Data Point #934 Showing Why Teacher Education is Problematic

I was perusing the blog feed and I come across my favorite source for "interesting" teacher education issues. Okay, most of what he writes seems flawed, but at least he's advocating to "Burn The Textbooks, Shred The Worksheets, Teach Math", but I digress.

Click to enlarge that image.

It's measures of central tendency from a stack of pennies. How far down the list of values can you get before you reach an inconsistency in the numbers?

How is this a sample of what you, as a real math teacher, would want to show the world as exemplar of your students' work? Why would this page be the one that you put out to the world ... unless you were deliberately showing how you gave feedback, a la @mpersham's

The project itself is a fine one ... I did the same thing when learning to use Fathom, and I plan on using it with my class this year.  But, really, if showing teachers "cool" or useful projects, wouldn't you want to display ones that are at least mostly (>50%) correct?

While this page would be great to show the relationship between sample statistics and population statistics, it's not at all clear to me whether our blogger noticed any of the problems.

Here is the population, if anyone is interested:

Reason #438 why kids have trouble.

During the passing time, Student is telling a story of how she had $20 in her backpack and then couldn't find it. Thinks maybe her father took it when he drove her to her friend's house. Another kid chimes in, "Yeah, my father always takes money out of my purse to go buy beer."
Kind of a shame when they trust their math teacher more than their parent.

Why do Teachers Get the Summer Off?

Funny you should ask. We don't actually get the summer off ... the students do. Our time off is the logical consequence.

The reasons why are more interesting than the "It's a farmer thing" line of reasoning.
If Education Secretary Arne Duncan has his way, kids would be spending a lot more time at school — and a three-month summer would be a thing of the past. He continued by explaining that the American school calendar is antiquated and must be modified so that American students can compete at the highest levels internationally. “Most people realize that our current day is based on the agrarian economy, and we don’t have too many kids working out in the fields nowadays,” Duncan said. 

Most people realize, huh? Then most people would be wrong. And so is Arne.

The summer months are hot. The temperatures throughout the Northeast rise regularly into the 80s and 90s, the humidity is choking, and closed-in spaces like classrooms are no fun when you've got 25 kids sweating and fidgeting. It's bad enough in late May and mid-June.

In the late 1800s and early 1900s, when a lot of school policies were first considered, it was easier to heat buildings in the winter than to cool them in the summer because, you know, duh, there wasn't any air conditioning. Factories closed. Schools closed. Offices closed. Congress closed. Everything closed. People with the wherewithal escaped the cities and went to the Adirondacks or Vermont or the Catskills, with all their servants and entourage.  People who didn't have money went to Coney Island. That's why everyone traditionally gets two weeks in August ... because it's the worst damn time to be in NY and Boston and Washington D.C. and since that was where the decision-makers were, that was the decision. Time off for major holidays and the occasional week or two here and there - Thanksgiving, Christmas and Easter - and the rest is school ... and everyone escapes in summer.

Sorry to all you "It's all based on the agrarian calender" believers - it's obvious you were never on a farm.

Think about it ... if the whole thing was done for farmers benefit, wouldn't it make more sense to have the time off when the real heavy work was done on a farm? Like planting and harvest?

You don't see vacations in October, do you? You know, when the harvest occurs for most of the major crops in the northeast. Halloween and all the corn stalks and pumpkins -- ringing a bell?  Thanksgiving is in November - the only time you get is for the feast, not the work that leads up to it.

The summer months are busy (the definition of farmer is 'a busy man') but nowhere near as busy as other times of the year. About the only farm work done around here in the summer is haying, watching the corn grow and fixing stuff. 

I'm going to go out on a limb a bit here ...

... Kids need a break from school; we have to let them do things OTHER than school. You know that old saying, "Most of what I know, I learned outside of school"? That's a big part of what summer is about. Parents, by and large want their kids to have summer break, want their kids to be able to get a part-time job and learn to be responsible adults, be able to hike the Appalachian Trail, laze about or go swimming, etc.

And why should kids be in school for every week of the year? Shouldn't we let the parents raise them for a while?

There are some schools that have installed a full air-conditioning system and choose to go year-round ... but they still tend to stick to the same 180 days. The only difference is that they have more one-month vacations or they do a four-on, one week-off schedule.

If my school system ever decides to change to that, I'll adapt but I have confidence the students and their parents won't let that happen.

Regular Class work is so Helpful.

I find that a regular activity is a good thing. The students look at it as a useful digression and happily go about working on it ... then they realize it fits right in with what you've been doing.
@fawnpnguyen: "I was brainstorming with a couple of 6th grade math teachers at another district, and we were listing out a possible warm-up/math talk schedule, something like Monday: number talk; Tuesday: visual pattern; Wednesday: estimation 180; Thursday: fun fact, or WYR, or Keeping Skills Sharp, or SBAC/review question; Friday: personal reflection.
Here are a couple of those ideas and one or two others:

Estimation180 - building number sense by estimating values from images or video. This is valuable because so often we say "Does that answer make sense?" If the students have little to no experience with the subject of the question, and no practice making estimates, then answering our "Sense?" question is an exercise in random answer generation.

One Hundred and One Questions - An image or video is presented and students ask any question that comes to mind. While I personally wish the prompt was "What math question comes to mind here?", it is a good place to help them develop the ability to ask questions of the world round them and to see that math isn't just a classroom activity. Browse beforehand and record the links of the ones that fit your current material or your mood.

Math Arguments 180 - The goal is to have students question their assumptions and bring those assumptions to the front of their minds for conscious consideration instead of letting them hold on to common misconceptions that mess up their thinking.  Still in the development stages. The Math Concepts Challenge is also for teachers, though your students might be charged up for it.

Visual Patterns - Practicing the art of understanding the pattern and setting an equation to it in order to predict the value at step 43. I've been thinking it needs more patterns that aren't straightforward linear functions, but if that's the age you're working with then here is a bunch.

Math Talks - Prompts for discussion with your students.

Would You Rather? - students are presented with a choice. They choose and then have to justify their choice. "Would you rather have a bag of nickels that weighs as much as you do or a stack of quarters as high as you are?"

Graphing Stories - a video is shown and the students need to create a graph of some data from it. The video contains a graph blank that shows the independent and dependent variables. Usually, these are time-series graphs of height or altitude, but if you only show the "action" portion, you can have them graph whatever quantities that come to mind.

The UVM Math Contest - Problems from the University of Vermont High School Math Contest. These are given in the spring of Pre-Calculus and are meant for mature students who have had a good algebra II background. These questions are to be solved without a calculator or technology of any kind; figuring out the method is the whole point. Attempting a whole test in the allotted two hours would challenge even the best math teachers. Scores of 15 out of 41 are considered excellent.

Drilling basic facts pays off.

"Practice makes perfect."

Okay, we do have to differentiate between mindless drill & kill and what really makes kids better at math - focused practice, error correction, and repetition of correct processes.  Just as hacking around on a soccer field doesn't help the team nearly as well as a directed practice, endless pages of addition problems aren't useful in developing math skills.

Do ten at a time until you get them right. Examine the work, identify errors and don't repeat them .... which sounds like what Common Core asks math teachers to do and what math teachers have been doing for a long time.

This all sounds like what you've been doing, unless you have Curriculum coordinators like mine who denigrate practice as "drill and Kill. We should have the kids do critical thinking", as if critical thinking and error analysis were two different things.
"Healthy children start making that switch between counting to what’s called fact retrieval when they’re 8 to 9 years old, when they’re still working on fundamental addition and subtraction. How well kids make that shift to memory-based problem-solving is known to predict their ultimate math achievement. Those who fall behind “are impairing or slowing down their math learning later on,” Mann Koepke said. 
So, those teachers who insist that the kids should have a calculator and an internet connection so they can look it all up are really doing a job on their kids.
It turns out that adults don’t use their memory-crunching hippocampus in the same way. Instead of using a lot of effort, retrieving six plus four equals 10 from long-term storage was almost automatic, Menon said. In other words, over time the brain became increasingly efficient at retrieving facts. Think of it like a bumpy, grassy field, NIH’s Mann Koepke explained. Walk over the same spot enough and a smooth, grass-free path forms, making it easier to get from start to end. If your brain doesn’t have to work as hard on simple math, it has more working memory free to process the teacher’s brand-new lesson on more complex math. source.
So the next time someone says that elementary students should have a calculator, that "you can look that up" and "all we need is to teach them information retrieval skills", remind them that the brain needs to have some basic facts to work with before it can handle more complex tasks.

Currently, the argument point brought up here is the Japanese education system, which has been moving away from drill and practice and turning to the higher-order thinking that reformers here in the States are always going on about.

Remember, however, that a typical Japanese high school teacher does NOT have to do as much of this preparatory drill and skills practice ... because of the ubiquitous "jukus" - after-school academies that nearly every Japanese student attends to make sure that he/she has a shot at higher education.What do the "jukus" do? Drill. Basic skills. Practice, practice, practice. Because it works.

Here's a description of one of these "cram schools":
"This school broadcasts lectures to its 800 satellite schools all over Japan and supports students via telephone, fax and the Internet. Students can take math training menu and other drills on the Internet through a service called Toshin Home Lesson. They can choose from one series of lectures to a whole package."

50-cent solution to Car Seat Deaths

The Weather Channel has been making noise about kids left in carseats and dying from the heat ... an admirable cause, to be sure.  They had a short segment in which they talked to some people, ran a clip about some parent who forgot, and then tossed off an industry statement that "Monitoring the back seat for infants would be 'too costly'."

That is utter trash.

$0.50 and a bit of programming would knock down the rates by at least a half.

You know that beep that you get if your keys are in the ignition when you turn off the car and open the door?  It goes for maybe ten seconds and then the dome light and the beep shuts off.

Here's the Keep Your Child Alive Solution: (edited after first comment)
If the LATCH system has a seat installed, when you turn off the ignition or open the driver's door, a beeper located behind the driver (in the dome light or even further back) goes off for a few seconds. It has to be a distinctive beep and it has to come from *behind* the driver. If the LATCH system cannot have a sensor in it, then place a switch there that turns on the system when the seat is installed. Sure, someone could turn it off, but that would take a direct act.

That's all it would take. Most of these deaths are caused by harried drivers, in a rush, forgetting that their child is in the back because he immediately fell asleep and hasn't made a peep for the last thirty miles. A simple chirping noise from behind or a flashing light on the dash is all that the vast majority of these cases would need.

No child in the back carseat? So what? You still think to check.

You're getting out at the gas station? So what? You hear a chirping noise from the back and you remember he's back there. It will become instinctive for parents to hear the beep, turn and check.

All this BS with reminder cards and BESAFE lists? Useless.  It's not that parents don't care. They are forgetting that their kid is in the back - why would a checklist help?

Putting a stuffed animal in the front seat to remind you? Marginally better, until you have more than one thing in the front seat, or you forget to throw that toy in the front, or your son screams for that EXACT toy and you hand it to him ...

Hanging an air freshener from the mirror? In addition to it being illegal in most states and a bad idea to obscure your vision, this "reminder" is constantly in your field of vision and will quickly be ignored.

The car companies can put in 12 airbags that are linked to the seatbelts and pressure sensitive seat sensors, coupled with instantaneous triggering mechanisms, they have hundreds of computer chips that monitor everything about the engine, they are all furiously installing driver-distraction devices like phone and GPS screens and computer-driven window and climate controls that can't be operated safely while the car is in motion ... I think they can figure this one out, too.

Come on, car people. THINK.

The Highly Ineffective Principal: Clerical Error

A certain principal writes a letter for the school yearbook.  In his message, Roosevelt Principal Dr. Steven Strachan tells the graduates how proud he is of them and that they are a class of “great leaders, articulate orators, brilliant scientists, breathtaking athletes and extraordinary artists.”

He plagiarized the message.

Word for word. All of it.

From a principal in CA, uncredited.

But, but, but, but ... he "asked permission to quote"!

Here's the best part:
"I sincerely apologize to the Roosevelt community and to the class of 2014 for the inadvertent clerical error causing mistakes to be printed in the 2014 yearbook. An unedited draft of my remarks was accidentally published rather than the final version, and I take full responsibility for the oversight."
 Clerical error? A clerical error is misspelling the name of the guy you're quoting, or writing that the year is 2041. A clerical error is the yearbook editor rearranging the paragraphs inadvertently. A clerical error does not include you plagiarizing the entire message from another principal and then congratulating the WRONG SENIOR CLASS at the WRONG SCHOOL.
The Roosevelt principal even concluded his message like Barone did, writing, “Congratulations to the Albany High School Class of 2013.”

Blaming your plagiarism on the yearbook editor's "clerical error" is low-class, especially when you phrase it "clerical error causing mistakes to be printed." Passive voice apology fuck-you?

My favorite part of this is that he takes "full responsibility for the oversight." If one of his students did that, suspension would be in order. Nothing is happening to him ... he doesn't even have to pay the piddling amount of money for the reprint: the last line of the piece mentions that the pages are being reprinted with $800 from the "Principal's Discretionary Fund."

In case you're not familiar with public school budgetary BS, that's a slush fund that the principal may use at his discretion. Usually, it's used for things like buying a poor senior her cap and gown, or funding some low-income students tickets to a show that other kids are going to. Maybe supplying the SpecialEd department with some bit of tech that they can't get under normal budgets. Feel-good stuff or charitable-type things.

Educator of the Year.

The Daily Schedule, or Why do we do this?

When Amnesty International works to ban a practice in prisons, you might want to rethink doing it in schools.

My school has 1.5 hour blocks separated by 3 minute passing times.  Long ago, I began to tell students that I didn't want to know when or if they were going to the bathroom, just go one at a time and don't dawdle.

"It's none of my business. The pass is right there. Carry it to get yourself past the AP.  I don't need to know why ... TMI, people."

You know what? They go if they need to. But the vast majority doesn't abuse that and class runs just fine.

"I know that sometimes you don't really need to go, but that you need to walk down the stairs, across the building and up the other stairs and then back.  Just realize that when you get back, we will be focused on something and you'll have to pick up the thread quickly. Be ready."

Yes, I admit. That kid in the third row goes every day. He's a wanderer and the AP gets on his case and wants me to restrict his movement, but I refuse. Having him sit and fidget and whine will only distract everyone -- far more than if I just let him go -- and letting him get it out of his system means that he can focus when he returns.

If the situation calls for it, I will ask him directly, "Do you NEED to go? These instructions are important and you'll need to be ready to start this when you get back. Can it wait?"

I don't like it much but it's necessary. 

Admin bitches about tardiness, yet we give them 3 minutes to move two floors and across to a different building. We are told to stand at our doors so we can greet the students but also to monitor the hallway and ensure the kids are moving in an efficient way.

Admin stresses about teaching "bell to bell" -- for 90 goddam minutes -- as if the stresses we put on students don't count. "Teach to the bell" means that kids have to write, think, or be doing something right to the last second, then collect all their stuff, make it down the hall or further, get into the next room and be seated before the tardy bell.

In three minutes?

Why do we torture kids in this fashion?

They have a cup of coffee in the morning to help wake themselves up ... and caffeine is a diuretic. who in their right mind thinks that students will be able to take care of business AND walk to the other building in just three minutes?  Apparently, we do.

At lunch, many will down a 3/4L bottle of Gatorade.

We're all instructed to let the kids drink as much water as they want. We're reminded that 8 cups of water is necessary, so water is the only thing we're all supposed to allow in class -- and many students have a water bottle and the school just installed those nifty water fountain extensions with the reusable bottle filler spout thing.

But you can't go to the bathroom? Does anyone understand how the human body works?

Apparently not.

What brought this up?  Taught by Finland, "For every 45 minutes of classroom instruction in Finland, students are entitled to a 15-minute break. This is guaranteed by law!"

I love this guy. He's an American teacher who moved to Finland and is a teacher there. Well worth reading regularly. What set him off? This Chicago Administrator's note:
In addition to scheduled restroom breaks, students will be given restroom passes to use if they need to use the restroom outside of the scheduled time. Students will be given two restroom passes to use between now and the end of the quarter. They can choose to hold on to them and trade them in for a reward at the end of the quarter. Following these guidelines:

Have students fill in their names as soon as they receive them. Passes are invalid if names are crossed out for another name.

 For the upper grades, students can use one teacher's pass in another classroom, but they still only get the same number of passes per quarter.

 Use a class roster to have student initial next to their name to indicate that they received the passes.

 Have students fill in the "time out" and "time in" and then turn the pass in to the teacher when finished. This will help them practice the [Common Core Standards] of telling time with both digital and analog clocks.

 Promote the benefit of not using the passes by reminding students that rewards will be given for left over passes at the end of the quarter.

Teacher Preparation in the US

from Pasi Sahlberg
In the United States, for example, there are more than 1,500 different teacher-preparation programs. The range in quality is wide. In Singapore and Finland only one academically rigorous teacher education program is available for those who desire to become teachers. Likewise, neither Canada nor South Korea has fast-track options into teaching, such as Teach for America or Teach First in Europe. Teacher quality in high-performing countries is a result of careful quality control at entry into teaching rather than measuring teacher effectiveness in service.

Questions for your 1:1 Initiative.

Although I suspect that a great deal of planning has gone into this initiative already, here are 10 important questions that parents should ask—and that school administrators should be able to answer.
  • What are the initiative's teaching and learning goals, and how will those goals be measured? Too many technology initiatives start with the technology, not the instructional goals. Clearly defined objectives should drive the choice of device being used. For example, if schools want students to read e-books, the screens and applications should support this use. In the planning stages of the project, the district should also determine how it will measure progress toward its stated goals, so that it will be able to answer the question, "What have we received for our money, time, and effort?"
 We went for the keyboard, low cost, natural integration with the Google suite ... Chromebook. After an initial bad phase of damaged hardware, it's evened out. Curriculum, teaching goals, measurement -- eh, not so much.
  • What training is in place for the teaching staff? Professional development is key to the success of any 1:1 initiative. The major shortcomings of most 1:1 professional development efforts are that they offer too little, too late—and focus too much on the device instead of on the pedagogy required for its effective use.
Damn little in our district. It's been hit or miss and mostly miss. Fortunately, there are a few people willing to train each other but that is an uneasy way to do this.
  • Is there a digital citizenship curriculum in place? Of utmost importance to many parents is their children's online safety. Schools can address this need by having a good plan in place to help students learn to use technology appropriately. Supplement the plan with a parent education program that includes guidelines—written in clear, understandable, and positive language—for when devices can be used in school, what applications and websites are appropriate, and how users must care for the equipment. (Our district's guidelines can be found on our 1:1 parent site. Like many districts, we have borrowed extensively from Common Sense Media.)
No. The AP will try to discipline students who cross an ill-defined line, but there is nothing in place that sets out any rules or guidelines to limit the students nor is there anything to guide them in using it more fully than for music videos.
  • What happens if a student breaks or loses the device? Clear procedures related to loss, damage, and theft of school-owned devices need to be in place. My own district, like many, offers parents a low-cost insurance plan that covers accidental damage. We also place mandatory, heavy-duty cases on student devices, dramatically improving their survivability.
We've got this covered. Admin tried to "go easy" at first and that was a total failure. Now that they have simplified things (replacement screen is $50; tough, you broke it, you pay) students are much more self-assured and they've come to understand what kinds of treatment will end up costing money.
  • How will these devices be managed and maintained? Unreliable technology is frustrating for both staff and students—and apt to go unused. The 1:1 plan should address the staffing and management systems necessary to troubleshoot hardware, update software, and install applications on student devices.
Yeah, covered. Important point.
  • What e-resources will accompany the hardware? Individualized instruction requires such resources as e-books and content databases, a course management system like Moodle or Blackboard, and software that enables students to access and process information. Cloud-based productivity and collaboration tools like GoogleApps or Office365 can support workflows and communication between teacher and students.
Google Applications Suite, Apps, Moodle (that I personally maintain, installed, support).  Yeah, this part is working really well for the faculty who've jumped in feet-first. For the others, it's been a struggle ... some people still want paper for everything.  The students are good for this. "Can I just share my paper?"
  • Is the network infrastructure in place to support the use of the devices, both internally and in the cloud? Although many schools have spent a good deal of time and effort in extending the reach of their wireless networks to all instructional areas of a school (coverage), they may not have the bandwidth needed to support dozens of devices trying to use the network at the same time (capacity).
Barely. Still takes time in the morning to navigate the wifi discovery, network login, etc. Once that's done, it pretty good. "Take out your Chromebooks." 30 seconds and we're using Desmos.
  • How will you ensure that all teachers use the devices to improve teaching and learning? Few of us like top-down mandates, so it's important that the teachers who are expected to implement this program have input during the planning process on goals, training, resources, and policies. Assessment of effective teaching using technology should be embedded in teacher evaluation practices.
First year ... a few teachers, most of the students. It's going pretty well and it's a definite positive slope.
  • What will happen in a few years when all these devices are obsolete? The plan should be specific about the project's long-term viability. Using one-time referendum dollars that will be repaid over 20 or 30 years to buy equipment that will need to be replaced in five years is like taking out a mortgage to purchase a car. A transparent budget for the project must clearly state both annual costs and long-term maintenance and replacement needs.
 It's handled.
  • Are other areas of the school's budget being cut to pay for this project? If the 1:1 initiative is being funded by general operating dollars, school leaders should be up-front about its potential impact on other programs. Given the zero-sum nature of most school budgets, somebody's priority program or resource may get reduced—and that somebody may not like it. If dollars are coming from places that will require less funding because of the initiative—such as textbooks, printing, or school supplies—the district needs to demonstrate these savings.
Nothing is being cut ... yet.  The textbooks are being replaced in part with FOS .... there are lots of math books out there. Some paper books that have  deteriorated over the years are being replaced - but pdf or active versions, rather than paper. We saved money by not buying the expensive version.

I think our feeling is that we'll save a little here and a little there while providing the students with tools they wouldn't otherwise have been able to get. It might not be a monetary zero-sum, but the benefits are worth the cost even though we haven't come close to fully utilizing the resource.

Things We Need You to Stop Saying, part 1

There are a couple of things we really need you to stop saying. The first:
"The right answer isn't important. It's knowing what you're doing."
No matter how you parse this, it's ridiculous. The right answer is the whole point of doing the problem ... has always been, is now, and will always be. The "knowing what you are doing part" leads to the right answer. If it doesn't, then you don't know what you are doing.

Variations on this include: "It's the concept that matters" and "We're putting the emphasis on the method." It shows up as sarcastic responses from Institute Professionals and college professors, too:
What we should be saying is "The right answer is vitally important ... so important that we also want students to explain the method and how we all know the answer is correct; they must be able to detect an error if it occurs and describe how to fix it so that the solution IS correct."

If you go to the trouble of having the students communicate, verbally or in writing, how they solved a problem, then you are focused on the right answer ... there would be no need to explain anything, or fix errors, if you didn't care about it. You'd take any randomly achieved answer as long as it was correct, and move on.

Just cancel the 6s.

Does anyone ... ANYONE ... seriously think that the right answer doesn't matter here? I don't consider this a "right answer" even though it looks like it.

I'm going with "No."
You'd take a wrong answer that looked like a right answer if you weren't paying attention.

Just cancel the x² from numerator and denominator.
One hallmark of mathematical understanding is the ability to justify, in a way appropriate to the student’s mathematical maturity, why a particular mathematical statement is true or where a mathematical rule comes from. There is a world of difference between a student who can summon a mnemonic device to expand a product such as (a + b)(x + y) and a student who can explain where the mnemonic comes from.
That is a far cry from " The right answer isn't important."
For example, mathematically proficient high school students analyze graphs of functions and solutions generated using a graphing calculator. They detect possible errors by strategically using estimation and other mathematical knowledge.
You can't detect errors unless you know the right answer, or at least have a sense of what that right answer should be.

Even the infamous "Letter to Jack" assumed that the kid could get the right answer, then could find the error made by the other kid ... the assignment took this two steps beyond the right answer: explain the error to the other kid and help him fix it.

JD2718 banned FOIL, Dan Meyer used immediate feedback, countless teachers rearrange PEMDAS (as BEDMSA) to avo
id this:

We need them to explain what and why.

I often "let them in on a secret" and share the mnemonics after they get the understanding ... especially if the mnemonics speed up computation so we can get on with what we are actually doing, but every teacher worth his salt knows that you have to periodically make sure that random, blind luck isn't at play.

The last reason that we need to stop saying "The right answer isn't as important as knowing what you're doing" is that too often we teachers are speaking to people who don't know that it is merely step 1, namely school boards, administrators and parents.

I watched a young teacher from another school give a presentation to her school board. Among other weird things, she came out with this statement ... immediately, board members latched onto it.

"What do you mean? Of course the right answer matters."
"I've been in business for forty years; every time, the right answer matters."

She doubled down ... "No, they need to know HOW they are solving the problem." No one was buying it, nor should they have. Whether she didn't understand their concerns herself or honestly didn't believe that the right answer was so vital, she certainly couldn't communicate her stance to the Board.

A blind acceptance and repetition of poorly-understood Twitter broadsides and mindless slogans is the rhetorical equivalent of canceling the sixes.

That makes us all look bad and we're gonna need you to stop saying it.

Doing Things the Hard and Expensive Way

So this school had an election. Desperate to justify their purchase of enough TI-Inspire Navigator calculators for the whole school, they used them for voting for StC, because apparently:
  • the cellphone that every kid carries around were ... IDK ... banned, 
  • the free website was shut down undergoing maintenance at that exact moment, as were all of the similar, related websites, also free. .. like SurveyMonkey.
  • Google Forms was suspiciously locked and inaccessible ... 
  • the supplies budget didn't allow for 100ct note card pack at $0.39 per ...

but did allow for the Inspires:

For this misuse of funding, we hereby award them the US Armed Forces Monetary Memorial Medal, emblazoned with the image of Our Rich Uncle Pennybags.

Snap Judgements

I love the kinds of conclusions people make on Twitter.

"Which looks more like a 21st century classroom?"

Neither. They're booths at a conference. I understand that the snap judgement goes against the top booth because the 21st century classroom isn't supposed to be about one person "lecturing" and 30 students quietly absorbing new information without "collaboration"; it's also missing a lot of misunderstood 21st Century Learning New-Age Idealistic Pedagogical

But I digress.

In the Upper portion of the composite photo, we see a booth set up to present a lot of information. The people are encouraged by the layout to be seated, which means that they can all see because they out of each others way; no one is standing in front of the screen.

Think about this for a second. TI has a mission: sell calculators, at $150 each, with crappy screens and SLOOOOOOOW processors. They need to get you in a seat and show you the WOW factor. They need to get you past the basics fast and sell you on the tech because that $4500 classroom start-up fee is huge.  "Those regression functions don't come cheap, and aren't in any other package."

This is crying out for exactly what they've got here: a booth with a presenter who knows the machine inside and out, delivering information to as many people as they can, as efficiently as they can, in as little time as possible.

You put them in a seat where they can set down their stuff, see the big screen, write something down if they want to, hold the Inspire, swap out the faceplate, photograph it with their phones, set it down and tweet about it ... tables and chairs arranged in an efficient pattern, making best use of the space. Additionally, once seated, it's tough to leave politely before the end of the spiel and it's easy to control the technology and prevent theft.

Over on the side, some tall tables (which don't force you to lean over) for people who are browsing and don't want the whole presentation, or who want to stand and watch from the side.

BOOTH SCORE: 8 out of 10. Great for information transfer and for sales promotion. This booth is designed to have you linger and explore, try out and figure out, and to convince to you agitate for a major purchase back at your school.
CLASSROOM SCORE:  7 out of 10. "Boring" if you are looking for new-age learning styles, but effective as an organized setting for 30.

In the lower one, there is a guy on the left, holding a laptop in an awkward stance. One of the people he's talking to can see the screen. The other one can see the keyboard and be part of the conversation but unless he leans in and gets in the way of the other listener, he can't see much.

In the lower right, three people are crowded around a computer that desperately needs to be on a higher platform because all the people who want to look at it are standing -- it should be at eye height or, if not eye height, at least not "lean over and peer through the top part of your bifocals and then crane your neck back so you can see through the lower half of your bifocals" height - as the guy in white shorts is being forced to do.

In summary, a badly designed booth for this function, unless that function was "quick information shot and move on." This booth is designed to NOT allow you to linger and deeply explore the product.

There is no marketing director here trying to maximize anything, because there doesn't need to be. They only need to let you convince yourself that Desmos is cool - it is its own selling point. The website is free and doesn't have a large initial classroom purchase required, as TI does.

As a classroom, this booth is crap, too. There's nowhere for people to get comfortable. There's a giant graphic with some expression art. The displays / workstations are placed too low without any chairs so students have to type at weird angles. If the intent was for people standing, there should be some podiums so they can set down their devices and use both hands. If the intent was for people to sit, then the tables are at the right height, but there are no chairs.

This would be a horrible "classroom" for teacher/guide or for students.

BOOTH SCORE: 3 out of 10. (or 8 out of 10, depending on intent)
CLASSROOM SCORE:  1 out of 10.

But I guess I don't see things in the same way as other people do.
