step and in the other case, the students are left on their own.  I then give the two groups an exam over the same learning objectives and the video group has performed 22% better.  That’s significant.  I haven’t been able to tease out whether the important factor is the video or simply providing more resources but the simple answer is clear, the more resources, the better.  It might be that the students do the work with video and without, they rely on a friend to feed them answers.  I’m not sure of the reasons yet.

So this year I am committed to putting all of my lectures online, which takes us back to the beginning of this post.  I’ve wanted to do this for a long time and I am crazy jealous of the Berkeleys and MITs that can do it.  Faculty at each of those schools call the IT department on Tuesday and a camera crew shows up on Wednesday to record the whole thing.  That is the way it should happen – tuition is high at those places, they can do it.
