Assignment Submission Forms

Did you miss the Ditch Textbook Summit last month? Matt Miller has reopened access to all 35 videos from January 10 to 18. There's some great stuff there, including downloadable notes and certificates of completion. Click here to sign up. If you miss it, you'll have to wait until next December.

I gave a (slightly overlong) webinar to a group of TDSB teachers about Google Drive in December, and one of the things I mentioned is that the "Shared With Me" folder is.... well, it can be a bit of a mess. Mine is, at any rate, and last year I was finding it more and more challenging to find and then systematically open any documents students shared with me, especially since I told them to deselect the "Notify me" option when sharing. I told the webinar group I would blog about how I use Forms and a Sheet to make my life easier.

Very simply: when students write up an assignment (using Docs, Sheets, Slides, etc.), they share the link with me (making sure I have edit access so I can view their revision history and make comments). I've put the link to the form on the course webpage, and also in the body of the assignments.


I have the settings set to collect their email addresses (which in the TDSB includes their first and last names), so I don't bother asking for that separately.  I have a drop-down menu which is populated using the formRanger add-on for the assignment name, but you can just keep adding to it in the form itself. Then all they need to do is copy the link for their document. I set up response validation to "url" so that I get a clickable link in the response spreadsheet. I only have one section of each of these courses this year, so I've deleted that question from my forms to keep it simple.


Under Presentation, I select "Show link to submit another response", and I always write a personal confirmation message. For this form, it is "Thanks! Your assignment has been submitted to Ms. McPhee. You can continue to make changes to it until the due date." I've got some students who want to submit the url at the beginning of the assignment and some who prefer to wait until they're finished, and this works for both.


Under Responses, I select the response destination to be a spreadsheet. I've got all my submission forms going to the same spreadsheet so I only have to go to one sheet, but you can make a separate sheet for each form if you like. 


In the response spreadsheet, I created a new tab called "Marked?" and use the query function to bring the data into the new tab: in A1, put

=query('Form responses 1'!A1:E)

I then add a new column called Marked? at the end, and use Insert Tick Boxes to populate the cells with tick boxes.

If you want to sort into different sheets by section or even by assignment, then create a tab for each one and then use the following query in A1 of each tab:

=query('Form responses 1'!A1:E,"Select * where C = 'section-code-here'",1)

or

=query('Form responses 1'!A1:E,"Select * where D = 'assignment-name'",1)


where 'section-code-here'/'assignment-name' matches one of the values in your section or assignment questions. Here is a video explaining how to sort form responses using Query if you want to get fancy. (Warning: the tick boxes will be static, so if you reorder the rows or do some filtering by date or section or what-have-you, the boxes will stay ticked or unticked and won't move with the rest of the row.)

When I mark the assignments, I just click on the link to open their document. I usually have a spreadsheet rubric open in a side-by-side window, so it's easy for me to go back and forth, and it's really easy for me to tick off that I have marked an assignment and open the next student's. I can also add little comments to myself on each assignment in the cells to the right of the tick boxes.

I know Google Classroom is set up to not need all this, but I've only started using Google Classroom properly with one class this year, and I'm not loving the way they do assignments from my end. It could be because I'm not as familiar with how it works yet, but I think my solution works better for me. YMMV.

My next step is to set up a link to this in my assignment tracker sheets so it will automatically show whether they have submitted an assignment.

Note: you could have them submit Word documents, Excel spreadsheets, pdfs, jpgs, etc the same way, except that instead of a short-answer question, choose File upload. The files will get uploaded to a subfolder in the Drive containing this form, and you'll get a link to the file in the spreadsheet as before.

Here is a copy of a sample assignment submission form (including a file upload question, which I don't actually use) and the associated response spreadsheet, which is also where formRanger finds the assignment names.

Let me know if you have any questions or comments.

How to make a (quasi) box plot in Google Sheets

Want PD? TDSB Teachers should sign up for the TEL workshops on K2L. I'm presenting Getting More out of Drive as a webinar December 13, and there are plenty more workshops on offer. For everyone else, the Ditch That Textbook Summit is back. Free webinars! I will eventually blog about what I got out of last year's summit. Which was a lot. And Kyle Pearce and Jon Orr, the guys behind Make Math Moments that Matter, are having a Winter Holiday Giveaway! Win a spot in the MakeMathMoments online workshop, Wipebook packs,  their favourite books, ZorbitsMath licenses, Knowledgehook Store Credit!

I'm teaching MDM4U (Data Management), MAP4C (Grade 12 College), and MBF3C (Grade 11 College Math) this year (as well as three other courses, which perhaps explains the lack of posting). They all deal with, in one form or another, statistics. We're mostly using Fathom in MDM4U but for the other two courses I want to get them using Sheets, since they are more likely to see spreadsheets in the future than a proprietary statistical software.

One of the big downsides to stats in Sheets is the lack of box plots. Sadly, the apparently amazing Statistics add-on is not supported anymore, so we're stuck with what Sheets provides to us. Candlestick chart, which are intended for stock prices and graph low-open-close-high, could be used, but they are only vertical and don't include the median. You also need to put the data in horizontally, which I find counterintuitive.

minimumQ1Q3maximum
height B (cm)150168.5181198
height A (cm)137151.75174.75194

They do give you a quick overview of the spread, if that is all you want.

There is a way to get something more box-and-whiskerish, and it's error bars to the rescue again. Here, we use a stacked bar chart:

It is by no means perfect, since the 1st quarter whisker is doubled (and as you can see sometimes goes past the box into the 4th quarter) and the 4th quarter whisker is reduced to a mere tick at the maximum value, but I think it does very nicely. I'm actually thinking it might be a better way to teach box plots, since there's a bit of prep to do beforehand that might make students pay attention to what it means. I haven't coded for outliers yet, and I think that will be less straightforward to include. Also, I don't think this will work at all if you have any negative values.

I am a little worried that some of my students will be confused by that extraneous right whisker in plot B, but we'll see.

To plot the data, you need to add an additional column per plot, like so:
          J            K           L          M          N           O
    1ABAB
    2Minimum137150Minimum137150
    3Q1151.75168Q114.7518
    4Median164175Median12.257
    5Q3174.75182Q310.757
    6Maximum194198Maximum19.2516

The italicised numbers on the left are the what you would expect to plot on a box plot. The bolded values on the right N1:O6 are what you will actually plot. They are just differences between the points; J3 is just Q1 - Minimum for group A, and so on:


You can put in as many box plots as Sheets will allow, but you should keep the difference data, which is what you will plot, all together to make it easier on yourself.

Highlight the range of data Choose Insert -> Chart, then under Chart Type choose Stacked bar chart (Stacked column will give you a vertical box plot, if you like). Change the Stacking to "Standard" and select "Switch rows/columns". If you have labels for different plots in the first row, select "Use row 1 as labels".



Then click on CUSTOMIZE and choose Series. Here is where you will use the error bar and colour magic to make this thing look a bit more like a box plot.

The first box will be 0 to the minimum filled in. Choose "no colour" to make it disappear.



The second box, Q1, should be coloured a really pale colour. I use pale yellow. Select Error bars, make sure the Type is Percentage, and set the Value to 100. This will give you a whisker that goes all the way to the minimum value on the left (and Q1 + min on the right, unfortunately.)











You can leave the next two boxes (Median and Q3) as they are, or you can play around with colour choices. Keep them different colours so you can tell the difference between the 2nd and 3rd quarters, and I'd avoid choosing colours that are too dark because that extra whisker stands out too much.




Lastly, set the last box Maximum to the same pale colour you used for Q1. Select Error bar, keep the Type as Percentage, and set Value to 0. Sadly, if you choose 100 you'll get a right-hand error bar that goes beyond the maximum, which I think would be too confusing.








Note: this would be even better in Excel, which allows you to choose left or right error bars.

Next, you can turn the legend off, set the minimum value to be something a bit more in line with your data, and add some extra vertical gridlines if you like.

So there you go: quasi-box plots in Sheets. Let me know if you find this useful or have any suggestions for making it even better.




(This is what it looks like if you put 100% error bars in the Maximum box. Not worth the confusion, in my opinion.)

Upcoming (Really Soon!): Google Camp 6.0

Google Camp promotional poster

TDSB Google Camp 6.0 is next Saturday. It's sold out, naturally, but if you are lucky enough to go, I'll be presenting three sessions in room 218.

Session 1 is an updated and expanded version of Taking Math Digital with Desmos, Geogebra, and Equatio. Come explore tools that can make investigation in math, science, and STEM easy and fun. The Desmos graphing calculator, in particular the activity builder and activities such as Card Sort, Polygraph, and Marbleslides, is a valuable tool that makes helping students explore math concepts easy and interactive. Geogebra is a GSuite and user-friendly version of Geometer's Sketchpad. We will also talk about the updates to the Chrome extension EquatIO, helps write your math using predictive text, handwriting, and speech input, not to mention integration across all GSuite platforms.

Update: John McGowan, the creator of EquatIO, will be doing a Global Math webinar this coming Tuesday to talk about Digital Math Flow with EquatIO, Desmos, and Google. How timely!

In session 2, I will be giving an updated version of Flipping the Learning. This session will show you what a flipped lesson looks like, and how I am currently integrating flipped lessons into my math and physics classes. We will discuss the pros and cons, how it can be used for differentiated learning, and how to increase buy-in. In addition, we will discuss the technical aspects of flipping, specifically the specialized flipping platform EDpuzzle (but you can keep it as simple as YouTube and Google Forms). If you watch the video ahead of time, you will get the opportunity to delve deeper into some of the nifty features of EdPuzzle and have your first curated video ready for Monday's class!

In session 4, I'll be presenting How Random! Infinite Possibilities Using Sheets, which will talk about how to make the randomized practice sheets that are my pride and joy.  Sheets is useful for so much more than just accounting and graphs! Learn how the random number functions can be used to automagically create vocabulary lists, math problems, matching exercises, and yes, graphs... the possibilities are quite literally endless. Want to create a random question of the day? Sheets! Want the answer key, too? Sheets! Even better, you can link them to other GSuite products such as Docs, Slides, or Drawings to make collaboration easy. Sample templates will be provided so you can have a finished product ready to go for Monday's class.

It'll be a busy day, with lots of great workshops to choose from. If you can't make it to one of mine, I'll put links to the resources.

Hope to see you there!

OAPT Conference overview and sundry nifty physics things I've been working on



I'm writing this on the train back from the OAPT conference hosted at the University of Western Ontario, and it was, of course, amazing. I have so many thoughts and new great ideas to put into practice. Some quick takeaways: 
  • thinking about using improv techniques in class to overcome my (and students') implicit bias, especially "Yes, and?"
  • "We use mathematics to help us make the physics more precise."
  • "Just because I don't have a 'math brain' doesn't mean I don't have something useful to contribute."
  • "You're not part of a group, you're part of a team."
  • Yes, the students do really need to draw a picture
  • Why haven't we been using the rotunda at Jarvis to make super-long pendula?
Also, this happened:
I think I'm going to have to wait until June to do the write-up justice.  I will share my presentation on Tweaking the Traditional Lab below; a link to various files and resources is posted in the resources section of this blog.


(Incidentally, one of the things I always like to mention when I'm introducing myself at presentations is how amazing the PD is on Twitter. The chart on the first slide is a perfect example. Elizabeth Houwen (a math teacher, incidentally) posted it last June, and I thought it would be a great way to get the students to practice unit conversions as well as estimation, and we also got a nice little lab out of it and an anchor chart so they have "reasonable" speeds to compare their answers to. All from one small tweet!)

***

I've been busy converting my drill sheets practice sheets, which I mentioned in my last post) into Google sheets, as well as creating new ones. I'm fairly proud of the chemical nomenclature one (in part because I just found out how to write superscript and subscript numbers in Sheets, so the clunky ^3 _4 notation is mostly gone), but I really want to share the electromagnetic right-hand rules ones.

I made these using the =image() function, which allows you to put an image directly into a cell (and not just overlay the image on top). Unfortunately, you can't use the shared url of images on your Google drive (which is odd and annoying).

I'll probably refine the mixed version so that it's a little more clear what you need to find in each question; I'm not sure a student would recognize immediately that they need to find the direction of the action of the magnet for 1 and the location of the north pole for 6.

You can find these and a lot more randomized practice sheets at my course website; click on the practice sheets link under Resources.

Incidentally, sometime between last December and April, Google changed the formatting of "publish to pdf" for Sheets so that it's landscape instead of portrait. There doesn't seem to be a way to modify this, and it's really mucked up my formatting. Everything is spread over two pages, and don't get me started about what it did to my spectroscopy sheets.

Please let me know if you find these useful!

Need spectrography and HR diagram drill sheets? Here you go!

In ongoing PD news, you can still register for the Ditch That Textbook Digital Summit; 9 videos, 9 days. The videos will be available until Dec. 31. Follow the fun at #ditchsummit on Twitter.

I'm still trying to put together my blogs for the fall PD I've been doing, but for now I wanted to share a few things I'm really excited that I figured out how to do.

Inspired by Robert Prior many years ago, I started coding a lot of Excel spreadsheets as randomized drill sheets on many topics. My goal for this year is to get most of them up as Google Sheets so I can publish them to the web and students can go straight to my website to print out an infinite number of sheets.

Anyway, I've also been working on adding new, richer sheets to my catalogue. In particular, I was very jazzed last year when I figured out how to get a spreadsheet to draw spectrographs (hint: error bars). And last night I spent far too long working on how to get a Hertzsprung-Russel diagram (yay for the Bubble chart, boo for the fact that the labels are arbitrarily hidden when you go to a larger font).

Behold, I give you my Spectrograph and HR diagram drills for the grade 9 space unit (and Earth and Space science, too).

I'm still working on the HR diagram answers; I have to figure out how best to get it to choose whether it's on the main sequence or not. Also, I think I need more white dwarf stars, because that area is looking pretty sparse.

However:

 If you'd like to see my other drill sheets, head on over to the drill sheet section of my course webpage. It's very much a work in progress. I have a lot more sheets than I've listed there.
