The November 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. 


Active learning techniques can be used to increase encoding and consolidation for long-term memory formation, but using active learning techniques with novice learners may require scaffolding or direct guidance so that our students can actually learn without becoming overly frustrated.


The flipped classroom of today looks vastly different from its initial form. Originally, class time was primarily used to complete homework assignments; however, more effective active learning practices tend to dominate class time in modern applications of the model.


The author shares how he and his colleagues focused on improving their coverage of the practice of planning and carrying out investigations.


The Devil's Milkshake is a simple, yet interesting chemistry experiment that can be used to support a variety of content including alkali metals, alkaline earth metals, chemical change, energy, pH, solutions and titration. 


Standards based grading (SBG) is a method of assessment that is gaining in popularity.  There is ample research to suggest that students who participate in SBG do just as well or even better than those students in traditional classrooms.


In honor of the International Year of the Periodic Table - Originally published October 2018.

 This five puzzle mystery covers properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.


The author offers a microscale procedure to precipitate sodium chloride from two group one salts.


Millions of years of evolution has endowed brown and black bears with the metabolic capacity to starve themselves for a long period of time and still survive. Bears are chemist extraordinaires and their hibernation chemistry overall is arguably without equal in the mammalian world.


The understanding of how measurement works is crucial for lab skills and for understanding significant figures. Some think measurement should be an easy topic for students to learn; but in reality, teachers spend countless hours teaching and reteaching a seemingly simple skill. 


Want to heat up a department meeting? Just say you want all courses to have an on-line option.
