Build a Boat Collaboration

Kristin Gregory | Sat, 08/08/2020 - 18:05

As many teachers are preparing to teach online, we are revisiting posts from the ChemEd X archives like this one that might be of help. The original Build a Boat challenge was used to help create a classroom culture of teamwork and growth mindset. The author has updated the Build a Boat activity by providing a modified slide show presentation specifically to help those teaching remotely this fall. 

Drawing Particulate Models

Ann Gardner | Wed, 05/30/2018 - 11:48

Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.

Tackling Big Ideas

Chad Husting | Fri, 09/02/2016 - 11:38

It was the empty terrible feeling in the pit of my stomach at 9:30 at night that really bothered me as I am wading through the stack of papers that I was grading. I had the students do experiments, worksheets, I lectured and there was homework. Some of the students could “do” what I thought was science. They could calculate the answer. They could balance the equation.

Opportunities For Chemistry Modeling Training

Deanna Cullen | Tue, 02/24/2015 - 18:02

The Modeling™ curriculum emphasizes modeling, collecting evidence, scientific discourse and development of conceptual understanding. All of these can be linked to AP and NGSS standards. If you are looking to make improvements in your curriculum and gain some impressive strategies, consider enrolling in a workshop this summer. There are many workshops scheduled around the country during the summer. A full curriculum and support materials are provided.

Conceptual Chemistry

Larry Dukerich | Wed, 11/19/2014 - 16:19

In a recent contribution to ChemEd X "Stoichiometry is Easy", the author states that he has "vacillated over the years between using an algorithmic method, and an inquiry-based approach to teaching stoichiometry. " I would like to suggest that there is another approach to mastering stoichiometry and that it should precede the algorithmic one: it is the conceptual approach based on a particle model to represent the species involved in chemical reactions.

Simple Activities to Integrate Particle-Level Diagrams

Erica Posthuma | Mon, 10/20/2014 - 08:34

There have been many conversations within the Chemistry Education community surrounding the revisions to the AP curriculum. Twitter has been buzzing with instructors debating how to implement the changes, conferences and workshops have participants deconstructing the data from last year’s exam, and classroom teachers are working diligently to prepare their students for this year’s test. One way the College Board has tried to shift the AP curriculum away from algorithmic problem solving and toward more meaningful conceptual understanding is through the use of particle diagrams.
