Leonardo Reflection

In my years as a sixth grade teacher, one of my main tasks at the beginning of the year was teaching kids the definition of culture.  Many had heard the term, but definitions eluded the students.  My plan was to break culture down into a series of parts: food, clothing, shelter, language, economy, several others, and of course, technology. My definition of technology often was difficult for kids to fathom as it encompassed all the different technologies that a society possessed, some simple and rudimentary like the knife or fork we use to eat with, while others were world-changing like the internet.  The author of this book divides history into several key periods, each defined by the different way technology and culture were interwoven in these different eras.   He looks focusses extensively on the world changing technologies that emerged from these periods, the cultural forces that created them, and the effects they had on the culture of that periods. 
            Chapter 1 focuses on the period of Leonardo da Vinci himself.  This period was defined by court patronage.  Patronage was the process where the wealthy and powerful would sponsor an artist, scientist, or both (as in da Vinci’s case).  This sponsorship could be for many reasons.  It could be to produce gain for those patronizing someone, or it could be just a way to sponsor a talented young individual as she, or more likely in that time period, he would use the talents they have.  This is the format that allowed Leonardo to produce the wide variety of things he did in both art and science.  The variety of his achievements is a good example of what drove technological advances in that time period.  In the patronage system, what the patron wanted would drive the direction of the technological advancement.  This system will surface again in later areas, but is pretty simple.  If I’m paying you, I have say in what you work on and how those developments are used. 
            Chapter 2 described the Era of Commerce.  This era was defined by traders and trading companies.  It was discovered that there was tremendous profits available in trading.  The key was to find something that was cheap and plentiful and thus cheap in one location, and transport it to a place where it was rare and thus more valuable.  Our class presenter characterized this period as commercial but not industrial.  The things being traded were not being produced but were rather raw materials and commodities such as sugar, slaves, tobacco, cotton, and even tulips.  Technology of this era focused on allowing these traders to function in the most timely and efficient way possible.  It also shows the diversity of what qualifies as technology.  The aspect of this period that focused on building better ships and navigation tools is a fairly obvious example of technological examples.  However, the development of the trading systems, the commodities houses, and the banks particularly in the Holland were examples of other new ideas that show the less obvious side of technology.
            Chapter 3 chronicles the period often described as the first industrial revolution.  At the beginning of this period most people were still living an agrarian lifestyle.  However, as new inventions allowed the amount of food needed to be produced by a smaller number of people, combined with the new technologies such as the steam engine allowed the development of the first factories.  This period was most prevalent in Great Britain as they had all the right pieces to make this new system function:  iron, coal, and water power were readily available, numerous colonies to provide raw materials not found at home, and a large population freed up for factory work by the technological advancements in agriculture such as the seed drill and cotton gin.  The factory system was able to produce goods faster and cheaper and was built on the premise that efficiency increases profits.  While several business flourished under this model, other ancillary enterprises sprang up around these factories as well.
            Chapter 4 was a natural next step in the progression.  As these factories were reliant on raw materials that often were not located near the factory, both the acquisition and maintenance of empires as well as improvement of transportation methods would drive this period.  The large factories were predominantly in Europe.  These European countries relied on two things from their empires, cheap raw material and a captive market for finished products.  Also during this time the steam engine was converted from a means of powering factory machinery to a means of faster transportation through railroads and steamships.    These new methods of transportation drove this era as they provided cheaper and faster transportation of raw materials and finished products, but also provided for fast military transportation necessary to maintain order in growing empires.
            While many people prior to the era chronicled in chapter 5 may be referred to as scientists or engineers, they were likely given those titles after their accomplishments, not as a job title.  That changed during the second industrial revolution.  While the patronage system did have a little sense of being employed, it wasn’t the same.  This was an era of corporate industry driving technology.  Companies acquired technology in many ways beyond those developed by their employees.  This was the beginning of the relationships between universities and corporations.   Companies also purchased technologies or bought up competitors to acquire their technologies.  This is a practice still alive and well today.  This was also the time where industrial chemistry became more prominent.  Synthetic materials began to replace natural ones, often outperforming natural products and for less cost.
            Chapter 6 was on Modernism was one of the harder chapters for me to comprehend in reference to the rest of the book.  Each previous chapter seems to be charting a course straight through history with the way technology changed culture and the way culture changed technology.  Modernism seems to take the book on to a bit of a tangent that seems to dead-end.  The modernist movement makes use of technology but this era seems to be more about architecture and ideas than about the hard technologies described in other chapters.  Maybe this was the author’s purpose.  Many previous chapters had described ways that technology had changed culture, but modernism represents a shift in cultural beliefs that isn’t forced by technology but rather a result of technology.  What is ironic to me is that these idealistic and left leaning ideologies were fostered in countries that would soon be led in and entirely different path by far right wing dictatorships.
            That leads us to Chapter 7, The Means of Destruction.  While war and military purposes have always driven technological advances, this was more true during the period leading up to World War 2 and the long Cold War that would follow it.  Leonardo himself was employed for a period of time to develop military technology for his patrons, but never on the scale seen during this period.  The Manhattan Project was a key example the author used to show how military objectives drove the top scientists, universities, and corporations to work together to achieve military supremacy.  Post World War 2, this continued with the development of new technologies such as the transistor and eventually the internet.  Another example that strikes me that the author didn’t mention was the Space Race.  As a history teacher, I had often taught this theme of how military needs can drive technology and how that technology developed for military purposes would often lead to better technology for the regular man and woman.  While this can be true and often is, the author pointed out how this military driven mentality can hold back technology that would benefit society as a whole.  This discovery was one of the most striking for me from the book.
            Chapter 8 takes us more into the modern age with the idea of technology creating a more global society.  Mass media, satellite relays of TV, and the internet all act to bring the world culture closer together.  McDonalds spread world-wide was highlighted as an example.  It reminded me of a college professor commenting in the early 90’s about how US cities had become so much the same, same restaurants, same stores to shop in, etc.  Today that is being said about cities world-wide.  The internet and its origins were also a focus of this chapter.
            Chapter 9 honed in on some major problems technology has created and is yet to solve.  Many new technologies still run on old sources of energy.  Just think of how many things we now use that plug in and how they all still depend on the almost ancient technology of burning fossil fuels to produce that electricity.  We’ve made a huge technological apparatus standing on the fragile and unsustainable base of fossil fuel electricity.  This will have to be corrected or we are in for a nasty fall.  Also the tremendous amount of information online creates tremendous security concerns.  Two movies strike me for expressing these concerns: Enemy of the State from 1998 and The Net from 1995 both chronicle the dangers that powerful new technologies pose… and they are both more than a dozen years old.  Far more happens online now then when these movies came out. 
            Chapter 10 summarizes the books and  a few key concepts struck me.  Technology has always been “shrinking” the world.  From the Dutch traders, to steamships, to railroad, to telegraph lines, to fax machines, to the Internet, many of these technologies have sped up the time it takes to communicate and travel over greater distances.  The factory system tied parts of the world closer together, first in forced ways through empires, and now through the global economy.  The second key point that came out often throughout the book is how technology is both a force and a product of change.  Back to the very beginning of my reflection where I commented how technology is a part of culture.  However it is a unique part, as it can have such profound effects on the culture, while it can also be a result of cultural change.  Sometimes it can be difficult to identify whether people changed resulting in new technologies, or if technology changed thus changing the people.  Either way, whether for better or for worse, one fact stands above all -  technology and culture always have been, are today, and will be in the future infinitely intertwined.

Visual Learning

The move from education being in a classroom to online will hinge on the success of visual technology.  I’ve seen many online class formats, but I would contend that none of those will be truly as engaging as a real life classroom unless there is extensive use of visual learning.  I’ve seen online class formats where everything is based on students having to read and write information.  Those may work for those very committed to learning that topic, or those who learn well with that format, but this will not affective for the masses.  Students have always benefitted from visual learning being integrated into the classroom, and this will be even more critical as more courses are offered in an online format. 
            In going through the online book, I noticed that for me the most intriguing parts were when the instructor was interacting with a group of students.  The part where it was just her talking were not very engaging or informative.  This too makes me wonder if learning in an online environment can match the classroom  There are many ways to interact online, but I’m not sure they will ever match the effectiveness of personal instruction.  However, I also believe that both in-person and online instruction can be very effective or very ineffective depending on how they are conducted.  The skill of the person designing and delivering the lessons will continue to be far more important than the medium used to deliver them.
            The above point is almost moot, as online education is here to stay and will only continue to grow.  That is where I see it as part of my job to help assist and lead those delivering lessons to do so in an effective manner.  The use of visual learning will be a key part of that.  Today’s students have grown up with screens being a major part of their lives, so I can’t help but conclude that they will be more visual learners than previous generations.  Delivering content visually in an effective method will be very important. 
            I see a great deal of potential in the use of video sharing programs such as YouTube.  Again, Google has done a lot right in how they have given some options to the users in terms of how videos can be shared.  However, I cannot overlook YouTube’s greatest obstacle for schools and that is the presence of material that is not only non-educational, but highly offensive.  It took less than five minutes and typing “Naked Woman” to hit numerous sites that would be completely unacceptable in a school environment.  The difficulty is that the way YouTube works, it is only possibly to block or unblock sites based on specific URL.  This makes the task impossible for those managing those filters.  While I’ve also seen all those who say we should just toss out the filters and teach responsible use, as a school we still have an obligation to parents to provide at least some level of security for their students.  I did discover in doing a little research tonight that YouTube does offer a safe mode, which may offer us a way to allow certain URL’s while blocking the inappropriate material.
            That issue I do believe will find a way to be solved as more and more schools are looking for ways to offer fully online (or blended) education opportunities.  Another major consideration as schools move towards more online education is the increased hardware demands that video streaming places on a machine and also the infrastructure the supports it.   To conduct video learning, quality webcams, microphones, and video cards are necessities along with more RAM and faster processors.  Also, wired or wireless networks have to have the external and internal bandwidth to support these high volume videos.  At least currently, these things are extremely costly and would be cost prohibitive to many districts, especially those in the many rural areas currently unsupported by even broadband.  These same areas would probably be some of those to benefit the most from online education. 
            It will be very interesting to see where this goes in the next several years.  In some ways the ability to conduct education at a distance using these visual tools is already here.  Many schools are already doing it, but they are having mixed success (which in fairness all schools do.)  Some of the above issues I’ve raised are parts of those struggles, but there is also the accepted definition and practice of what going to school means that will need to change.   Technology will grow and hopefully things like bandwidth and equal access will continue to move in the right direction.  Even this week the FCC announced that they may shift as much as 8 billion dollars from subsidizing phone service, to beefing up broadband access for schools through the E-rate program.  Those hurdles are large, but they will be nothing compared to the hurdles of changing peoples’ attitudes and beliefs about what going to school will look like.

Reflection on Social Bookmarking and Networking


While last week’s items, Google Sites and Google Docs, were both very familiar to me and things I had already been using in education, this week’s topics were voyages into the unknown.  I’ve heard a lot about social networking and social bookmarking, but I have never really taken the time to explore them and consider how they could be useful to me in my job or in my life.
            My experience with Diigo was an interesting one.  I had been exposed to social bookmarking previously as a way to get your bookmarks to travel with you, rather than being tied to your machine.  I never really embraced this as it is very easy to add to favorites, and I don’t work on that many machines.  In using Diigo, I found there is way more to it. 
I have to admit that at first I was turned off by the “so much more” factor.  I sometimes get frustrated with software that attempts to do everything and thus complicates what might have been a useful resource.  When I first got into Diigo, I was frustrated as I was challenged to learn all the things it could do.  This seemed to get in the way of the original idea of storing bookmarks.  However, after spending some time with it, I found the “social” features of it actually will make it far more useful.  While I never found a need to save my bookmarks, I really am intrigued with the possibilities that it offers for creating an online community to share information. 
One of my jobs is to lead our district staff forward both in the area of educational technology and in the education of students at the middle school level.  I was able to use Diigo to create groups for each of those areas.  Through Diigo, I’ll be able to share sites and articles on these topics, while my staff will be able to do the same.  One of the biggest challenges is there is only so much time where we can all meet and discuss these important topics.  This will allow staff to participate in this discussion when it is convenient for them. 
I do still have concerns that the amount of information can be so overwhelming.  I already feel like I have so little time to consume the information, let alone act upon it.  There are so many different things that great schools and teacher do, that it can be overwhelming.  It is so important, especially in this information overload era, to remember the important saying: No one man (or woman, school, etc) can do everything but don’t let that keep you from doing something. 
The second part of this week’s lesson was using Twitter and numerous articles on social networking.  Reading all the information on social networks, the wide variety available, the great education uses, and the concerns about student privacy and safety are very unsettling for me.  I see social networking as having such great value in education.  However it poses so many questions I feel I need to solve:  What is the best site out there, how will students privacy and security be protected, do we need permission for students to use it, what do we do with parents who won’t give that permission, what policy changes need to be made, how do we train staff how to use it, how do we provide the technology in school and at home for students to use this, where will those funds come from?  Those questions alone, not to mention the numerous other duties that consume our time, are the key reasons many schools make like Nancy Reagan and “Just say no.” 
I’m very grateful for this course as it is pushing me in some directions I’ve always wanted to go, but haven’t had the impetus to get going.  I do feel unsettled by all this, but I do also see a course of action.  These problems need to be solved one by one.   The challenge now will be to figure out what step to take fi
