Hurdles and Bottlenecks (in ionic bonding)

I wanted to identify threshold concepts, which can be described as “portals” to greater understanding. I’ve also seen them described as “bottlenecks”, and I think this is a helpful description. It’s a concept that holds you up, and prevents you from developing a deeper understanding.

I compiled a list of tricky concepts using a variety of misconception sources, but I would describe most of these as “hurdles” rather than bottlenecks. Hurdles need to be cleared, but they don’t hold you up in the same way that bottlenecks do.

Harkness – the fad that’s worth the fuss

Harkness may not be the newest idea in the teaching world, but I feel it is one that has been unfairly overlooked.

It’s an idea taken from Edward Harkness, an early 20th century philanthropist and educational reformer, and the concept is based on Harkness’ own education. He felt that the traditional approach of sitting in rows whilst the teacher taught from the front created a hierarchy which did not support those who had less confidence or needed more support. Harkness came to favour a ‘conference’ pedagogy where students engaged in conversation on a topic they had prepared before coming to lesson, rather than answering specific, narrow questions directed at the few from the front. Harkness ‘gifted’ this idea to Phillips Exeter Academy in the United States, where they developed it and adapted it into a workable educational approach, and now use it as their sole teaching method.

Growth Mindset in PE

Sitting in the growth mindset training at the beginning of term, I realised that this ‘new’ initiative had been taking place in PE for many years; we just call it “coaching”.

In each lesson, we give pupils the opportunity to show resilience, to learn something completely new and even to fail. Our pupils receive instant feedback that they can act upon straight away.

How (and why) to read Scientific Research Papers – a student’s perspective

I distinctly remember my first meeting (about atmospheric chemistry research) and having no idea what was being discussed around me. Up until this point I had no knowledge of CFCs and felt completely out of my depth around those who had read and understood the paper.

After being surrounded by specialist language for an hour, I still couldn’t blag my way through questioning so decided to learn to read a paper in a way I would find easy.
