September 2019 Xchange

The September 2019 Xchange highlights some of the contributions that have been published on ChemEd X over the past month. We hope you will take a moment to check in and see what you may have missed. 

“Education is not the learning of facts, but the training of the mind to think.” – Albert Einstein

     

Tom Kuntzleman shares some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals! 

 

     

Tom Kuntleman has followed up on his "Marvelous Interactions between Metallic Money and Magnets" post (highlighted above) with some further investigating in the lab to come up with some simple chemical tests that can be done on coins as well. You don't want to miss this one. 

     

On August 1st, College Board released its new AP Classroom platform. Melissa Hemlings shares her reflections on how she has previously taught the course and changes she plans to make in light of AP Classroom.

     

Clarissa Sorensen-Unruh recently presented a workshop around the ideas of critical pedagogy and STEM, and particularly on how teachers use these ideas in a practical way in the classroom. 

     

Starting the school year by using an engineering activity helps the Melissa Hemling  create a culture of group work in her classroom. This activity helps students get comfortable making their own claims based on evidence collected from the labs they have helped design and by using scientific reasoning.

     

Many teachers assess engagement with video lectures by inspecting students’ notes at the start of class. However, note-taking doesn’t necessarily prove the comprehension of the material.

What value does spending time explaining our syllabus in class provide? How much time should we invest in going over the syllabus with our students? Thoughts on talking about the syllabus during the first class meeting?

     

In order for students to be fluent enough with the cross-cutting concepts and core ideas to use them to support their arguments, teachers need a way to help students become familiar with them.

     
     

In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Iodine is the fifth in this series of elements to be discussed as part of the Element of the Month program. 

     

Erica Posthuma had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. She has outlined the resources she used and how she pulled the course curriculum together.

 

     

The September 2019 issue of the Journal of Chemical Education is now available online to subscribers. Erica Jacobsen shares highlights from this issue of the Journal of Chemical Education of special interest to our ChemEd X community.
