Hi, everyone. Glad to be here with you to share some thoughts.
Catherine, in a few short sentences had laid out a series of fairly intractable and wide-ranging issues surrounding the impact of ICT which will take several books to address properly J. I will attempt to make some bite-size responses, which could well be long and incoherently bundled together, so please bear with me.
I think it is important to first tease out the main characteristics of using ICT for teaching and learning (T&L) at each ‘jump’ in their evolution. These can be simple-mindedly grouped to coincide with web 1.0, 2.0 and now 3.0 environments. As we know, web1.0 essentially allows for information exchange largely characterized by ‘one-way’ downloads of information with some basic interactivity (emails, etc) built in. Web2.0 brought out the social-networking nature of human society, throwing interactivity and the ability to collect, collate and summarized ideas/information into the mix through ICT. This builds a platform that mimics human interactions and is currently hugely successful. Web3.0 is gradually emerging as the tools themselves begin to learn about the users and hence be better able to provide what is deemed to be ‘needed’ to the user.
Yishay is right in pointing out the possible risks in using ICT, and I reckon we also need to be cognizant of what we are potentially losing while we gain from using ICT. In this vein, perhaps allow me to reframe Ross’s take in the following way when it comes to using ICT for T&L in each of the environments I mentioned above.
Under the web1.0, the use of ICT for T&L is primarily for efficiency purposes, where we use presentation tools (such as powerpoint) instead of transparencies. This way of using ICT does not impact the pedagogies very much, as it is still a relatively straightforward ‘replacement’ of T&L tools, and we ended up extolling the virtues of ICT assuming that it has ‘transformed’ learning. The early gains tended to be due to the greater engagement brought through the novelty effect, which faded gradually. In danger of sounding too dismissive, I have to add that truly transformational use of ICT, where the use of ICT is such that the T&L approaches would not be possible without the ICT (whether to good effect or not), has begun to emerge even during web 1.0 days. These are, however, limited by the scale of use, capability of ICT and the generally cautious attitude of educators towards ICT.
The web2.0 environment throws up every exciting possibilities, and yet has the overall effect of widening the engagement and learning approaches gaps between the formal (ie. classroom) and informal (social media etc) learning platforms. I think the disconnect between how students learn in the formal environment and how they interact & co-create/develop/generate knowledge in the informal space is something that educators are aware but haven’t quite make sufficient inroads into bridging. Perhaps we are too enamoured by our current educational structures such that we are not quite prepared to re-think and create a new, more flexible structure?
These enhanced interactivities can also bring with it potential dangers. Here are some that I can think of, and the associated challenges faced by educators.
(a) Being disconnected in a very connected world. While we can gain access to a whole host of info and expertise, there is a tendency to want to stick with groups who more or less share the same views (for a variety of reasons, including lack of time to explore beyond our comfort zones). This results in the individual knowing to a great depth the issues/ideas being discussed/shared within this group, but not necessarily sufficient breath or alternative views. My favourite example is to compare the outlooks of the New York Times readers with those who exclusively follow Fox News. The challenge to educator in this context is to design and expose the learners to a good balance of perspectives.
(b) ‘Loss’ of control of learning outcomes. A corollary to (a) is that educators will no longer have good control of the learning outcomes within the formal environment given that the learners are very connected within the informal environments. Imagine teaching the Darwin’s theory of evolution in the classroom, while the students are exposed to political, artistic and religious interpretations outside the classroom. The learning outcomes can be quite unpredictable, and it is a challenge to the educator to equip students with the tools and the open-mindedness to discern issues etc for themselves, ie. 21st Century skills, more or less.
(c) Losing our cognitive abilities to think deeply? We are essentially browsing, and not really ‘reading’ these days. As such, we become good at evaluating and synthesizing info/knowledge into convenient small-size packages for mutual consumption, which is a good thing. What is not too great is that we increasingly lack the patience and the mental ability to navigate through a complex argument that necessarily requires a lengthy discourse. We simply want such arguments to be put down in bullet point form for easy consumption. This can result in us being increasing good at collating information/ideas and repeating the collated results to each other without sufficient critical analysis. If so, original ideas could be few and far between while not denying that innovative variations of the same ideas can proliferate. Group-think can easily become the norm. This is potentially a very serious issue, as such reflective thinking would need the right set of circumstances to develop, and my take is that being able to read ‘deeply’ is a crucial aspect. The challenge to the educator is to scaffold the T&L interactions such as to encompass a good range of learning engagements.
Thus, while I am really excited by web2.0 environments and the learning potentials it can bring, I am also concern about the effects of such environments, and that if our educational approaches do not take such changes sufficiently into account and evolve/adapt a new set of responses to T&L, we can be in for a really rough ride. Unlike the early introduction of technologies, such as radio & TV, the interactivity made possible by ICT is such that the educators cannot afford to carry on with business as usual.
The web3.0 environment brings more exciting and also potential dangers. I am excited about the possibilities that the tools we use for learning can learn about the learner, and thus able to make explicit the thinking/learning process to both the learner and the teacher. For the learner, this can be most helpful in identifying learning blind spots, misconceptions and so on. For the teacher, it becomes a powerful tool to help design appropriate intervention to enhance the learning experience of the student. This will be one major step towards personalized learning. As for potential danger, I would just speculate that the biggest could be a compromise to our ability to think as such web 3.0 tools start to take over cognitive functions. I recall an experiment by a Dutch research team which found that the group of experimental subjects being given the most help in solving puzzles turn out to be less able to develop strategies to solve the puzzle and became stagnant in their progress; compared to the group with little help, which while performing badly at the start, gradually evolved to become better and surpass the group with help.
Sorry that this turns out to be a long-winded essay. I will comment on the economic links later
