As the novelty of PowerPoint presentations in the K-12 classroom fades, the dim lights and streams of text could inspire sleep instead of excitement in science. There are ways that science can be made interesting through PowerPoints. Interactions, great pictures and graphics can really help make a point and share a story.

Fortunately many teachers and people who support education are willing to share their efforts. Here are several powerful sites for science PowerPoint presentations. Of course, with any collections of resources, not all are great so you must browse through and pick and modify. I think combinations of interactive and exciting elements from diverse PowerPoints can make you have a presentation with many strong elements but that is tailored for your students and curriculum.

Back on September 11, 2008, I wrote about the new Spore game and expressed concerns about the way evolution is depicted. I also restated other reviewers’ comments that it is a boring game.  After the incredible hype approaching the release, the media has been pretty silent.

PBS’ “Online NewsHour”, however, did post this article in October: “New ‘Fun Biology’ Video Game Lets Players Tinker with Evolution”. It seems like PBS put “fun” in quotes because they know it isn’t really fun. The author, Quinn Bowman, goes on to reference my blog entry:

Educational value

Educators are mixed over whether Spore belongs in the classroom.

Professor Peter Rillero of Arizona State University wrote on his blog, which focuses on using technology to teach science, that the mechanics of the creature creation in Spore did not accurately reflect how evolution works.



“The notion of evolution as making choices, as deciding to come out of the water to be a land creature and therefore deciding what appendages to gain, and the thought that the more DNA you eat the more evolved are so wrong that I wonder why Will Wright considers this to be science inspired?” Rillero wrote.

”

But then Bowman adds this quote:

“However, University of Florida associate professor of geology Joe Meert said games like Spore ‘are a natural place for students to gravitate to.’ 

’Even the things that (Spore) gets wrong, it could be a teachable moment. Here’s something the game gets wrong.  Why is it wrong?’

Dr. Meert seems like a fascinating and good guy and he is someone who wants the public to understand evolution. So with some reluctance I say his comments remind me of College of Education field offices telling interns with crummy mentor teachers, “Well at least you will learn what not to do.” Spore tried to show itself as a great science education tool. We have to recognize first and foremost, that it is not. Teachers should have great mentors, our children should have great science education resources. 

I don’t go around boring my friends and family talking about scientific inaccuracies in the media around me.  I would not expect history educators to criticize Call of Duty’s portrayal of WWII history. Unless of course, the game made claims that it was a great way to learn history, and started touting all of the historians that had been consulted in developing the game. Spore, on the other hand, deserves to be criticized.

Not only was Spore incredibly hyped, it wanted to develop the idea that it would promote an understanding of evolution. This was evident in the September 9th TV Show: “Build a Better Being” produced and aired by the National Geographic Channel through a partnership with Spore. Getting famous evolutionary biologists to talk about their work, and then showing scenes from Spore, could have encouraged many to falsely believe that the evolutionary biologists were supporting it.

This is far from the case, and the journal Science reported complaints by scientists involved in the documentary. “I literally never heard about Spore until I saw myself on television in this infomercial about the game,” says Cliff Tabin, a geneticist at Harvard University. “It’s an outrage (as quoted by Bohannon, 2008).”

Other Voices of Concern

Fortunately, I am not the lone voice in criticizing Spore. Here are some other views that are critical of the “evolutionary science” in Spore.

T. Ryan Gregory and Niles Eldredge describe Spore in this way:

It is, in reality, a relatively standard real-time strategy game with the same basic unlocking of features, upgrading of levels, and choices about aesthetics and function as with vehicles or buildings in other similar games. The units happen to look like organisms, the features that can be added are mouths, eyes, and limbs, and the currency is called “DNA”, but really that does not make the game anything more than superficially biological.

John Bohannon wrote in “Flunking Spore”:

So over the past month, I’ve been playing Spore with a team of scientists, grading the game on each of its scientific themes. When it comes to biology, and particularly evolution, Spore failed miserably. According to the scientists, the problem isn’t just that Spore dumbs down the science or gets a few things wrong–it’s meant to be a game, after all–but rather, it gets most of biology badly, needlessly, and often bizarrely wrong.

Manure

How does the game’s creator Will Wright respond to the controversy? Well despite the scientific inaccuracies in Spore, he concludes:  It’s manure to seed future scientists” (as quoted by Highfield, 2008). Some quotes are so good they don’t need further commentary.

Enjoyment

Of course there is also the issue of how enjoyable this game is. Here is a clip from the New York Times (Schiesel, December 2008):

BEST DISAPPOINTMENT: SPORE If Electronic Arts has learned anything from its experience with Spore, it ought to be that a software company should just let its games do the talking, rather than relentlessly hyping a game for years before its release only to deliver a one-note electronic toy in the end. Spore would not have fizzled so quickly if expectations had not been so ludicrously inflated to begin with. Perhaps more important, it showed that maybe even a game god like Will Wright, the game’s creator, can stand to be reminded of the basics once in a while. Spore was great at letting the player create something from nothing. But in the end it just wasn’t that interesting to play with. Making cool stuff is a great part of video games, but the play, more than in any other media, really is the thing.

Promoting Spore

Yet, many people are willing to promote Spore because it has science in it and is therefore thought to be educational. It is not difficult to find quotes like this:  With its educational subject matter, Spore is the kind of game any parent should be pleased to find their child absorbed in” (Alderman, 2008).

Conclusions

Since all of the pre-release and release hype, not much has been written about Spore. Pretending to be good science and actually promoting accurate science are different entities, and many in the media will take superficial views. There is a good chance that the media writers also hold serious science misconceptions, so they don’t even know when something is inaccurate. Therefore, it is up to scientists and science teachers to help the public understand which products are good educational tools for promoting science education.

Perhaps the first assay we learned in science class was the starch test, where we dropped iodine on a substance, and if it turned “blue-black”, it indicated the presence of starch.

Now, as modern-day science teachers, we carry on the wisdom of generations of science teachers, and continue to avoid calling the positive result “black and blue”, as no science teacher wants students to associate bruises with white bread or potatoes.

The starch test has become such a common test, that I believe the term “starch test” should replace “litmus test” as the analogy cliché for social or political tests. (For example, Wikipedia states, “A litmus test is a question asked of a potential candidate for high office, the answer to which would determine whether the nominating official would choose to proceed with the appointment or nomination.”) How many non-science teachers even know what litmus is or what a litmus test is? Let’s start using analogies more people can relate to. [People would really start liken that (with an intended pun on the nature of litmus)!]

Today is the six-month anniversary of this blog. It seems such a short time ago, but alas, on June 20, 2008, my first blog was posted. This made me wonder, “How does one know if one is successful after just six short months?

To find the answer to this query, I did a search on blogs. I found no numerical metrics for success. Looking at the latest report from Google Analytics, I did see that more than 35 people per day have read this blog, and that this month alone, there were over 1,000 readers from 70 countries/territories.

The search for blogs about blogs (i.e. metablogs) yielded no numbers, which I viewed once again as evidence that collective wisdom can often be found in groups of people. The qualitative metric I did derive, however, from reading the advice of more experienced blog pundits was this: If a blogger enjoys writing about their interests, and some people are reading, then it should be considered successful. As far as this starch test is concerned, I judge this blog as a success, and I thank you for reading it.

But now on to science teaching and technology, which is the focus of this blog. In the living world, photosynthesis is one of the most important processes. Fortunately, Adaptive Curriculum has a free interactive activity that teachers and students (from all 70 countries/territories) can use to learn more about photosynthesis. In “Plants Needs for Photosynthesis” students conduct several investigations, where they can add or subtract water, light, carbon dioxide, and oxygen. The plant then does its thing (AKA: metabolism) for four hours.

After this, the starch test is performed to see if photosynthesis occurred. In the starch test, the leaves are boiled and then dipped into hot alcohol to remove the green chlorophyll. Next, the leaves are dipped into room temperature water. Finally, drops of iodine are placed upon the leaves. Through these discovery-based learning experiences, students are able to determine the conditions that are needed for photosynthesis to occur.  

Thank you to Adaptive Curriculum for giving us this free Flash-based activity, and for their support of this blog. And no matter what your starch test or litmus test for happiness may be, I wish you a happy holiday season.

To be sure the idea behind WolfQuest has merit, let children ages 10 to 15 become virtual wolves and learn about wolves and their habitat. But in production, the National Science Foundation (NSF) and privately supported free WolfQuest game is disappointing. I found it to be tedious and buggy (on my Macintosh). Just to be fair, I did induce my 11 year-old son to try out the game. By induce, I confess, that I paid him an hourly rate to try it out. He played for about three hours total. I will say that the game does have good 3-D graphics and when my 8 year-old son saw him playing the game, he was induced to be a wolf just for the fun of it–for about one hour. They seemed to spend most of their time hunting, which wasn’t all that much fun (lots of running, with some attacking). They never did get around to mating….

I do suppose that some children may become deeply immersed in this environment, creating their own online wolf packs and exploring aspects of wolf social behavior. And if a good percentage of tweenagers were motivated to do a couple of extra hours of science explorations, I suppose the NSF would be happy with the $508,253 grant they gave to the Minnesota Zoo for the project. (I don’t know the full budget but private organizations contributed quite a bit as well.)

But where is the science? You would think there would be a “for educators” or “for parents” description of the science that might be learned. I couldn’t find any descriptions like this on their web site or the downloadable manual. The developers apparently don’t think this is important, but yet the WolfQuest merchandise link was very prominent. So what did my sons learn? They saw some variation in wolf types as they created their avatar.  They also learned that wolves in Yellowstone National Park hunt elk and hares and perhaps that the life of a lone wolf is not that much fun.

It is not easy to criticize this project; it is much like in the movie Teachers (1984), where Alex says, “That’d be like $#*%ing on the Peace Corps!” It is far more PC to say, “Wow, this is nice, look at all the downloads they attracted!” or “Wouldn’t you rather have your kids play this?” I know I might come off as sounding “anti-wolf” or against conservation of natural habitats, but that is not at all my view. For instance, when I was co-author for the biology textbook, Biology: The Dynamics of Life (Glencoe/McGraw Hill), I introduced for the first time a chapter on Conservation Biology that was eventually copied by other textbook companies. I have also taught a Conservation Biology course in the National University when I was living in Costa Rica.

Besides the lack of fun, my problem with this game is with the lack of science education. Perhaps the goal isn’t science education. Oddly enough, the web page does describe one of the goals: “Gameplay will create a strong emotional connection between players and wolves, changing player’s attitudes toward wolves and habitat conservation in the real world.” First, I think this is a ridiculous statement. My children have “become” so many characters in video games, and I have not observed strong emotional connections form. Indeed if this was the case, in any Nintendo game I would insist my sons never become Wario and always become Mario! Second, I think this is a misguided goal; the idea of a good education is to develop an understanding of a situation to make informed choices. Our goal should be to help children understand species, ecology, and conservation and not to have their emotions guide their behavior.

The reviews are coming in about the new game SPORE, and they are less than inspiring. Along with its restrictive DRM policy and the weak reviews, I am not going to purchase this software for me or my sons. While I did use and write about Creator Creator, my writing about SPORE is not based upon first-hand use.

The review are in….

Chad Sapieha of The Globe and Mail writes: “…dull and repetitive play makes evolving your own species more frustrating than fun.”

Lou Keston of the AP press writes: “No single element of ‘Spore’ is revolutionary in and of itself. Each of the levels feels like a simplified version of a game you’ve played before.”

Matt Peckham, in his blog for PC World, describes it this way: “…the game’s still a few chromosomes short of a genome.”

Seth Schiesel of the New York Times, writes, “Beneath all the eye candy, most of the basic core play dynamics in Spore are unfortunately rather thin.”

Chris Kohler of Wired wrote about the top ten things he learned from playing SPORE. Number one on his list, Spore is kind of boring.”

And speaking of learning, is this a tool for science education?

While science was theoretically the driving force for SPORE creator Will Wright, the descriptions of SPORE do not indicate this will help people learn science. When the science is discussed it sounds more like misconceptions, rather than accurate understandings, are being fostered.

For example, notice how the science is described in these two reviews:

Thierry Nguyen of 1up.com states, “If you really need a quick one-line summary of what Spore is, I guess I’d describe it as ‘intelligent design via minigames.’”

Matt Peckham describes early parts of SPORE this way: “Consuming bits of matter builds up your DNA, which you can then spend on new parts available inside a simple design tool that pops up whenever you choose to mate.”

The notion of evolution as making choices, as deciding to come out of the water to be a land creature and therefore deciding what appendages to gain, and the thought that the more DNA you eat the more evolved are so wrong that I wonder why Will Wright considers this to be science inspired? Hopefully, the travel in outer space and the ecosystem building are more accurate. But for me, I am in no hurry to find out.

Adaptive Curriculum, describes its core learning segments as “Activity Objects.” This is, as far as I know, a new term that has evolved from other terms including “Learning Objects.” In case you are not familiar with the term Learning Object, I will describe this, touching briefly on its origins, and then explain why I think Activity Objects is a well-chosen term.

What is a Learning Object?

The term Learning Object grew from computer object-oriented programming, a paradigm of creating reusable and cooperating “objects.” As with programming objects, the generally accepted criteria for Learning Objects are that they are digital, cooperating, and reusable. Unfortunately, as so often happens in education, terms are used in so many different ways, they start being less useful.

From a broad perspective, a Learning Object is any instructional resource that can be combined with other resources. This is formally presented as “independent pieces of instruction that may be reused in multiple learning contexts” (Fernandez-Manjon & Sancho, 2002). To many of us, that is too wide a definition as almost anything can be considered a learning object.

Wiley’s (2000) definition—more useful because it is narrower—is as follows: “Any digital resource that can be reused to facilitate learning.” According to Wiley, “Learning objects are generally understood to be digital entities deliverable over the Internet, meaning that any number of people can access and use them simultaneously (as opposed to traditional instructional media, such as an overhead or video tape, which can only exist in one place at a time). Moreover, those who incorporate learning objects can collaborate on and benefit immediately from new versions.”

Friesen (2003) describes problems with terminology involving Learning Objects and makes a call for clarity: Using a term that make sense only in abstruse technical discussions, and that is opaque and confusing to practitioners does not make its potential benefits clear to teachers…. It is simply that innovations must be presented in terms that are meaningful for teaching practice.”

I think teachers need to be able to easily differentiate between online resources that are relatively passive (such as text based web pages) and those that have strong elements of student interactions. I believe that the term Activity Object is a term that will make sense to practitioners and will help differentiate online resources with strong elements of interactivity. There is a big difference between some current science articles versus cool science experiments online.

What is an Activity Object?

An Activity Object, as the name describes, is a learning module that puts the emphasis on active learning rather than just passively reading text or viewing images or movies. It is designed to compliment other instructional approaches.

I propose the following definition of an Activity Object: An Activity Object is an online digital learning module featuring high-quality student interactions that help to achieve narrow learner outcomes.

To be sure, the Activity Objects of Adaptive Curriculum feature engagements, animations, closures, activity sheets, and assessments, but these are supportive of the high-quality interactions. Of course, some may take the definition I propose and say that many online materials are Activity Objects. To me the question resides in whether or not it is a high-quality interaction. If students mainly read text or watch movies, even if they are answering some questions as they go, this just doesn’t rise to the level of being a high-quality interaction and should not be considered an Activity Object. I propose that we use the term Learning Object for those online materials that support learning but that don’t have high-quality interactions, and that the term Activity Object be judiciously used for learning experiences with high-quality interactions. Therefore, the resource with current events in Earth science can be considered to be a Learning Object but the science project, science activity, and interactions would be considered Activity Objects.
