Some of you may remember a post I did a little while ago on John Hattie. We had been looking at his research on what teachers could do to make a difference to their students and like me a lot of you found it super interesting. I found it particularly shocking that in his 2009 research class size was at the bottom of the list. I had spent my whole school life wishing for a small class because everyone had said that the smaller the class the better the outcomes- but Hattie's research was challenging this.
The table to the left is the same as the one I posted over on my Instagram, with feedback having the greatest effect on the children and the physical attributes of the classroom having the least impact.
After chatting to some of the commenters on the post and direct message, I thought it would be interesting to try and find an updated list.
The images below are screenshots that were last updated in 2021- again they are linked below. I haven't included every single influence as there are hundreds, but what I have done is included the biggest effect size, shown that feedback has moved down the list from the 2009 version and then displayed the smallest effect sizes as well. This is in no way an academic post to try and explain the what's and why's of what is going on here, but I know a few of you were interested to see any changes so I have just provided you with the information I have found!
In the 2021 tables, one that stood out to me was the presence of mobile phones. I am guilty of working with it sat right next to me and it is by far the biggest distraction, and although I know this, it brings it home when it is actually written down in front of you! When I am in lectures and seminars I make a conscious effort not to have it within grabbing reach so that I can focus my full attention on what I am meant to be learning! But when it comes to independent working, it is all too easy to pick it up and think 'oh I'll just have a quick check' and then 30 minutes later you're somehow watching the giraffes being fed at London Zoo!!
Let me know in the comments on this post what you think of this, and please use the second link below to see the full table of effects- remember, the bigger the effect size, the bigger the effect it has on the students!
