More Cowbell: Signal-to-noise

Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. Wikipedia

This is a scientific term that relates to how much background noise there is interfering with the data or information you are trying to receive. A simple way to think about this is having a conversation in a party. If the noise of the party is too loud, you can’t pick up the signal (what the other person is saying). There is a point at which the noise does not interfere and the signal/communication is easy to hear, then moving along the scale the noise can interfere a little or a lot.

With machines this ratio is easy to calculate. With humans it’s a lot harder. It isn’t always about the quality of the signal, it’s also about the the willingness of the receiver to receive the signal. Sometimes people are not ready to receive the signal no matter how clear it is. Sometimes people choose to listen to the noise. Sometimes the noise is in their own head, not just coming from outside.

We are currently living in a world where a large number of people pay attention to the noise and are missing the signal altogether. A world where the noise is intentionally being spread. A world where the signal is considered noise. But humans aren’t machines, and so the noise isn’t easily calibrated and removed.

Social media used to amplify the signal, now it amplifies the noise. News used to amplify the signal, now it constantly reports about the problem of the noise, thus highlighting the noise and bringing it to everyone’s attention… not always in a negative light… or putting the signal and the noise on an equal footing as if to say here are two equal signals to be weighed and considered. As a result, communities, families, and friendships are being torn apart as they argue about what is signal and what is noise.

I’m reminded of the ‘More Cowbell’ skit on Saturday Night Live.

The noise is becoming too loud to receive the signal in any meaningful way. We need to simultaneously turn up the signal and turn down the noise. If not, we better get used to the cow bell.

If at first you don’t succeed

As the saying goes:

“If at first you don’t succeed… try, try again!”

Working with students, what you sometimes see is:

“If at first you don’t succeed… quit before someone sees you fail.” Or, “If at first you don’t succeed… avoid trying altogether.”

What the saying should say:

“If at first you don’t succeed… try, something different.” (Try a different approach, don’t just try the same thing over again in the same way.)

When things aren’t working, students seem to have two main gears: keep moving forward, because curiosity points to getting unstuck. Or ‘Park’ because it’s not worth the effort or embarrassment.

Teaching students that effort matters more than results or that a failing result can still be a learning opportunity, is to teach them to be resilient and to persevere. This doesn’t mean everyone gets a participation badge, this isn’t just about another quote, “If you did your best, that’s all that really matters.”

No, this is about creating an environment where students aren’t afraid to bite off more than they can chew… to be so ambitious about their goals that a failure to achieve them still puts students much farther than if they had set the bar too low and succeeded.

This is about creating opportunities for students to do something epic, rather than just something every other kid is doing, with a sample you share of the expected result… a cookie cutter task where students produce the same round cookies, but get to decide where the pretty sprinkles go to make their cookie look a little different than everyone else’s.

If you want students to really succeed, well then they have to start a task with the real potential for failure. They have to struggle with uncertainty of success. They have to learn that not reaching a perfectly successful goal can be an opportunity to learn more and different things. Because without authentic struggle, learning is shallow and fleeting.

“If at first you do succeed… the task probably wasn’t hard enough to truly learn something new.”

Like it was yesterday

April 5, 2007

Yesterday, I was in a meeting with a parent and one of my students, (why do teachers have parent meetings about a teenage student’s education and not have the student there too?)

The parent observantly noted that although her son could be physically in a room, he could often ‘disconnect’ and be elsewhere in his mind. For him to be more successful, he would need to engage more in what was going on. I told him, with all honesty, that I too had that problem to the point that my parents worried that I might have been on drugs (I wasn’t). It took until my Grade 13 year (Ontario, Canada) to recognize that I needed to be a participant in the classroom in order to ‘stay connected’.

As I was talking my student interrupted and said, “I just had a flash of insight, I’m a mop not a sponge!”

He got it! And today he proved it. He was a fully engaged participant in my Math lesson. I can hear myself in upcoming classes, “Remember to be the mop”.

———–

That was from my Pair-a-Dimes blog post, “I’m a mop not a sponge”: Metaphors all the way down. Last night I found out that this young man passed away unexpectedly. It’s so sad to hear news like this about a former student. I immediately remembered this incident, this moment in time when I saw a light bulb light up in a young kid’s mind.

This was my last year as a Grade 8 teacher. There are other memories of this student, but they are more distant, faded… it was over 14 years ago. However this memory, I remember like it was yesterday.

Future Tech: Prescription Glasses Metaphor

It’s the early 2030’s and you are walking downtown, heading to a specialist appointment. You don’t know where the office is, but you aren’t looking at a map on your phone. You haven’t done that in a few years. No, instead, you are looking through a contact lens that is like a heads-up display giving you augmented reality directions. There is simultaneously an arrow flashing 3 times in your view, showing you that you need to turn right in 15 meters, and a haptic vibration from an implant in your right elbow. The vibration you feel in your elbow has a pattern of long-short-short, which you have set to let you know is a map direction.

Had the vibration been in both elbows with a short-short pause short-short vibration, then you would know that it was a phone call from one of your chosen favourites, and your heads-up display would have shown you the name and/or photo. You have it set so that you need to look down and right to see the name and face of the person calling, but it could have been set to come up right into your line of sight. If the call was from an unknown number, you would not even have been bothered. Instead the call would have been answered by an Artificial Intelligence (AI) assistant that (for voice phone calls) sounds like you, but with a decision tree to decide if the call is worth bugging you, leaving you a message for later, or even blocking the call if it determines it is spam. Since you are just walking, it might have offered you a text version of the message on an augmented display, but if you were in the specialist’s office, the AI would have waited until your appointment was over to notify you of a message.

You arrive at the specialist’s office and because you connected on LinkedIn, your AI has identified the secretary from her profile picture, and her name pops up above her head so that you can greet her appropriately. You wave your hand over a scanner, stare briefly at a ‘Yes’ box to indicate that you want to share your personal medical information, and you are done signing in. Because this is a medical specialist, that data includes the last year’s worth of bio information like heart rate, blood-sugar levels, and even blood pressure. A small implant collects this data in a just slightly more sophisticated way than the current apple watch. If the doctor didn’t want to run some specific tests on you, all this would have been done remotely, with the Zoom call actually happening through your contact  lenses and an implant in your ear. To get around the fact that you don’t have a camera on your face, the person you are talking to sees a perfect rendition of your face, and even if you were watching, you wouldn’t know that is wasn’t actually you. It even uses your voice intonation to help determine the emphasis on facial expressions, so if you said the same thing twice, it would look subtly different, rather than robotic.

Is this a future you want? Because it’s coming… and you will embrace it. You will participate in it. Because to not do so, would be to have a disadvantage.

When my youngest daughter was 9, we took a trip to England and France. In Paris we went to the Eiffel Tower, and it was there that we learned our daughter needed glasses. We had just come back from China, where we had been living for 2 years, and we hadn’t had eye exams in almost 3 years. We got to the top of the tower and my wife started pointing out things to look at, and my daughter couldn’t see any of them. At 9, she didn’t know that she couldn’t see well. She thought everyone saw the way she did. Distant hills were supposed to be blurry. What about street and store signs? Who needed to see those, they were in Chinese anyway, and we couldn’t read them. Once we returned home, we went to the optometrist and our daughter has worn glasses or contacts ever since.

The future I shared above is a future with a metaphorical 30/20 vision. It is the ability to see and feel things that people today can not see or feel without augmentation… and this will be the new version of 20/20 vision. The same way that my daughter was disadvantaged without her glasses, any person not augmenting their lives with technology will be disadvantaged compared to those around them. They will be less connected, less informed, less able to see. It would be like my daughter realizing that she couldn’t see like everyone else, and still deciding not to get glasses. Augmented reality will be the prescription glasses of the future, and you can choose to use the prescription, or stay in the dark.

Smooth rocks and glass

“Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: what is soft is strong.”

― Lao Tzu

This seems to be a time of strong dichotomies, where people hold to their principles and biases. The response to opposing sides runs along two lines, harsh or sarcastic. I would argue that sarcasm is just another form of harsh. In both cases, there is no attempt to win over the other side, merely to call it stupid, or to make fun of it. Neither is an attempt to convince because it is believed that it is too late, that people are too set in their ways.

But compassion, though appearing to be soft, is strong. Authentically caring may seem yielding, but it is strong. “Be like water“. This is not a time to win points, to be louder, to be right in such a way that you only want to prove someone else to be wrong. It is a time to be soft, caring, and kind. To show genuine concern for others. This will not work for everyone, but it will be far more effective than being harsh or sarcastic.

The tides will ebb and flow, and the sharp edges of rocks and glass will slowly be rounded.

Mindfulness is witnessing the dance

“Life is a dance. Mindfulness is witnessing that dance.” ~ Amit Ray

Today’s meditation was about meditation as a means to become a witness, and thus using meditation as a way to disconnect and observe rather than experience.

While I understand that meditation can be used to do this in a positive way, I wonder how many people bare witness to their own lives without actually living, not feeling anything? Kids cutting themselves because that’s when the feel the most; zombies moving through life from sleep to work to alcohol and/or television before sleeping again; people bitter about the hand life dealt them, who live in disappointment, numb to everything around them; lonely people, who may or may not actually be alone.

I think too many people are already witnesses to their own lives. I’m not saying meditation isn’t a good way to do this, but I wonder how many people need to do the reverse? I know that there are times in my own life where I’ve felt like I was existing rather than living, the observer rather than participant, but family and friends are good at snapping me out of this.

The unexamined life may not be worth living, but there can also be paralysis by analysis. You can watch a surfer and see all their moves, you can know everything about the wave, it’s energy and flow, but if it’s you on the surfboard, it’s probably best to be enjoying the ride than trying to witness it.

Happy surfing!

Sharing again

Revisiting my uncle, I was reminded of this story, and my post, forgotten dream:

From my earliest memories I can remember our house containing numerous bookshelves with books double stacked, one in front of the other, with whole sections having books stacked horizontally, so that 6 or 8 horizontal books could take the place of 4 or 5 vertical books.

And I read almost none of them.

The dream was a dream of lost opportunity. Of being blind to the ocean of information that sat before me metaphorically unseen, and literally unread.

Adding to this we need to spend quality time with people we care about… and not take them for granted. It’s easy to think the people closest to us will always be there and forget to treat them the way they deserve to be treated.

Inversely it’s a good thing when we remove people from our lives if they are not worthy of our time. I love this quote by Isaiah Frizzelle about creating boundaries for people that don’t deserve access to your life, “Time does not allow reentry and an apology does not always allow access.”

To the fish, water is invisible. It’s fine for us to ignore the oxygen around us, but we need to pay attention to, and show love and respect to, the people we care about.

The cap gun

When I was a kid, I had a cap gun. It was a eight-shooter, with the caps coming in a ring that fit into the revolver cylinder. Put it in your cap gun and you could shoot off all 8 caps before putting a new ring in. But I never used it, I was always saving my caps. I hid them at my grandparents house, under the bathroom sink in the room my great grandfather used before he died.

This room was sort of my play room that I used at my grandparents, who lived on our street. It wasn’t a room used by anyone… except me. Fast forward to us moving to Canada when I was 9 (we grew up in Barbados). Our bags are packed and we are leaving the next morning. I remember the cap gun and about 30-40 ten-packs of caps. I gather them up and take them to my parents to pack.

“We can’t take that in the plane.”

So, after a little back-and-forth with my parents it becomes clear that the cap gun and hoard of caps is staying in Barbados. So I did what any kid would do… I spent the next 45 minutes to an hour shooting off every cap I had. I shot everything and everyone around me. I spent every last round, and then have the empty gun to my cousin.

It was fun, but not as much fun as using the gun all along, rather than saving every cap for this unforeseen occasion. While it was a moment to remember, it wasn’t memorable because I went on a shooting spree, it was memorable because it wasn’t as enjoyable as I had anticipated, and I realized that I missed out by hoarding caps rather than using them all along.

Today, I still laugh at myself when I catch myself doing something like this. A perfect example is when I get a sticker I like… I find myself not wanting ti use it. But I do. I remember the cap gun and all those unused caps and I peel that sticker and stick it somewhere… it doesn’t get ‘stuck’ in a drawer waiting to be never used.

What are your metaphorical caps, and why aren’t you enjoying them right now?

Standing wave

I remember hearing that on average human cells are replaced every 7-10 years. However, unlike the ship of Theseus not every cell is replaced. Some eye lens cells last a lifetime and there are other cells, such as some in our hearts, that can live for over 50 years. That said, at 53 most of the the cells that made me me when I was born have been replaced, some every couple days, some over years.

Last night coming home from Nanaimo, back to the mainland on the ferry across the Strait of Georgia, I was mesmerized by the standing wave made by the boat. I watched the wake of the boat out over the railing on an opening on the car deck, and stared at the water dancing across this wake. It occurred to me that despite the wake being consistently the same distance from the boat, as I stared at the wake, I was staring at a constant flow of water being replaced by water coming off of the front of the boat. The wave stays the same, but the water is constantly and completely changing.

Inversely, we tend to try to stay the same in an ever-changing world. We develop metaphorical standing waves that treat everything that comes our way the same. We develop patterns of behaviour where we react the same way to people and situations that come our way. Yes, we learn and we grow, but more slowly as we age. We tend to find comfortable, repeatable ways of facing life’s challenges in the same way. Some of us being more like small sail boats that confront every wave a little differently as our boat adjusts, and others more like a massive tanker ship, that keeps the same standing wave in all but the roughest of seas.

What standing waves do we create in our lives? What do we tend to leave in our wake? I’ve met selfish people that leave turmoil and chaos in their wake and go through life selfishly disrupting other people’s wakes, and I’ve met others that are selfless and worry more about helping others with their wakes than worrying about their own. The most dangerous of all are those that think the are the latter but are actually the former… they think they are what makes the seas calm while they themselves are hurricanes, unaware that they are in the calm of the eye of the storm they create, while those around them face the tumultuous winds and rough seas.

We should all think about the wake we create, and we would be advised to keep out of the wake of people who create disruptive waves. And while we slowly replace ourselves with our future selves, we need not create the same old standing waves if they don’t serve us well and move us in a direction we want to go.

Make Lemonade – A life lesson about perspective

This was my yearbook ‘message from the principal’ for Inquiry Hub this year:

_______________

Make Lemonade

          When the backdrop of your school year is a Global Pandemic, it’s hard to think of the things you got to do, and easy to think about all the things you didn’t get to do. It’s hard not to think this way when so much has been taken away from us. We are used to students mixing across grades and getting to know everyone in our community through events and potluck lunches. Well, this was not a year for those things. But when you look at the year we had, we were lucky compared to many high schools.

          We provided all-day schooling when other schools were having students only come to school for half a day and doing another course online, then switching these two around. Meanwhile we had our cohorts in school for the entire day. Other schools rushed students through quarters, with 2 courses at a time. We continued with our year-long classes. Courses in other schools were paired down to the essential curriculum. We had students continue to follow their passions and interests with Inquiries and IDS courses, and teachers continued to look at things in depth, and had time to follow student interests along the way.

          I was watching a TikTok recently and it was about things non-native English speakers didn’t understand when they first learned English, (I am definitely on grown up/teacher TikTok and have a different feed than a younger-than-me generation). The phrase that this person didn’t understand was “If life gives you lemons, make lemonade.” To most of us this is a phrase that means, when things are sour and going against you, make the most out of it. However, this woman was from a country and culture where lemons are used to spice things up, and the taste of a lemon is truly enjoyed. To her, “If life gives you lemons, make lemonade,” meant, appreciate the good things in life. She never understood the phrase to mean anything negative. When life gives you a wonderful lemon, well then celebrate and make some lemonade!

          When you look back on the past year, I hope you can see it from the perspective of this lady, and find the delicious lemons you made lemonade out of. Who did you spend more time with? What did you enjoy doing that you don’t usually do? What do you feel lucky that you had, that others didn’t have? If you were living in Toronto this year, you would have spent almost the entire year doing school from home, whether you wanted to or not.

          Also, we are heading into a summer with much less restrictions than last year. What are you looking forward to that you will enjoy even more than you ever have? What opportunities are you going to take advantage of, that you probably wouldn’t have? Where is your family going to travel next?

          It’s time to enjoy your summer… and make  some lemonade.
