Mobile Computing

Mobile computing refers to the use of any kind of computer in a moving environment. The motion may be of the device itself, as in laptops, palmtops, wearable computers, and mobile phones; or it may refer to the dynamics of the computing process, as in digital cameras, podcasters and MP3 players. Mobile computing devices generally use wireless technologies such as LAN, Wi-Fi, GPRS and the more recently introduced MAN.Mobile computing can be broadly classified into two categories – portable computing and mobility computing. Portable computing actually refers to wired communication. Portable devices themselves are movable, but in order to access them one needs to connect them to a network port. That means, portable computing devices can be carried to wherever there is a network port available. Mobility computing is also called simply mobile computing nowadays. This is true wireless communication. Not only are the devices movable, but they can also be accessed from almost anywhere. Today, portable computing is almost on the verge of extinction; mobile computing has made its foray into almost every aspect of human life.

The first usage of mobile computing devices was perhaps in vehicles. Speedometers were among the first devices to get computerized. Almost every modern vehicle has several mobile computing devices under its dashboard. Cell phones are another rampant proliferation of mobile computing today. Every single cell phone is a computer in its own right. With the advent of wireless technologies, it is also possible to access the Internet through cell phones. Blue tooth has brought cell phone users closer than ever before and has facilitated data transfer within a stipulated area. Another brilliant advancement in the field of wireless technologies is the Metropolitan Area Network, or MAN, which will allow vehicles and cell phones to remain in communication with each other forming a network probably much vaster than the internet.Today, mobile computing is a boon to people on the move. It can be used for checking mails while in transit and even carry out transactions and businesses. Services like SMS (Short Messaging Service) and MMS (Multimedia Messaging Service) are targeted towards the younger generation to remain in contact with their colleagues and friends. During sports events, mobile networks keep users informed of the goings-on.

However, critics are concerned with the intrusion of privacy that mobile computing creates. Several members of the younger generation are turning into ‘gizmo freaks’ and becoming almost addicted to their mobile computing devices like watches and cell phones. Some of these devices which work on infrared technologies can also pose potential health risks.Yet, mobile computing has become an indispensable extension of technology today. It is definitely here to stay.

The Fine and Performing Arts & Education

Education either functions as an instrument which is used to facilitate integration of the younger generation into the logic of the present system and bring about conformity or it becomes the practice of freedom, the means by which men and women deal critically and creatively with reality and discover how to participate in the transformation of their world. (Paulo Freire)I see too many public service commercials-today-exhorting us to support the Performing and Fine Arts in public education. We, as a nation, have evidently become so low-brow, or unsophisticated, that we can no longer see the need for Art education in our schools. So now, we have our children pleading with us, on television commercials, to keep Art education alive. This is a sad state of affairs for us and our children, because art is what truly separates us from the beasts and allows us to rise above the mundane drudgery of life. As many others, I believe art should be at the center of education and not just because it’s good for us. Art stimulates a child’s cognitive and affective domains, as well as their motor skills, which leads to learning, discovery, creativity and motivation.Academics are very important, of course, but too often they only stimulate a very small portion of the student’s mind and heart. There are three, basic domains of learning: the Cognitive (mind), Affective (emotions or feelings) and Motor-Skills (hands-on). These three domains are key to our thinking/reasoning, learning, problem solving and creating. A healthy mind (Cognitive) is capable of taking in, retaining and processing information, which can then be applied, if retained and used, to the individual’s life. Emotions and feelings (Affective) are closely connected to an individual’s learning, because they aid in retaining and applying information, as well as stimulating the desire to learn more. Seeing, hearing, speaking, the ability to write, walk and run are all part of the individual’s Motor-skills. Without these three domains, learning, needless to say, would be impossible. Reading, writing, math and the sciences stimulate the cognitive and motor skills domains quite effectively, but the affective is too often short changed.If we think back to our school days, then we should be able to remember that the memorization of facts and successfully spitting them back out on tests was our main concern as students. This is very much a part of the learning process, and I’m not denying that, but where does the Affective domain play a significant part in this teaching process? In much of this way of learning the affective is absent, and-therefore-much of the educational material, which has just been learned, has no real application in the individual’s life and is forgotten. I remember very little about higher level math, the periodic table and scientific jargon. Why is that? It didn’t relate to my life nor touch me in a deep way. This is not to say that I, or anyone else, shouldn’t have taken math and science classes, but what I am saying is academics are less effective than they can be, because they tend to ignore the Affective domain.

I contend that the Arts use all three domains effectively, and they can-therefore-stimulate the student to apply, as well as retain, what they’ve learned. Creativity is key in this process. The Performing and Fine Arts have a distinct advantage-educationally-in their ability to allow students to create as they learn. In painting, students are in the process of creating at the same time they’re mixing colors and learning brush techniques. The same applies to sculpting and photography students. Many middle and high school music directors are-now-using computer programs to stimulate their students to compose as they learn to play and sing. Dance and theatre programs are examples, as well, of applying skills as their students learn. This artistic, educational process employs the cognitive and motor skills domains, but it also stimulates the affective. The art student experiences the sense of joy and satisfaction that comes from successfully learning, and then being able to immediately apply this knowledge in a very personal way. The Arts can enhance a student’s ability to express their emotions in a very positive way. These students have ownership of what they have learned and are able to express this ownership through creativity. The Performing or Fine Arts student is motivated-educationally-beyond just memorizing facts and passing tests, because they’re using their newly-acquired knowledge to express what lies deep in their heart and mind.Surprisingly, the arts and sports have much in common, educationally. The basketball or football player, as well as the long-distant runner, learn their skills while applying them. The learning of physical techniques and immediate application reinforces the athlete’s desire to learn and perform even more. In team sports, such as football, baseball and basketball, the student athlete learns to work with others to produce a product, or team. The young athlete learns that the whole, or team, is greater than the sum of its parts, or players, as do dancers, actors, singers and instrumentalists. As in performing ensembles, these young athletes experience the joy that comes from accomplishing something special with others. They learn, in a very intimate way, responsibility towards others and that the team is dependent on the very weakest athlete, as well as the strongest and most gifted. There’s really very little difference between a football player and a band member, when it comes to being responsible and understanding that it takes everyone-involved-to be successful. This is such a valuable and wonderful lesson, and it is learned primarily, through the affective domain.Educational collaboration between artistic disciplines is a great way for young artists to learn while they create. The pairing of young instrumentalists with dancers and visual artists, or actors with singers, can open up a whole new world of artistic exploration, discovery and creativity. These collaborations can become a great vehicle for learning and motivation, as any arts teacher who has experienced this process will testify. The educational process becomes more important than the outcome, or testing results, because it is in the process of exploration, discovery and creativity where learning really occurs. The educational outcome is secondary, because it is only used, in this case, to measure curricular goals. The motivation for and enjoying of learning comes through the process of collaboration, exploration, discovery and creating.In academia, the emphasis-today-is placed more on the outcome, or testing and grades, which, in my estimation, is a huge mistake. Academic instructors could learn much from their counterparts in the arts. The government and its politically motivated, educational policies, of course, stands in the way of any successful, corrective change to academic teaching methods. Political agendas, such as, “No child left behind” are meaningless and worthless to students and teachers, because they’re not concerned, as they so hypocritically claim, with the success of the individual learner. Instead, these agendas are merely an attempt to soothe the fevered brows of unsatisfied constituents.I will agree with academic teachers that their process seems to be more set in stone than with the arts, and the only real way they can measure educational outcomes is through testing. There has to be a way-however-to allow a math, science, English or history student to become more involved in the process of learning. English teachers have a distinct advantage, since they could use writing essays and poems to instill a sense of ownership in their students. Their students-then-could use their essays and poems to collaborate with young composers, actors and dancers, as an example. Even though it would be difficult, science, language and math teachers could also seek these same avenues for educational exploration, discovery and creativity, which would-then-hopefully-lead to a student’s retention/application, ownership and motivation. This, of course, will be impossible, as long as we allow our government to force academic teachers to teach-solely-towards the outcome, or “standardized” testing.American students, every year, fall farther behind their counterparts around the world, academically and intellectually, while their parents and teachers continue to buy into the educational propaganda, which is spewed out by the American-political machine in Washington. Every year, Art education becomes less and less important in our schools, because of it’s effectiveness in producing students who can think, reason, question, learn and create. Realistically speaking, Art education may be perceived as a threat to those who run this country and desire a race of middle-class, mindless, unquestioning and unsophisticated robots.

Education is the responsibility of the parents first and foremost, and if parents aren’t capable or willing to fight for their children’s education, then I guess America is doomed. If I were a parent-today-there would be no way I could allow my child to be intellectually molested by our current, public-education system. My child would either be home-schooled, at best, or in a private education system.The Roman Empire was one of the greatest and long lasting nations in the history of the world, and yet, as the Roman government declined, then so did its human values and arts. There is only one piece of music remaining, one mere fragment, after one thousand years of Roman culture. Rome literally disintegrated from within, because of a corrupt government and decaying society. The United States is less than two-hundred and fifty years old, and we’re already starting the lingering slide into governmental corruption, cultural ignorance and decay. Perhaps, it’s too late to save our society, but if it isn’t, then it’s time to start rebuilding what we have allowed to be torn down for the last one-hundred and fifty years. If it isn’t too late, then we must begin to rebuild our values and education system. Our values and education system may not have been perfect, in the past, but they were worthy of being fixed, properly.Most successful, world cultures, throughout history, have been measured by the quality of their philosophers and artists far more than their forms of government and technological advances. If we disappear as a nation, in another century or so, what will we be remembered for? What will be our legacy to the world?Art does not solve problems but makes us aware of their existence. It opens our eyes to see and our brain to imagine. (Magdalena Abakanowicz)In my estimation, art is an integral part of being human and-therefore-is integral to human education. If we die to our affective inclinations, then we cease to be human in any real sense, and the results of this can be seen on MTV and its “Hip-Hop” generation. Money, material objects, self-absorbed egos, low-life affections and brutal power will never make us more human, if anything these extrinsic motivators will simply and affectively dehumanize us. “The one with the most toys in the end,” loses! Art education can help us to see ourselves, the world and-yes-God more clearly. We are more than flesh and blood, and our affective, as well as cognitive, attributes are exhorting us to remember this truth. The arts should be at the center of our children’s education, and our children shouldn’t have to plead with us to give them what they need and desire!
