Creating Tutorial Videos with Explain Everything

I've used a number of different math tutorial videos with my students over the years - mainly from Khan Academy, but from a few other sources as well, but though I've been meaning to create some of my own, I just hadn't got around to it until recently. Several factors inspired the set of videos I just created. First, while teaching graphing Spring term, there were some consistent issues that I thought videos could help address if students could access them while working on homework outside of class. Second, I've been interested in iPad screencasting and wanted to try out the Explain Everything app. Finally, while I find videos made by others to be helpful, I think that my students would really benefit most from being able to watch / listen to me explain concepts the same way I explained them in class. With those things in mind, I set to creating a series of videos on graphing equations in slope-intercept form.

Explain Everything is available through the Apple App Store for $2.99. There are some things that I really like about this app. The interface is generally pretty intuitive, though there were a couple of menu buttons that I had to play with a bit before really figuring out what they could do. You can create files with multiple pages so that when you do your screencast, you can record each page separately (and go back to edit single pages) but create one seamless video in a single step. Photos and videos can be imported onto slides; you can add text and drawings to slides; and you can minimize/expand and move around elements on a slide. In addition, you can open a video recording screen on a slide and record video right into the app. Finally, you can open a live web page on a slide. Recording quality is good and I found the audio to be satisfactory, even when using only the iPad's built in microphone. Uploading to YouTube was a little slow but not at all difficult.

There are a few things that I don't like about the app. Editing videos seemed a little glitchy - when I would pause and try to re-record a section of video, the active tools would switch on me, and a couple of times changes that I made to elements on the screen didn't "stick" as I started recording again. I believe that you're supposed to be able to edit video and audio separately, but I had a little trouble with this. When you open a live web page, the page loads quickly and page elements are functional, but web page text and graphics (and especially video) are lower resolution than in a browser. Finally, while there is a tool for inserting elements like arrows and lines on slides, it's really limited in the shapes it can create; I'd like a more robust shape tool.

I plan to play around with this app a bit more, but based on my initial impressions, I would recommend this app to anyone who really wanted to screencast from an iPad, with the caveat that this is not the best screencasting tool out there. For my next video project, I intend to use a web based tool (like Screencastomatic) on my PC. 

As for the videos themselves, I don't think they're too bad for a first try. I did realize after completing my fourth video that I did not use a single example with a negative y-intercept, so I might go back and either change one of the videos or add another to the set. I had been told by a number of people to write a script before recording, and that was good advice. I did find that I needed to revise and adjust my scripts as I went along, but they were good guidelines. The biggest challenge I had was making sure that there was nearly always something going on onscreen - I tried to avoid having too many segments with more voiceover than visual. 

Thinking ahead to making future videos, I'm toying with the idea of recording myself at a whiteboard or chalkboard, rather than screencasting. I did start each video with a little clip of myself - another great piece of advice I'd been given was that students like to see a picture of the person behind the voice on the video. I think for a lot of students there is something to watching a teacher explain something - the gestures, body language, and other visual cues add something important to the instruction, and I always feel like that's missing from screencasts. So stay tuned for future videos - maybe you'll see more of me in front of the camera!

SoftChalk

I've been meaning to learn about SoftChalk this year, but the workshops offered this past term or two didn't sync very well with my schedule. So I was grateful when Alice Warner set up a SoftChalk workshop during finals week - thank you, Alice!

Meredith Keene-Wilson did a great job of introducing SoftChalk and helping us put together a couple of activities that we'd be likely to use on our Moodle sites. I appreciate SoftChalk for its simple interface - I like programs that keep the screen pretty clean so that you can focus on what you're building.

I think that I'll be using SoftChalk quite a bit in the future to create online content for my students. In addition to teaching content, a big focus of my classes is getting students accustomed to working online so that they'll be comfortable with online testing, as all of my students are preparing for either the Accuplacer, math placement exam, or GED - all of which are now or will soon be computer-based. Though there are some good resources out there for computer-based practice in these areas, I often need or want to create my own materials, and Moodle's tools for this are pretty limited. Especially for the new GED format, it will be valuable to be able to replicate some of the question types.

As far as specific content goes, I've already thought of several ways I could use Softchalk. In my reading class, I've been focusing on vocabulary development, and there are several activities (matching quizzes, multiple choice exercises, the crossword puzzle maker) that could support this. The identify activity could be used to help students use a visual modality to study terms and definitions or connotations.

I really like the HotSpot activity and have several ideas for using it. For writing, students could be given an image of a sentence and asked to identify parts of speech. In reading, students could be given an image of a paragraph and asked to click on the topic sentence. In geometry, students could be given a diagram and asked to click on various parts of a figure. In algebra, an image of an equation could be used to test student knowledge of correct terminology for different parts of the equation (variable, exponent, coefficient, etc.).

Another feature that I really like is the TextPopper. My students often have widely varying backgrounds, and I like the idea of being able to add supplementary information to text lessons without having to actually include that information as part of the content. This could also really help out ELL students, as you could use TextPoppers to define difficult words or idioms.

I'm looking forward to using this tool to enhance my Moodle sites and encourage online student learning.

Digital Badges

As a young Girl Scout, I was a fervent badge-earner, so when I saw the listing for the Badges in Education workshop during Spring Inservice, I knew where I'd be spending an hour. For those of you who didn't attend the workshop or don't know about digital badges, today's badges don't get sewn on a sash - they are digital icons that students can earn in recognition of various achievements.

Digital badges are an example of the gamification of education: the application of gaming principles to educational settings. If you've ever played a video game in which you were rewarded with a new life, a special power or tool, or some other kind of recognition or bonus for earning a certain level of points or reaching some other achievement, you'll understand how digital badges work. Just as many of us will repeat levels of Angry Birds in order to achieve the full three stars on each level, students are motivated to complete lessons or quizzes in order to earn digital badges that they can post and share on course management or social media sites. (For more on gamification, see Gabe Zichermann's TED Talk ).

 So how are digital badges any different than sticking a gold star or stamping a smiley face on a student's paper (also surprisingly good motivators, I've found)? Well, because they are digital, they can be more widely shared. Sure, a paper with a sticker or stamp can be shown to friends and parents, or hung up on the fridge, but that's about as far as most students would choose to share them. Digital badges, however, are portable - they can be shared on special badge sites, such as Mozilla Backpack, on social media sites like Facebook or Twitter, or on a personal web page or blog. As a result, students can show off their badges to a larger audience for an indefinite period of time.

Perhaps the key difference between a sticker and a digital badge is that the badge is embedded with metadata that authenticates the issuer, the requirements for earning the badge, and other information. This gives the badge a legitimacy and use beyond the original issuer and recipient. A student could use badges as evidence of accomplishments in a portfolio or resume, for example. In my department, where we do not issue grades or credit, badges could serve as evidence of successful completion of units, classes, or skill levels.

Mozilla has a good FAQ with more information on digital badges here.

Following the workshop, I created a Mozilla Backpack account and completed my first badge - the Web Navigator badge, which required that I practice some simple web navigation tools. I then opened an account with Credly, a site where you can build and issue your own badges. Credly has some nice customizable badge templates, or you can start from scratch with your design. I chose to start with a template, and it took me about ten minutes to design a badge that I plan to use for completers of my Math 4 class. The design process was very straight-forward; the hardest part was deciding what information to include in the badge description. This

probably would have been easier had I looked at the information attached to other badges before I started mine, but I just jumped in with both feet. Fortunately, it's pretty easy to edit badge information.

Students don't have to be members for you to issue them credit - if they are, you can easily use their member names to send them credit, but you can also send them a badge via email. You can also upload a csv file to send a badge to a whole group. When you issue credit, there is also an option to add a testimonial about the student's achievements and a link to add evidence from a web page that supports the student's accomplishment.

I plan to use badges in my courses next term. To begin with, I plan to offer badges for completion of units and the course - and I imagine I'll structure the badges so that students must earn the full set of unit badges in order to earn the course completion badge. In the future, I can see breaking this down even further - giving concept badges or project badges, which lead to unit badges, which lead to course badges - but for now I plan to start with a simple structure. I understand that the newest version of Moodle will incorporate badge display, which will make it even easier to issue and use badges in our classes.
