Where are we heading with web semantics and who's at the helm?

I've just finished a slice of holiday reading involving "New technology trends in education: Seven years of forecasts and convergence" by Sergio Martin, Gabriel Diaz, Elio Sancristobal, Rosario Gil, Manuel Castro, Juan Peire and felt like reflecting on this. The group conducted a study on the the technologies most likely to impact education in the near future, by looking at technology metatrends from 2004 to 2014 - the report was based on the technologies highlighted in the NMC Horizon Reports.

The main trends highlighted were;
  • Social web 
  • Mobile and ubiquitous devices 
  • Augmented reality 
  • Semantic web 
  • Immersive environments 
  • Learning objects 
While most of the trends highlighted receive quite a bit of exposure I was interested in finding out a bit more about the Semantic web - from more reading I see it as a trend well worth watching I also I feel that we should not only focus on the technology but also the organisation of information to enhance learning. 

Overall I think this trend has eventuated naturally - as the web has grown there is a huge amount of data available on every subject imaginable - we now need to harness this information and create the best versions possible to use in education - the raw data needs to be made available so it can be used to create a better web experience and fulfil learners needs. As Tim Berners-Lee (inventor of the WWW who also coined the phrase 'semantic web') claims that this linked data will be how technology will advance the information revolution he began with the World Wide Web, changing everything 'from how users set up their online address books to how they pay their taxes' - people have started referring to this as web 3.0. Rather than listing information in tree structures, it will create a Web based on the relationships of people, places and things as they exist in the real world. When it comes to its application in education I can see that it would be extremely useful to filter out lots of the irrelevant information that students are faced with every time they open a web browser and create a more organic experience. Web semantics also relate to learning analytics where educational 'big data' is used to optimise learning and the way it occurs - from the subjects or courses that are available to the environment and method they are presented - Learning analytics become more meaningful and ubiquitous with semantic technologies. The khan academy has revolutionised learning by opening knowledge to anyone with an internet connection, and 'Knewton' has taken this a step further by using learning analytics to customise courses and methods for students. 

Although to me as a teacher this sounds absolutely amazing and could create the perfect curriculum for any student, I also consider that by allowing intelligent software to act on this descriptive information and follow logic paths based on it, the Semantic web could be reducing learning by making it too customisable and specific. Are we limiting our learning capabilities and the journey we are starting when we want to try something new - if the software becomes so advanced that it knows what we are looking for before we even think it (google now) will we be reducing creativity and exploration in students? Is learning about the journey you take or the destination? 

I am an avid user of gmail and google drive/apps for education and have ended up slowly (and reluctantly at first) allowing them to see all the data/documents/searches/web history on my computer/profile, although this has customised the web experience for me and the benefits of using google apps for education far outweigh the small worries I have about it - I am sometimes still occasionally anxious about the collection of data and is it somehow going to be manipulated and used as a revenue creator in education (or is this even happening already?) I also wonder who is leading the 'organisation' of data to create the Semantic web and is it for our benefit or theirs? In Eli Pariser's TED talk he highlights that the web is becoming a very personalised experience but are these 'filter bubbles' good for us and our own journey of discovery and learning? As an educator in New Zealand I also think about about our culture and if web semantics will take that into consideration, or will our web experience be overshadowed by a global culture that weakens community and cultural links rather than strengthens them. Plenty to think about until I get back to school next week!

How to collaborate with ChatGPT in the research process and actually learn something

If you have used chatGPT before, it can sometimes feel like talking with someone who has done too much of their 'research on Facebook', filling in gaps with random facts marginally related to the topic just so they can respond and keep the conversation going. However, if applied or 'prompted' correctly, with the user utterly aware of the limitations and ethical considerations, chatGPT can be a helpful research assistant. There is already a wide range of tools available that are built on chatGPT that can support many of the things described below; however, I am still a bit hesitant to rush in with most of them being 'freemium' or asking you to upload your own research and other details or data into their database, I'm happy to stick with the open version of chatGPT as it is what our students have access to. Image created with AI The following guide highlights some prompts, some follow-up questions and most importantly, what you need to do next to follow up a

Motivation and homework follow up...

Last week I wrote about setting a homework challenge to learn muscles of the body as an online game - the students then had to post screen grabs on google+ to show they had done it and to be in contention for the hallowed prize of 'King of the Muscles' and a cafe voucher. I wasn't quite sure how it was going to go, but by Thursday the buzz in all my senior classes was about ' poke-a-muscle '.  The boys were so excited about it they'd post a score, and then find out that someone had beaten them, and then rush out of the class at interval to get to a computer and beat the top score.  I even had an email on Saturday (two days after the due date) from two boys who had been practicing and spent the afternoon working together to try and beat the original high scores they had submitted with the homework!!!

Assessment beyond 2020

Where is external assessment going, and who are we thinking of when we are deciding the future of assessment beyond 2020.   This picture is the actual view I was confronted with, walking into our local community college gym, aged 16.  A place where we had played volleyball, netball and cricket was now being used to measure how much we knew about the things we had spent our school lives practically doing inside this hall, to see if I could pass GCSE PE.  It is now clearly ironic the amount of time that we spent actively exerting ourselves and demonstrating competency in the ‘doing’ of the skill was now going to be measured by writing down everything we knew about it in 2hrs to double check we knew what we were supposed to know.  The previous 24hrs before this vista had seen me cramming the information written on tiny ‘flash cards’ into my short term memory, even up to the walk down the corridor to find my seat I was memorising the diagrams I had drawn about things I don’t reme
