Averages and Parachute Packing

This is Part 2 of:

Average tells us nothing.

Here are some very well rounded marks of a hypothetical student in a course:

The student starts out very average with 60% on the first 3 tests:

On the next test, the student shows much greater comprehension:

Then on the final test, the student shows mastery of the PLO’s, the prescribed learning outcomes:

Now if these were tests on completely different units, unrelated to each other, you could argue that the student deserves a 70% final. However if the student was learning information that was cumulative and knowledge at the end of the course required understanding of previous work, then wouldn’t the student deserve a higher mark?

For example, if the student was learning to code, and the simple(r) concepts learned at the start of the course (that the first 3 tests were on) were required understanding to do well in the second part of the course: Shouldn’t the student’s final mark represent greater understanding of the course than the 70% final mark from the average of all 5 tests?

The Parachute Packing Analogy

I love the simplicity of this example! There are 3 students who are in a parachute packing class:

Students take 3 tests during the course.

Student A starts off strong and gets an A on the first test, gets a B on the second test, is over-confident, flounders and gets a C on their final test.

Student B is a solid B student and gets B’s on all 3 tests.

Student C struggles on the first test and gets a C, starts understanding the concepts and gets a B on the second test, then totally understands all the concepts and finishes with an A on the final test.

All 3 students have a ‘B’ average in the course.

Which student do you want to pack your parachute?

Average tells us nothing.

Part 1

It might be an exaggeration to say that it tells us nothing, but averages don’t usually give us enough information to be useful.

Individual student level: In Math class, kid gets an ‘A’ on his test on positive and negative integers. Then he gets a ‘C’ on fractions. Score averages to a ‘B’… but when the kid moves on to algebra, and most of the algebra includes solving problems with fractions, it’s unlikely the kid will do better than a ‘C’. The important information is the ‘C’ in fractions, not the ‘B’ average.

On a team level: When some team members have done amazing things and other tram members have done nothing new, measuring the average means absolutely nothing. You can’t look at averages when some team members will move and some won’t. The reality is that everybody has to be moving in the right direction, and when some are standing still, it doesn’t matter where the average is, it doesn’t matter if the average is moving slightly up.

The fact is that we are failing or we have failed if we don’t figure out where we are weakest and improve where we need it most. Athletes get this. They know that the weakest part of their performance is the area where there is the most room for improvement… this is a mindset we need on our teams to move forward.

Part 2: The Parachute Packing analogy and school grades.

When the street lights came on

How many of us Gen X kids stayed out until the street lights came on? That was the signal to head hone for bed. Until the street lights came on, all your parents knew about your location was that you were somewhere in the neighbourhood…. somewhere.

Kids today, their parents always know where they are. This isn’t that new. Even us X’ers didn’t let our kids have this freedom. We grew up in an era when news reports started telling us what a bad world we live in. Unsafe. Dangerous for kids.

Now we are locked down in a way that really limits kids freedoms even more. Where are you going? Who are you seeing? Are they all in your small bubble of friends? Coronavirus has locked us all down and limited where we go and who we see.

This is really tough for kids. They don’t have any equivalent experience of being out until the street lights turn on. They don’t have a place to be unsupervised by adults… not to raise hell and cause trouble, just to be kids.

How much of their time is organized. Even fun is organized… soccer practice, dance classes, music lessons, are all put in the calendar. Play is scheduled, like recess and lunch at school, every free moment isn’t really free at all.

I think we need to find ways to give kids some of the freedom we had as kids, when we could stay out, unsupervised, until the street lights came on.

Parenting and teaching

This morning I read a tweet from Bill Ferriter (@plugisin):


I have two awesome kids, both currently in university, that approached K-12 school very differently. One was an overachiever who always had to do well… ‘tell me what I need to do to get the best mark’. The other is also bright and wants to do well, but is happy to find her own path there. She’s more likely to put work off, but will be disappointed if she doesn’t do as good as she could.

They both did well in school, but they both had their own struggles as all students do. One such struggle they both had was math. Neither of them enjoyed doing math and we ended up getting tutors for both of them at different times.

It’s a massive shot to my ego getting a math tutor for my daughter in Grade 9 Math when that’s a subject I taught. But I couldn’t help her without tears and frustration. I was always showing it wrong. It took all the patience I had, and that wasn’t enough.

On the flip side, I know that it wasn’t always easy for our kids to be daughters of two educators. We deal with kids all day, and sometimes when we got home, we were kinda ‘done’. We knew every trick in the book, and they didn’t always get away with much that their friends could. I could share more on this, but want to respect the privacy of my kids.

Bill’s tweet, shared above, made me think of two things. First, it’s not always easy being a parent as well as a teacher, while not letting the teacher get in the way of parenting. Secondly, being a parent and watching your child struggle can make you a better teacher… it gives you perspective on how something that you as a teacher might think is simple, can become a huge challenge for a kid at home. It can make you question the value of homework, and it can remind you that kids have struggles that you don’t see at school.

Parenting is a humbling experience, and it can be an experience that makes you a better teacher.

Easy lies and the hard truth

This is a brilliant comic by Shencomix.com.

Lies are soft and squishy. They can be whatever shape you want. They are convenient. [They fit into any world view.] The Truth is hard and spiky. Hard to embrace. Worth embracing.

I’m absolutely amazed at how many (smart, educated) people are sucked into conspiracy theories and exaggerated (and clearly misrepresented) statistics that fit their world view… even when the theories are debunked.

Example : A US educator that I know shared this October 25, 2019 Joe Biden Tweet, which was a response to another tweet from a Washington Post article on pandemic preparedness:


This is the top reply which has been retweeted 71 times and liked 359 times at the time of me sharing this:


It’s absolutely ridiculous that someone with such influence can spread a conspiracy theory that the pandemic was planned. But it’s convenient. It fits her world view.

The problem is that is so much easier to cherry pick lies and convenient half-truths than it is to actually embrace and meaningfully interpret facts that don’t match biased opinions.

Sometimes lies are easy and the truth is hard… it’s spiky… But we want to live in a society where the hard truth is embraced, even if it isn’t something we want to hear.

Walk with a friend

Yesterday after work I went for a walk with a buddy. It was damp and a little cold out, but I overdressed and was comfortably warm with a couple layers open/unzipped. I’ve always been someone more comfortable warm than cold, and believe that there is no such thing as bad weather, just bad clothing for the weather.

One of the topics we discussed was that while on the outside everyone is coping and doing the best they can, the long game of dealing with Covid-19, which probably isn’t even half over, and the social effects of dealing with a pandemic are wearing people down. Pretending we are ok isn’t enough, when so many of us are struggling for such a long time.

I spoke to a firefighter recently and asked him what keeps him most busy at work right now. He said 3 things: Car accidents, overdoses, and suicides. Overdoses and suicides have gotten a lot worse since the pandemic started.

And we aren’t close to things getting better. Yesterday there were almost a half million (recorded) new cases of Covid.

I believe this was the worst one-day increase we’ve ever seen!

This is a depressing statistic that flies in the face of people who downplay the seriousness of the pandemic we are facing.

So things are not getting better, and people are struggling. What can we do?

First, take Vitamin D.

Next, check in with friends or family that might be really struggling. I saw this Facebook post from a friend today,

“Phone is always on, and coffee can easily be brewed. I’m doing a brother/sister check in. Especially this time of year. Showing support for one another…”

And one more thing I strongly suggest is getting outside with a friend. My walk yesterday was rejuvenating. My buddy and I talked openly and honestly about how we are doing, what we are struggling with, and what we just needed to vent about. But it didn’t feel like a rant. It was an opportunity to be honest about how we really feel right now. It was better than a phone call, although a phone call or video call can be good too. Meeting and doing something active was wonderful.

When I wrote “It’s just this” a few days ago I said,

We might have made these adjustments fairly quickly on the outside, but ‘this’ is still not normal, and so it’s draining, and requires more effort than usual. ‘This’ will take a bit more time to fully adjust to… We will get used to ‘this’ eventually, and when we do, we will find ways to thrive.

If we want to find ways to thrive, we need to first take care of ourselves. Go do something active with family or friends (within your bubble). Find reasons to be outside. Walk and talk. Connect with someone who you can be honest with about how you are really doing. Lean on those who can support you and let others lean on you if they need the same.

Red pill - Blue pill quote - David Truss

Red pill, blue pill

The Terms Red Pill and Blue Pill refer to a choice between revealing an unpleasant truth, represented by the red pill, or to remain in blissful ignorance, represented by the blue pill. These terms are in reference to the 1999 film The Matrix. ~ Wikipedia

We are living in a red pill/blue pill moment, except people are colour blind and everyone thinks they are taking the red pill.

Blog visits 2020 Daily Ink

By the numbers

I was catching up responding to some comments on my Daily Ink and ended up looking at my blog stats for the year. I seem to have a small, but consistent audience and so to those of you reading… thank you! As I looked at the stats, I notices a consistent pattern for days/months/year:

  • Almost 60% Canadian
  • Almost 30% American
  • 2-3% Australia, United Kingdom, then India and the Philippines (in this order)
  • Ireland and Malaysia at around 1% and it would seem visitors beyond that don’t come regularly.

I can name a couple people that keep my international stats up, (thanks Aaron in Australia and Manuel in the Philippines), and while I would have guessed that most of my readers would be from North America, I was surprised to see that stat at almost 90%. So, I went and looked at where my Twitter followers were from and found this nice map:

Twitter Map of Followers

It matches pretty closely with blog visitors other than a reversal of the US and Canada, and it makes sense that I have a local/Canadian following that would skew the stats in that way. And while I share my blog on LinkedIn and Facebook, it would seem that besides the Canadian slant, there is a good correlation between Twitter followers and blog readers.

It’s fun to look at these kinds of connections and to think about how easy it is now to self-publish and to share thoughts and ideas with the world… and while I’m mostly sharing my thoughts and ideas with North Americans, it seems that even a small daily blog can get around a bit.

Again, thanks for following along!

It’s just this

I was speaking to a colleague at work about sleep. She said that she was getting to bed really early and passing out exhausted, and I was saying how I was staying up late not able to fall asleep, even though I feel tired. She pointed both hands up, palms open, and made small circles, “It’s just this“.

I totally understood.

‘This’ is wearing a mask most of the day, and not seeing full expressions on the faces of students and colleagues.’This’ is pausing outside doorways to give people a wide birth to pass.’This’ is being busy, but that busyness not feeling as rewarding.’This’ is not all sitting around the same tables at lunch.’This’ is sanitizing your hands because you touched a door knob.’This’ is limiting students’ plans when we are used to always getting to yes. ‘This’ is knowing that we will likely start next September much the same as we started this school year, and knowing there are still 8 months of ‘this’ to go this school year. ‘This’ is living through a pandemic.

We might have made these adjustments fairly quickly on the outside, but ‘this’ is still not normal, and so it’s draining, and requires more effort than usual. ‘This’ will take a bit more time to fully adjust to. More time, and more sleep… Sweet dreams. We will get used to ‘this’ eventually, and when we do, we will find ways to thrive.

Resilience Revisited

Right now it seems like I chose the right #OneWord for 2020: Resilience. But as you read my last post of 2019, written before we learned about the impending pandemic, remember something… We are social beings and we are not incredibly resilient on our own. We need a community, we need friendship and love, we need each other.

Relationships, be they with family, friends, co-workers, student/teacher, and even pets, build our resilience, and our ability to not just cope, but to thrive.

Let’s support one another and show our resilience together!

Here is the post:

December 31, 2019

If I were to pick 2 words for 2020, I might pick “Growth Mindset”, but if I’m only choosing a single word, it would be:

Resilience

The world needs this word right now. Here are some specific places I see a need to pay attention to this #OneWord in 2020.

In Schools:

Student anxiety seems to be on the rise, and anxiety lowers resilience and the willingness to try new things. Words seem to ‘injure’ students in ways that victimize them rather than make them stronger. This is not to say that students should tolerate bullying or inappropriate language or slander, rather they should speak up, defend themselves, and report poor behaviour. Instead it seems that they feel wounded and do not act. This is a sensitive topic, but one where I’ve seen a greater awareness of adults who want to support students and at the same time I see students allowing words to hurt them deeply, giving too much power to the transgressor.

In Politics:

I said this in Ideas on a Spectrum, “In a civil society, dialogue is the one problem-solving strategy that should be sacred. To do this, free speech is essential. But right now there is a culture of ‘attack the opposition’ that is very scary.“ – We need to be resilient when hearing opposing views, and understand that, “…we must be tolerant and accepting of opposing views, unaccepting of hateful and hurtful acts, and smart enough to understand the difference.” When we can’t have conversations with people that have different political views, we don’t grow as a culture or as a society.

In Online Spaces:

People will make mistakes online. They will say things that are unintentionally hurtful, or blindly offensive. This is different than someone being intentionally biased and rude. If the slander is intentional, it should be reported. If it is unintentional, even to the point of ignorance, we need to be more resilient about what our responses are. When every transgression is treated with an attack, the most severe/bigoted/rude/biased transgressions are not given the heightened alarm that they deserve. With lesser errors and mistakes, we need to let people have a venue to recognize their errors and invite conversation rather than damnation.

Growing up, I heard the playground retort to taunts, “Sticks and stones can break my bones, but words will never harm me.” We are past the era of letting nasty people say whatever nasty things they want, and just turning the other cheek to pretend we are not hurt. This is a good thing. We want to live in a world where that behaviour is not acceptable. But it does not serve us well to treat the attacker like they can not repent or be sorry. It does not serve us to let the words said hurt us too deeply. By being resilient we can speak up, clarify our perspective, and engage in conversations that help us feel empowered rather than victimized.

Resilience allows us to be strong, flexible, and engaged in a society that is the kind of society we want to live and thrive in.
