A couple weeks ago I wrote about John Hattie’s work developing a ranking system that rated the effectiveness of a variety of influences on student learning. If you didn’t get a chance to read that post, you can find it here: Research, meta-analysis, and John Hattie. As I shared in that post, sometimes it’s overwhelming to begin looking into educational research for ideas to implement in our classroom. What I love about Hattie’s work is that he does most of the heavy lifting for us. He has combed through nearly 1200 research studies, and has a list of 195 influences that can relate to learning outcomes.

In today’s post I’m going to look at a couple of the most promising influences on learning outcomes. These are the things that we might use to find the answer to the never ending question of “What works best in education?” As a reminder from last week’s post, mileage may vary based on the background and influences in your classroom, but the larger the effect size in Hattie’s meta-analysis, the more likely it is to impact learning for the students in your class, and an average effect size is a 0.40. Anything over a 1.0 would have a huge impact.

• Teacher Estimates of Achievement (Effect size 1.62): We all naturally make judgements about students. For a long period of time, research has shown that teachers have lower expectations for students from low-income families and black students. In an interesting study out of Brown University, boys and girls who start school with the same types of behavior problems generally end up in very different places down the line. Boys in this group have lower test scores and lower graduation rates. Why does this happen? Boys from this background are not expected to be successful, so they aren’t. I’ve always loved the Henry Ford quote “Whether you think you can or you think you can’t, you’re right.”  What if we change that quote slightly – Whether you think they can or think they can’t, you’re right. The research is solid – when we believe that our students can learn and be successful, they are much more likely to live up to it. We’ve all had moments where we think (or say) “That poor kiddo just can’t do it.” Be aware of these thoughts, because they can impact your attitude. Our attitude affects our choices, and our choices have consequences.The reality is that if we believe we can make a difference for these kids, they are more likely to be successful!
• Collective Teacher Efficacy (Effect size 1.57): This refers to a group of teachers who believe that through working together, they are able to develop students’ abilities. Basically, if you believe in yourself and your own abilities, you are much more likely to be able to help your students to learn and grow. When a teacher has a high level of efficacy, that teacher is likely to have a higher level of effort and persistence, be more willing to try new teaching approaches, set more challenging goals for themselves and their students, and attend more closely to the needs of students who require extra attention.
• Self-Reported Grades (Effect size 1.33): Another name for this strategy could be student expectations – how prepared do students believe they are t show what they know? Children are generally pretty accurate in predicting how well they will do on a test prior to taking it. As the teacher, you would then find out what those student expectations are, and then pus the student to exceed their expectations (Growth Mindset!). A way to do this would be to ask a kiddo to write down their predicted score on the top of an exam prior to taking the exam.  se that information to engage your students to try to do even better than what they predict!

There are many more influences in Hattie’s meta-analysis, but I wanted to point out these three because they are all more than 3 times the average effect size, they are all relatively easy to implement, and especially in the case of the first 2, they are entirely reliant on our own beliefs about students and learning!  We’ve talked a lot about growth mindset in education – to implement these influences, we need to practice our own growth mindset!

What are your thoughts?  Do any of the three influences above strike a chord with you?  What can you do with this information to impact the learning of your students?  In a recent interview, I heard one teacher talking about the importance of starting right now.  Sometimes in education we’re tempted to wait until after a break, or until the end of the semester.  The teacher shared that in her opinion, if you know better, why wouldn’t you want to do better?  Take something from this post, and think carefully about how you could use it for the benefit of your kids, and then… Just do it!  Don’t put it off, dive in!
