Here is a 100 word summary of a piece of research I found interesting and relevant to secondary/A level teachers. And three quick ideas to start applying tomorrow.

100 word summary of the research:

Emotional Contagion by Elaine Hatfield, John T. Cacioppo, and Richard L. Rapson argues that people automatically and unconsciously mimic others’ facial expressions, vocalisations, postures, and behaviours, leading them to experience similar emotions. The authors propose that this process helps explain how emotions spread through social groups and relationships. Emotional contagion is presented as a fundamental mechanism underlying empathy, social interaction, and group dynamics. The paper reviews evidence that emotional states can be transmitted rapidly between individuals, often outside conscious awareness, and suggests that shared emotions play an important role in shaping human behaviour and social connections.

Three quick ideas to start applying tomorrow:

1. Narrate productive struggle

When solving a difficult proof or integration problem, deliberately model calm uncertainty:

“I'm not sure yet which approach is best, so let's test a few ideas.”

This helps normalise challenge rather than signalling that difficulty means failure.

2. Protect students when answers are wrong

Respond to incorrect answers with:

“That's useful because it highlights an important idea.”

Acknowledge the contribution before analysing the error. This helps maintain psychological safety and reduces the risk of negative emotional reactions spreading through the class.

3. Make confidence visible

Regularly ask students to share partial progress:

“What's one thing you're confident about so far?”

This allows productive thinking and persistence to become socially visible, helping positive classroom norms spread through the group.
