Today is a very special day – it’s the 50th anniversary of Earth Day! Since 1970, each year on April 22nd the world recognizes the earth and celebrates all of the resources it gives us. 

When thinking about Edulastic’s impact on the environment, saving paper is the first thing that comes to mind. When teachers use online assignments and assessments, they print fewer and fewer lessons, worksheets, and tests. And what we’ve seen is how this is great not only for the environment, but also for teachers’ productivity!

Online assignments save teachers time because everything is auto-graded and organized in one centralized location. No more lugging home stacks of worksheets or losing pieces of paper – all the work is online and easily accessible from any place at any time. 

Last year was the first year we decided to tally up the impact of educators using Edulastic for assignments and assessments. The results of how much paper and time was saved was astonishing, so we decided to make the Edulastic Earth Day report an annual thing and take a look at this year’s impact!

We followed this same algorithm to make our calculations this year; this means that we assume ten questions per average sheet of paper, and ten seconds per average graded question. In a nutshell, we found that since last year, our community impact has doubled! Details below. 

Check it out, and if you use Edulastic, give yourself a pat on the back for contributing to such an awesome accomplishment. 

Year-to-date Paper Savings 

How much paper have we saved this year? 

To find the answer, we did a deep dive into some Edulastic data. Specifically, we found that from April 2019 to March 2020, the entire Edulastic community has answered a whopping 745,218,267 questions. Using our algorithm of about 10 questions per page of paper, we determined that in one year the entire community has saved about 74,521,827 pieces of paper! 

74.5 million pieces of paper saved is a huge accomplishment! In fact, our community saved more paper this year than we did in the previous five years combined. Well done!

But what does this number mean and what effect does it have on our earth? We turned to the Environmental Paper Network and their online Paper Calculator tool to help us understand. Here’s what we found.

 74.5 million pieces of paper means that together we have saved: 

  • 1,490 U.S. Short Tons of wood, made from about 8,920 trees 
  • 9,500 million BTUs of energy, equivalent to 11,3000 residential refrigerators operated/year
  • 6,700,000 pounds of CO2, equivalent to 608 cars/year 
  • 7,970,000 gallons of water, equivalent to 5,750 clothes washers operated/year 
  • 439,000 pounds of solid waste, equivalent to 100,000 people generating solid waste/day 
  • 139 acres of forest from being disturbed, which is equivalent to the size of 105 football fields

The above numbers are monumental and are representative of the positive change that we can make on our planet, especially when we work together. If you’re interested in seeing the full results of this report, you can check it out here

Year-to-Date Time Savings

How much time did the collective Edulastic community save this year? 

To calculate this, we did another fun deep-dive into Edulastic data. Edulastic has auto-graded 745,218,267 questions from April 2019 to March 2020. Like last year, we used our conservative estimation of about ten seconds per question to calculate time otherwise spent grading. This means that Edulastic’s auto-grading saved teachers 124 million minutes or 236 years of grading this year alone!

236 years worth of grading is a lot of time! To put this into perspective, 236 years ago brings us to 1783, the end of the Revolutionary War. The amount of time saved grading by Edulastic in the last year is equivalent to if one teacher non-stop graded from the end of the revolutionary war to today! Crazy to think about!

Now, our final question: How much time has Edulastic’s auto-grading saved teachers since the founding of our company six years ago? 

Since Edulastic was launched in 2014, 1,452,718,279 questions have been answered. Based on the algorithm, Edulastic has saved teachers a total of 460 years of grading! Now let’s put this into perspective: 460 years ago puts us at the year 1560, right before Galileo’s birth and when Queen Mary I took reign of England. Can you even imagine sitting down to grade assessments for 460 years non-stop? 

The time saved grading has grown exponentially each year as our community of users continues to grow. We are thrilled to see how much time Edulastic has been able to give back to teachers!
