For this post, I must first get you in the right frame of mind. We are spending the holiday break at our cabin in northern Wisconsin. It has been very cold so each morning when I get up I check our Ecobee to see just how cold it is. It was -27 this morning (this translates as it is probably too cold to get the car started). The Ecobee also posted a warning message which could be summarized as – your furnace is not working.
This is precisely the reason we installed this device. Most of time we would not be in the cabin and due to one issue or another the heat may not come on resulting in frozen and possible burst pipes causing all kinds of damage, etc. The Ecobee is “smart” (see my description of the data it collects on our heating and cooling) and sends us an email should there be a problem we need to address. Sure enough, an email arrived.
This system seems to work great unless the power is out which knocks out our wifi making the system pretty much useless. I would think the company could ping the thermostat and send us an alert that our protection system was offline. Anyway, it worked great this time.
The problem turned out to be a lack of propane. We have a contract that is supposed to result in our tank being filled without our intervention, but evidently there was an issue with getting this done. They explained that they had planned to fill our tank on the 18th. Their usage calculations evidently do not adjust for very cold weather. I am thinking this might be a long term problem so some discussions are in order.
One of the things I remember from reading Papert (Mindstorms I think) was his explanation of different ways of understanding. He claimed that computation offered a different way of understanding. One example which I think was from the same source concerned the understanding of circle. The demo goes something like this.
Most of probably remember the definition of circle – a closed plane figure consisting of all points equidistant from a point. The ability to produce this definition does not really mean we understand it. He proposed the following demonstration (I hope I am remembering the source appropriately). You can turn this definition into a program (logo).
This demo was generated in Blockly. If you follow the code, you should be see how the code expresses the definition.
The theory and application of mastery learning has long been a professional interest. The origins go back to the 60s and some crude variants to even earlier models of instruction/learning. I have also presented some of these ideas in my educ psychology classes for years as an alternative way to understand learner aptitude (time to learn). In recent years I have added a component focused on the Kahn Academy. My students find Keller and Bloom to be what they call “theoretical” (even though there were clearly applications of each), but they are intrigued by Kahn. One student wanted the link today because he wanted to try the modules on biochemistry.
I have watched with interest the evolution of the Kahn Academy. By evolution, I mean the earliest version did not promote the flipped classroom (a different use of class time) and mastery learning (very similar in my thinking to Keller’s PSI). I wonder about this evolution. Is what we see now closer to the original “grand plan” or have those developing this system found that what was being developed were great ways to implement existing “big ideas”?
I do discover something new each time I prep for my presentations and visit the site to review the features. This time I discovered the separate content on programming. Educators (e.g., Maker movement) have been rediscovering programming and the Academy offers an interactive experience based in Javascript.
I struggle with the concept of a new “maker culture”? I really like the concept as suggesting new educational options, but I struggle with the assumption that makers are “technology-based”. There are lots of ways to make things that do not include programming or robots or a soldering gun. Nothing wrong with programming or construction of technology devices, but we learn by making other things as well. We make something when we write. Writing and programming share the use of a symbol system to create a product. Writing, which also benefits from the use of technology, is not among those processes included by those who claim to belong to the culture of makers. One concern that I have with the popularized version of being a maker is that the examples given will not be of interest to all students or all students. I would prefer all students have the opportunity to pursue a self-identified passion.
How educators are encouraged to apply technology is somewhat schizophrenic. Educators seem caught between two platitudes. On hand they are encouraged to recognize that “it is not about the technology, it is about the learning” (a common educator twitter admonition). Of course, makers seem to argue the opposite position. Are we back to teaching a version of computer literacy or the concern that we must program or be programmed?
Perhaps students should be offered options. I mean options beyond electives such as art, music and athletics. As I have encouraged expanding the allowable electives, I have proposed developing and studying school gardens or habitats. Many may be surprised that there are such things as school gardens, but these activities are more common than many might think and have a very similar literature. One of the realities of involving all students in any supplemental activity is that students seldom accomplish more (note the plural students) than develop an awareness of the content area. I do not think this is what is intended. It makes more sense to me to find ways to allow those students with a real passion for such topics to explore in depth rather than provide all a superficial exposure.
I would encourage close reading of the following two reviews (the first is an analysis of logo programming and the second of school garden projects). These are reasonable reviews of the benefits of teaching programming (logo) and gardening. Just what kind of transfer has resulted from such learning experiences?

If you use the Chrome browser and Google services, you are likely familiar with the app launcher. The launcher is available from the square of blocks appearing in the header and provides easy access to the services Google must think are used most heavily.
The limitation with the launcher has been that these are not necessarily the subset of services that you use and the apps within the two sets of nine apps are not necessarily organized to meet your needs. It is now possible to customize both the Google services and the order of these services using App Launcher Customizer.
Once you add this extension to Chrome, the app launcher can be configured.
Selecting the “configure” link gives a user access to icons representing Google services and the services presently available from the launcher. You drag to add services and to reorder where they will appear in the launcher.
For example, I frequently take advantage of Google Scholar in the work I do. I can add this service and position it for easy access when I open the app launcher. This is a must have extension for heavy Chrome users.
As far as the big technology companies go, I am probably more a fan of Google than any other company. This admiration reflects how I value their products, but also how I value their way of going about doing business. Just for the record, I do not consider myself a freeloader. I pay for Google services (Google Music and general storage space) and I have purchased severely overpriced products (Chromebook Pixel) just because I wanted a particular development effort to move forward. My point – I do not expect technology companies to provide me services for free and this not the reason I support this company.
Google is obviously changing, some would say maturing, and a possible interpretation might be that they have become more focused. One tactic in implementing a more focused approach has been to cut several services. At least some number of individuals will have been users of these services and this will cause frustration.
Recently, I encountered a campaign to reconsider changes made to PicasaWeb. This service allows Google users to store photos online (a reasonable number at no cost and more storage for a small fee). I had noticed this change in that my efforts to access images I had stored as Picasa folders resulted in redirection to Google+. In my opinion, Google wants to build up Google+ as an alternative to Facebook and is making efforts to position Google+ as a kind of hub for multiple services.
The post (ironically on Google+) was brief, but it seemed to urge those who use PicasaWeb to encourage Google to maintain this service and to maintain it separate from Google+. Those who agreed were urged to + the post. Given the history of Reader, I would not be optimistic. Felix Binsack, the originator of the campaign, does have a point in indicating that he paid for PicasaWeb and I suppose while the time period covered by the payment was limited, you put work into a paid service assuming it will be continued.
I write mostly to inform those interested in the educational uses of technology and I think PicasaWeb has a number of important and useful features.
I like the connection between software on the desktop and storage in the cloud. Google provides free software you can download (Picasa) and this software can be used to take photos off your camera, organize photos, and upload those you want to store in the cloud and possibly offer to others. You can work entirely in the cloud, but if you work with hundreds of photos at a time, I think this local software is helpful.
Picasa is cross platform. I like iPhoto as well, but when you write for a broad audience (teachers) it is important to offer tactics they might apply no matter what the hardware provided for their use.
The desktop software allows flexibility in location of images on the computer. Picasa takes an approach different from iPhoto. You can store your photos where you want on your computer and still work with them using Picasa.
My experience with Google+ had not included a lot of activity using the built in photo tools. I admit after a little exploring I was more impressed. Google+ does allow the organization of photos in folders and allows the sharing of photos with a designated circle (or the general public). The organization, annotation, and sharing of photos are major issues for me when it comes for the educational potential of digital photography.
Here is a brief explanation of how to organize Google+ photos into folders. On the iPad, the process of organization would work something like this. While viewing a photo, select the “gear” icon and then select the “copy to folder” option from the options you are presented.
You will then select an existing folder or be allowed to create a new folder.
The process from a computer works a little differently. With a photo selected, you should have access to a “More” menu and you select “add to a folder”.
Clearly, creating folders and adding images to folders can be accomplished within Google+. I will also accept that the batch processes available from Picasa would make the process of organization more efficient.
The generation and utilization of educational content has long been a personal interest. We have been lucky enough to have a book available since the mid-90s. We split with our publisher a couple of years ago because we wanted to explore a smaller and less expensive book in combination with more online content. We were able to implement our plan by securing our copyright and updating our material as a Kindle ebook and online content.
We selected Kindle because it was cross platform with the iBook being limited to the iPad at that time. However, the flexibility of the iBook is attractive and iBook Author appears to be a great platform for generating content.
While I really like the iBook author platform, I do not get the Apple ibook plan. It does not seem suited to those of us who write for higher education courses because while you can expect students to have some type of device, you cannot really assume it will be an Apple product (now iPad or a system running Mavericks).
There is also the matter of price to the reader. I did a quick comparison of Kindle and iBook prices for the books I have finished within the last two months and the Kindle version is always a little lower. While I do most of my reading on an iPad, I read none of these books as an iBook.
Making thinking visible – 18.96, 19.99
Invent to learn – 9.99, NA
Reign of error – 11.99, 14.99
Teaching minds – 14.55, NA
One Click – 7.99, 9.99
The everything store – 10.99, 10.99
The mushroom hunters – 11.84, 11.99
The circle – 6.50 6.99
Higher cost and fewer hardware options for experiencing the content seems a bad combination to me.
A book that goes beyond text must be where Apple sees this going. Clearly, the present Kindle books are far more limited as far as this potential goes. However, none of the books I just listed here would have benefited from a more flexible format.
The kind of product that would really take advantage of the iBook format would be very expensive to generate for the college market. Multimedia content requires more sophistication involving multiple experts and typically requires a careful approach to the acquisition of permissions. It was the issue of permissions in combination with our desire to generate a far less expensive book that let to our break with our publisher. Even if an individual could generate a more complex product there are always those issues that require lawyers in a commercial venture. An approach that primarily relies on text is just easier to generate. Professional help such as a good editor can greatly improve the work of any author, but that is about all you need with a Kindle book.
Our plan is to revise our present book this summer for both platforms. If you tell yourself this is about exploring and not about money or time, it is sufficient to enjoy the creative process. The plan is to offer a Kindle plus online content version and an iBook version that incorporates more of the content we presently provide online. We will see how it goes.
