However, this type of journalism is often propaganda like in delivery, focuses on the violence (and sometimes glamorises it), focuses on the suffering of one side and the actions of elites,...

Conceptual understanding of epistemological issues in chemistry As discussed in this post, epistemological components make up part of the complex cognitive processes that help students to understand threshold concepts. The epistemological components are to do with how arguments and explanations are built in a discipline. In chemistry, this is mainly to do with the use... Continue Reading →

Read this article if....you are a concept geek who just loves...well...concepts... I recently wrote about threshold concepts in this post. 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... Continue Reading →

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...

Some of the terminology that we use in chemistry can be extremely confusing for students! One such example is when we talk about bonding. A bond is the name given when electrostatic forces of attraction between oppositely charged particles are balanced with the kinetic energy that would cause them to move away from each other...

As Stern, Ferraro and Mohnkern point out in “Tools for Teaching Conceptual Understanding: Designing Lessons and Assessments for Deep Learning”, the biggest pitfall that teachers face when introducing a new concept is that they are tempted to introduce it as a fact. This means it becomes a definition to be memorised, rather than a concept... Continue Reading →
