One of my goals this year is to be much more intentional with the demonstrations I use. This includes thinking carefully about the conceptual understanding I [...]

Developing better internal schema in chemistry students

Pre-warning. This is a bit of a long read and gets a bit heavy. If you want to skip to the final summary, scroll down! Disclaimer: A lot of this article is based on the work of Talanquer (2015). Barely any of it is my own so please do take a look at his article [...]

As stated in the article, threshold concepts are often troublesome for learners. However, they have the potential to be so transformative in their understanding of a discipline that they are worth the pain. Indeed, once [...]

There are certain concepts in chemistry that students must understand if there are to develop an expertise in the discipline.  We can call these “threshold concepts”. These threshold concepts should be considered as a portal to further understanding and, according to Meyer and Land (2003), should be: Transformative - once understood, it should cause a [...]
