January 7 & 8, 11:00 am - Noon MST

Teaching Calculus Online with Derivita & SpotCheck. Prizes for ALL live session attendees! Join for a chance to win prizes including Derivita T-Shirts, Picnic Blankets, or Amazon Gift Cards!

Moving from the in-person classroom to Zoom to teach hybrid or fully online math classes has presented a unique set of challenges - especially when teaching complex concepts in Calculus. In the classroom, faculty are able to do quick checks to evaluate how well their students are comprehending key concepts and can easily determine knowledge gaps. In a remote environment - it’s a bit trickier - but even more critically important to quickly assess how well students are grasping the material. In this session, Devlin Daley, will provide a sneak peek at Derivita’s newest features including Spotcheck, a synchronous, online tool for increasing participation and assessing students in real-time. We will also explore how to use Derivita to deliver the entire Calculus series for in-person, hybrid, or fully online courses. Learn more at: www.derivita.com/calculus.

Created by the cofounder of Canvas, Devlin Daley, Derivita is a first of its kind math platform with a proprietary computer algebra system. Built for educators, Derivita provides an immense library of questions from Algebra to Calculus III. Homework assignments, quizzes, and exams can be created in minutes and instantly added to your course without ever leaving your LMS. Student submissions are entirely auto-graded and students are provided with immediate, meaningful feedback. Derivita can be used with any textbook and seamlessly integrates with any LMS. RSVP for this session at info@derivita.com.
