 16 pages, stapled at the corner, short essay answers. I organized a team of 100 graduate students, faculty, postdocs to help me grade that exam. I compensated them with pizza on a Saturday. It was a logistical nightmare. And that event inspired me to invent a new way to grade, which we call Crowdmark. Crowdmark is an online collaborative grading platform that allows teachers like me and teachers in K-12 to evaluate student work more effectively than ever before. Instead of carrying a backpack filled with paper, teachers can carry their laptop and have access to the digital portfolio of all of the work that their students have ever done. Let's compare. Well, here's an example. This is Dan Weaver. He's a graduate student from the University of Toronto at a high Arctic Research Station, grading a physics exam that was written the day before using Crowdmark. So you can grade anywhere. You don't have to come to the paper. We bring the paper to the grader. Let's compare the traditional paper-based red pen on margin workflow with Crowdmark. Now, if you were to find Jessica's exam in that big pile of paper, page four, you're going to spend a long time searching. But with Crowdmark, you can use search tools and find that page very, very quickly. We organize the work in such a way that the rows correspond to students, the tiles correspond to evaluations, and you can evaluate question by question by question in a very rapid manner. So when we ask teachers, what do they feel bad about in their job? Many teachers report that grading is a key element of the feedback that they give to their students, but they just don't have time to provide that kind of feedback. Now with Crowdmark, you can provide feedback with free form annotations like pen marks, as well as leave formative assessment comments, including mathematical notation, chemical notation, hyperlinks that point to online textbooks and other resources. And those students can then click those links to learn faster. Returning exams right now is a real pain. You sometimes lose an entire hour of instruction handing back the paper. But with Crowdmark, you click one button, and all of the students receive back their exams together with the associated scores and commentary instantly, which saves instructional time. Now exams sometimes require regrading. So universities and colleges are storing exams in vaults that have to be alphabetized, put inside of banker's boxes, and stored inside of exams vaults. But with Crowdmark, you can access all of those resources nearly instantly using web search. Maybe you're still not convinced. So let's consider what teachers do today. Teachers spend time grading, and if you look at this as a global market, we are currently investing as an education system more than $60 billion per year in salaried time while teachers perform evaluations of student work. In our experiment so far, in all forms of engineering, Latin, history, chemistry, physics, different branches of mathematics, we have a robust result that Crowdmark, the online collaborative workflow, cuts grading time by 50%. As an example, we returned 12,000 pages of a calculus exam written by 931 students with formative assessment comments, including mathematical notation, in 22 hours. We capture data on a question-by-question basis, and we can correlate that across multi-section courses, giving new insights into student performance that aren't obtained when you look merely at total scores. I have a fantastic team. We have two PhDs on our team, including Dr. Lisa Neal, and I'm advised by a fantastic Board of Advisors, please look at crowdmark.com to see more information about our team. What's our business model? It's a two-phased approach. The first approach is we sell this as a productivity tool to educational institutions so that they can improve the feedback that they give back to their students, and it's priced per FCE or priced per student. Over time, Crowdmark facilitates the creation of a grading as a service labor market, and we are developing data streams to provide human capacity to education institutions that don't have enough of it to perform evaluations at scale. Some feedback from one of our users. There's simply no comparison between red pen on paper assessment and the online workflow. It's simply the future of marking. So I invite educators worldwide to send me an email, james at crowdmark.com, and I'll set you up with a pilot so that you can see the benefits yourself. I also invite investors to come talk to me, and I can help your limited partners make a lot of money. All right. All right, thank you.
