An Exceptionally Simple Class Grade Distribution Chart for DCPS Teachers

This is the latest in lame GSheets hacks I put together for Kelly.

Every Monday, she hands out progress reports. And every Monday, two manners of delusion ensue:

  1. The kids who are doing poorly assume that they’re doing no worse than anybody else (the system must be biased!)
  2. The kids who were doing well but have been slipping assume that they must still be at the top of the heap, because they’re the smart kids so of course they are.

Wouldn’t it be nice if you could point to a classwide grade distribution to show where each student fits in the grand scheme of things?

Indeed it would.

Enter, the grade distribution chart.

It’s driven by this GSheet, which simply takes grade reports from Aspen and turns them into stacked dot charts that can be printed and stapled to your data wall (remember data walls?). You can’t see it in the sample, but there is also a dot at the class average.

It’s anonymous, but as long as the students have their progress reports (which shouldn’t be a problem given that this is generated from them), the kids can see exactly where their grade stacks up against their peers.

The biggest utility, though, is for classes who remain convinced that they’re “the smart ones” and thus must always be at the top of the heap. When they inevitably try to rest on their laurels, it’s always satisfying to show them getting blown away by the “earnest plodders” in the remedial group. ūüôā

So, how do you use this beauty?

Two sections follow: initial setup and regular use.

Initial Setup

  1. Open the template GSheet. Make it your own by clicking File | Make a Copy.
  2. Rename the tabs to match your section numbers. Stick with the existing syntax since the other sheets are designed to expect an A-B section number syntax.
    • If you need more than 5 sections, just click on one of the tabs and choose Duplicate. Remember, though, that you need to do this 2 times: once for the Raw sheet and once for the Chart sheet.
    • Further, you’ll have to direct the Chart sheet to the appropriate columns in the Data sheet. In short, you may need to get in touch.
  3. Go to the Data sheet and change the titles, making sure to retain the format of Course A-B with section numbers.
  4. Update the titles of each chart sheet appropriately (alas, there’s no easy way to make them auto-update).

Regular Use

  1. Open Aspen and navigate to the Gradebook for a particular section.
  2. Load the Scores page.
  3. Run the Assignment History report.
  4. Set the format to CSV and accept the warning.
  5. Open the report file in Excel.
  6. Click the top-left chiclet (the gray square between the headings for Column A and Row 1)
  7. Copy to the clipboard.
  8. In the GSheet, open the appropriate Raw tab.
  9. Click the same top-left chiclet to select everything.
  10. Hit Delete to clear out the old data.
  11. Click Edit | Paste Special | Paste Values Only to paste the data.
  12. Repeat for the remaining sections.
  13. To Print, open the appropriate Chart tab.
  14. Hit Ctrl-P to get to the Print Preview dialog. The charts are formatted in Landscape for improved visibility.
  15. Click Next to get to the Print screen.
  16. Print per usual.

One Billion URLs

Last night I archived my billionth shortened URL for ArchiveTeam’s URLTeam project.

The rig that runs these is pretty fun, and I may post about it. But for now, I just find 1 billion URLs to be cool.

#PublicSchoolGrad / #PublicSchoolSuccess Image Generator

It returns!

A couple weeks ago, Diane Ravitch sent out this tweet:

So of course it was time to dust off the #PublicSchoolSuccess image generator.  I made a few updates, including a new color scheme.  Also, since my coding abilities remain complete shite, I threw the code to GitLab so others may modify it.

Credit remains with Shane Chism for the original code.

New Site

New theme, and purged some old posts that weren’t working. May make some updates going forward. Let’s see how this works.

Fuze Card Saga Pt. 2: Wake Up, Please

Today’s episode: in which our hero attempts to turn the card off, and then back on. Hilarity ensues.

After about an hour with the Fuze card, I had managed to pair it with my phone and add a collection of credit and debit cards.  Before heading into the wild, though, I want to see how long it will take to pull up a card under normal use.

So, we power off the card and power it back on.

Great.

Issues Powering on the Fuze Card

I have no idea what causes this or how it’s remedied.¬† What follows are my observations, which somebody smarter than I can hopefully decode:

Guaranteed way to replicate

Continue holding the Power button for a few seconds after the card has powered off.¬† This will stall the card for about a minute.¬†¬†I want to say that there’s a buffer getting filled up, and in sleep mode the clock is slowed down to the point that the buffer takes eons to clear.¬† But I have zero proof for this.

Duration of issue

I’ve had times when it fixed itself after 2 minutes; others when it took days.

Fuze Card’s Response

Provided I could show video proof of the card sucking, they were happy to send a replacement.  Fortunately, it took 2 weeks for my lazy self to get around to mailing in the card, and when I took it out to confirm the problem, it booted with no issues.

The charger may have an effect

A few times, topping the card off in the charger fixed it right up.  This is probably a coincidence, though.

At least it works now

Since it magically awoke after that 2-week slumber, the Fuze card has worked just fine.¬† I can get it to freeze up by mashing buttons after power-down, but unless I’m¬†trying to make it freeze, no further issues.

More Surprises in Store

Once the Fuze card awakens and powers up properly, there’s still fun to be had.¬† Stay tuned.

Fuze Card Saga Pt. 1: Unboxing & Trying to Add Cards

November 8, 2017: The Fuze Card finally arrives.

First impressions

It’s thin. Like, credit-card thin.¬† No idea what wizardry was used to fit a battery inside the thing, but they pulled it off.

It’s soft(?).¬† The matte plastic feels soft – at least softer than a rigid credit card.¬† It doesn’t seem bendier or in any other way more deformable than a regular card, but it somehow¬†feels like it should be.¬† Go figure.

The buttons are raised, which does create worries about wallet misfires.¬† I keep my wallet in my back pocket, where it’s often sat upon by a profoundly bony backside. The buttons do require a decent amount of pressure to push, though, so this may not prove to be a problem.

Getting it Connected

Cards are added via the companion app, which loaded up with no issue.  The card connects automatically via Bluetooth Low Energy, though you can also force it into pairing mode by holding the Power and Multi buttons simultaneously.

Once connected, the app instructs you to set up a passcode, which is just a 6-button sequence created by the three hardware buttons.¬† At \(3^6=729\) possible combinations, the passcode isn’t exactly guess-proof, but then again neither is a stolen credit card.¬† And the Fuze card has other security measures as well.

Adding Cards

This was a pain in the ass.

Cards have to be added using an off-brand Square reader which connects via the headphone jack.¬† First problem: I bought an Essential phone yesterday, and it doesn’t have a headphone jack.

The card reader (right)
and the Fuze charger.

The Essential does, though, have a USB-C to 3.5mm adapter, which is nice.¬† Problem is, I can’t get it to scan for anything.¬† Worse, I don’t actually¬†own any wired headphones, so I can’t diagnose whether the culprit is the app, the reader, the adapter, or the phone.

Fortunately, I still have my old Nexus 5X, which does have a headphone jack.  This would be an opportune time to troubleshoot the USB-C adapter, but no. I just want to load my blasted credit cards.

Edit: The USB-C adapter also failed on the Nexus, so either it's defective or I'm doing it wrong.

Speaking of loading those cards:

Why can’t I just photograph the card, or manually enter the information into the app, a’la Android Pay?¬† Maybe requiring the reader is a form of fraud prevention, forcing you to have the actual card?¬† But even then, I could just use a card writer to make a physical copy of a stolen card – and I’m sure emulators exist as well.

Mercifully, the Nexus can read the cards and add them to the app, which syncs them to the Fuze card.¬† At least¬†that’s out of the way.

With the cards added, the next step is to test basic usability.  Hilarity ensues.

#DumpDeVos Caller Guide

Step 1: Call Your Senators

Use Call My Congress (opens in a new window) to look up your senators.  Use the links to call them.  (Note: confirmation of presidential appointees is a Senate process, so there’s little your other representatives can do here.)

Script #1:

My name is _____ and I am calling to let the Senator know that I would like him/her to oppose the appointment of Betsy DeVos for Secretary of Education.

I believe in my community‚Äôs public schools. Betsy DeVos believes in school privatization and vouchers. She has worked to undermine efforts to regulate Michigan charters, even when they clearly fail. The ‚Äúmarketplace‚ÄĚ solution of DeVos will destroy our democratically governed community schools. Her hostility towards public schools disqualifies her. I am asking the Senator to vote against the confirmation of Betsy DeVos.

Script #2:

My name is _____ and I am calling to let the Senator know that I would like him/her to oppose the appointment of Betsy DeVos for Secretary of Education.

DeVos and her family heavily lobbied the Michigan legislature to shield the charter industry from greater oversight. She pushes for-profit charter schools and online schools, which consistently fail the students that they are supposed to serve.

I want my tax dollars to stay in my community to support my public schools. I don‚Äôt want my money going to private schools and profit making scams. Betsy DeVos is bad for American education. I am asking that the Senator oppose DeVos.


Step 1b: Send a Video to Your Senators

Use Countable (embedded at right) to send a video message to your Senators as well. Personal story > telephone script.


Step 2: Help #DumpDeVos Gather Steam

Step 2a: Retweet a Badass Teachers Meme


Cruise through the Twitter history of #NotMySOE, pick a meme, and retweet it with the hashtags #DumpDeVos and #NotMySOE as well as #TBATs.  Consider tagging the aforementioned Senators as well.

Step 2b: Remind People that Public Schools are a Success Story


If you haven’t already, create a #PublicSchoolSuccess picture and tweet it out using said hashtag.  (Soon to be added) are lists of people who have either a) allied with Betsy DeVos, or b) have claimed public schools to be a failed experiment.  Tag as many as you reasonably can.


Step 3: Acknowledge That She’ll Probably Still Get Confirmed.

Stick with me, here.

Let’s just face the facts.  There is basically 100% likelihood that Betsy DeVos will become our new Secretary of Education.  Reasons:

  • In the history of the United States, just 9 nominees were rejected by the Senate, and only 13 withdrawn before confirmation.
  • The major way to knock someone out of contention is with flagrant conflicts of interest, and that’s far more likely to be a Rex Tillerson fight.
  • Jeff Sessions and Michael Flynn represent far greater threats to the rights of the oppressed, so resources will go to those fights.
  • School-choice ideology aside, this is a partisan nomination and a partisan confirmation.  And have you seen the Senate make-up?  Related:
  • Harry Reid basically made it impossible for the minority party to stop cabinet appointments.  Whoops.
  • Whatever GOP senators might be persuaded by reasoned arguments against DeVos have probably been bought.
But that doesn’t mean it’s over.

In 2018, all of the House is up for re-election.
As are 36 states’ Governors.
As are hundreds of state legislators.
And thousands of school board members.

The privatizers aren’t stopping after the DeVos hearing, and neither should we.


Step 4: Gear Up for the Long Haul

Step 4a: Join the Badass Teachers Association

Both the national organization and the one for your state.  This is where grassroots activism starts.  Read their blogs. Link up on Twitter.

Step 4b: Look Up When Your Senator is in Town

Go back to Call My Congress and go to your Senator’s page.  Find his/her Town Hall schedule (they all go by ridiculous cutesy names so you’ll have to search a bit).  Go there and hold them accountable, not just for the DeVos hearings, but for their commitment to public education.

Step 4c: Read the Diane Ravitch Canon

Or at the very least, The Death and Life of the Great American School System.  And once you’ve read that, memorize every data point from Reign of Error.

Use these talking points often.


Step 6: Have a Lovely Beverage

You’ve earned it.

#PublicSchoolSuccess App – The Details

The #PublicSchoolSuccess Image Generator app is located here.

This page is just the code behind it.

If that’s what you’re after, read on.

Credit Where It’s Due

This is all based off of existing code by Shane Chism, namely his Facebook Picture Overlay¬†script. ¬†Shane’s script is designed to do those icon overlays that you see on Facebook every time there’s a new social cause. ¬†It overlays a small transparent .png in the lower-right of an image, and makes sure the whole thing fits in a 200×600 frame.

Shane’s code still comprises >95% of the code in use, so major props to him for making something so easy for me to modify, and for being a mensch who gives it away for free.

The Modifications

The original script works like this:

  1. Resize and crop the source image until it fits in a 200×600 boundary box.
  2. Create a canvas the same size as the source image.
  3. Insert the source image into the canvas.
  4. Overlay the icon in the lower-right corner (a programmable offset is also available).
  5. Convert to JPG, timestamp, and save.

The #PublicSchoolSuccess version works similarly, but with a couple changes in workflow:

  1. Resize and crop the source image until it fits in a 300×450 boundary box.
    • If the image is portrait, set the width to 300 and crop the bottom to make the height 450.
    • If the image is landscape, set the height to 450 and crop the right to make the width 300.
  2. Rotate the source image to match the angle of the frame.
  3. Create a canvas the size of the overlay (which is the size of the finished image).
  4. Place the rotated/resized portrait on the canvas.
  5. Place the overlay on the canvas.
  6. Convert to JPG, timestamp, and save.

The Code

After this project, I am up to all of 8 hours of php programming (if you include time spent scuzzing with the image to get the right angles and locations). ¬†As such, I make no promises about the quality or reliability of this code. ¬†I did my best to emulate Shane’s methodology for the sake of consistency. ¬†Still, I’m sure I flouted plenty of conventions and eschewed plenty of efficiencies. ¬†Meh.

The package comes in 4 parts:

  • uploader.html – what users actually visit
  • uploader.php – uploads the user’s file and triggers processing
  • YearbookPicOverlay.php – does the actual processing
  • success.html – displays the result to the user

I also modified the .html files to make them look better, but since said modifications are entirely dependent on my site’s css, there’s really no point to including them.

#PublicSchoolSuccess Image Generator

The amazing people at Badass Teachers Association put together an excellent Twitter campaign featuring notable public school graduates.  Some examples:

 

To make something like this go viral, though, will take thousands more contributions.

So, I threw together an app that will let people add their face to the image and post it to their favorite social media.

The #PublicSchoolSuccess App

Step 1: Go to adamlabay.net/fbtag/uploader.html

Step 2: Upload a picture of your face.

Step 3: Save the resulting image.

Step 4: Tweet it to @BetsyDeVos and make sure to use the hashtag #PublicSchoolSuccess. If you have the space, copy @BadassTeachersA as well.

Step 5: Spread the gospel.

The Code

To be clear, I did pitifully little to create this. ¬†All the grunt work was done by Shane Chism¬†and I just tweaked the code. ¬†That said, if you want the gory details, I’ll post them shortly.

PowerSchool ISA Report for DC Schools

If you’re a DC school that uses PowerSchool as your SIS, then you’ve probably faced the situation where none of the attendance reports properly match the In-Seat Attendance (ISA) reports in Qlik.

I still can’t speak to the exact mechanics of why the two reports differ, but to bridge the gap I put together a report for the SQLReports4 package that calculates ISA using the same method as Qlik.

A few notes:

  1. All students need to have a Full-Time Equivalency (FTE) assigned. ¬†Generally, this happens by default when a student is added to PowerSchool, but sometimes it doesn’t register.
  2. The report’s first parameter lets you decide whether to report Year-to-Date or over a date range.
    • Both cases will return the ISA% by month and grade.
    • If the date range is specified, grade and schoolwide values for the range will be returned.
    • If the date range is not specified, grade and schoolwide values YTD will be returned.

The code:

<ReportName>In-Seat Attendance</ReportName>
<ReportTitle>In-Seat Attendance</ReportTitle>
<AfterTitle></AfterTitle>
<ReportGroup>Attendance</ReportGroup>
<ReportDescription>%ISA [(Students Present * Days Present)/(Students Enrolled * Days Enrolled)] per grade, per month.</ReportDescription>
