Part of placing value on the process of learning means giving students multiple opportunities to demonstrate understanding. Reassessments are an inevitable part of the process. For many teachers, this presents a logistical problem. To help streamline the entire process, I would like to share a simple strategy that anyone can replicate in a short amount of time.

This introductory lesson uses a crosscutting concept, structure and function, as a means to model pre-conceptions of a voltaic cell. A phenomena is used to pique curiosity and engage students as they progress through the unit.

Now that the 2018 administration of the AP Chemistry Exam is in the books, all of us AP Chemistry teachers now have an opportunity to reflect on the year as we turn our attention toward preparing for the fall.

Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them. I am a huge fan of finding chemistry in the real world and using it as an integral part of my instruction; and as we were experimenting, I was reminded of a rather fun activity I had done on Valentine’s Day with my AP students.

Titrating this year for me has an added complication. The complication is that half of the science department has to be completely packed up and out of our rooms, including chemicals and equipment, before school ends. Half of the department is going to be completely remodeled (my half of course). Teaching must still go on in the middle of the madness.

If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?

I have blogged about Argument Driven Inquiry (ADI) previously. It has been a popular topic on ChemEd X lately. During my limited experience, I have found the process to be a bit drawn out but extremely helpful and beneficial. The time spent has been well worth it.

Based on some interactions here on ChemEd X and Twitter, I have been looking for ways to have students generate more questions, ideas, and investigation methods. (See a list of relevant links below.) Some of this is inspired by Argument Driven Inquiry, while some of it is simply my own quest to move further away from being the sole source of information in the class. In this blog post, I would like to talk about how I addressed gas laws using Atomsmith Classroom Online as an investigative tool in place of lab work I did previously using the Vernier gas pressure sensor.

Recently, my district made a commitment to helping its teachers reflect and rethink their grading and assessment practices. One of the phrases I kept hearing throughout our staff professional development sessions was authentic assessment. I understood (and agreed with) the basic premise—create more opportunities for students to perform tasks that demonstrate meaningful application of essential knowledge and skills. Doing so involves going beyond, or even potentially replacing, traditional summative assessments at the end of each unit.
