Prezi in Education

New technologies are always developing that can be useful in the classroom. Over the past couple of years, Prezi started as a small start-up with a unique idea and has developed into a very usable alternative to PowerPoint and Keynote for creating presentations.

Prezi is very different in that, rather than a collection of slides presented in linear fashion, the presenter prepares a canvas that contains all of the material – text, images, even online content – that can be browsed, zoomed, spun, and more. You may be familiar with the idea of mindmapping – starting with a core concept and connecting related ideas in a web-like diagram. Prezi builds on this idea and adds an interactive level.

Where Prezi really shines in the classroom is the ability to show the big picture as well as the finer details.

Recently, the team at Prezi launched a resource called Prezi Explore, a collection of presentations licensed for reuse and adaptation. This is an excellent resource for teachers who can grab a prebuilt presentation on a difficult concept and use it to give a new perspective to their students.

One of the Prezi presentations included in this section explains how Prezi can be used as a teaching tool. Browse through it and see some really great examples of how the tool can be used in the classroom to help students have a better understanding of the topic.

Companion Term for Slideument

Last week I shared my thoughts on Kashi's confusing use of slides to present what was essentially a document. In retrospect, I might have been a bit incorrect using the term 'slideument' which more accurately applies to a set of slides that read like a document.

Two great examples of slideuments are 8 Keys to Effective Lecture by Terry Doyle at Ferris State University, or How Do I Use PowerPoint to Teach by Patrick Crispen (links are direct downloads to the PowerPoint files).

While the content in both of these presentations is valuable, presenting it in slide form does not make sense, since they were dense with text, did not use many visuals, and flowed much more like an essay.

On the other hand, Kashi's Yearbook celebrating 25 years was designed as a document but presented as slides... docuslides?? With this practice becoming common with online services such as SlideRocket and Slideshare, maybe it's time to coin a new term to use in conjunction with slideument.

Docuslides. I like it.

Why a neuroscientist doesn’t use PowerPoint

During my semester studying anatomy for my undergraduate degree, I began downloading podcasts via iTunes U to supplement my own lecture experiences. I came across an anatomy course taught at UC Berkeley by the wonderful Prof. Marian Diamond. While listening to the first lecture in the series, I was extremely impressed with her calm and authoritative demeanor. All at once she exudes confidence and respect toward her students. After a short pause during the lecture to erase the chalkboard, she said, "I have to tell you why I don't use PowerPoint." I was overcome with excitement and anticipation as I waited to hear why this capable teacher purposefully abstained from using a popular technological tool. What followed was a brief yet powerful statement that every teacher who uses lecture slides should consider. I include it here verbatim:

"I have to tell you why I still use chalkboard and do not use PowerPoint. Because I've studied learning mechanisms long enough to know that it takes time to take in the primary information and associate it. I feel if I just flash on things like this you don't get it. If you write, you use your kinesthetic sense. That's one way. It slows me down, it slows you down. And I also repeat all the time, because we know repeating reinforces. First time through you have an ionic exchange, second time through you have protein synthesis. So we're using things that have been shown for learning rather than just keeping up with the technology."

Here is an audio clip so you can hear it yourself. Or you can download the full lecture audio from iTunes U.

I was thrilled with her explanation! It wasn't because she couldn't use PowerPoint, found it too cumbersome, or time consuming. It was simply that there was no pedagogical reason to use it. As far as learning is concerned, using the chalk board and encouraging the students to take notes is far more effective than flashing something up on the screen.

After further investigation, it seems as though Professor Diamond makes a similar statement at the beginning of every semester (see Fall 2007 and Fall 2008). This suggests that it wasn't just a passing thought in casual conversation, but that it is important enough for her students to understand the deliberate choice she made to improve their education.

Now, I am not saying definitively that you shouldn't use PowerPoint. But if you do, there had better be a darn good reason. Don't use it just because it's easier or because you want to look cool using 'up to date technology.' And further more, if you do use PowerPoint, you'd better make them darn good slides. That's what this blog is all about, so be sure to read some other posts. You might like to start with 2 Design Changes That Follow All Brain Rules, since we are talking about neuroscience here.

(Professor Marian Diamond is a professor in the Department of Integrative Biology at U.C. Berkeley. Her research includes neuroanatomy, environment, immune functions, and hormones. She has taught all over the world.)

In a previous post, I introduced 2 Design Changes that Follow All Brain Rules.

2. Use More Images

For thousands of years the human brain has developed to process the visual input received through the eyes from the surroundings. Survival depended on being able to see the mammoth from far off, spot the snake in the grass, or the color of fruit in a tree. Only recently in its evolution has the brain's visual system spent so much time decoding letters, such as the ones that make up War & Peace. The cortex of the human brain has developed immensely to be able to read and ponder such literary works, not to mention complex scientific textbooks. And yet, even now, the brain still responds more actively to vibrant pictures.

Trade weapons for art. Replace your bullet points with high quality photographs. Bullet points are great for shopping lists and talking points, but not for getting your point across. They just don't work, because text is boring and lists are distracting.

If each item truly is that important, create a separate slide with a high quality image that represents the idea. Or use an image to represent the overall idea of the list, and verbally give the key points of the idea.

Go ahead and bleed. Using a full screen image is much more effective than copying the thumbnail from a Google search. Instead, download the full resolution file and fill the screen with it.

Don't clip to save. This is one instance when cheaper isn't better. Don't use the built in clip-art for graphics. Dip into your classroom funds and purchase stock images for the really important lectures. Web sites like iStockPhoto sell high quality images for relatively low prices. Once you sign up as a member, you can access their Free Image of the Week. Collect these over the years and you'll have a substantial library of great images that are bound to fit in to your lecture slides somewhere.

Join the commonwealth. Ok, so most classroom budgets won't get you very far, but there are alternatives. You can access a wealth of images created by amateur and professional photographers who license their images for reuse – it's called a Creative Commons license. I explained how to do this in a previous post.

But that's not all! There are many organizations who provide many of their images for free. Just for starters, visit some of these sites:

DIY. If you're still struggling to find the image that you want, get creative and Do It Yourself. Grab a digital camera (a 3-megapixel camera is commonplace today and is sufficient quality for a presentation) and make the image yourself. Take a moment to review some basic photography concepts, such as the Rule of Thirds and lighting, at a website like Digital Photography School and then go out and explore your inner Ansel Adams.

There is so much more that we could discuss in relation to the use of images in your lecture slides, but they can be addressed in future posts. For now, see how you can improve one of your lecture slide decks by using less text and more images.
