December 2018 Xchange

Dear ChemEd X Community,

2019 is almost here and I am making plans to attend spring and summer conferences. I am especially excited to attend ChemEd at North Central College in Naperville, IL! The conference runs July 21-25, 2019. I encourage you to . The organizers are accepting through February 2, 2019. I look forward to seeing old friends and meeting new ones in Naperville!

Our December issue of the Xchange highlights some of the contributions we have published over the past month. I hope you will take a moment to check in and see what you may have missed.

This chemical mystery is very easy to perform. Figuring out how this trick is done is also easy...if you know your chemistry! 


In an effort to implement the science and engineering practices of the NGSS, Stephanie O'Brien tried to introduce argumentation as a practice into her chemistry courses. She shares some growing pains and things she has learned through the process. 


In an effort to align an old VSEPR lesson to NGSS, the author told her students that they were going to look at the data available from the real molecules on the pHET simulation they were using and specifically look for patterns. Finding patterns is a cross-cutting concept; one of the three dimensions of NGSS.


When people, including educators, are in the majority they do not always understand the perspective and experience of those in the minority. The author encourages all teachers, in any content area, to make their classrooms safe for students to learn and take academic risks.
