Mark 740 tests in 60 seconds

The Challenge

How can you mark 740 assignments in less than a minute?  Can you imagine the MIS system that would be required for this and the many thousands of dollars required? To top it all, you have no budget for this and no server hardware.

Surprisingly, you can actually do it using completely free software!  You will need a little programming expertise and a plan to break up the onslaught of data you are about to receive!

Requirements  

Here's what you will need to pull it off:
  • Google Apps - So long as Google Apps are not blocked, then that should be enough.
  • Internet connection - Unless you have amazing WIFI I would not recommend doing this in the main hall. In our case students were in classrooms, which in most schools puts much less strain on the Internet.  If this is likely to be a problem, then you can still achieve rapid results, but it will be limited by the number of students you can get on the Internet at once.  It's also perfectly feasible to use 3G, if your students are on mobile phones. 
  • A device each child can have access to - Students can share by taking a turn each, but it will be slower. 

How it was done

1. Split up your entries

It is important that you limit each Spreadsheet to about 200 entries for high speed marking.  You could split it up by year group or school house.   These can be put back together again later, but at an individual teacher level you are likely to only need to see a small number of the entries.

2. Create a Form

Firstly you need to create a Google Form with either multiple choice questions or one word answers. Web of Notes has a nice guide for this.


3. Mark it with Flubaroo (Optional)

If you would like to send an email to the student and have the whole cohort marked, then Flubaroo is a great way to do this. http://www.flubaroo.com/flubaroo-user-guide  If you are a classroom teacher marking your own class, then you can stop here, but for the speed we need you will need a faster method.


4. Importing the data


On row 3 use an importrange command. 
(Row 1 will be used for titles and row 2 for Awesome Table commands.)
=importrange("1FCA2NN8RUXIQVtX-3DZIBWDC3COnaMO_z5W91SsyCcc","DP1!A2:W200")
You need to import all the information that you are going to process. See the video for a full breakdown of the command.






5. Marking the Data

There are two ways to do it. Either you can fill the form out yourself as the first entrant or you can hard code the answers in.  Hard coding is slightly faster, but your code will be reusable if you put the answers in first and it works with Flubaroo.

The first method works like this:
I used an if(H$3=H3,1,0)


You use the if formula and if the answer is correct you give it 1. If you would like to weight answers you can change the numbers accordingly.

H3 = Being the cell where the answer is.
The $ means that when you copy and paste it won't move down.


Optional: To make the spreadsheet look more effective I added the isblank command, but it does not have to be used:
=if(isblank(H3),"",if(H$3=H3,1,0))

You can also use conditional formatting to see at a glance how students are doing.


6. Creating a front end for the sheet

I used Google Sites to make a Website that broke down the various checkpoints and houses.
One very useful feature of Google Sites is that you can use Insert -> Subpage listing.

For the large Scale study we had 4 checkpoints split across 4 houses. Making 16 individual quizzes in total.


I created a front page and then on each sub-page I copied and pasted the questions. This enables you to display more columns in the page itself.

7. Awesome Table

To display the actual results for individual teachers I used a gadget called Awesome Table. (Which is also the reason I used Google Sites.)  This is why we needed to leave rows 2 blank.  For each column decide how Awesome Table should handle it:

  • CategoryFilter
  • CategoryFilter - Hidden
  • NoFilter 
  • Hidden

The CategoryFilter enables you to choose which columns teachers can see and what they can filter on.


Number based columns appear as a slider and text based appear as a drop down. (You can select multiple keywords)


8. Roll Out the Forms

Once everything is in place you will be able to roll out your forms, teachers can see the data that they need for their groups, heads of year can see their whole year at a glance and senior management can quickly evaluate all of the data.   

To provide a whole school view, you will either need to use several import range commands for a live Spreadsheet view or copy and paste once data collection is finished.

By using this method mentors had immediate access to filtered data via the dashboard on their students and up the ranks, leaders could target students who were likely to need more help.

The Result

I expected it take up to 5 minutes for the data to come rolling in, but I found that data was being delivered significantly faster and in most cases the slowest part of the process was the time taken to load Awesome table.  Raw results were coming in less than a second and teachers had access to those results in under 60 seconds.

Piloting it in your school

My advice is to have a go with something low stakes. You can start with something as simple as a quiz that you might do in form time. (Homeroom time).  Test if your Internet can handle it and if so you have an amazing opportunity to collect and analyse data in near to real time.  

Future enhancements

1. The viewer worked very well for Mac or PC based teachers, but did not work quite as well for iPads.  We are looking into how we can address is this.
2. Live charts - Live charts are a possibility, because we found out that each tab is a separate task in Google Sheets.

With thanks to the following people

Using Versal To Flip The Learning

I looked at quite a few platforms to host my new course. Tackk is very simple and quick to use, but I soon hit the limits when I put my Scratch course together. Udemy and other online offerings are very much video focused and although I wanted to include video I didn't want it to be the main teaching medium.

So I opted for Versal. Firstly let me stress Versal isn't really designed with coding courses in mind. It's a general purpose online teaching tool, but it has the flexibility built in to enable me to create the materials that I wanted.  However there are some features that make Versal a great choice for this kind of course.

Firstly, you have all the standard tools that you expect to see in an editor such as the ability to insert videos, a good range of interactive quizzes and integration with Google Drive.

The most useful built into Versal is the Markdown editor, which conveniently has a Code option. This is wonderful for including little snippets of code.  However it doesn't handle indentation too well, which is important for Python.

However to include longer pieces of code I turned to Pastebin.com  this enabled me to include code quickly and also in a format that students could easily copy and paste materials without annoyances such as numbers and indentation problems.  There are some limitations, in an embedded window you can only get about 30 lines of code. If you want to share a longer code sample, you are better off including a link.

Finally I included the code on GitHub. Useful enough to have a quick to download zip file, but I feel it's good for students to start using the industry standard tools as soon as possible: https://github.com/jamesabela/PyGameCourse

Christmas Gift for everyone: Python & Pygame Course

For the past week I've been making my way around Versal and after quite a lot of work. I've managed to publish my first course. Please take a look it's at: https://versal.com/c/clzqsx/python-pygame 

It has been an experience to see just how expert many tutorials are. Most appear to be aimed at the truly dedicated! I can't imagine many children wanting to put in more than 100 lines before they even get their first game!

One aspect of the coding process that has been very helpful is Pycharm, it's debugging is far superior to the default client and I'd highly recommend getting it installed. The EDU edition seems to have a great feature set and taken away some of the more complex features.

Feel free to have a go and please let me know what you think! The code has all been tested in Python 3 & Pygame.

Quiz Tools - The Ultimate Showdown


This week was a revision week before my year 10's next big assessment. So I decided to run a little competition. The students could choose any quiz app they pleased and then the following lesson we'd play the quizzes.

Round 1
Quizlet was knocked out the competition straight away, because none of the year 10s wanted to develop quizzes for that platform and neither did any students choose Socrative. So they didn't make it to the final!

Round 2
The two finalists were Quizizz and Kahoot Students enjoyed creating questions for both platforms and the process was pretty similar.

The Grand Finale
I used a Single Google Sheet to coordinate the quizzes. Each student gave me an url to direct the quiz. I then used a random name picker to choose the quizzes.







Let Battle Commence! 

Both platforms feel like a quiz show with countdowns and music.

Class Game Vs individual

The first key difference is that in Quizizz students play through all the questions when they choose to start the game. This enables students to do the exercise when they have finished another task or it can even be set for homework.  Whilst on Quizizz they were highly focussed on their screens but they were not so directly competing with each other.

In Kahoot the whole class plays together, which adds to the sense of community but means everybody has to play the same quiz at exactly the same time!

Question displayed on Main Screen Vs at Your device

Quizizz also displays the questions on the students device, so not everybody has to see the projector, which is a real advantage in rooms with poor visibility.

Logins
We had no difficulties at any point logging into Kahoot and this weekend I had over 80 players at once playing it. With Quizizz we did have one or two small login problems, but all were fixed with the judicious use of the refresh button.

Who won?




The students narrowly gave the win to Kahoot! They acknowledged the fact that Quizizz enables quizzes to be given out as homework and they enjoyed using both.  So it was a noble contender that we hope goes from strength to strength!

Cameron must be following my lesson plans!

I'm In year 7IT we are teaching our students the ethics of using Photoshop.  Firstly by showing them the tools and then asking the bigger question as to what is an ethical use of Photoshop? 

A good example of somebody who is manipulated on a regular basis is David Cameron. Some parts of the media support him and naturally enough choose complimentary photos. Others are not so happy with his performance and are quick to show him red-faced. The lesson was a great success and the students soon turned to making themselves into heroes and villains. Being Halloween, it was doubly fun! 


Now my next lesson is to mix a foreground and background image.  So imagine my surprise this morning when I see this.


Is Mr Cameron reading my lesson plans?
So the only question left is, has Mr Cameron's team crossed an ethical line with this?  Please comment we'd love to hear from you!

Setting up a great Python Coding Environment

Due to haze days we've had a bit of time to sort out a very nagging issue for me. Ensuring my students have a great coding experience!  Easy enough if you are using a Raspberry Pi, which is setup very nicely to code out of the box with a new OS and tools an SD Card away, but for real computers this can be a pain in the neck!

My first requirement was a version of Python that works well with Pygame and something we can replicate across a number of PCs.  We use Macs, so after much playing around we figured that Bootcamp was our best option to deliver Python 3.4.3 with Pygame. (At the moment I can't find a 3.5.0 version)   We tried numerous times to get it working natively on Mac and failed miserably. Best I could do was get version 2.7.1, but then we discovered it relies on quite a lot of emulation anyway, so seemed like a waste of time.  (Please put comments in, if you have had more success than me.)

Linux is actually easy enough to install, but Windows is already installed and the students are largely familiar with it.

The Method

PLEASE ONLY DO THIS IF YOU ARE A CONFIDENT COMPUTER ADMINISTRATOR.
DO NOT TRY WITHOUT PARENTAL / EMPLOYER PERMISSION.

So after looking around most of the net, we found an excellent site: http://programarcadegames.com/  So here are the instructions:

  1. Remove all previous versions of Python on your PC. (We had quite a few)
  2. Run the Python installer downloaded from:
    ProgramArcadeGames.com/python-3.4.3.msi
  3. Run the Pygame installer downloaded from:
    ProgramArcadeGames.com/pygame-1.9.2a0.win32-py3.4.msi

Next we found an excellent editor called Pycharm Edu, which has a number of extra teaching features which I hope to start using in the near future: https://www.jetbrains.com/pycharm-edu/  Just download and follow the instructions.

One point to note, when you make a new project you have to choose interpreter 3.4.3. Pycharm automatically adds 3.5.0.

Minecraft Mega Structures

My Little Minecraft Pi project!

This is my Raspberry Pi project.  It's great to use Minecraft to create buildings, but the power of doing it programmatically is that you can create whole streets and towns.  This basic Python code will produce a street of skyscrapers.  

There's a lot of potential here and I am sure it would make the basis for some great lessons. What's great fun is as soon as you show people the idea people run with it & think of all sorts of refinements.

Here's the Python code, I hope it all makes sense. 

# Setup Minecraft library
from mcpi import minecraft
mc = minecraft.Minecraft.create()
#Get player position
x, y, z = mc.player.getPos()
#Terraforming - Create air
mc.setBlocks(x-30, y, z-30, x+500, y+39, z+40, 0)
#Make a grassy area
mc.setBlocks(x-30, y-1, z-30, x+500, y-2, z+40, 2)
#Loop to create 6 buildings
for builder in range (0,5):
    # Create stone block
    mc.setBlocks(x+1, y-1, z+1, x+11, y+40, z+11, 1)
    # Make it hollow
    mc.setBlocks(x+2, y, z+2, x+10, y+39, z+10, 0)
    #Create a series of windows
    for glwin in range (0,4):
        mc.setBlocks(x+2, y+(glwin*10), z+1, x+2, y+(glwin*10+3), z+1, 20)
        mc.setBlocks(x+6, y+(glwin*10), z+1, x+6, y+(glwin*10+3), z+1, 20)
        mc.setBlocks(x+8, y+(glwin*10), z+1, x+8, y+(glwin*10+3), z+1, 20)
        mc.setBlocks(x+2, y+(glwin*10), z+11, x+3, y+(glwin*10+3), z+11, 20)
        mc.setBlocks(x+6, y+(glwin*10), z+11, x+7, y+(glwin*10+3), z+11, 20)
        mc.setBlocks(x+8, y+(glwin*10), z+11, x+9, y+(glwin*10+3), z+11, 20)
    #Create door to see inside
    mc.setBlock(x+2, y, z+1, 71)
    mc.setBlock(x+2, y+1, z+1, 71)
    x+=25
