HS Geometry Professional Community Online - Join now!

For the first time, OCTM is offering educators all over Ohio the chance to participate in a professional learning community online, specifically for HS Geometry (this is a pilot... other courses and grades will hopefully follow!).  The facilitators are Jacqui Lehmkuhl (teacher at Troy HS, and OCTM Vice President for Secondary) and Jenny Walls (teacher at Firestone HS in Akron, and past president of GAMES).  The platform for this work is Google Classroom, and participants can simply follow or take part in discussions and sharing resources.  10 contact hours (1 CEU) can be earned.  We encourage you to join!  Participants need to be members of OCTM (click here to join OCTM online).  See the flier here for more details.

OCTM Membership and Engagement

What opportunities do you and your mathematics colleagues have to participate in informed, collaborative professional growth?  If you are an administrator, do your teachers participate in OCTM?  You can help colleagues become part of this organization comprised of a strong network of 3,000+ educators in Ohio.
  • Information you can share about OCTM: Share this video in which 5 OCTM members talk about their reasons for being involved, and share this file that includes 10 specific ways to be involved in OCTM all year long.  Visit the links to the left for more details.

Additional ways for you to be involved:

  • We invite you to respond to this brief survey that will help OCTM leaders to provide opportunities that support professional growth.
  • On Twitter, watch for tweets from OCTM members sharing their professional learning and growth at @ohioctm and #octmconnects .
See a list here of all those who have invited at least one new member to become part of OCTM since Fall 2018.  This is how we grow!


The OCTM Journal is equitably and ethically connecting people across the country and beyond

Julie Nurnberger-Haag of Kent State University shared a story with Todd Edwards, the editor of our Ohio Journal of School Mathematics, about how the Journal is helping mathematics educators across the country to connect and share ideas.  In 2018, the OJSM included an article of Julie's in which she shared guidelines and templates for selecting, using, and even creating children's books about geometric shapes.  A librarian in Wisconsin contacted Julie to let her know that the article had been very helpful to her, and this helped Julie to connect with additional librarians.  

Julie notes that the online, open-source format of the OJSM allows for equitable access to information that is useful to educators.  Further, since our authors maintain their copyrights, they are able to ethically share their own work as they choose.

Thanks very much to Julie for sharing this experience with us, and thanks to all of our OJSM authors, reviewers, and our editor Todd Edwards!  Read Julie's complete comments on our OJSM page here.


OCTM's Last Surviving Charter Member

Luther Shetler, Mathematics Professor Emeritus at Bluffton College/University, was the last surviving charter member of OCTM. During the banquet at the 2019 conference, several OCTM members wrote a brief note to Dr. Shetler to thank him for his role in the creation of our organization.  Duane Bollenbacher (OCTM Historian) was able to visit Dr. Shetler to share our message of gratitude.  Many commented on the impact Dr. Shetler's "Mathematics of Bubbles" presentations had made on them.  We are saddened that Dr. Shetler passed away on December 15, 2018.  (You can read his obituary for further details about his life.)  When Duane shared the news of Dr. Shetler's passing, he mentioned how appreciative Dr. Shetler was of the note from OCTM.

As an organization, we are incredibly grateful for the work of those who came before us.  We truly stand on the shoulders of giants. 

In honor of those who have come before, we are beginning a new series called "They Made a Difference" to highlight educators who have made a difference for YOU in mathematics.  To submit a brief remembrance for this series, write to Jodie Bailey (jodie.bailey@ohioctm.org).  Find this series and other OCTM history at this page on our site.
