Teaching with Online Videos

Thanks to YouTube et al, creating a lesson around a video is one of the easiest and popular ways to teach kids esl. But getting the videos from the Internet into a more presentable form, like a Power Point file, requires a little bit of extra work, especially when your class room is state of the art, circa 1980. In some previous lessons I've used downloaded videos and figured out a process of getting videos from my home Internets into my classroom presentations.

Downloading Videos

If your school trusts you with a live Internet connection that directly spews into your classroom, you're in luck. Others end up with either no Internet or a crippling firewall that does not allow any fun at all. Downloading the videos to a CD (or whatever) at home and bringing it into the school side steps this problem completely.

Finding the video is straight forward but while some sites let you download the video directly, others aren't as generous. So far the easiest and most fail-safe way that I've found to download videos from the Internet is through DownloadHelper, an extension to FireFox. I'm already using FireFox and its other extensions so I'm partial to DownloadHelper in a keep it in the family kind of way, but there are some valid alternatives, like the web-based VideoDownloader site. But so far DownloadHelper has proven the most reliable thanks to the massive list of video sites that it has been tested against.

Playing Videos

Most of the videos on the net are in the flash video format (*.flv files) and there are tons of options for playing these files and you'll have to convince your school that it's okay to install at least one of them. I convinced my school to install K-lite by simply installing myself and not telling anybody about it. So far nobody has complained.

Now, K-lite is a Swiss army knife of video manipulation and is really intended for people who know about encoding and codecs and other computer geekness but it's super easy to install and use. There are multiple versions of K-Lite and the standard is a good entry point since it'll install the the FLV codec as well as Media Player Classic, a simple movie player that is free the bells and whistles featured in other applications.

Embedding Videos into Power Point Slides

Embedding flash videos in Power Point files creates a nice smooth transition from slide to video and back to slide. Embedding videos into Power Point slides is fairly common problem and easily solved by other people. Unfortunately most versions of Power Point do not support the *.flv file; they do, however, support embedding Windows media video format (*.wmv files). And quite fortunately, you can convert between one and the other thanks to the good people at media-convert.com.

Videos in Power Point are not really embedded, but linked. This means that if you want to share your presentation you'll need to be sure that you also share the video files and that they are placed in the same folder as the Power Point file.

Alternatives
There are some alternative methods to using videos but so far my favourite ones are the video tutorials done by reponzo01:

Microsoft Office Viewers and Converters

Microsoft Office has a considerable market share in North America. Same here in South Korea. So chances are that you won't have to rely on another office suite to do your lesson planning.

Unfortunately this doesn't mean that the version of Office you have on your laptop is going to be the same version that you have at your school. Usually this doesn't matter, but for the heavy PowerPoint 2007 user (like me) who creates on an English machine and presents on a Korean machine, converting is an essential way of life.

Microsoft maintains a collection of converters. The same page also has a collection of viewers which are great in the rare case that you get a computer without Office installed. And the new version of Office has a completely different file format (*.docx, *.xlsx, *.pptx, etc) that is still not as readily accepted as the previous file formats (*.doc, *.xls, *.ppt, etc). For these files, Microsoft provides a converter by way of the Compatibility Pack.

And of course if you don't want to download any software, there's always the converters at Zamzar.

*.hwp files

These files are document files created by the Korean equivalent to Microsoft Word, Hangul Word Processor by Haansoft. For non-Koreans, there's a bunch of information already on the web, including this English translation of the corporate and product page, some information about the history of Hangul and entry on Wikipedia that mentions:

To open HWP files in a non-Korean Windows system, users can download and execute a conversion program [1], which enables files to be opened with Microsoft Word. This program, however, can only be used with files created with Microsoft Word 2000 and below. Haansoft has also a Hangul document viewer program freely available on its website called "Hangul Viewer 2005" (한/글 뷰어 2005) [2].
The information on the wiki is a bit outdated since navigating the Haansoft website reveals a 2007 viewer and another search reveals updated information regarding Microsoft Office 2007. And if you're dealing with this file, then you are probably doing so because of school; most schools have a site license for Hangul so installing the application could be as easy as a short call to the school's IT department.
