Evaluating the effectiveness of e-learning



Perhaps at this point, e-learning is still a very fluid concept, considering that the world is not at the level whereby e-learning is genuinely widespread yet. Currently, we define e-learning as learning that is facilitated by the use of digital tools and content, and that it involves interactivity between the learner and their teacher or peers. Institutions hope to provide convenience and flexibility to learners while improving performance and access with e-learning. However, preparing and developing e-learning materials is a costly and time-consuming enterprise, without being able to predict the take-up rate and genuine benefits before such programmes are launched and tested.

Furthermore, e-Learning is touted to develop the skills and competencies needed in the 21st century to ensure that students have the digital literacy and skills requires in their discipline, profession or career. However, at a closer look, perhaps some may realise that this is a chicken and egg situation. Is the student first digitally literate, competent and skillful, consequently being able to fully reap the benefits of e-learning, or is e-learning supposed to train them in this area of digital competence throughout the process of learning about other main topics?

The former seems to make more sense as e-learning would logically be extremely difficult for anyone who is not digitally competent. The process of e-learning should allow users to learn through digital tools, and fully exploit the digital medium for its benefits (which would only work if users have the capacity to use them), instead of expecting them to pick up digital skills while also absorbing the main content of what is being communicated through the digital medium.

A feature of online instruction over paper-based learning processes is the ability to employ multiple media types to present ideas and concepts. These include the playing of games, sharing of videos, simulation, and much more. However, how close does the ideal of online learning match against the reality of delivery? Through personal experience, the blended approach which involves both face-to-face, as well as online interaction and learning is the most effective in matching the ideal of e-learning to the reality of delivery.

In secondary school, my first encounter with e-learning was News In Class by Channel News Asia. At that time, my school used the programme in both English and Mandarin, with the aim of getting students interested and talking about local and international current affairs. This blended approach of presenting digital media as well as discussing issues face-to-face, as a class was rather effective (to me).  It created tasks for us to undertake as students – which is thinking critically about current issues and presenting our thoughts to the class in a discussion. This form of interaction then provides us with an experience, which is likely to lead us to the desired new understanding.


In polytechnic, we also experienced e-learning as part of the blended approach for the module – Basics of Entrepreneurship. In that module, students were required to play a game (similar to Cisco Aspire as shown above) to experience the challenges of running a business. The fundamental idea of the game is to simulate the whole process of starting and financing a new company. Players go through this process as an entrepreneur and as an investor. As an entrepreneur, players would have to find their own business opportunity, communicate ideas to other people and negotiate funding with investors. Successful players would obtain (fictional) funds to start their companies. While taking the role of an investor, players learn to recognize good business opportunities, to mentor and critique entrepreneurs, to make difficult choices about which companies to finance, and to negotiate terms with entrepreneurs.

In addition, we have class discussions every week to sharpen our understanding of the entrepreneurial process by discussing and analyzing business problems that we faced as entrepreneurs in the game. This method was effective for me as the approach allowed for interaction with my tutor and peers both online and offline. Furthermore, e-learning is more effective when there is a reason or motivation for students to undertake an educational activity if the learning is to be memorable and considered valuable. From my perspective, this entrepreneurship game provided students with an interesting context or scenario, which is able to assist the activity to have meaning. With the freedom to fail, students can see the importance of business skills in the real world through the game and gain valuable experience without any fear of financial losses. Therefore, it allows the learner to pass through many levels within the cognitive domain of Bloom’s Taxonomy, from remembering to evaluating.

All in all, I find that e-learning is the most effective when it involves a participatory design and implementation approach, where the e-learning system is a two-way street, allowing ongoing communications between educators and users. If done right, e-learning has the potential to produce great results by decreasing costs and improving performance in terms of accelerating knowledge development and learning as well as promoting critical thinking.

Taking Businesses Online

I used to think that e-business and e-commerce are just interchangeable terms to mean the same things, but now with a deeper understanding of this concept, I am able to tell them apart. By formal definition, E-business is the function of deploying technology to maximize customer value while E-commerce is the function of creating exchange, for example buying and selling, over digital media (Kalakota and Robinson 1999).

Ever since the Internet took off and stabilised as a popular media, Internet technology went from being a good to have in businesses, to the actual cause and driver.  One of the theories that I actually find very apparent through my personal experiences with online businesses is that a main goal of doing business on the Internet is to expand the market reach of the business and to obtain a much more eclectic customer base, without geographical barriers. Furthermore, doing business online creates more flexible outsourcing alliances between companies, which lower costs.

However, not all entrepreneurs are skilled enough to use the Internet to their advantage, which prompts me to reflect on successful and unsuccessful online businesses, and the reasons for their uprising or downfall.


The success of top online retailer
-->
Net-a-porter is a luxury fashion retailer currently valued at £350m. In the 90s, women only bought clothes they were able to see, touch and try on. Now, millions buy their designer labels online at Net-a-porter. Everyday, Net-a-porter ships out more than a thousand boxes of merchandise.

The key to net-a-porter’s success, was understanding what women desired. Net-a-porter is committed to innovations in web technology and has created a bespoke e-Commerce platform to offer its customers a fast, responsive and interactive user experience. With its acclaimed editorial format, express worldwide shipping to 170 countries (including same day delivery to London and Manhattan), luxurious packaging and easy returns, NET-A-PORTER offers an unparalleled shopping experience.

They have also manage to differentiate themselves as an e-business with the whole idea of curating Net-a-porter such that it developed as a digitally delivered hybrid between a store and a magazine, a shoppable magazine in a nutshell. Net-a-porter also has its own fashion channel, Net-a-porter TV, on YouTube which features runway shows of top designers all over the world first hand, and interviews with all who are famed in the fashion industry. The site popularised the act of bringing fashion spreads in magazines to live by presenting them in a video format.




The failure of Napster
Napster is a peer-to-peer (P2P) file-sharing site that experienced troubles ever since its debut in 1999. The company allowed users to exchange music files without any kind of regulation, and without any allowances for royalties to be paid to the person who held copyright to the files. The popularity of this service at that time only contributed to its legal problems.

Although Napster did not directly violate the copyright of materials shared on its site, it did facilitate copyright violations. In 2000 Metallica filed suit against Napster for circulating a demo song the group had performed, before its official release. Shortly after that episode, Dr. Dre also filed a suit against Napster. When Napster refused to remove the songs from its service, it was the beginning of the end. Napster settled out of court in those suits. However, the Ninth Circuit Court shut them down before the settlement was made.

Essentially, it was due to Napster’s lack of regulations that copyrighted material had been exchanged illegally on its service. Napster also did not take appropriate action in a timely manner against the users who were pirating copyrighted material on is site. In the end, the Record Industry Association of America succeeded in getting an injunction against Napster and the company agreed to pay 26 million dollars to the injured parties, and filed for bankruptcy.



E-Marketing
I have also learned that there are many different marketing mediums available to be utilized online. Hence it can be quite tempting for entrepreneurs to flitter back and forth, while trying out each one in part. Many entrepreneurs also tend to switch quickly to a new strategy if they experience quick success with one. Unfortunately, by doing that, they are not able to fully realize the potential of each marketing method. Instead, whether or not a strategy reaps quick success, entrepreneurs dabbling in e-marketing should maintain one particular strategy and give it a chance to flourish. Trying multiple marketing methods while only investing limited input into each will only ensure partial benefits. Instead, entrepreneurs should focus on one or two marketing approaches, master them and make sure they have exhausted their capabilities before moving on or adding a new approach.
It is also extremely important for entrepreneurs to network with others in their business’s niche. Entrepreneurs can increase traffic to their own site by commenting or guest posting on related websites and blogs, as well as link to authorities in their niche for exposure and networking. Entrepreneurs should also perform a traditional SWAT analysis to figure out the website’s assets and flaws. Then, determine which opportunities are out there for their sites, and decide what external factors threaten them.

Security, Privacy and Legal Issues
Security over the Internet is of immense importance to promote e-commerce. Companies that keep sensitive information on their websites must ensure that they have adequate security measures to safeguard their websites from any unauthorised intrusion. A company could face security threats externally as well as internally. Externally, the company could face problems from hackers, viruses and Trojan horses. Internally, the company must ensure security against its technical staff and employees.

Security can be maintained by using various security tools such as encryption, firewalls, access codes / passwords, virus scans and biometrics. For example, a company could restrict access to the contents on its website only through the use of a password or login code. Similarly confidential information on websites could be safeguarded using firewalls that would prevent any form of external intrusion. Apart from adequate security measures, appropriate legal documentation would also be needed. For example, a company could have an adequate security policy that would bind all the people working in and with the company.

Moreover, a company could also be held liable for inadequate security procedures on its website. For example, last year, a person decided to sue Nike because the Nike’s website was hacked and the contents of the domain were re-directed through the person’s web servers in the U.K., bogging them down and costing the web hosting company time and money.

Staying Connected


 
-->
Human beings are by and large social beings. Many people feel an implicit need to stay connected with people around them, expand their networks and also share what they know and what they are thinking about. Therefore, it comes as no surpise that social networks have always been and will always be a very important part of people’s lives.

Furthermore, it is commonly known that no man is an island. People depend on each other for both tangible and intangible help and benefits all the time. Most of the time, people may obtain opportunities not just based on what they know, but also who they know. Though social networking has existed since the medieval times, bringing social network online definitely has its benefits over social networking in real life.


-->
Perhaps the most apparent difference between social networking in reality and social networking online is whether each person’s network is visible. In real life, it is difficult to find out how your contacts can offer you opportunities. However, when it comes to social networking online, people are able to view the extended network of each of their contacts in order to turn their network into a useful route to get to your next destination, whether it is getting a new job, finding a new partner or place to live.

Besides, social networking sites online have greatly expanded people’s reach. They made it easier than ever for people to find old friends and make new ones. These days it is commonplace for people to form networks even in places they have never been to. People are able to stay connected with friends from halfway around the world. With such new networks come new opportunities.


-->
Social networking sites are redesigning their approaches to networking in very intelligent ways. Social networking operates on many different levels, with family members, close friends, acquaintances and work colleagues. Such separate social circles consist of different people that may know different aspects of the person. People always have lots to share, but they would not want to share everything with everyone. Therefore I find it very smart of Google+ to come up with the feature of segregating friends into different circles. This makes it really easy to share information with one group, while keeping it from others. It also allows the user to cut out the noise by choosing whose updates to read.



Another feature, which really caught my attention, is Hangout on Google+. It really brings back the beauty of being able to hang around your friends and chat with each other, without having to follow a strict schedule. With Hangout, other members of the same group can also drop in at any time, just like bumping into friends at a local cafe. This solves the problem of busy schedules, complicated planning and removes any kind of barriers, which keep friends from staying close to one another.

These features make things a lot more convenient in terms of categorizing content to be shared by users and they mimic real life interaction in the most natural way. So far, no other social networking site, including the most popular Facebook, is able to provide users with a similar experience. At the moment, Google+ is still lagging far behind in terms of usership. However, this lack of popularity could be due to a lack of awareness and people’s apprehension in shifting away from the largely popular Facebook. However, with the right exposure, I believe that with Google+’s potential in terms of operation, it may soon surpass Facebook.

Web evolution - from 1.0 to 3.0


Internet standards have changed drastically over the past few decades, progressing from the buzzwords commonly known as web 1.0 to 2.0 to 3.0. 



The web started off very basic in its approach in web 1.0, (being considered the “read-only web” by creator Tim Berners-Lee) it only allowed users to search for information to view, without any interaction involved. Web 1.0 includes applications like the shopping cart involved in e-commerce, which was popularized in the 90s.

The web gradually progressed to being focused in the Folksonomy (a term coined by Thomas Vander Wal) concept in web 2.0, which is a classification system based on collaborative methods and practices to tag content. These practices include social bookmarking, social classification, photograph annotation (as seen in Flickr), social indexing and social tagging.

More simply, Web 2.0 provides a platform for information sharing, interoperability, user-centered design, and collaboration on the World Wide Web, allowing users to also collectively classify and find information on others.

Most importantly, the 2.0 software puts power in the hands of users and allows them to interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community. This is in great contrast to websites using web 1.0 technology, where users are limited to the passive consumption of content that was created for them. Web 2.0 does that by using read-write web technology, which application can be seen in social networking sites such as Facebook and Twitter, blogs such as Blogger and Wordpress, wikis, and video sharing sites such as YouTube.




Further down the evolutionary road, web 3.0 is what many web experts now discuss. Web 3.0 combines semantic markup, (which is publishable and reusable structured data records) and web services, promising the potential for applications that have the ability to communicate with each other directly, and for broader searches for information through simpler interfaces.
The Semantic Web requires the use of a declarative ontological language like OWL to produce domain-specific ontologies, which machines are able to utilise to reason information and come to new conclusions, instead of simply match keywords.

Web 3.0 also features the latest trends for personalisation and artificial intelligence. Personalization technology enables the dynamic addition, customization and suggestion of content in whichever format relevant to the individual user, based on the user’s implicit behaviour and preferences, and explicit details which can be accessed via social media sites and other applications the consumer uses which require the input of personal information. The early application of this technology can be seen in Google’s targeted advertising. Whereby advertisements only appear on someone’s page based on the history of the users’ Internet browsing patterns by picking up keywords users’ search overtime.

When it comes to the discussion of the artificial intelligence aspect of web 3.0, futurist John Smart, lead author of the Metaverse Roadmap, defines Web 3.0 as the first-generation Metaverse, which he explains as the convergence of the virtual and physical world. In this sense, a web development layer that includes TV-quality open video, 3D simulations, augmented reality, human-constructed semantic standards, and pervasive broadband, wireless, and sensors is created. Web 3.0's early geosocial (i.e. Foursquare) and augmented reality (ie. Layar) webs are an extension of Web 2.0's participatory technologies and social networks (Facebook, etc.) into 3D space.

 
However, the Semantic Web is still in a development phase and researchers are still in the process of defining the most usable design models. This process requires the participation of thousands of web experts over time to produce such domain-specific ontologies necessary for its functioning. On the other hand, there are web applications that are pushing current boundaries with search integration and social graphs such as Google+. With promises to enhance search and bring consumers’ entire online “life” to their fingertips by integrating emails, notifications, webstats and more into the same account, Google+ makes the vision of Web 3.0 seem that much closer.

The Internet, a new beginnning for mankind





Being born in 1991, I have never really experienced life without the convenience of the internet. I chanced upon this documentary on Google over the weekend and was really compelled to share it due to how powerful the opening vignette was in proving that the Internet, or rather Google in this case, has changed the way people live their lives and even directly saved lives. It is somehow disappointing to witness that more facts can be found via Google than through consulting people we trust as experts.

However, by perceiving this phenomenon in another way, none of us can deny how powerful the Internet has become as an information seeking tool and how accessible it has transformed the whole world to become. With the internet, it is no longer difficult to communicate with people we care about halfway around the world. We can even have friends in a country we have never visited.

Google is really pivotal in helping the world make sense of an unimaginably large amount of information and it made knowledge limitless to anyone who has the desire to learn. As co-founder of Google, Sergey Brin said, "We are basically expanding people's brains with all the wells of information".

With the Internet and Google, now so much has become public. It is easy for people who do not know you, to learn many things about you. Who you are married to, where do you work, so on and so forth. In the past, private investigators used to be the only way to dig up information you need about someone. Now, it seems you could be your own private investigator. 


However, with convenience comes the lost of privacy. As the video above reveals, with Facebook's change in their terms of service two years ago, people's information would now be considered the property of Facebook, even after they remove themselves from the site. In this sense much of anyone's information is considered in the public domain and can be sold to advertisers at any point.



The Internet also completely changed the education system for the world. Now Institutes utilise e-learning systems like News in Class and show students animated videos in order to aid learning and liven up the learning process, like what Mr. Choy has been doing for us in Com 125 class.

Furthermore, the Internet altered what research means to me and millions of other students around the world, as explained by Jude Carroll in part 2 of the documentary. Research used to be about going to the library, sitting down with a huge stack of books and going through each and every one of them manually. Now, for a lot of students, research means Google. Students are able to read people's research off the web in the forms of e-journals on Google Scholar, Ebsco Host and many other scholarly sites. With this convenience of course comes the problem of plagarism. Ironically, professors now are all savvy enough to trace the source of plagiarised work via Google itself, or sit back and allow safe assign to do the work for them.



Among all the videos consumed in class this week, I found this the most helpful in my understanding of the Internet, its beginnings and its development. I used to think that the Internet and Web were interchangable terms for the same thing. I'm glad I can now tell them apart, and that I now realise the Web is a subset of the Internet. The Internet is basically a collection of computers connected to form a global networked environment, whereas the web is a system of interlinked hypertext documents contained on the Internet.

All in all, with the Internet comes extreme connectivity, which may bring us convenience and other immense advantages. However, the Internet may also take away the beauty of many traditional methods of communication such as handwritten letters and the excitement of receiving them in the mail. Thus, it important for all of us to progress with the world and exploit the Internet for its benefits while also combating its depersonalisation by retaining old school methods for when it is appropriate.
