Summary of Learning

Thank you to everyone for the fantastic experience in EC&I 833.  It has been a privilege to share ideas and thoughts with everyone.


My journey through school with colour-blindness

I’m colour-blind. Although this is a minor disability, it has affected me quite often throughout my childhood and even today as an adult.  One can take for granted the use of colours in the world we live.  Here are a few examples that can lead to frustration for colour-blind people on a daily basis:

  • Traffic lights
  • Colour coded systems in books and activities
  • Using colours to divide teams in sports
  • Using colours in art (I hated when teachers asked me to colour my art as I didn’t have the ability to pick proper colour combinations and always had people commenting on how bizarre it was that I chose certain colours.)
  • Choosing clothes to wear every morning (I’ve received many comments on my “interesting colour combinations”)
  • Cooking food (Make sure to check the colour of the meat for doneness)
  • Measuring pH as a science teacher using colour pH strips
  • Identifying minerals and rocks when teaching Earth Science 30.
  • Using colour codes when working on electronics (resistor codes are based on colours)
  • Fixing my car/home wiring
  • Making puzzles
  • Describing and object and being asked what colour it is.
  • Purchasing furniture or objects where colours is key.
  • Painting walls.
  • Cleaning certain things.
  • Constantly being asked what colour things are because people know you’re colour-bling. (Nothing is more stressful and anxiety inducing.)

As one can attest, we use colour every day in hundreds of ways.  Experienced colour-blind people are almost totally unnoticeable in society due to learning tricks and using certain technologies to adapt and make sure their disability doesn’t become an inability to function.  In this post, I’ll be sharing a few of my experiences with my disability and how I’ve used this experience to help some of my students who are also colour-blind in my classroom and school.  Some of these technologies are very simple and, in many cases obvious, but we must be careful not to ignore simple solutions in terms of accessibility.  Solutions and tools can be everywhere, and we must keep our mind open to new solutions that aren’t necessarily high-tech software and hardware solutions.

Situation #1

Colour coded activities and learning resources. Many teachers use colour codes when teaching grammar and writing structure.  Colours can also be used separate students in groups, mark sections in an assignment or even be used as a formative assessment tool.  Imagine a student knowing certain answers but having to result in guessing the right colour as they cannot distinguish the right answer. An excellent example of how to go about solving this problem is the use of shapes and symbols in conjunction with colour.  Providing an alternative makes the activity more inclusive to all students.  An excellent example of this method what presented by the team of Mélanie, Sage, Sonja and Justin during their presentation on assessment technologies.  Using Kahoot, they posed a question to the group and displayed on the screen were colour coded answers linked to a chart of results that was also colour coded.  Linked with each colour was a shape which I really appreciated as it allowed me to confirm the link between my answer and the displayed result.  This was a great example of using an assistive technology in a simple yet effective manner.

Situation #2

Traffic lights. Traffic lights are built in such a way that the coloured lights are always in the same order.  When the lights are vertical, red is always at the top, yellow is always in the middle and green is always at the bottom.  When traffic lights are in a horizontal configuration, the red light is always on the left, the yellow light is in the middle and the green light is on the right. Of course, this situation doesn’t present itself often in the classroom, but I’ve met many teachers who use traffic light images or traffic light analogies as tools to teach certain concepts in the classroom.  On occasion, I’ve seen handmade posters of traffic lights on classroom walls that were incorrect to the standard.  Although this is a small detail in the eyes of a person who is not colour-blind, it can be a large source of stress and frustration for a student who suffers from colour-blindness.  Imaging how a student feels when he or she knows how to answer but simply cannot get it right due to not being able to pick the right colour.  By observing the standards of traffic lights and being consistent, the traffic light analogy can still be used in the classroom by everyone, as longs as the colour-blind students know of the standard and it is applied properly.



Situation #3

Cooking class. Nothing is more frustration than trying to cook a steak for guests on a beautiful summer day and trying to see if a steak is rare (red), medium (pink) or well done (grayish?).  This is only one example where colour is used in the world of cooking. I’ve had students express their frustration while attending cooking class as they felt like they would never be able to gain the skills required to excel in the kitchen.  Let’s also underline the safety factor in consuming unproperly prepared foods.

In this situation, science and technology come to the rescue as assistive technologies.  Thermometers (especially electronic thermometers) are becoming the tool of choice in judging the doneness of meats and many other food items.  Over the past few years, their low cost and their ubiquitous availability has made their use almost universal in most home and commercial kitchens.  Most renowned chefs now encourage people to abandon the use of colour in judging food preparation in favour of thermometers as they are more accurate and increase the safety factor in cooking.  In addition to thermometers, using mass/temperature/time charts can also be used to help all students. The kitchen in my school uses electronic scales on a daily basis to measure the mass of certain ingredients which allows students to determine the temperature and the time needed to cook things by using a variety of standard charts.





Once again, these are not high-tech solutions in the world of assistive technologies but are another example of technologies that can help everyone and make the world a better and more inclusive place.

Situation #4

Teaching electronics and learning resistor colour codes.  The Saskatchewan Grade 9 curriculum has a unit on electricity and in this unit, colours are often used to distinguish parts of a circuit and in certain situations electronic components such as resistors.  As resistors can be quite small, writing their values on the component itself would not work, as a result, colour codes are used as a way to identify their resistance value.  Students and teachers who are colour-bling are at a big disadvantage.  In my amateur radio class, we were even requited to memorise resistor colour code despite the fact that I could never use this concept in the real world.  To overcome this situation, I purchased very inexpensive digital multimeters, around 10$ each, as a way for students to measure the actual value of the component without having to guess using colour codes.



This technology has an additional benefit that it allows us to more completely and thoroughly analyse circuits using actual numerical data which removes ambiguity for everyone involved.  In addition, the kids love using electronic test equipment!  In the past few years, inexpensive component analyzers have become available through internet resellers directly from China. These fantastic little tools allow students to test electronic components within seconds and verify their type and their values.  Once again, technology provides a level playing field for those who don’t have perfect colour vision.

I remember being in elementary school as a colour-blind student and having large amounts of stress associated with art projects. I guarded my coloured pencil crayons with vigilance as the shared crayons provided by the teacher often didn’t have the name of the colour on the pencil.  Some students sharpened the pencils from the end where the colour was identified and with wax crayons, the paper wrappers that had the name of the colour was often removed and lost.  I cannot convey the stress associated with trying to find a colour and not knowing if it even was available in front of me due to unavailable labeling.

Assistive technologies are fantastic, and many people rely on them with many people not even noticing their importance.  I urge every teacher to keep in mind my experiences when considering activities and tools for learning.  I acknowledge that many students have much more severe needs than the examples I have provided related to colour-blindness, but we must not ignore mild and light needs related to assistive technologies.  For the well-being of everyone we must remain attentive to the needs of all students and recognise that adaptive technologies can assist students that don’t need them and provide and richer learning experience in each case.

Education 3.0 – I’m not a futurist, but I’ll take a shot

In application programming, upgrading versions to a “x.0’ step is a giant leap in functionality and features.  Accompanied with this technological leap in software are often many bugs and problems that make transition to new promise-filled software difficult and at times purely frustrating.  Over time, these bugs and problems come to pass through new releases of software in x.1, x.2 and x.3 releases.  Personally, I always dread x.0 releases and often wait for x.1 and x.2 releases before updating software on any of my computers, phones or tablets.

Fortunately (or unfortunately, depending on your perspective), the paradigm shift that took us from Web 1.0 to Web 2.0 was not as drastic as in the software world.  As we were prompted by the presentation team of Jana, Katie, Brooke and Kyla O., to recall our personal experience of the shift between Web 1.0 and Web 2.0, I had a difficult time identifying any drastic transitions that changed the way I used the internet.  My experience was so gradual over time that the paradigm shift was not evident in my experience.  Perhaps due to living in rural Saskatchewan with internet access over a 28,8 Kbps modem and eventually a 56kbps modem, my experience with the web was very limited and lagged by many years those whom lived in more urban areas of the province. Although not software related, the big shift I remember as a child at the time of the transition between the Web 1.0 and the Web 2.0 was the arrival of broadband internet in my community. Having a 1.5 Mbps always-on ADSL line changed the way I was able to use the internet.  My life changed from using the internet with specific tasks in mind and maximizing my time online as to be as efficient as possible to “Browsing” the internet in my free time and exploring every nook and cranny the web had to offer without worrying about tying up the phone line in the house.  The internet became a utility as opposed to an occasionally used service.

The world of education has also witness large shifts much like the web and I would argue that as the internet shifted from web 1.0 to web 2.0, the world of education also changed forever.  As the new “social” web evolved as mentioned by Daniel Nations, so did the relationship students and teachers also had with technology and the internet.  The internet was initially used as source of information that tried to emulate libraries and did fairly well to a certain extent, however, once the internet became interactive, it transformed into a versatile tool where the possibilities are endless.  From enabling effective communications to opening new windows into the realities of the world, students have never had so much power and control over their education. As it is said: “With great power comes great responsibility.”  Our students have grown up as digital citizens and have been thrust into the world of the social internet without necessarily having the tools to cope and navigate this vast world.  As a result, our jobs as teachers has transitioned from being transmitters of information and knowledge to being stewards and guides in deciphering the firehose of information that is constantly entering the minds of our students through social and traditional internet media.

What is the future of education?  What will education 3.0 look like?  While teachers in Saskatchewan contemplate exactly these questions through the reimagine education campaign, we are evolving our methods of teaching by keeping in mind the relatively “new” approaches related to learning theories like constructivism and connectivism.  To me, the future still looks a bit fuzzy.  I’m certain that technology and the internet will play an increasing role related to how we as teachers accomplish our mandate.  My initial thoughts lead me to believe that like Tim Berners-Lee eloquently agues in his TED talk about the future of the web, we will be in a world of linked data.  Companies like Google, Amazon and Facebook are gathering such vast amounts of data that interpreting and using that data can become extremely complex.  Finding links in data is the future of how we will use the internet and make new discoveries. I believe we as teachers will become facilitators for helping our student acquire knowledge by assisting them in making these links in data that will be freely available with technology.

An excellent example of how we need to help our kids think is presented in the following podcast by Adam Sage where Joe DiRisi goes through his scientific discoveries and how they are all done by finding links in data.  Enjoy this one, it’s an awesome episode!
