Collective efficacy

Steph Curry shoots three-pointers like no one else. His consistency and excitement cultivate confidence within himself and his team. This confidence, or efficacy, helps both Curry and the Golden State Warriors stay motivated and resilient.

Collective efficacy is born as a result of experiencing success as a team, which positively influences the team’s belief that there will be more success in the future. We see this in sports all the time, as well as other organizations.

As I stated before, just as Curry has forced basketball players to think more strategically about how they can effectively make points and work as a team, John Hattie is helping educators rethink how to be more effective in the classroom. According to his research, collective teacher efficacy has an effect size of 1.57, which is quadruple the .40 necessary for one school year’s worth of growth.

As stated in Leading Impact Teams, collective teacher efficacy is when teachers work together to build the confidence that they can get all students to advance in learning. These teachers truly believe that collectively they have the capacity to promote successful student outcomes within their school. Like Curry, they have confidence because they’re using proven strategies that give them the biggest bang for their buck. Good results beget good results, which builds not only the professional capacity of the team, but also their collective efficacy (i.e. their belief they can promote student achievement).

I really enjoy drawing a parallel between the effectiveness of Steph Curry’s basketball strategy and the educational strategy of focusing on good teaching strategies and collaboration so collective teacher efficacy is fostered. Just as shooting threes instead of dunking the ball is an efficient tweak for scoring more points without changing the structure of the game (the game wasn’t made longer, they didn’t have to make a four-point shot, etc.), educators can make choices that allow them to truly work smarter, not harder, and help students achieve greater heights without large-scale and expensive educational reform.

Shoot more threes

Steph Curry has changed basketball by showing players and fans what should have been apparent all along: If you practice really hard and get really good, shooting a three-pointer is far more beneficial than taking a two-point shot.

Growing up in the late 80’s and 90’s, I thought the slam dunk was the most thrilling offensive move. But no matter how high a player could jump off the ground–no matter how acrobatic his trajectory–a dunk was only two points.

Of course, three-point shots have been around forever, and there have been many great shooters throughout the history of the NBA. Curry is different though. Not only has he perfected the three-point shot to almost superhuman proportions, he’s changing how other players approach the game. Further still, he’s influencing how this generation’s young people practice. Yeah, dunks still look cool, but the three-point shot is now even more cool. Better yet, you get three points instead of two.

I was thinking about this the other day in relation to education. There are a lot of two-point shots being taken. Maybe even some slam dunks and the occasional alley-oop. Looking at John Hattie’s ranking of effect sizes, these two-pointers could be any number of things:

  • homework
  • use of PowerPoint
  • summer school

These three random examples each have less than a 0.40 effect size, so according to Hattie’s research, you’re not getting a lot of bang for your buck by using them in the pursuit for student achievement.

Just as Curry has forced basketball players to strategically think about how they can more effectively make points for their teams, Hattie is helping educators rethink how to be more effective in the classroom. Every strategy has an effect (just like every made shot within the three-point line is two points)–what’s important is using precious instructional time to choose the strategies that reap the greatest rewards. According to Hattie, these “three-point shots” are:

  • teacher estimates of achievement (1.62)
  • collective teacher efficacy (1.57)
  • self-reported grades (1.33)

Teachers and administrators must shoot fewer two-pointers and begin shooting more three-pointers. Here and here are good places to start in this pursuit.
